Stop saying half of 2026 US datacenter capacity is canceled

In an era where financial markets react to headlines about AI infrastructure bottlenecks, a new analysis cuts through the noise with a starkly different conclusion: the widely cited claim that half of America's 2026 datacenter capacity is canceled is not just wrong, it is a statistical artifact. Dylan Patel, writing for SemiAnalysis, dismantles the narrative by contrasting vague, AI-generated forecasts against a proprietary model built on satellite imagery and granular construction tracking. For investors and industry observers who cannot afford to be misled by "vibe-coded" data, this piece offers a necessary correction based on physical reality rather than press release optimism.

The Illusion of the 50% Cancellation

The core of Patel's argument targets the methodology behind the alarming headlines. He traces the origin of the "half canceled" statistic to a Bloomberg report that relied on data from Sightline Climate, which he argues fundamentally misunderstands the pipeline. "We find these claims quite amusing," Patel writes, noting that while other outlets amplified the story, his team's internal forecast for 2026 North American hyperscaler self-build capacity has shifted by only about one percent over the last six months.

This discrepancy, Patel contends, stems from how different models define "capacity." The flawed models treat every public announcement as a guaranteed delivery date. In contrast, Patel's approach filters out speculative projects that lack financing or interconnection studies. He argues that the headline number is built on a "hugely flawed denominator, off by multiples," because it counts early-stage, unproven megaprojects alongside shovel-ready sites.

"Claude Code pulls press releases, views unfounded GW-scale announcements as ground truth, misunderstands construction timelines and grid complexities, and compiles a terribly inaccurate report."

Patel's critique of automated forecasting tools is particularly sharp. He suggests that the rise of AI-generated analysis has led to a market flooded with confident but baseless predictions. While this framing effectively highlights the danger of relying on surface-level data, critics might argue that dismissing all non-proprietary models as "Claude Coded" risks overlooking legitimate concerns about supply chain fragility that independent analysts have raised regarding Chinese electrical components.

The Anatomy of Real Delays

Patel does not deny that delays are happening; rather, he insists they are being mischaracterized. He categorizes real setbacks into three buckets: aggressive announcements by new players, overly optimistic construction timelines, and permitting hurdles. To illustrate the difference between a "canceled" project and one simply delayed, he points to specific case studies where physical evidence contradicts public claims.

Take the Nebius flagship campus in New Jersey, developed by DataOne. The developer initially targeted a four-month delivery for its first phase, a timeline Patel deemed unrealistic from the start. "Satellite imagery shows the shell going up remarkably fast, but setting up the MEP took far longer than the shell itself," he notes, pointing out that while the building structure was visible quickly, critical cooling equipment lagged significantly behind schedule.

Similarly, he examines Core Scientific's Denton campus, where a combination of weather, construction issues, and even an exploding transformer pushed timelines back. However, Patel emphasizes that his model successfully predicted these specific slippages while maintaining that the broader industry pipeline remains robust. "Our datacenter Model flagged the STACK Infrastructure / Oracle permitting impasse months before Bloom Energy stepped in," he writes, highlighting the predictive power of tracking regulatory hurdles rather than just construction milestones.

"The '50% cancelled or delayed' figure isn't really a statement about the US datacenter pipeline, but rather about the slice of the pipeline most prone to slipping."

This distinction is crucial for understanding the current market dynamic. The projects that are failing are often those announced by inexperienced developers with no track record, not the core infrastructure being built by established hyperscalers. As Patel puts it, "When we see a brand-new announcement in 2025 saying 2026 operational from a new 'unknown' developer, it should raise some red flags." This focus on developer experience adds necessary nuance to the conversation about capacity constraints.

The Grid and the Pipeline Reality

While Patel successfully debunks the "cancellation" myth, he acknowledges that structural bottlenecks are real. He points to the STACK Infrastructure/Oracle site, which has been pushed to 2029 not because of a lack of demand, but due to a "lack of gas pipeline and the ensuing burdensome regulation." This aligns with broader findings from related deep dives into PJM Interconnection, where the interconnection queue is clogged with over a terawatt of speculative load requests.

Patel argues that the market is currently suffering from an oversupply of early-stage projects that were never viable for 2026 delivery. "In December 2025, we flagged that over half a Terawatt is in the large load queue in the US," he writes, noting that these speculative announcements create a false sense of urgency and scarcity.

"We do not put low probability datacenters in our datacenter timelines."

This rigorous filtering process explains why his numbers remain stable while others fluctuate wildly. By excluding projects without financing or equipment orders, his model reflects the actual physical reality on the ground rather than the marketing aspirations of developers. However, this approach may underestimate the speed at which new entrants could eventually mobilize if capital conditions improve, a factor that remains uncertain.

Bottom Line

Dylan Patel's analysis provides a vital corrective to the panic-driven narrative surrounding AI infrastructure, grounding the debate in satellite imagery and construction logistics rather than press releases. His strongest contribution is exposing how automated models and media amplification have distorted the perception of risk by counting speculative announcements as guaranteed capacity. The most significant vulnerability in his argument lies in its potential underestimation of how quickly regulatory hurdles could compound across the entire industry, not just for new entrants, potentially creating a broader slowdown than even his conservative model predicts.

  • PJM Interconnection

    The article attributes major datacenter delays to grid complexities and permitting impasses rather than equipment shortages, a bottleneck formally defined by the interconnection queue process where projects wait years for transmission access.

  • Pipeline

    Specifically explaining why the STACK Infrastructure/Oracle site was delayed until 2029, this concept details how physical constraints in fuel delivery infrastructure can halt hyperscale construction even when power purchase agreements are signed.

  • Utility pole

    The article critiques 'vibe-coded' forecasts that ignore regulatory realities; understanding this specific utility mechanism reveals why local grid operators often block or delay new high-voltage connections for datacenters despite federal enthusiasm.

Stop saying half of 2026 US datacenter capacity is canceled

The claim that half of 2026 US datacenter capacity will be delayed or canceled has been circulating widely across financial and social media. This traces back to Bloomberg’s April 1, 2026 piece, America’s AI Build-Out Hinges on Chinese Electrical Parts, which framed the 2026 capacity slowdown as a consequence of a fragile, China-dependent equipment supply chain. Bloomberg didn’t lead with that framing, but within days, TechRadar, Tom’s Hardware, The Register, and other news outlets ran sharper, more clickbait versions claiming half of datacenters are cancelled, and that’s the version now circulating.

We find these claims quite amusing. We’ve consistently been first to call-out high-profile delays, like Core Scientific ahead of Coreweave’s Q3’25 earnings in our industry leading datacenter tracking model. We update the dataset by reviewing every site dozens of times a year. However, over the last 6 months, our YE2026 NA Hyperscaler Self-build forecast only moved by ~1%, and NA colocation <5%. What is causing the discrepancy?

In our view, the culprit is obvious: the data sources behind these claims of “50% of 2026 datacenters are delayed” are essentially uninformed vibe-coded datacenter forecasts that take announcements at face value, without any bit of critical judgement. We’ve seen more and more Claude Coded datacenter models and estimates crop up, all of them wrong. Thankfully, that’s not how we built our model, which is trusted for billion-dollar investment decisions by all the world’s largest tech companies in the world, as well as energy and industrials giants, and all the largest investors on Wall Street.

Claude Code pulls press releases, views unfounded GW-scale announcements as ground truth, misunderstands construction timelines and grid complexities, and compiles a terribly inaccurate report. As resident Claude Code users spending $170K+ in just one week, we are very familiar with how to use Claude, and the mistakes others are actively publishing.

Let’s be clear, delays and cancellations are occurring. Our Datacenter Model flagged the STACK Infrastructure / Oracle permitting impasse months before Bloom Energy stepped in. We caught the Nebius New Jersey delays, which are still persistent. We nailed the Core Scientific datacenter delays ahead of Coreweave’s Q3 earnings. However, we then successfully predicted Coreweave’s 1.7GW of Active Power by end of 2026 (exactly the Company’s guide) as we determined that other datacenters were on time (no, not everything is delayed!). Our data also predicted ~35B of RPO to be signed by Q1 2026 via our industry-first ...
