CoreWeave, the AI cloud company that rents Nvidia chips to OpenAI, Meta and the rest of the model makers, called its third quarter “a breakout quarter.” Revenue rose 168% to $3.66 billion, beating forecasts, and the company raised its full-year outlook to $13.0 billion to $13.3 billion. The stock helped pull Nasdaq futures up about 2% on Wednesday. Then you get to the line under operating income.
Here is the quarter from CoreWeave’s own release to the SEC, with a column we added:
| Q3, in millions | 2025 | 2026 | Change |
|---|---|---|---|
| Revenue | $1,365 | $3,661 | up 168% |
| Operating income | $52 | $207 | up 298% |
| Interest expense, net | $310 | $846 | up 173% |
| Net loss | $110 | $709 | 6.4 times larger |
| Spending on equipment | $3,279 | $9,441 | up 188% |
The interest bill grew faster than the revenue. For every dollar CoreWeave earned running data centers, it paid about $4.09 to its lenders. It spent $2.58 on new equipment for every dollar of revenue it brought in. Wall Street is cheering the top line of a business whose net loss grew more than six-fold.
The Loan Is the Product
None of this is a secret. It is the plan. CoreWeave borrows against long contracts to build capacity before its customers need it. Its revenue backlog reached about $132.5 billion. It expects to spend $37 billion to $39 billion on capital equipment this year, and it has guided fourth-quarter interest expense to $1.05 billion to $1.15 billion. Our sum of the balance sheet puts total debt near $47 billion.
The question is who carries the risk if the backlog arrives slower than the bills. We have watched this movie once already this fall, when Oracle’s cost to insure its debt hit a record as banks struggled to sell its data center loans. And the backlog is only as good as the customers’ ability to pay. Anthropic disclosed $900.9 billion in compute commitments this week, most of it owed between now and 2045. The whole AI build-out is now one stack of promises leaning on the next.
Our view: CoreWeave is a well-run bet on a single assumption, that demand for AI compute keeps outrunning supply long enough to pay off nearly $47 billion in debt. Investors bidding the stock up on revenue growth are pricing that assumption as a fact. It is the one number the company cannot report.
