CoreWeave shares and bonds slide as AI debt concerns deepen

CoreWeave's push to finance more AI infrastructure has collided with investors' growing unease about its borrowing. The Nvidia-backed cloud provider is seeking insurers' capital to fund its data centre expansion, according to the Financial Times.

The funding ambition is substantial. Bloomberg Technology described a goal of securing an investment-grade credit rating and gaining access to "unlimited" funding. But the company's bonds have been trading at levels that signal much greater investor concern.

On October 14, the Financial Times reported that a CoreWeave co-founder was targeting insurers' vast pools of capital for loans to finance the buildout.

That day, CoreWeave bonds issued six months earlier fell to 81 cents on the dollar, yielding more than 15%, MarketWatch reported. Its shares also dropped 15% to $65.78 on Wednesday, their biggest one-day decline since February, according to Business Line - Home.

CEO Mike Intrator sought to reassure staff with a memo pointing to a strong backlog, World News CNA reported on October 14. The company stood by its business model and described the market as acting "irrationally," according to Business Line - Home.

The pressure continued on October 15. Shares and bonds fell again despite the CEO's assurances about the contract backlog, CNN Brasil reported. Fast Company put the stock's decline over the preceding week at more than 25%.

Also on October 15, Nvidia CEO Jensen Huang said CoreWeave was getting financially stronger, according to Bloomberg Technology. He said Nvidia did not need to backstop the company and that its cost of capital was decreasing, The Next Web reported.

The market signals remain strained. Buying protection against a CoreWeave default has become more expensive, according to MarketWatch, while CNBC reported that its credit default swaps had reached distress levels on Thursday.

That leaves a sharp divide between management's confidence and investors' pricing of risk. Intrator has stressed the backlog, and Huang has rejected the need for a backstop. Yet falling bond prices and rising default protection costs show those assurances have not settled the funding concerns.

The concrete funding issue is whether CoreWeave can turn its pursuit of insurance industry capital into loans for the buildout described by the Financial Times. The coverage does not establish that this financing has been secured.

Bond yields and default protection costs will show whether investor concern is easing. The unresolved tension is between Huang's claim that CoreWeave's cost of capital is decreasing, reported by The Next Web, and the fresh credit market pressure reported by CNBC.
