CoreWeave Stock Sinks on AI Debt Despite Revenue Surge

Shares in CoreWeave (CRWV) have lost more than a third of their value in October, with investors balking at the roughly $52 billion in debt the company has taken on for AI data centers, despite revenue more than doubling last quarter.

Despite Nvidia's backing, CoreWeave did not begin in AI. Formed in 2017 as Atlantic Crypto, it mined Ethereum (ETH) on graphics processing units (GPUs), and in 2019 changed its name to CoreWeave after repurposing those machines to rent out computing capacity.

Why Bond Investors Are Turning Away Despite Strong Revenue

CoreWeave's second-quarter revenue came to roughly $2.5 billion, up 112% from a year earlier. Bond investors, however, now demand far more compensation for lending to the company. Unsecured bonds carry a yield of about 15%.

Its credit default swaps, which serve as insurance against default, now carry a spread above 11%.

Jensen Huang, Nvidia's chief executive, said last week that CoreWeave does not need a backstop from the chipmaker, and he went straight to the subject of its financing costs.

“Their cost of capital is actually decreasing.”

Huang made those remarks on Oct. 15, a day after CoreWeave stock fell 15%, its largest one-day decline since February.

What a Failed CoreWeave Refinancing Would Mean for the AI Trade

Nvidia's involvement with CoreWeave runs in three directions. It supplies the processors, owns about 9% of the company, and has promised to buy up to $6.3 billion of CoreWeave's capacity if no other customer steps forward.

The ties to crypto remain, too. CoreWeave has leased space from Core Scientific (CORZ), a bitcoin miner pivoting toward AI hosting; its shareholders blocked a $9 billion takeover by CoreWeave in October 2025.

As a group, the neoclouds — businesses that rent out GPU capacity using Nvidia hardware — are under pressure. Nebius and IREN have each slid at least 30% this month, per CNBC, and CoreWeave has fallen as well.

Should CoreWeave's refinancing prove weak, borrowing costs could be reset across every debt-backed GPU buildout, including miners like Core Scientific that are moving to AI.
