The Nasdaq composite lost 4.5% last week, its worst since June, and the usual explanation is doubt about how long the AI buildout can last. The tape says otherwise. What broke was credit: the bonds and default swaps of CoreWeave, the leveraged GPU landlord, not anybody’s order book. Demand for AI computing is not the problem. The cost of financing it is, and that is a different trade with a different ending.
CoreWeave’s Own Release Shows an Interest Bill Five Times Its Operating Profit
CoreWeave’s second-quarter results release makes the case in a few lines. Revenue was $2,575 million and the backlog is about $104 billion, so customers are real. But adjusted operating income was $128 million against $640 million of net interest expense. We divided one by the other, using the company’s own figures. The adjusted number is a non-GAAP measure the company defines.
| Metric | Q2 2025 | Q2 2026 |
|---|---|---|
| Revenue | $1,212M | $2,575M |
| Adjusted operating income | $200M | $128M |
| Net interest expense | $267M | $640M |
| Operating income per $1 of interest | $0.75 | $0.20 |
| Capital spending per $1 of revenue | $2.02 | $2.49 |
A year ago operating profit covered 75 cents of every interest dollar. Now it covers 20 cents. A company that spends $6,422 million in a quarter to book $2,575 million of revenue does not live on its backlog. It lives on refinancing, which is why TheStreet reported its 2032 unsecured notes trading below 80 cents on the dollar at a yield near 14.8%, roughly 9.7 points over the 10-year Treasury’s 5.1%, though the maturities differ.
Friday’s Bloomberg Television closing-bell segment put the damage in numbers. CoreWeave “shares fell today by 12%” at 5:49, taking the weekly drop to 25%, and default swaps “priced in a more than 60% chance of default within the next five years” at 5:59.
Five Sessions Erased Nearly 30% of the Nasdaq’s Year
The Associated Press tables show the Nasdaq closing Friday at 26,140.03, down 1,226.14 points on the week and up 2,898.04 for the year. Add the week back and the index began it 4,124.18 points above where it started the year. Five sessions took 29.7% of that gain. The S&P 500 gave up 152.10 of a 966.04-point gain, or 15.7%. The Dow rose 0.7%.
CoreWeave has sat inside the Nasdaq-100 since a June rebalance, so a rerating of leveraged AI builders is a rerating of the index’s own members. We walked through the backlog-versus-debt arithmetic on Thursday.
Rates Set the Table, Credit Broke the Week
Rates matter, and the Associated Press says so. The Fed raised its key rate to about 3.9% in September, the first increase in three years, and traders now put the odds of a December hike near 76%. The 10-year topped 5.30% earlier this month, a level not seen since 2002.
Yet Bloomberg’s hosts noted the 10-year yield finished the week down about 15 basis points, after a 30 basis point swing from peak to trough. Stocks fell anyway. The hosts’ own explanation, at 7:56: “a lot of concerns, not so much just about inflation but also about some of the credit concerns around AI.”
Our read is that the price of money set the table and the willingness to lend to leveraged borrowers broke the week. The same AP report names the mechanism: tech companies that “relied on debt markets to finance an investment spree” may not be able to keep borrowing and spending. That is a financing worry, and calling it doubt about AI spending misdiagnoses it. The customer commitments are on the books. The funding is what got repriced.
Bloomberg’s hosts also argued the long-term case had not been abandoned, pointing to TSMC and ASML results. We agree with them on demand and disagree that it makes Friday a blip. If CoreWeave cannot refinance at a tolerable rate, every smaller neocloud faces the same question.
What to Watch This Week
Bloomberg’s hosts flagged Meta, Netflix, IBM and Apple among the earnings ahead. The tell is not whether capital spending guidance rises. It is how the spending is funded. A hyperscaler that says it will pay from cash flow supports the thesis that cash-rich builders beat borrowers. We think that split is the trade for now, and CoreWeave’s 2032 notes, back above 80 cents or not, are the gauge.
