CoreWeave shares rebound 5.9% after debt fears drive a sharp selloff

CoreWeave recovered some ground on October 15, but its rebound came alongside sharp warnings from credit markets about financing the AI buildout. Shares closed up 5.9% after losing 20% over the week’s first three sessions. The loss-making cloud provider carries about $50 billion in debt, according to Reuters, putting its borrowing at the center of investor concern.

Thursday’s gain was CoreWeave’s best daily performance in more than a month. It followed a decline of more than 15% on Wednesday alone. By Friday’s premarket session, the shares had surrendered some of that recovery, Bloomberg reported, leaving the rebound short of a clean reversal of the week’s selling.

The financing behind the facilities

CoreWeave funds data-center construction by issuing bonds and relies heavily on high-yield debt. Rising Treasury yields and stubborn inflation have made that financing more expensive, Bloomberg reported. That exposure puts the cost of building computing capacity under scrutiny alongside the demand for the services those facilities will eventually provide.

Its bonds fell to levels typically associated with distress. On Thursday morning, the cost of protecting CoreWeave bonds against default reached an intraday record. Credit-default swaps, contracts providing that protection, priced in a greater than 60% chance of default within five years. That figure reflects market pricing, not a default that has occurred.

The pressure spread beyond one borrower. Reuters linked CoreWeave’s slump to a global selloff in AI stocks and doubts about whether future revenue can match spending. Bloomberg reported that the Philadelphia semiconductor index had fallen 7.9% that week, while server makers Dell and Hewlett Packard Enterprise had dropped about 20%.

Huang rejects the bailout premise

Nvidia Chief Executive Jensen Huang offered a different assessment as the shares recovered Thursday afternoon. Nvidia is both a CoreWeave shareholder and supplier. Bloomberg Intelligence analyst Robert Schiffman had identified that relationship as a possible source of capital if CoreWeave’s access to financing markets tightened. Huang said a bailout was unnecessary.

CoreWeave's strength is improving every day.

Huang also said CoreWeave’s cost of capital was decreasing. His company-specific assessment contrasted with the broader concern about rising financing costs. Separately, CoreWeave co-founder Brannin McBee told the Financial Times on Wednesday that the company’s goal was to keep winning high-grade credit ratings, according to Bloomberg’s account of the interview.

The bullish case still requires more capital

Deutsche Bank analyst Brad Zelnick called the selloff a buying opportunity and retained his buy rating. He cited CoreWeave’s customers, execution record, conversion of contracted business into revenue and infrastructure performance. Zelnick acknowledged that more capital would be needed, but argued it could be raised steadily, supported by a strong backlog of customer commitments.

Roundhill Financial strategist Thomas DiFazio likewise pointed to demand for AI computing continuing to exceed supply. Yet he cautioned that it was too early to declare an all-clear. His assessment separates the long-term appetite for computing from the immediate volatility facing investors, rather than treating this week’s selling as proof that demand has collapsed.

State Street Investment Management’s Matt Bartolini also remained positive about demand. But he said higher rates change the calculation for continued borrowing and make credible future growth essential to meeting financing costs. His argument was not that interest rates would halt the AI investment cycle, but that they alter the terms on which it can continue.
