# AI Data Center Financing Tightens as 47 US Projects Stall and Anthropic Seeks a Second $45 Billion Nscale Lease

Global AI-related debt issuance fell from $113 billion in June to $23 billion in September, and Nscale, Anthropic's landlord, faces investor demands to cut its listing valuation from $30 billion to as little as $16 billion.

Funding for the American AI build-out is tightening at the developer level, even as demand from the largest model labs keeps growing. On October 18 the Financial Times reported that [at least 47 large US data center projects were delayed, withdrawn or blocked in 2026](https://fourweekmba.com/ai-47-stalled-projects-and-a-microsoft-exit-ais-local-limits/), citing data from the regulatory-intelligence company RegLayer. RegLayer called the count conservative because it covers only the largest projects. [Bernstein analysts estimated](https://coinedition.com/u-s-ai-data-center-boom-faces-debt-risks-as-costs-rise-and-projects-stall/) that only about 35% of the planned US pipeline is credible. The Financial Times also counted more than 1,000 US communities that tried to impose moratoriums or other restrictions on AI infrastructure this year.

Credit is contracting along with permitting. According to Financial Times data, [global AI-related debt issuance fell to $23 billion in September from $113 billion in June](https://finance.yahoo.com/technology/ai/articles/banks-pulling-back-ais-massive-090010718.html), and banks are reducing their exposure to avoid concentration risk. In September, Bloomberg had already tallied [$68 billion of new US data center projects disrupted](https://www.bloomberg.com/news/articles/2026-09-21/new-data-centers-worth-68-billion-disrupted-in-us-data-show). Some lease contracts let AI customers withdraw if a developer misses its financing or delivery deadlines, as the [AI Post summary of the Financial Times report](https://t.me/aipost/8554) notes. That clause leaves the construction risk with the developer and its lenders, not with the tenant.

Anthropic, by contrast, is adding capacity. Bloomberg reported on October 19 that [Nscale is in advanced talks with Anthropic for a second contract of roughly $45 billion](https://www.bloomberg.com/news/newsletters/2026-10-19/nscale-anthropic-eye-45-billion-cloud-deal-as-ai-trade-rebounds) covering 460 megawatts of Nvidia Vera Rubin capacity at the Monarch campus in West Virginia. The [first deal, signed in August](https://www.cnbc.com/2026/08/26/anthropic-and-nscale-strike-45-billion-cloud-deal-sources-say.html), was a six-year, 460-megawatt lease at the same site, with delivery from late 2027. [Data Center Dynamics reports](https://www.datacenterdynamics.com/en/news/anthropic-and-nscale-in-talks-for-second-45bn-deal-report/) that Anthropic holds a right of first refusal on an expected third building. The [AI Post channel](https://t.me/aipost/8550) noted that the talks began less than two months after the first contract.

Nscale, the landlord in these deals, carries the most financial risk. The company filed for a New York Stock Exchange listing under the ticker NSCL and seeks to raise up to $3 billion. Investors are [pushing back on its roughly $30 billion valuation target](https://news.bloomberglaw.com/securities-law/ai-cloud-firm-nscale-faces-investor-pushback-over-ipo-valuation), and some have told bankers that $16 billion to $19 billion would attract more buyers. [The Next Web reports](https://thenextweb.com/news/nscale-ipo-valuation-investor-pushback) that Microsoft, which is both an investor and a client, withdrew from a UK data center deal after power constraints delayed the site. Construction at Nscale's flagship facility in Norway is six months behind schedule, and the Australian developer Firmus recently failed to complete its initial public offering. Nscale disclosed $103.4 billion of active and contracted total contract value as of August 31. Agreements with Anthropic account for up to about $44.6 billion of that figure.

## What this means

Demand for compute is holding up. The shortfall lies in the financing and permitting needed to turn that demand into delivered megawatts. Labs that generate large revenue, such as Anthropic, now have more negotiating leverage. They sign long leases that include exit clauses, while debt-funded developers like Nscale and Firmus carry the risk of construction, power hookups and refinancing. The common reading of this as "an AI bubble bursting" misses the point. Top-tier demand is still rising (Anthropic is doubling its order), so the strain falls on weakly capitalized middlemen and their lenders. Neocloud equity, private-credit exposure to data centers, and suppliers whose order books depend on second-tier developers are exposed. Hyperscalers with strong balance sheets, and Nvidia through its concentrated large customers, are less exposed. The closest precedent is the 2000 to 2002 telecom fiber overbuild. Debt-funded carriers such as Global Crossing failed, and the fiber they laid was later used at lower cost by better-capitalized owners. The likelier outcome is that Nscale either prices well below $30 billion or delays its listing within weeks to a few months. Over the next two quarters, more capacity would then be financed through customer prepayments and hyperscaler balance sheets rather than standalone project debt. That read depends on Anthropic's revenue continuing to justify its commitments. It would be proven wrong if AI-related debt issuance in October and November recovers toward June's $113 billion and Nscale lists near its original target. This supports the desk's thesis that compute is becoming a strategic currency, because scarce delivered capacity is going to whoever can pay for it.

## What to watch

- The price and timing of Nscale's listing. A deal near $16 billion to $19 billion would set a lower valuation benchmark for every other neocloud planning to go public.
- Monthly AI-related debt issuance for October. A second month near September's $23 billion would confirm that lenders have pulled back, not merely paused over the summer.
- Whether Anthropic signs the second Monarch contract and exercises its option on the third building. That would show labs locking in capacity while their landlords struggle to fund it.
- New local moratoriums and utility interconnection rulings in the states with the largest planned pipelines, because permitting, not chips, now decides which projects get built.
