Nscale weighs delaying its $35 billion listing as some CoreWeave bonds yield above 16%

Nscale, a London-based company that supplies computing power to Anthropic, Microsoft and others, is considering delaying its planned $35 billion stock market listing after a sell-off^1,2. A delay would mark the latest setback for the company, which has more than $100 billion worth of contracts with customers².

The pressure extends across the sector. Yields on some CoreWeave bonds are trading above 16%, and the leading neoclouds CoreWeave and Nebius have both lost about half their value, feeding a “doom cycle” narrative in which credit risk overshadows growth³. Microsoft is pulling back from data centre deals with neocloud providers such as Nebius, IREN and Nscale that it sees as risky, and shares of Nebius and IREN fell⁵. The moves follow earlier signs that banks and investors were growing wary of AI debt⁴.

Why it matters to investors

Lenders are now stepping back. Banks that raced to fund neoclouds like CoreWeave are hesitating⁴. Nebius shelved a bond and took a one-year loan instead, having avoided CoreWeave’s debt load partly by selling stock at high prices⁴.

The risk also runs through linked borrowers. Applied Digital’s 7% notes, priced well below an earlier 9.25% coupon, rely on CoreWeave’s credit, so a CoreWeave crack would reverse that discount⁸. AI-related high-yield and investment-grade debt is also under pressure as Democrats prepare to take over Congress, in anticipation of stricter regulation of the technology, analysts and portfolio managers said⁶.

What to watch

Operating results have not settled the question. CoreWeave surprised Wall Street with better-than-expected third-quarter earnings and raised its annual forecast, yet its shares are still down nearly 40% this year⁷. The gap between growth and credit pricing is the core of the debate: the business is expanding, while bond investors demand yields above 16% on some of CoreWeave’s debt³. Nscale’s contract book of more than $100 billion has not been enough to settle the timing of its listing².

The next signals are whether Nscale goes ahead with or postpones its listing¹, whether Microsoft’s pullback extends to more providers⁵, and whether banks resume lending to the sector or leave the companies to rely on short-term loans and stock sales⁴. The political calendar matters too, as Democrats prepare to take over Congress with stricter regulation of AI in view, analysts and portfolio managers said⁶.
