America's $10tn AI build-out runs into towns, grids and lenders: at least 47 big data-centre projects stalled in 2026
What's going on? America's AI data-centre boom is starting to fray, the Financial Times reported on 18 October. At least 47 large US projects have been delayed, withdrawn or blocked so far in 2026, according to regulatory-intelligence firm RegLayer, which calls the count conservative because it only tracks the biggest sites. FT research found that more than 1,000 US communities have tried to impose moratoriums or other restrictions on AI infrastructure this year, and data-centre executives say utility regulators are refusing grid connections to projects that cannot supply their own power. Bernstein estimated this month that only about 35% of the planned US pipeline is credible.
The scale: In a paper for the Brookings Institution, Columbia Business School economist Stijn Van Nieuwerburgh projects US AI infrastructure spending of more than $10tn between 2025 and 2032, about 3.6% of GDP a year. That is roughly one and a half times the peak of 19th-century railroad building and more than three times the 1996–2003 internet build-out.
Where it is biting: London-based Nscale had 25,000 advanced chips online in August against nearly 500,000 planned, and Anthropic can walk away from its $45bn West Virginia deal if Nscale misses financing or delivery deadlines; Nscale is still targeting a New York IPO at a $35bn valuation. Nebius chief executive Arkady Volozh told a Citi conference in September that its planned 5GW would need about $250bn, of which it had financed around a fifth. SoftBank-controlled SB EnergyDealroom has a profile for this one. Try Dealroom → has yet to complete a data centre but needs about $174bn of capital to deliver some $430bn of contracted revenue, mostly from OpenAI, and has delayed a listing at a $50bn valuation. Firmus has shelved its IPO, OpenAI has pushed back its own, and several Oracle sites for the $500bn Stargate programme have slipped.
Delays are getting expensive: Cipher agreed last month to absorb the first $359mn of cost overruns at a Texas site leased to Fluidstack in exchange for more time, which required about $750mn of extra equity, partly funded by an $850mn convertible bond priced on 14 October. TeraWulf has also reworked leases for Anthropic projects. In credit markets, CoreWeave shares lost almost a quarter of their value in a week, one of its unsecured bonds slid into distressed territory, and a $1.1bn bond for a Virginia site leased to CoreWeave fell about 5% within three weeks of pricing.
What comes next: The Information reported on 18 October that data-centre and neocloud executives expect only seven to ten neoclouds to survive in a few years, out of the hundreds now trying, with consolidation possibly starting by late next year. Gartner predicted last week that more than 80% of independent neoclouds will cease to operate independently by 2030.
Facts vs. forecasts: The project count, community tally, lease amendments and market moves are reported facts. The $10tn figure is a single academic projection, while the 35% estimate and the survival forecasts are analyst and executive views. The FT tally does not say how much capacity the stalled projects represent. There are counterweights: AI labs have written contracts that protect them if partners fail to deliver, the strain so far sits mainly with debt-funded developers and neoclouds rather than the largest cloud companies, and Nvidia's Jensen Huang remains upbeat about Nscale.
Why it matters: The bottleneck in the AI build-out is moving from chips to permits, power and credit. That hands bargaining power to utilities, local councils and lenders, and turns walk-away clauses in AI labs' contracts into a central risk for builders. Two of the most exposed names are European: London's Nscale and Amsterdam-based Nebius, whose valuations rest on delivering US capacity on time.
