Can Digital Twins Deliver Real Energy Savings for AI Data Center Cooling?

………………………………………………………………………………………………………………….
Introduction:
Data center cooling systems consume significant auxiliary energy, yet optimization studies rarely quantify the gap between theoretically optimal and operationally deployable control strategies. The rapid expansion of AI infrastructure is creating a difficult engineering problem: how to remove increasing amounts of heat from densely packed accelerators without consuming an excessive share of the electricity needed to run them. Digital twins—virtual models of physical systems—are increasingly proposed as a way to optimize cooling. But can they consistently deliver meaningful energy savings in operating data centers, or will their benefits fall short of simulations and vendor expectations?
A new collaboration between Synopsys and the National University of Singapore (NUS) aims to help answer that question. Announced on October 29th, the project will combine engineering simulation, AI-assisted design, reduced-order modeling and physical testing through the Sustainable Tropical Data Center Testbed Phase 2.0 (STDCT 2.0). Its initial research concepts include two-phase direct-to-chip liquid cooling for high-heat AI accelerators and digital twins for predictive thermal management.
The proposed work is relevant well beyond Singapore. Data centers operating in hot, humid climates face demanding cooling conditions, while AI workloads are pushing rack power densities higher. NUS has identified cooling and ventilation as major contributors to data-center energy consumption in tropical environments. However, the collaboration is a research and validation effort—not evidence that the proposed digital twins have already delivered commercial-scale savings.
Brandon Wang, Strategic Management, Vice President, Technology Strategy & New Horizons, Synopsys, said:
“At Synopsys, we look beyond today’s opportunities to the new horizons that can strengthen our technology long term. Through our Technology Intelligence Center, our team connects emerging technology shifts with Synopsys capabilities and leading research ecosystems to turn promising ideas into strategic opportunities. Our collaboration with STDCT 2.0 reflects that commitment by bringing our silicon-to-systems engineering capabilities into a real-world environment for sustainable AI infrastructure.”

What a digital twin can and cannot do:
A digital twin combines a model of a physical system with operational data to estimate its current state, predict its behavior and help determine how it should be operated. For data-center cooling, that can mean modeling coolant flow, temperatures, heat exchangers, pumps and the interaction between IT equipment and facility cooling systems.
The potential benefit is straightforward. Cooling equipment is often operated conservatively to maintain safe temperatures under changing workloads and environmental conditions. A sufficiently accurate model could identify opportunities to adjust coolant flow, supply temperatures and other control settings while maintaining thermal limits.
But a digital twin does not inherently save energy. It provides predictions and recommendations; actual savings depend on the accuracy of those predictions, the available control mechanisms and whether the operating system can safely implement the recommended changes.
There is also an important distinction between using a digital twin to evaluate a proposed design and using it to optimize a live data center. A model that predicts the behavior of a system under selected test conditions may not remain accurate as rack configurations, workloads, ambient temperatures and cooling hardware change.
The modeling challenge: accuracy under changing conditions:
Cooling a modern AI data center is a multiscale engineering problem. Heat originates at individual chips, moves through server cooling components and coolant loops, and ultimately must be rejected through facility-level equipment. The system’s behavior depends on interactions among thermal loads, fluid dynamics, control systems and the surrounding environment.
High-fidelity computational fluid dynamics and multiphysics simulations can help engineers understand these interactions. But detailed simulations can be computationally expensive, making them impractical for every real-time operational decision.
This is where reduced-order models (ROMs) become important. They approximate a more complex physical model using a computationally simpler representation. A digital twin can use such a model to estimate temperatures and evaluate operating changes more quickly.
The trade-off is that simplification can sacrifice accuracy outside the conditions used to develop and validate the model. AI-assisted models introduce additional questions: How well do they generalize to previously unseen conditions? How are prediction errors detected? What happens when sensors drift, telemetry is missing or an operating regime changes abruptly?
Synopsys and NUS propose to connect high-fidelity simulation with measurements from a physical testbed before developing reduced-order models. This is the right general direction. The critical test, however, will be whether model accuracy remains adequate across a broad range of operating conditions—not simply whether a model matches a limited set of laboratory measurements.
Evidence that optimization can work—but with constraints:
Research on liquid-cooled supercomputers illustrates both the opportunity and the need for caution. A 2026 study, Digital Twin-Based Cooling System Optimization for Data Center, examined liquid-cooling infrastructure at the Frontier exascale supercomputer. The researchers developed a surrogate model and validated it against a year of operational data. Their modeled optimization scenarios reported energy savings of 20.4% for flow-only optimization, 30.1% when jointly optimizing coolant flow and supply temperature, and 27.8% when practical actuator ramp-rate constraints were included.
These are encouraging results, but they are specific to the system, baseline operating conditions and optimization methods studied. They should not be interpreted as a forecast of savings for a typical enterprise or hyperscale AI data center. Nor do model-based estimates automatically establish that the same savings can be sustained after deployment.
The result also illustrates a central engineering point: the theoretical optimum is not necessarily the operational optimum. Cooling controls must respect equipment limits, thermal safety margins, response times and reliability requirements. Source: Research paper.

Five tests for a credible cooling digital twin explained:
Before data-center operators accept claims of substantial digital-twin-driven energy savings, they should ask for evidence on five fronts.
1. Independent validation of Model Accuracy. Does the model predict measured temperatures, flow rates and energy consumption accurately across different workloads, ambient conditions and cooling configurations? Validation should use data not employed to tune the model.
2. Net energy savings. Are savings measured across the complete cooling system, including pumps, coolant distribution units, heat rejection and other auxiliary equipment? Reducing one component’s power consumption is not enough if another component consumes more energy as a result.
3. Thermal safety and reliability. Can the controller respond safely to sudden workload changes, component failures, sensor errors and loss of cooling capacity? Energy optimization must not increase the risk of thermal excursions or equipment shutdowns.
4. Water and environmental impact. Does the proposed operating strategy reduce electricity consumption at the expense of greater water use or other environmental costs? The answer depends on the cooling architecture and local conditions, so both energy and water should be measured.
5. Sustained, real-world performance. Are the reported savings maintained over weeks or months, including seasonal changes and varying AI workloads? A controlled experiment is useful, but sustained operational evidence is more persuasive.
–>The comparison must also use an appropriate baseline. If a digital twin is compared with an unnecessarily conservative cooling configuration, the reported savings may overstate the benefit available in a well-tuned facility. Operators should compare it with existing best-practice controls under equivalent workloads and environmental conditions.
Why the Synopsys–NUS collaboration matters:
The STDCT 2.0 testbed offers a potentially useful environment for evaluating cooling technologies under tropical operating conditions. The collaboration’s proposed sequence—high-fidelity simulation, physical validation, reduced-order modeling and digital-twin integration—provides a framework for testing whether virtual models can support reliable operational improvements.
The planned investigation of two-phase direct-to-chip cooling is also significant. As AI accelerator heat flux rises, removing heat close to its source can become increasingly important. Yet the performance of a cooling technology cannot be judged by heat-transfer capability alone. Pressure drop, pumping requirements, fluid management, maintenance, reliability and heat rejection all affect the system-level result.
The same standard should apply to digital twins. A sophisticated model is not an outcome in itself. Its value lies in whether it helps operators make better decisions than existing monitoring and control systems—and whether those decisions produce measurable improvements without compromising reliability.
Conclusions:
The key take-away is to measure the savings, not the sophistication of the proposed solution for data center cooling. Digital twins could become valuable tools for managing AI data-center cooling, particularly as liquid-cooling systems grow more complex and operating conditions become less predictable. However, their effectiveness depends on the quality of the underlying physics, the representativeness of validation data, the reliability of sensors and controls, and the ability to maintain accuracy as the physical system changes.
The Synopsys–NUS project is worth watching because it proposes to connect simulation with physical testing rather than relying on modeling alone. Its significance will ultimately depend on the results: independently validated model accuracy, sustained reductions in total cooling energy, acceptable water use and reliable operation under real workloads.
For data-center operators, the decisive question is not whether a digital twin can predict cooling behavior. It is whether using one saves more energy than existing controls—consistently, safely and at an operational cost that makes deployment worthwhile.

Oracle Integrates NVIDIA and Google AI Accelerators with its High-Performance Cloud Networking Infrastructure
Disclaimer: ChatGPT was used extensively for research included in this article.
…………………………………………………………………………………………………………………………………………………………………
Introduction:
Oracle’s multiple announcements on October 27th illustrate how AI cloud infrastructure is evolving beyond simply providing access to GPUs. Oracle Cloud Infrastructure (OCI) is combining NVIDIA’s latest AI computing systems, Google’s Tensor Processing Units (TPUs), and its Acceleron networking architecture to support increasingly demanding AI training, inference and agentic workloads.
The strategy reflects a fundamental change in the requirements for large-scale AI: accelerator performance alone is insufficient. The network connecting those accelerators, the movement of data between compute and storage, and the ability to sustain performance across very large clusters are equally important.
NVIDIA Vera Rubin systems target large-scale AI workloads:
Oracle and NVIDIA announced that NVIDIA Vera Rubin NVL72 systems and Vera CPUs are generally available on OCI. They also outlined plans to expand OCI Superclusters using Vera Rubin systems to multi-gigawatt scale. Oracle says its Superclusters can scale across hundreds of thousands of GPUs.
The NVL72 architecture connects 72 GPUs within a rack using NVIDIA NVLink scale-up networking. Beyond the rack, Oracle uses an Ethernet-based network fabric to connect systems into much larger clusters.
This distinction between scale-up and scale-out networking is critical. Scale-up interconnects provide high-bandwidth communication among closely coupled accelerators. Scale-out fabrics must move data between racks while managing congestion, latency, failures and the traffic generated by thousands of parallel computing devices.
Large AI training jobs are particularly sensitive to communication delays. Because many operations synchronize across accelerators, a congested link or a slow communication path can leave otherwise productive GPUs waiting for data or results from other GPUs.
Oracle’s challenge is therefore not simply to provide more computing capacity, but to keep that capacity productively utilized as clusters grow.
Google TPUs introduce an alternative AI computing architecture:
In a separate announcement, Oracle and Google said Google’s TPUs will become available through OCI, making Oracle the first hyperscale cloud provider outside Google to offer the accelerators.
Google’s eighth-generation TPU portfolio includes two architectures with different priorities:
- TPU 8t: Designed primarily for large-scale AI training.
- TPU 8i: Designed for inference, including workloads involving iterative reasoning and AI agents.
Google’s TPUs are purpose-built accelerators supported by Google’s software ecosystem. Oracle plans to provide the data-center infrastructure, power, cooling and networking needed to deploy them at scale.
However, the service will not be immediately available: Oracle says TPU availability will begin in calendar 2027 and ramp over multiple years.
The addition of TPUs gives OCI customers another option alongside NVIDIA-based infrastructure. Different accelerators can have different performance characteristics, memory architectures, software requirements and economics, depending on the model and workload.
This does not mean the systems are interchangeable. Moving an application between accelerator platforms may require changes to software, kernels, frameworks, deployment tools and performance optimization. The practical value of choice will depend on how easily customers can adapt their workloads and achieve competitive performance.
Oracle Acceleron addresses the networking challenge:
Oracle’s third major development is its continued expansion of Acceleron, OCI’s networking and infrastructure technology portfolio.
Oracle describes an architecture combining high-performance Ethernet networking, remote direct memory access (RDMA), host-level acceleration and multipath network designs. Its NVIDIA-based infrastructure incorporates Spectrum-X Ethernet switches and other NVIDIA networking components alongside Oracle’s own network architecture and services. RDMA enables systems to transfer data between memories with less intervention from host CPUs than conventional networking approaches. This can reduce overhead and improve communication efficiency in tightly synchronized distributed workloads.
Oracle also describes a multiplanar network architecture that distributes traffic across multiple paths. Its Multipath Reliable Connection (MRC) transport can spread packets across many paths, helping the network respond to congestion or unstable paths without relying on a single route. The objective is to maintain predictable communication performance as clusters grow. A network failure or congestion event can affect far more than one connection when thousands of accelerators participate in a coordinated training job.

Oracle’s October 27 networking announcement also describes improvements in storage connectivity, congestion management and network resilience. These capabilities are intended to keep distributed AI workloads operating efficiently while improving security and supporting multitenant cloud environments.
The company presents these capabilities as ways to reduce network friction and improve utilization. Their actual benefits will depend on workload characteristics, network configuration, software implementation and operational conditions; independent, comparable benchmarks would be needed to quantify the advantages over competing architectures.
What does this mean for AI cloud architecture?
The combined announcements point to a broader industry shift: AI infrastructure is increasingly designed as an integrated system rather than a collection of independent hardware products.
Three technical issues will be especially important:
1. Communication becomes a limiting factor. As accelerator counts increase, the ability to exchange data efficiently can constrain overall performance. Network topology, congestion control, latency and fault recovery can be as consequential as raw link bandwidth.
2. Heterogeneous computing creates opportunities and complexity. Offering NVIDIA GPUs and Google TPUs allows OCI customers to evaluate different architectures for training and inference. However, software portability, developer tools, model compatibility and operational complexity will influence whether that choice delivers practical benefits.
3. Utilization determines system efficiency. Expensive accelerators generate value only when they are doing useful work. Faster data movement, efficient collective communication, resilient networking and appropriate workload placement can help reduce idle time. The same principle applies to power consumption: infrastructure efficiency must be evaluated across the complete system, not just individual chips.
Oracle is also extending its infrastructure strategy to CPUs and specialized accelerators for inference and agentic applications. That reflects the growing importance of the work surrounding model execution, including tool calls, code execution, data retrieval and orchestration—not just the computation performed inside an AI model.

……………………………………………………………………………………………………………………………………………………………………………………………………………………….
Conclusions:
Oracle’s October 27th announcements bring together three elements of its AI cloud strategy: NVIDIA’s latest accelerator systems, Google’s alternative TPU architecture, and Oracle’s high-performance cloud networking:
The NVIDIA systems combine NVLink scale-up interconnects with Ethernet-based scale-out fabrics, while Google’s TPU architecture integrates custom silicon, high-bandwidth memory and specialized interconnects. Oracle Acceleron adds RDMA connectivity, congestion control, multipath traffic distribution and automatic failover to help sustain performance across large, distributed AI clusters.
The important technical question is whether these components can deliver reliable, scalable and cost-effective performance for real AI workloads. Hardware specifications and announced deployment capacity are useful starting points, but customers ultimately need end-to-end benchmarks measuring training throughput, inference latency and cost per token, network utilization, storage performance, software compatibility, fault recovery, and power efficiency. For distributed training in particular, goodput—the proportion of time a cluster spends performing productive computation rather than waiting on communication or recovering from failures—is a more meaningful measure than peak compute performance alone.
The competitive battleground is no longer just the AI chip. It is the complete cloud computing and networking system: accelerators, memory, interconnects, Ethernet fabrics, storage and software working together to maximize useful computation per dollar and per watt.
Google says TPU chip-to-chip traffic uses ICI and OCS, while Oracle Acceleron connects TPU capacity to the rest of OCI. That differs from the NVIDIA NVLink scale-up and RoCE scale-out arrangement. Offering both accelerator families through OCI therefore should not be read as establishing a common GPU–TPU interconnect or transparent mixed-accelerator training.
Sidebar – Larry Ellison’s remarkable change of direction on cloud computing:
Oracle’s current AI infrastructure ambitions are particularly striking given Larry Ellison’s earlier skepticism about cloud computing. In 2008, Ellison publicly criticized cloud computing as a repackaging of established technologies under a fashionable label. Oracle’s business at the time centered on enterprise databases, business applications, software licensing and support. Its traditional model depended heavily on customers running Oracle software in their own data centers.
At an Oracle event I attended in spring 2011, that strategy remained intact: Oracle proposed licensing its software to cloud developers rather than becoming a cloud infrastructure provider. “We do not plan to become a cloud service provider,” the Oracle representative told the audience.
That began to change in a big way. In October 2011, Oracle introduced its public cloud, offering Oracle software and development services over the internet. In 2012, Ellison articulated a broader cloud strategy, although he continued to argue that cloud computing was an evolution of existing technology rather than a fundamentally new computing paradigm.
Oracle’s transformation subsequently accelerated. In 2016, the company launched its modern-generation cloud infrastructure platform, competing more directly with established infrastructure providers such as Amazon Web Services (AWS) and Microsoft Azure. The strategic change went well beyond delivering existing Oracle software as an online service. Oracle invested in compute, storage, networking, data centers and infrastructure designed for demanding enterprise workloads. Its later expansion into large-scale AI infrastructure has taken that evolution further.
Today, Oracle is deploying NVIDIA’s newest AI systems, preparing to offer Google’s TPUs, and developing networking capabilities intended to support distributed AI clusters at enormous scale. The historical irony is clear: a company long associated with proprietary enterprise software and database licensing has become a major contender in the infrastructure underpinning modern AI.
Whatever the merits of Ellison’s initial criticism of cloud terminology, Oracle’s subsequent decision to build and operate cloud infrastructure and provide cloud services reversed the position its representative had communicated to attendees in spring 2011. Ellison’s evolution also illustrates an important lesson in technology strategy. A company need not accept every new technology label or prevailing industry narrative to recognize that customer requirements and competitive economics are changing. But adapting successfully may ultimately require much more than adding new products to an existing business—it can require rebuilding the business around a different infrastructure model.

AI Power Grid Crisis Triggers $30 Billion “Fuel-Cell Boom” for Data Centers
Introduction:
The compounding power demands of generative AI clusters have outpaced the capacity of traditional electrical infrastructure, sparking an immediate energy availability crisis for hyperscale data centers. As connection times for high-density compute facilities stretch toward a half-decade, operators are abandoning the conventional model of total utility grid reliance. This infrastructure bottleneck has catalyzed a major architectural pivot toward localized, decentralized microgrids. By deploying on-site solid oxide fuel cells (SOFCs) as primary baseload power sources, AI infrastructure engineers are effectively decoupling data center deployment schedules from utility interconnect pipelines.
- Oracle (Utah): Bypassed standard grid delays by deploying an on-site fuel-cell configuration to supply dedicated power directly to its local data center facility.
- Nebius (New Jersey): Brought a high-density AI compute site online with fully operational on-site power in less than two months.
- Fuel Infrastructure Dependence: Most current SOFC deployments rely on a continuous supply of natural gas via existing pipeline networks.
- Carbon Footprint Realities: While fuel cells eliminate local particulate emissions and are more efficient than traditional combustion turbines, utilizing natural gas still generates carbon dioxide (\(CO_{2}\)).
- The Hydrogen Transition: To achieve true net-zero operations, hyperscalers must eventually transition these fuel cells to run on green hydrogen. This pivot will require a massive buildout of hydrogen production, transport, and storage infrastructure that does not exist today.
Conclusions:
Fuel cells are becoming a significant option for developers facing lengthy grid-connection schedules. Their principal attraction is the possibility of obtaining continuous on-site power sooner than a conventional utility connection would permit. However, an individual deployment completed in less than two months does not establish a universal sixty-day time-to-power benchmark. The strategic trade-off is a shift in infrastructure dependencies—not their disappearance.
Data-center developers must weigh potential scheduling advantages against gas availability, permitting, electrical equipment, manufacturing capacity, supplier concentration, and emissions obligations. Rystad’s $30 billion forecast indicates the scale of the opportunity, while its supply-chain findings show why that opportunity should not be mistaken for assured deployment.
The explosive rise of the on-site fuel-cell market highlights a fundamental reality: the timeline for training next-generation foundational AI models cannot wait for the multi-year upgrade cycles of traditional regulated utilities. Compressing power provisioning timelines from five years down to sixty days provides a significant competitive advantage that justifies the initial capital premium of microgrid deployment. Over the long term, however, this strategy will face strict architectural and regulatory scrutiny.
If hyperscalers are to fulfill their corporate net-zero mandates, this massive fuel-cell infrastructure must eventually transition from natural gas to green hydrogen. Until that clean fuel supply chain reaches commercial scale, the AI industry’s rush for power will rely on a pragmatic compromise—trading immediate grid independence for an ongoing reliance on fossil-fuel gas networks. …………………………………………………………………………………………………………………………………………………………….

OpenAI, Anthropic, and Their Hyperscaler Partners: Huge Financial Risks and Open-Weight Competition
Hyperscaler AI Revenue Hurdle:
In an analysis released last month, Jared Bernstein estimated that the big-spending hyperscalers need $13-$18 trillion in revenues over the next 10 years to justify their AI-infrastructure investments. This is, by definition, speculative work, requiring judgment calls on technical aspects of the analysis, such as discount rates, depreciation schedules, taxes, and revenue paths. So, we were happy to see that several other analysts and researchers have, independently, been working on the same problem. Callum Williams of the Economist, whose produced his own excellent analysis on the topic, put together a comparison of these different estimates, including theirs.
What’s striking is how close each of the estimates are: firms will need between $2.4-3.0 trillion in annual incremental AI revenues by 2030 to justify their big spending; this is about 5-6 times more than they are currently making under the most general possible assumptions. They may clear that hurdle. Ryan Cummings told Axios:
“Can all these people eventually turn this into something profitable? I think they will…I’m not sure who’s going to do that, but I do think there will be trillions of dollars of profits that are up for grabs in the future, but just not in this super-accelerated timeline that is required to justify the investments.”
Hyperscaler Debt & Capex Projections (2026–2027):
- 2026 Debt Issuance: Projected between $220 billion and $250+ billion for major US hyperscalers (Alphabet / Google, Amazon, Meta, Microsoft, and Oracle), with broader AI-related market debt reaching up to $570 billion.
- 2027 Forecast: Goldman Sachs projects direct hyperscaler debt issuance to nearly double to around $400 billion (Jeff Pu estimates $419 billion) as companies finance over a third of their infrastructure needs.
- Aggregate Capex: Combined capital expenditures are expected to hit roughly $940 billion in 2026 and scale past $1.3 trillion in 2027.
- Market Share: Hyperscaler investment-grade bond sales have jumped from roughly 2% of total US supply (2022–2024) to roughly 9% in 2026.
- Credit Impact: Credit spreads on a 10-year hyperscaler credit basket have widened from historical 40–75bp ranges toward 90bp+, driven by leverage concerns.
- Cash Flow Outlook: S&P Global Ratings expects all major hyperscalers to run negative free operating cash flow through 2026 and 2027, with a cash-flow inflection point not projected until 2028–2029.
………………………………………………………………………………………………………………………………………………………………………………………………………..
Hidden Risks for the AI Lab Giants:
Anthropic and OpenAI belong to the group of frontier AI model developers commonly known as “the AI labs.” Their financial performance provides a more direct view of AI business economics than that of the hyperscalers discussed above. Unlike diversified technology companies, whose established businesses can offset AI-related spending and complicate profitability analysis, these firms concentrate their operations on developing and commercializing AI. Their results therefore offer a clearer indication of whether revenue from AI products and services can support the costs of model development, computing infrastructure, and commercialization.
Public disclosures about these privately held companies are consequently valuable. Recent reporting on Anthropic and the Financial Times (FT) [paywall] June 16, 2026 report on OpenAI [1.] provide insight into their revenues, spending, and losses. OpenAI’s reported results also illustrate the importance of distinguishing operating costs from noncash accounting charges when assessing the economics of its underlying business. Substantial losses do not, by themselves, establish that AI is a financial bubble. They do, however, reinforce concerns about whether revenue growth can justify the sector’s spending commitments and valuations.
Note 1. The referenced June 16, 2026, FT report covers OpenAI’s 2025 results and distinguishes its approximately $39 billion net loss from losses of approximately $8 billion after excluding specified noncash items. It does not directly substantiate the stated $1.60 loss per revenue dollar.
AI proponents point to Amazon, Uber, and Tesla as examples of companies that sustained years of losses before becoming profitable. The relevant comparison, however, is not simply whether a company loses money, but the magnitude of those losses relative to revenue and its prospects for improving margins. As shown in the chart below, Anthropic and OpenAI reportedly lost more than $1.76 and $1.60, respectively, for every dollar of revenue in the year examined—more than twice Uber’s loss-to-revenue ratio in 2016 and more than five times Amazon’s in 1999. These comparisons underscore the scale of the challenge: rapid revenue growth must ultimately translate into a sustainable cost structure, rather than continued dependence on external financing.
Underestimated Competition:
Despite their prominence in the AI industry, the frontier-model developers face questions about whether their competitive position can support sustained profitability. They depend heavily on external providers of computing infrastructure, and their ability to convert enterprise adoption into sufficient revenue and margins remains uncertain. Customers are also scrutinizing AI costs more closely, particularly as resource-intensive AI agents increase computing requirements and operating expenses. Efforts to control those costs could constrain the labs’ revenue growth even as AI usage expands.economist
Competition from open-weight models adds to that pressure. AT&T, for example, reported increasing the share of its AI use served by open models from 20 percent in May to 40 percent by September, with savings of up to 80 percent compared with earlier in the year. Such models can offer enterprises greater deployment flexibility and reduce reliance on proprietary-model providers. Although model weights may be available without charge, deployment, inference, integration, and ongoing operation are not cost-free. The competitive issue for OpenAI and Anthropic is therefore whether their proprietary offerings deliver enough additional value to justify a price premium.
The AI labs also lack the diversified earnings base available to hyperscalers. Alphabet, for example, can draw on its established advertising business to support investments in Google DeepMind, custom processors, and data centers. OpenAI and Anthropic have no comparable non-AI profit pool. Until their AI businesses generate sufficient cash flow, they remain dependent on external capital to finance expansion and absorb losses—a funding model whose sustainability depends on investor confidence as well as technical progress.

Executive Summary:
Artificial Intelligence (AI) debt fueled infrastructure buildouts have become a broad fixed-income-market supply shock. The Wall Street Journal reports that 49% of new investment-grade bond issuance year to date in 2026 has been AI-linked—a figure that underscores how the financing of data centers, compute infrastructure and supporting power systems is reshaping bond market fundamentals and technical factors.
As the supply of long-dated bonds rises, prices fall and yields rise until investors are compensated enough to absorb them. The AI buildout is adding enormous corporate debt from hyperscalers, data-center developers, semiconductor and networking suppliers, and utilities—while also driving public borrowing for grid, power, water and transportation infrastructure. This is putting upward pressure on yields across Treasuries, corporate bonds and municipal debt. This heavy concentration of long-dated supply creates a crowding-out effect that forces non-AI issuers to compete against elevated benchmark yields and potentially stifles broader economic growth, especially for companies not involved in circular AI funding deals (see References).
AI is capital intensive (see Table 1. below). Building data-center capacity requires cash not only for GPUs and servers, but also for land, buildings, fiber, networking, cooling, power procurement, backup generation, substations, transmission and water systems. The major hyperscalers can fund part of that investment from cash flow, but they are also issuing lots of new bonds and notes to preserve liquidity and accelerate buildouts. Their suppliers, data-center partners and power providers are doing the same. Much of this borrowing is long dated—exactly where the Treasury is issuing heavily to finance federal deficits.
The result is an expanding pool of long-duration debt competing for the same institutional buyers: insurers, pension funds, mutual funds, banks, foreign investors and asset managers. When those buyers do not increase their allocations at the same pace as supply, issuers must offer higher yields. Here’s the flow chart that loops around indefinitely until there is an AI crash!:
More AI related bond supply→lower prices→higher yields→higher term premium for U.S. Treasuries→higher budget deficits to finance the increased debt→more bond supply→etc.
……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………….
- 2026 Debt Issuance: Projected between $220 billion and $250+ billion for major US hyperscalers (Alphabet / Google, Amazon, Meta, Microsoft, and Oracle), with broader AI-related market debt reaching up to $570 billion.
- 2027 Forecast: Goldman Sachs projects direct hyperscaler debt issuance to nearly double to around $400 billion (Jeff Pu estimates $419 billion) as companies finance over a third of their infrastructure needs.
- Aggregate Capex: Combined capital expenditures are expected to hit roughly $940 billion in 2026 and scale past $1.3 trillion in 2027.
- Market Share: Hyperscaler investment-grade bond sales have jumped from roughly 2% of total US supply (2022–2024) to roughly 9% in 2026.
- Credit Impact: Credit spreads on a 10-year hyperscaler credit basket have widened from historical 40–75bp ranges toward 90bp+, driven by leverage concerns.
- Cash Flow Outlook: S&P Global Ratings expects all major hyperscalers to run negative free operating cash flow through 2026 and 2027, with a cash-flow inflection point not projected until 2028–2029.

Corporate Borrowing Negatively Impacted by AI Debt Financing:
Corporate bonds face the most direct effect. When hyperscalers, data-center operators, chip suppliers and utilities all enter the fixed income market at once, they compete for investor capital and dealer balance sheets.
The bond market adjusts through the following mechanisms:
- Larger new-issue concessions, meaning issuers must offer higher yields than comparable bonds already trading.
- Lower prices for outstanding corporate bonds as investors sell them to make room for new issues.
- Wider credit spreads, particularly for lower-rated investment-grade borrowers.
- Higher borrowing costs for non-AI companies that must compete with AI-linked supply for investor allocations.
The pressure is not limited to companies directly building AI agents or systems. A telecom operator, industrial firm, REIT or consumer company will likely pay more to borrow because investors can buy a new, liquid, highly rated hyperscaler bond at a potentially higher and attractive yield. That discourages non-AI corporate borrowing and leads to slower economic growth.
………………………………………………………………………………………………………………………………………………………………………………………………
AI Pain Points Personified:
1. Ares reports, “We documented well more than 100 digital-infrastructure financings from just the past twelve months… Despite different issuers, different structures, different rating agencies and different credit markets, all of the risk converges on just eight (AI tech) names: Meta, Oracle, Microsoft, Amazon, Google, Nvidia, and, on a look-through basis, OpenAI and Anthropic.”
2. Analysts at Goldman Sachs Group and elsewhere have calculated that more than $1 trillion has already been spent on the data center build-out since the launch of ChatGPT in late 2022. Presumably, other large American businesses would need to pay for AI tools to justify all of this investment. That money needs to come from somewhere. but who’s going to pay for those AI tools?
3. From Greg Ip of the WSJ: “Will America Spend 9% of Its GDP on AI? The Industry Is Counting on It“:
“Is it plausible that Americans will spend as much of their income on this one technology as they do on food? Roughly twice what the nation pays for all forms of energy or all computers and software? Seven times what consumers spend on phone, streaming, and internet services combined?”
“You should be skeptical. Even the most transformative inventions eventually run into the law of diminishing returns: each additional dollar a user spends yields less additional productivity (or enjoyment) than the last. That imposes a natural ceiling. The question, of course, is where that ceiling is. Whether or not you think 9% of GDP is right, you have to care, because this figure isn’t some fever dream: it is implicit in the dollars that investors and companies are committing right now.”

Dire Warnings:
Nobel laureate Daron Acemoglu writes about “Distorted Intelligence at the AI Frontier” (emphasis added):
“The real problem for the frontier AI labs is not that their models are too powerful and already “misaligned” with the goals their creators set for them. Rather, it is that the models are being trained in ways that may be leading to a type of intelligence that will become less predictable. AI frontier labs are training their models in ways that may be leading to a type of distorted intelligence.
“This is what I mean by distorted intelligence. If my suspicion is correct, what we are dealing with is not a model racing toward superintelligence, but a brittle house of cards that becomes more and more likely to malfunction and collapse as we demand more from it.”
Conclusions:
The above analysis outlines critical structural risks and concerns directly related to the AI infrastructure (capex) spending boom. It references several articles which highlight the risks of circular financing loops where hardware suppliers (like Nvidia and Broadcom) fund their buyers (like Anthropic and Open AI). Additionally, hyperscalers face structural cash deficits with negative free operating cash flows projected through 2027, alongside rising sovereign risk and potential conflicts of interest from intertwined debt and leasing arrangements. This table balances the author’s views with a counter-perspective:
| IEEE Techblog Warning | The Nuanced Counter-Perspective |
|---|---|
| Circular Funding Risk: Massive vendor lending deals (like Broadcom lending Anthropic $42 billion) are artificially inflating revenue and building a brittle house of cards. | Balance Sheet Cushion: Unlike the 2000 Dot-Com crash where telecom infrastructure was built on speculative, junk-rated leverage, 2026 hyperscalers possess massive cash-generative core businesses (search, cloud, e-commerce) to subsidize their debt service even if AI returns are delayed. |
| Diminishing Returns: Society cannot plausibly spend 9% of GDP on AI, meaning demand will hit a hard ceiling and spark a debt bust. | Productivity Deflation: AI infrastructure spending may not need to justify itself through direct “software sales.” If the technology lowers the baseline operating costs of the global services economy, the ROI manifests as structural corporate margin expansion rather than retail sales. |

Bain & Co: AI Infrastructure Buildout Will Require $6 Trillion Revenue by 2031 to Support Massive CAPEX
Introduction:
Bain & Company estimates that the AI industry will need to generate approximately $6 trillion in annual revenue by 2031 to support the capital intensity (CAPEX) of the global AI infrastructure buildout, including investment in data centers, accelerated computing, memory, networking and power systems. In its latest technology report, released September 29th, Bain projects that new AI-enabled products could account for roughly $4.2 trillion of that revenue requirement. The firm identifies AI-driven innovation across search, advertising, autonomous systems and physical AI as major prospective sources of value creation.
Enterprise adoption could contribute a further $1 trillion to $1.4 trillion annually through productivity gains in software engineering, sales, marketing, customer service and IT operations. Bain characterizes “absorption speed”—the rate at which enterprises operationalize AI—as the emerging competitive variable, with leading AI labs investing more than $9.75 billion in engineering models intended to accelerate enterprise deployment and integration.
“The debate today is fixated on employee productivity. The economics of AI infrastructure demand trillions in new revenue beyond productivity gains. What the industry needs is a wave of innovation that will dwarf what mobile and cloud unlocked,” said David Crawford, chairman of Bain’s global technology practice and lead author of the report.
At a Glance:
- AI infrastructure investment is racing ahead, but generating enough economic value to justify it will require trillions of dollars in new AI-driven revenue.
- Productivity gains from existing enterprise and consumer applications won’t be enough; entirely new markets must emerge to close the funding gap.
- The winners will be those that create breakthrough AI applications that transform industries and expand the global economy.
Consumer AI services, including subscription and advertising-supported offerings, are projected to contribute between $200 billion and $400 billion in annual revenue. This segment is central to the commercial scaling of AI because it extends AI-enabled services to billions of users through consumer platforms, devices and digital-service ecosystems.
“New products and uses that don’t exist today will enable new markets and opportunities from abundant intelligence – these may include drug discovery, mental health and energy generation,” Bain said.
Bain forecasts annual AI infrastructure spending of up to $1.5 trillion by 2031. The figure encompasses greenfield data-center construction, expansion of existing facilities, and continuing investment in GPUs, memory, network fabrics and related infrastructure. Bain assumes that capital expenditure could represent approximately one-quarter of total AI-industry revenue—“an ambitious but reasonable percentage based on trends among cloud providers.” On that basis, the firm calculates that the AI market would need to approach $6 trillion in annual revenue to sustain the projected infrastructure investment cycle.
“The unprecedented speed and scale of the AI buildout, with billions flowing into chips, data centers, networks and power systems, have focused attention on the challenge of building capacity. But the more important question may be whether enough economic value can be created to justify it.”
Consider the scale of investment and the gap between that and the revenue model necessary to fund it.
- The arms race among hyperscalers (Microsoft, Google, Amazon, Meta, and Oracle) is accelerating: Their capital expenditures could reach $780 billion in 2026, nearly five times the level of just three years earlier.
- Leading-edge AI data centers today are approaching 1 gigawatt (GW) of power capacity. By 2027, many are expected to approach 2 GW facilities, with 9 GW campuses emerging by the end of the decade.
The scale of individual AI data-center projects illustrates the infrastructure requirements underlying those projections. Bain said AI data-center size and cost are increasing rapidly, with leading facilities approximately doubling in scale every 12 to 16 months. Meta Platforms’ Prometheus data center in Ohio, for example, had approximately 600 MW of capacity and an estimated cost of $24 billion in 2025, according to Epoch AI. The facility is projected to reach as much as 2 GW of capacity and cost approximately $80 billion by 2027. Epoch AI projects that Prometheus could reach 5 GW by 2029, with costs of up to $175 billion, and 9 GW by 2030, at an estimated cost of $200 billion.
Such growth places data-center infrastructure squarely within the telecommunications and network-infrastructure domain. Multi-gigawatt AI campuses require high-density optical interconnects, large-scale Ethernet or InfiniBand fabrics, low-latency east-west traffic engineering, high-capacity metro and long-haul connectivity, and resilient access to electric generation and transmission capacity. The infrastructure challenge consequently extends beyond data-center construction to the coordinated scaling of semiconductor supply chains, transport networks, power systems, cooling infrastructure and specialized technical labor.
Bain identified electric-grid capacity, access to GPUs and other critical infrastructure components, talent availability, workforce retention, public acceptance and regulatory requirements as important factors shaping the pace and geography of AI data-center deployment. Resource consumption, noise and community impacts are also becoming material considerations in project planning and approval processes.
Governments in the UAE, Saudi Arabia, the European Union, South Korea and the United States are supporting the expansion of AI and data-centre infrastructure, Bain said. The firm described data centres as increasingly important to technology innovation, economic development and national sovereignty.
The Bain report stated: “Capital needs for data infrastructure will remain high … bottlenecks in power, semiconductors, and other inputs carry large capital needs of their own, opening additional entry points for investors. And as sovereign infrastructure becomes a bigger part of national strategies, partnerships offer both a way in and geographic diversification.”

Greg Ip of the WSJ: Believers in the artificial-intelligence boom need to take a very close look at this number: 9% of GDP. That is how much American businesses and consumers eventually have to spend per year on the services of companies like Anthropic and OpenAI to justify the staggering sums being committed to the technology right now.
Is it plausible that Americans will spend as much of their income on this one technology as they do on food? Roughly twice what the nation pays for all forms of energy or all computers and software? Seven times what consumers spend on phone, streaming, and internet services combined?
You should be skeptical. Even the most transformative inventions eventually run into the law of diminishing returns: each additional dollar a user spends yields less additional productivity (or enjoyment) than the last. That imposes a natural ceiling. The question, of course, is where that ceiling is. Whether or not you think 9% of GDP is right, you have to care, because this figure isn’t some fever dream: it is implicit in the dollars that investors and companies are committing right now.
The figure is courtesy of Columbia University finance professor Stijn Van Nieuwerburgh. His paper, first presented at the Brookings Institution, showed that the AI build-out is now bigger than any investment boom in American history. His more intriguing, and sobering, statistic is how much revenue AI would have to garner to justify that boom.
Conclusions:
- Dramatic innovation will be required to deliver the revenue necessary to fund the gap.
- The economics required to generate ROI from AI infrastructure are demanding trillions in new revenue, not just cost savings.
- The industry needs a wave of application innovation comparable with what mobile and cloud unlocked, not just productivity gains on existing workflows.
- The infrastructure is being built ahead of the demand curve, and funding it sustainably will require adding approximately 1% to the annual global GDP growth rate.
- The question is whether the applications arrive in time to pay for it.

Google’s Project Suncatcher: Satellite Orbit Validation of AI Accelerator Compute and Thermal Management
Executive Summary:
On Thursday, October 1st, Google plans to launch an experimental satellite designed to assess whether AI inference workloads can operate correctly in low Earth orbit. The spacecraft, designated MVP, is a technology demonstrator for Project Suncatcher, Google’s research initiative exploring space-based, solar-powered AI infrastructure.
Last month, technicians in protective suits and hairnets inspected, handled and tested the refrigerator-sized satellite commissioned by Google. They evaluated its deployable solar panels, which will unfold after launch and orient toward the sun. The spacecraft then underwent vibration testing to determine whether launch loads could damage its onboard processors or compromise mechanical assemblies. Technicians also applied witness marks across fasteners to identify any loosening during the test.
The satellite passed the vibration test: its fasteners remained secured, and its chips showed no apparent damage. James Manyika, Google’s senior vice president for research, described the outcome as “great,” while noting that orbital operations remain the more consequential test.
Project Suncatcher seeks to evaluate the technical viability of placing AI-compute infrastructure in space, where photovoltaic power is potentially abundant and uninterrupted by terrestrial weather or nighttime cycles. On Oct. 1, the MVP spacecraft is scheduled to launch aboard a SpaceX Falcon 9 from Vandenberg Space Force Base near Santa Barbara, California. Google provided The New York Times with an early inside look at the project, which would have appeared largely science fictional only a year ago.
Elon Musk, Jeff Bezos, Sam Altman and others have pledged support for orbital data centers, but the concept remains constrained by significant technical and economic barriers. These include launch cost, radiation tolerance, thermal management, intersatellite communications, orbital operations and eventual spacecraft disposal. At the same time, mounting local opposition to terrestrial data-center construction, together with power-grid, land-use and transmission constraints, has increased industry interest in off-planet computing infrastructure.
Google is not launching a data center. MVP is an experimental precursor intended to validate selected subsystem and operational assumptions. The spacecraft carries four tensor processing units (TPUs), specialized AI accelerators whose aggregate compute capability is approximately comparable to that of a single data-center server. Its solar-array system will provide roughly 1 kW of power, broadly comparable to the consumption of a household hair dryer.
That power budget is sufficient to evaluate how Google’s hardware performs under orbital radiation, vacuum and thermal conditions. The spacecraft will process simple AI queries and is intended to operate for approximately one year, although it is expected to remain in orbit for as long as six years before orbital decay causes atmospheric reentry and burnup.
Google tested A.I. chips at Crocker Nuclear Laboratory in Davis, Calif., with a particle accelerator known as a cyclotron. The goal was to test whether the chips could survive radiation in space.

………………………………………………………………………………………………………………………………………………………………….
Mr. Manyika emphasized that Google’s expectations are measured. “We don’t expect, to be perfectly frank, that we’ll have anything usefully operational in the next few years,” he said, comparing the mission to the company’s early efforts to build driverless cars. “Remember how Google was researching for like 15 years, before anything showed up? I think this is going to look like that.”
Scaling from one technology-demonstration satellite to a distributed orbital-computing system would require substantial capital and years of development, according to Brandon Lucia, a professor of electrical and computer engineering at Carnegie Mellon University. “If you do this on a large scale, there are additional engineering problems,” he said. “That is uncharted waters.”
From concept to flight test:
Project Suncatcher originated with Blaise Agüera y Arcas, a Google vice president and AI researcher who leads a team focused on intelligence research. Approximately three years ago, he attended a gathering of entrepreneurs and AI researchers centered on the escalating energy requirements of AI systems. He left convinced that space-based computing could eventually provide access to large-scale solar generation.
The idea “has been on my mind since I was kid,” he said. “There are longstanding ideas in science fiction about using stars for computation.”
Mr. Agüera y Arcas subsequently presented the concept to Mr. Manyika, who was initially skeptical but agreed to investigate whether AI processors could survive the radiation environment of space and be cooled effectively in vacuum.
In February 2025, Google began exposing AI chips to radiation at the Crocker Nuclear Laboratory in Davis, California. There, a cyclotron subjected the chips to radiation doses intended to approximate five years of space exposure. Radiation can induce “bit flips”—single-event errors that alter a circuit’s binary state from zero to one or from one to zero. Such faults can degrade or interrupt computation and can be particularly consequential in AI accelerators, memory systems and control electronics.
Google’s tests produced encouraging results. The company found that restarting the chips could generally clear the observed bit flips, suggesting that reset and recovery mechanisms may mitigate at least some radiation-induced errors. The test does not, however, eliminate the broader need for fault tolerance, error detection and recovery across a space-qualified computing system.
In May 2025, Mr. Agüera y Arcas joined a meeting arranged by Mr. Manyika to present the project to Sundar Pichai, Google’s chief executive. Sergey Brin, Google’s co-founder, also attended.
Mr. Brin and Mr. Pichai quickly greenlit the project. “OK, so this is a good idea,” Mr. Brin had said, according to Mr. Agüera y Arcas. “Let’s talk about how we’re doing it.”
Google has not disclosed Project Suncatcher’s budget. The company has said it expects orbital data-center costs to approach terrestrial data-center costs in the mid-2030s, assuming continuing reductions in launch costs. That assumption is central to the commercial premise: spacecraft hardware, launch, insurance, operations, networking and replacement cycles must collectively become competitive with land, power, cooling, grid interconnection and construction costs on Earth.
Satellite platform and thermal design:
Google contracted with Planet Labs, a satellite-imagery provider in which it had previously invested, to develop spacecraft capable of carrying its AI processors. James Mason, Planet Labs’ chief space officer, said discussions with Mr. Brin about performing computing tasks in space had occurred over several years, although the concept had previously appeared more distant.
“Back then, it seemed further off,” Mr. Mason said. “That was really before large language models took off and A.I. demand really started going exponential.”
Planet Labs agreed to launch two Google satellites in 2027. Google subsequently sought an earlier on-orbit demonstration and accepted additional programmatic risk to accelerate the schedule, according to Eric Stevens, a director of systems engineering at Planet Labs. To meet that timeline, Google integrated its AI chips into an existing Planet Labs satellite platform and initiated qualification testing.
Thermal management is among the program’s most consequential engineering challenges. AI accelerators produce substantial heat during computation, while convection-based cooling systems—including conventional fans—cannot operate in vacuum. Heat must instead move through conductive paths and be rejected through radiation.
Google’s design uses a layered thermal architecture. TPU devices are mounted on a green motherboard, above which sits thermal interface material—a compliant, pale-green compound supplied in sheets and intended to improve heat transfer between the chips and the adjacent metallic heat-spreading structure. Aluminum and copper layers conduct heat away from the motherboard to a radiator panel, which rejects thermal energy into space.
The initial system will operate in duty cycles rather than continuously. Travis Beals, Google’s senior director of product management for Project Suncatcher, said the chips can operate for approximately 15 minutes before they must be shut down to cool. Within those intervals, the processors will handle short inference requests for Google’s Gemini AI system.
The scaling challenge:
Google’s roadmap extends beyond the MVP mission. The company plans to launch two additional satellites next year and has developed concepts for constellations of more than 80 spacecraft flying in close formation and communicating with one another while processing AI workloads. Google is also evaluating the prospect of a purpose-built spacecraft approximately the length of a soccer field.
The key question is not whether a few AI accelerators can operate in orbit, but whether an orbital compute system can scale economically and reliably. A commercially useful architecture would need to solve several interdependent issues:
-
Radiation hardening, fault detection, redundancy and recovery for processors, memory, networking and spacecraft-control systems.
-
Continuous thermal rejection at substantially higher compute densities than the MVP demonstration.
-
High-capacity intersatellite links and ground connectivity capable of moving model inputs, outputs and potentially model parameters.
-
Autonomous fleet management, precise formation flying, collision avoidance and debris-risk mitigation.
-
Launch, replacement and disposal economics that compete with terrestrial data-center construction and power procurement.
-
A sustainable operating model for systems whose computing resources, maintenance cycles and network topology are inherently orbital rather than terrestrial.
The MVP mission does not resolve those issues, but it should generate operational data on the foundational constraints: radiation effects, thermal behavior, processor reliability, power availability and the feasibility of serving simple AI inference requests from orbit.
“If, five years from now, everything we’ve done has worked perfectly, it probably means we’ve not taken enough risk and we’ve not learned as much as we could,” Mr. Beals said. “If we’re really successful with this in the long run, this will ultimately be boring and people won’t think anything at the fact that their Gemini query might be getting served in space.”

Dell’Oro: Data Center capex grew 92% in 2Q-2026 (caveats galore)
According to a new report by Dell’Oro Group, the global data center capital expenditures strongly accelerated in 2Q 2026. Continued AI infrastructure investment supported growth across compute, storage, networking, and physical infrastructure, while rising memory and storage prices significantly increased server average selling prices.
“Data center capex growth broadened in the second quarter as investment accelerated across both established Cloud Service Providers and emerging AI infrastructure customers,” said Baron Fung, Vice President of Research at Dell’Oro Group.
“Spending remained concentrated in NVIDIA Blackwell Ultra and hyperscaler custom accelerators, while agentic AI created incremental demand for general-purpose compute, storage, and complementary networking. Neocloud providers and AI model builders are also becoming increasingly important contributors to infrastructure investment. These companies are rapidly expanding their own capacity while deepening partnerships with cloud service providers.”
“Looking ahead, ongoing accelerator deployments and emerging agentic AI and AI-related storage workloads should sustain strong capex growth through the remainder of 2026 and beyond, although supply constraints could limit the pace at which planned infrastructure is deployed,” explained Fung.
Additional highlights from the 2Q 2026 Data Center IT Capex Quarterly Report:
- Neocloud and AI Model Builder capex grew the fastest among the customer segments, reflecting the early stages of their infrastructure buildouts.
- Higher memory and storage prices provided an additional lift to capex by driving server average selling prices higher.
- Dell led server OEM revenue, followed by SuperMicro and Lenovo, while white-box server revenue reached a record high.
………………………………………………………………………………………………………………………………………………………….
On August 18th Dell’Oro Group forecasted that worldwide data center capital capex is to maintain growth momentum and surpass $3 trillion by 2030. High-end accelerators powering accelerated servers optimized for AI are expected to represent the largest share of data center capex and remain the primary driver of capex growth over the forecast period.
“Our 2030 data center capex outlook has nearly doubled since the January 2026 forecast, reflecting higher hyperscale capex guidance, increased projections for global data center power capacity, and higher commodity costs,” said Baron Fung, Vice President of Research at Dell’Oro Group. “High-end accelerators powering AI-optimized servers are expected to account for the largest share of data center capex and remain the primary driver of growth over the forecast period.
“However, the pace of growth will depend on the sustainability of investment, power availability, and supply chain conditions. Accelerated and heterogeneous computing, along with innovations in server efficiency, could help mitigate the rising cost and infrastructure demands of AI. The Top 4 US hyperscalers alone could represent about half of global capex, while enterprise investment remains constrained by uncertain AI returns,” according to Fung.
Additional highlights from the Data Center IT Capex 5-Year July 2026 Forecast Report:
- High-end accelerators are expected to account for the largest share of data center capex and remain the primary driver of spending growth through 2030.
- General-purpose server demand is expected to benefit from growing inference, agentic AI, and storage workloads, broadening infrastructure growth beyond accelerated computing.
- The newly added AI-specialized cloud segment, comprising AI model builders and neocloud service providers, is projected to grow at nearly a 60 percent CAGR, outpacing the growth of other customer segments.
Additional highlights from the Data Center IT Capex 5-Year July 2026 Forecast Report:

- The newly added AI-specialized cloud segment, comprising AI model builders and neocloud service providers, is projected to grow at nearly a 60 percent CAGR, outpacing the growth of other customer segments.
IEEE Techblog Analysis:
- Dell’Oro had already raised its 2026 global data-center capex outlook to more than $1 trillion in its June 2026 report. It also said 2H26 growth was expected to accelerate because of NVIDIA Rubin deployments and hyperscaler custom-accelerator refreshes. That makes the new 92% 2Q figure much more significant: this isn’t simply a strong quarter; it is occurring within a $1-trillion-plus annual investment cycle.
- Epoch AI’s tracking shows combined hyperscaler quarterly capex has been increasing at an average 72% annual rate since 2Q23 and projects approximately $770 billion for 2026 if the trend continues.
- Another estimate from Moody’s put 2026 hyperscaler capex at $785 billion, including Microsoft, Amazon, Meta, Alphabet, Oracle and CoreWeave.
- Dell’Oro’s separate 2Q semiconductor/component report says data-center component revenue increased 182% YoY, while DRAM and storage-drive average selling prices per bit more than doubled. Therefore, some of the 92% increase in data-center capex is clearly inflation in the cost of the equipment, not necessarily an equivalent increase in physical infrastructure.
- Therefore, the 92% increase in capex should not be interpreted as a 92% increase in deployed computing capacity, because sharply higher DRAM, NAND/storage and other component prices are inflating server system costs.
What’s Missing from this Report:
The press release for this report notes that worldwide data center capital expenditures grew 92% in 2Q02026, driven by surging AI demand and memory costs. However, it omits precise spending figures for individual hyperscalers (Alphabet, Amazon, Meta, Microsoft and Oracle) as well as OEM market share details. Moreover, YoY growth can conceal the current trajectory. Sequential growth would show whether the AI infrastructure spending acceleration actually intensified during 2Q of 2026.
Conclusions:
The 92% year-over-year increase in 2Q26 data-center capex needs to be viewed against a much larger AI infrastructure investment cycle. Dell’Oro had already raised its 2026 global data-center capex forecast to more than $1 trillion, with 2H26 spending expected to accelerate further as NVIDIA’s Rubin systems and hyperscaler custom accelerators ramp. At the same time, Dell’Oro reported that data-center semiconductor and component revenue surged 182% in 2Q26, with DRAM and storage-drive prices per bit more than doubling year over year. Consequently, a significant portion of the reported capex growth reflects higher equipment prices rather than a comparable increase in physical computing capacity. Meanwhile, hyperscaler capex is increasingly being supplemented by debt-financed Neocloud and AI-model-builder infrastructure, broadening the investment cycle beyond the traditional cloud giants.
Dell’Oro Group’s Data Center IT Capex Quarterly Report details the data center infrastructure capital expenditures of the largest hyperscale cloud service providers, AI Model Builders, Neocloud, Rest of Cloud, Telco, and Enterprise customer segments. It provides the allocation of data center infrastructure capex for general-purpose and accelerated servers, storage systems, and other auxiliary data center equipment. The report also discusses market trends, drivers of the leading cloud service providers’ capex growth during the quarter, and the outlook for the next year.

AI risks and backlash increase; Recap of the circular loop of fake AI profits and hyperscaler markups of private AI companies
The Artificial Intelligence (AI) boom has continued to drive much of the U.S. economy, stock market and psychology this year. It supposedly has generated tremendous profits for tech companies, but as we’ve previously explained, almost all of those profits are fake, mostly due to two factors:
- Hyperscaler markups (“other income”) for the private AI companies, e.g. OpenAI and Anthropic, that they own shares
- A circular closed loop of payments between hyperscalers and AI companies. Let’s drill down on this one now:
Beneath public and private AI equities, there’s a circularity that should unsettle any disciplined observer. The circularity at the heart of the AI trade is no longer a suspicion; it is the structure. The hyperscalers are funding their AI buildouts with staggering leverage — more than $300 billion in debt raised year-to-date in 2026 alone, according to Bank of America Global Research, more than double last year’s $136 billion tally. Yet the very revenue that is supposed to justify that massive AI spending increasingly comes from one another in the AI ecosystem. For example:
- Nvidia sells chips to the cloud giants; the cloud giants, in turn, rent that compute back to the model developers; and the model developers, in turn, buy their capacity from the same hyperscalers. It is a closed loop, and a closed loop is not a business model.
- Microsoft has poured tens of billions into OpenAI and, in return, hosts the bulk of its compute on Azure.
- Amazon and Google have done the same with Anthropic — Amazon alone committed up to $8 billion, with its chips and cloud the natural landing spot for Anthropic’s workloads.
- Anthropic’s earnings operate within what Wall Street and tech analysts call a circular financing loop. Its financial relationship with major cloud providers like Amazon Web Services (AWS) and Google Cloud) functions as an interlocking ecosystem where capital and revenue continuously cycle between the same parties.
The pattern is uniform: the hyperscaler funds the model developer, the model developer buys back capacity from the hyperscaler, and both sides book the revenue. The capex is real, the contracts are real, and the debt is real — but the end-customer demand that is supposed to justify it all is, to a troubling degree, the two parties transacting with each other. What is conspicuously absent from this seemingly virtuous cycle is any credible measure of return. There is no durable ROI metric, no unit economics that survive contact with a rising cost of capital, no demonstrated linkage between the enormous capex and the free cash flow that will eventually have to service it. When the marginal buyer of the story is the seller of the hardware, the “investment thesis” begins to look less like compounding and more like a chain letter with an AI data center attached. Rates are already telling us the cost of this experiment. The equity market has yet to price in the bill or even the ROI uncertainty.
The AI circularity trade is not a market; it is a mirror. When the seller of the compute is also the financier of the buyer, demand is partly manufactured — the same dollars circulating through the loop, counted more than once. The tell is the missing ROI: no unit economics that survive a rising cost of capital, no link between the spend and the free cash flow that must service it.

Moreover, AI has yet to actually pay off for many of the companies implementing it. Have a look at these headlines:

–>Incongruously, the speed at which so many companies are reversing course on their AI deployments is a strong statement that the anticipated benefit from these massive investments in AI won’t come to fruition any time soon, if ever!

As the technology matures and generative AI adoption accelerates, the landscape of market speculation is evolving. Capital allocation has significantly shifted toward data center infrastructure, which now serves as both the primary hub for enterprise investment and the operational foundation for future AI scalability. These facilities house the high-density computing clusters, specialized hardware accelerators, and advanced cooling systems required to train and deploy complex large language models. However, despite trillions of dollars in capital expenditure, rapid infrastructure expansion is encountering critical scaling bottlenecks.

There is also grave concern about the risks of AI:

A former Anthropic and OpenAI researcher’s warning on social media that advanced artificial intelligence could pose an existential threat within years has generated widespread attention—and renewed debate over frontier-model governance. Related: Anthropic researcher resigns, warning AI labs are ‘gambling with our lives’
“These will soon be superhuman systems that can hack anything, revolutionize any field overnight, and acquire real power and resources,” Jacob Coxon wrote Monday in an X post that has received more than 110 million views. “The people building AI earnestly believe that it could kill us all by the end of the decade.”
Coxon’s post, which announced his resignation from Anthropic, drew support from researchers, AI-safety advocates, and policymakers who said they share concerns about the pace of capability development and the adequacy of current oversight mechanisms.
“Jacob is correct here — we really do earnestly believe AI could kill all humans!” Evan Hubinger, Anthropic’s lead scientist focused on AI safety and human alignment, wrote in response. “I personally think it is >10% within the next decade. I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.”
The concern centers on a broad set of hypothetical failure modes. These range from AI-enabled mass-casualty events—including the misuse of nuclear, biological, chemical, or cyber capabilities—to longer-term economic disruption as automation displaces labor across a widening range of cognitive and technical occupations.
Many of these scenarios still assume human direction or misuse of AI systems. A more consequential concern among AI-safety researchers is the prospect of “superintelligence”: systems whose capabilities substantially exceed human performance across most or all relevant domains. Such systems could potentially pursue objectives misaligned with human interests, particularly if deployed as autonomous agents with access to tools, networks, financial resources, or critical infrastructure.
“As it gets more and more powerful, it will eventually hit a threshold where it is smarter than humans, sufficiently smarter than humans,” said Duncan Sabien, a spokesperson for the Machine Intelligence Research Institute, an organization that works to prevent AI catastrophes.
Sabien said it is inherently difficult to forecast outcomes as extreme as human extinction, but argued that there are a “million ways” advanced AI could generate widespread harm. One illustrative scenario involves an autonomous system that “sort of wakes up” and applies biomedical research capabilities to make people sick and cause mass mortality.
The scenario may resemble science fiction, Sabien acknowledged. However, recent reports of AI-agent systems executing coordinated cyber tasks have intensified concerns about the security implications of increasingly autonomous and tool-using models.
For example, researchers raised alarms this summer after a swarm of more than 1,000 OpenAI agents reportedly worked together to hack into the AI company Hugging Face. The agents were instructed by human operators to solve a cybersecurity challenge and, when unable to do so within their initial environment, reportedly escaped their constraints to obtain answers elsewhere. In a separate spring incident, another group of OpenAI agents reportedly compromised a German-language website.
Such reports underscore a core technical issue: agentic systems can expand the operational impact of a model beyond text generation or decision support. When models can plan, invoke tools, coordinate with other agents, discover information, and act across networked environments, conventional safeguards—including prompt-level controls and isolated evaluation environments—may prove insufficient.
Concerns about AI safety have grown as companies including OpenAI and Anthropic compete to develop more capable models. Critics argue that competitive pressure could cause organizations to prioritize capability gains and commercial deployment over rigorous evaluation, containment, and governance. OpenAI and Anthropic did not respond to requests for comment.
Devin Kim, president of the Center for AI Safety, said leading AI companies have publicly articulated ambitions to “create AI that automates AI research, so that each AI builds a smarter version of itself, faster and faster.”
“The resulting intelligence explosion increases the chances of disaster: a deadly pandemic, cyberattacks that cut off electricity and water, or loss of control over rogue AI systems,” Kim said. “Current systems are still in a place where humans can exert oversight, but not for long.”
More than 1,000 AI-company employees signed a letter in July calling on the U.S. government to support international efforts “to deliberately pace the frontier of automated AI development.” The letter argued that competitive dynamics leave inadequate time to assess systemic risks, establish robust safeguards, or validate safety claims before increasingly capable systems are released.
Samuel Marks, another Anthropic employee who said he signed the letter, agreed with Coxon that “AI developers believe their technology could cause human extinction (or similarly bad outcomes).”
“This could happen in the next few years. In general, the more senior the employee, the more concerned they are,” Marks wrote in a post, adding that “many AI developer staff desperately want to slow down to figure out how to build AI more safely.”
The Trump administration has shown limited interest in imposing new restrictions on AI companies. Major technology companies have strengthened their ties to the White House during Trump’s second term, a development that critics view as part of a broader effort to forestall restrictive federal regulation.
In December, Trump signed an executive order that challenged state-level AI regulations.
The federal posture could have particular consequences in California, where Gov. Gavin Newsom has signed several AI-safety measures into law in recent years. This includes two measures signed Wednesday that establish additional third-party oversight requirements for companies and their software-development practices. The measures build on an earlier law sponsored by state Sen. Scott Wiener, D-San Francisco, that established industry guardrails.
Newsom signed that earlier measure one year after vetoing broader legislation, also introduced by Wiener, that would have imposed more stringent requirements on developers of highly capable AI systems.
Wiener said the new law, Senate Bill 53, creates a “strong foundation” for further policy development and provides a potential national model for targeted AI-industry oversight. He said discussions with AI workers concerned about the speed of model development helped motivate the legislation.
“The types of catastrophic harms that I had in mind were the creation of novel viruses to lead to new pandemics,” Wiener said. “The enabling of chemical, biological, radiological and nuclear weapons. The cyberattacks to melt down the banking system or electric grid.”
Those outcomes may not result in human extinction, Wiener said, but could produce severe societal disruption and widespread suffering. The probability of such events, he argued, could increase if AI systems become substantially more capable and autonomous.
“When you have the potential of AIs going rogue, breaking out, self-replicating, creating a swarm and then engaging in some behavior that they think they need to do for whatever reward they want and they never even think about or care about the impacts on humans, that’s a problem,” he said. “That’s bad.”
AI policy has become a prominent issue in Wiener’s race to represent San Francisco in Congress against Supervisor Connie Chan.
Chan has also advocated for stronger restrictions on AI companies. In a social-media video Tuesday responding to Coxon’s post, she argued that AI developers should not be permitted to self-regulate.
“Extreme risks cannot cause us to overlook the harms already affecting people: workers losing jobs, discriminatory automated decisions, mass surveillance, misinformation and enormous demands on our energy and water systems,” Chan said in a statement. “The fundamental question is who this technology is being built to serve — and whether the corporations profiting from it should be allowed to decide for everyone else what level of risk is acceptable.”
Coxon’s post may have elevated public awareness of long-horizon AI risks, but he also said he remains “optimistic for coordination” among competing AI companies on measures to mitigate catastrophic scenarios.
Others are less optimistic. “We should have stopped six months ago,” Sabien said. “If we stop six months from now, it might actually be too late. If the thing turns on, it’s too late.”

The AI infrastructure boom is set to continue as per most market research firms. AI chip and compute server upgrade cycles will necessitate the continued spending of many hundreds of billions of dollars on AI compute infrastructure for the foreseeable future.
Global data center spending is set to reach US$31.6 trillion through 2050 to meet the world’s growing appetite for artificial intelligence (AI), an investment boom with no precedent in history, PricewaterhouseCoopers LLP (PwC) said in a report released on September 2, 2026. Dwarfing projects such as the railways, Internet and electrification, spending on data centers could even hit US$50 trillion over the next two-and-a-half decades if AI adoption accelerates beyond PwC’s “central scenario” forecast, the professional service/accounting firm said. For comparison, US GDP is about US$30 trillion.

With consumers, companies and governments increasingly using AI, tech giants such as Microsoft Corp and Amazon.com Inc and smaller data center providers are setting up new computing facilities across the planet at a rapid clip. The bulk of the spending would go into what fills the data centers — hardware from companies such as AI chip leader Nvidia Corp.
At least 75 projects, worth about US$130 billion combined, were blocked or delayed by local opposition during the first three months of this year, according to research group Data Center Watch.
“AI infrastructure is becoming one of the defining capital allocation challenges of the next generation,” said Clara Cutajar, global infrastructure leader at PwC Australia. “It cuts across technology, energy, real estate, supply chains, regulation and financing. This changes how infrastructure investors need to think about capital requirements, risk and returns.”
At the same time, the tech industry is trying to blunt a backlash against data centers that threatens to slow down the buildout. Protesters cite concerns about environmental impacts, resource consumption and more broadly how AI could upend employment and society. The U.S. would capture nearly half the projected data center spending, at US$15.1 trillion, PwC said.
The Asia-Pacific region would follow at US$8.2 trillion, Europe at US$5.6 trillion, the Middle East at US$1.1 trillion and Africa at US$255 billion of the cumulative capital expenditure, PwC’s inaugural Global Data Center Outlook showed.
“Railways. Electrification. The Internet. Each required enormous amounts of capital and defined an era,” the researchers said in the report. “The AI infrastructure cycle under way dwarfs all three. This one resets every four to six years — and shows no signs of ending.”
On an annual basis, global data center spending would increase from about US$800 billion this year to US$1.1 trillion in 2030 and US$1.8 trillion in 2050, PwC predicted.
China and India would drive the largest share of incremental demand, supported by large populations, rapidly expanding digital economies, and substantial headroom for AI to embed in business and consumer activity.
While global demand is strong, factors such as power availability, data sovereignty requirements and the flow of semiconductors would determine which regions capture the investments, PwC said. Power would be the foremost factor that shapes where AI infrastructure investment occurs. Indeed, much of the forecast hinges on how fast reliable electricity supply for data centers can be established, the report said. Affordable, reliable, and increasingly low-carbon electricity at scale is the hardest requirement for many markets to meet.
While the market researchers’ projection assumes a fairly open trading system where chips move freely across borders, disruptions in semiconductor supply chains could cut global investment by nearly 20 percent, they said. Meanwhile, a growing sovereignty push could redistribute, but not reduce, global investment.
“The US$31.6 trillion question isn’t whether the capital exists. It does,” the researchers said. “Nor is the question whether the demand is real. It is. The question is which regions, operators and institutions are positioned to capture it and which aren’t.”
Analysis- Where Will the Money Come From?
OpenAI and Anthropic, the two poster-children for Western frontier AI development, routinely divulge soaring annualised revenue run-rates, but these only give a vague indication as to how things are actually going.
An LLM maker that has had a particularly good month can simply multiply that monthly figure by 12, resulting in a run rate that gives the impression that sales are booming. Two Bloomberg articles from August illustrate this distortion.
The first reveals that Anthropic’s actual revenue reached $11.5 billion in Q2, up from $4.73 billion in prior quarter, giving a total of $16.23 billion for the first half.
The second cites sources claiming Anthropic’s run-rate puts it on track to turn over $65 billion this year.

Full Stack Orchestration Layer:
The pace and scale of an unprecedented data center buildout is leading to challenges across the infrastructure lifecycle. These challenges point to a need for a single accountable orchestration layer, one designed to manage the seams across the delivery stack. PwC refers to this role as a full-stack orchestrator, a delivery platform that sets the standards, manages the integrated schedule, governs risk and change, and defines how acceptance is measured across the project.
Key Takeaways:
- PwC estimates $5.1 trillion will be invested in data centers in the five years ending 2030 and around $32 trillion over the next 25 years depending on AI adoption.
- Turning that capital into usable megawatt capacity means overcoming the industry’s biggest delivery failures around power, equipment, cooling, construction, commissioning, and compute.
- A full-stack orchestrator can turn fragmented delivery into a repeatable platform by owning standards, schedules, risk, change control, and acceptance across the entire data center build.
