The insurance market gives CoreWeave a coin flip
A public market is now betting that the most visible borrower in the AI buildout is more likely to fail than not, and the hedge funds that financed the trade are already showing the losses.
Investors who insure CoreWeave's debt against the company failing to pay pushed the price of that insurance to a record on Thursday, according to ICE Data Services figures reported by Bloomberg (the five-year contract rose as much as 74.5 basis points to 1,194.5). At that price, protecting $10m of bonds costs about $1.2m a year, and the market is saying there is a better-than-60% chance the company fails to pay by 2031. CoreWeave is the company that borrowed most, and most visibly, to build the AI boom's data centers, and the open market now rates it a coin flip. Its bonds that pay 9% and come due in 2031 slipped to 82.75 cents on the dollar, which works out to a 14.5% interest rate for anyone buying today; its 9.75% bonds of the same year rose 2.25 cents to 87.75. The shares went the other way: after Wednesday's 15.5% fall they closed up about 6% after Jensen Huang, who runs Nvidia, said Nvidia 'didn't need to backstop' the company and that its cost of capital 'is actually decreasing'.
Two things are worth slowing down on. First, what set the bonds off was not bad numbers but a plan: the company's talk of raising money from life insurers against debt secured on its chips and graded safe by the rating firms. Existing bondholders heard that as new lenders arriving ahead of them in the queue, with first claim on the chips if things go wrong. That is our inference, but it is the only reading that explains bonds falling on news of more money coming in. Second, Huang's remark removes a comfort that skeptics of the circular financing had assumed was there: the supplier says it will not stand behind the customer's debt. Bill Zox of Franklin Templeton put the loop neatly: 'Debt investors are freaked out about CoreWeave's cost of equity and equity investors are freaked out about its cost of debt.'
The losses have already landed somewhere. Goldman's prime brokerage, the desk that lends to hedge funds, says global long-short funds, which bet on some shares rising and others falling, lost money every day this week, 2.9% to Wednesday. Asia-focused stock pickers are down 6.8% in the first half of October and have given back more than half of the gains that had them up over 40% at the late-June peak. For scale: from Covid to the end of 2025, Goldman's three broad fund strategies never all fell more than 0.8 percentage points (80bp) on the same day. It has now happened three times this year, the latest on Wednesday. Thursday's bounce was in the stock. The insurance price did not bounce.
