CoreWeave was supposed to be the picks-and-shovels play of the AI boom. Right now it looks like the canary in the coal mine.
The stock closed Thursday at $55.60, down about 10% on the day and a fresh 52-week low, according to Seeking Alpha. It fell 15.5% last Wednesday alone, per CNBC. Whether this is panic or prophecy is the question.
The Debt Pile
CoreWeave has roughly $51.6 billion in total debt, CNBC reports. In the second quarter it lost $626 million on $2.58 billion in revenue, and its interest expense hit $640 million, up from $267 million a year earlier, per the company's earnings presentation. It posted an operating loss that quarter, so the interest bill outran operating profit.
And the spending isn't slowing. CoreWeave guided to $35 billion to $39 billion in capital expenditures this year. S&P Global Market Intelligence's Gavan Nolan told CNBC it has "capital expenditure levels that are almost hyperscaler-like, but it doesn't have the hyperscaler balance sheet."
The Market Is Flashing Red
CNBC reports yields on CoreWeave's bonds have jumped to nearly 15% to 16%. Its five-year credit default swaps passed 1,000 basis points, a level Nolan says generally signals credit distress. Reuters, citing LSEG data, reported that level implies a nearly 63% chance of default over five years.
The market is "basically saying 'no mas' to AI debt without operating cash flow support," Evercore ISI's trading desk said, per CNBC.
Concentration and Circular Deals
Reuters reports Microsoft made up about 67% of CoreWeave's 2025 revenue, citing company filings. OpenAI has signed contracts worth about $22.4 billion in total, Reuters reports, and Nvidia holds roughly 10%, according to the Globe and Mail. Nvidia has also agreed to buy CoreWeave's unsold capacity through 2032.
That web worries some investors. Reuters says they're focused on "circular financing" between chipmakers and customers. Marlborough's James Athey told Reuters the problem is "huge interconnectedness," with the same assets held "in the same portfolios, by the same types of investors," and he warned that leverage makes it worse.
What Analysts Warn
Gartner's John Lovelock says neocloud revenue won't clear an 18% return hurdle until 2032. Gartner expects more than 80% of neoclouds to cease independent operations by 2030. He later told CNBC that means consolidation, not necessarily bankruptcy.
Gimme Credit's Saurav Sen warned the selloff "risks becoming a self-fulfilling prophecy." Deutsche Bank's Jim Reid said it could trigger "broader issues in other AI-related names," and Oracle's default swaps have already widened. Hedge fund manager Alberto Gallo said CoreWeave will "need a capital injection or a bailout." His firm holds bets against its bonds.
Short seller Kerrisdale Capital called it a "heavily levered GPU rental scheme" back in 2025.
The Other Side
CEO Mike Intrator told staff the market "misunderstands and acts irrationally," saying the backlog "more than supports all of our debt obligations." That backlog was $104.2 billion at the end of June. Nvidia's Jensen Huang said "CoreWeave's financial strength is improving every day." Janus Henderson's John Lloyd, who owns the bonds, called the selloff "a little bit of overreacting."
Our Take
Nobody is saying demand is fake. Nolan told CNBC the question is whether the cash flows arrive. If they don't, analysts warn the pain won't stop at one company. CoreWeave reports earnings in November, and everyone will be watching.
