CoreWeave debt cost the AI data centre company $640 million in net interest in a single quarter, its own filing with the United States Securities and Exchange Commission shows. Total liabilities reached $72.0 billion as of 30 June 2026. Its shares fell 11.91% on Friday 16 October 2026.
CoreWeave, a Nasdaq-listed United States company that rents out graphics-processing capacity for artificial-intelligence work, has become the test case for how the AI build-out is being financed. The figures circulating this week have varied widely, from about $35 billion to about $52 billion. The company’s last filed balance sheet settles part of the question.
What CoreWeave’s Own Filing Shows
The clearest numbers come from CoreWeave’s second-quarter results, filed with the SEC as an 8-K on 11 August 2026 and covering the quarter ended 30 June 2026.
| Line item | Q2 2026 | Q2 2025 |
|---|---|---|
| Revenue | $2,575 million | $1,212 million |
| Net loss | $626 million | $290 million |
| Interest expense, net | $640 million | $267 million |
| Purchases of property and equipment | $6,422 million | $2,453 million |
| Total liabilities (period end) | $72,046 million | $45,967 million (31 Dec 2025) |
Two things stand out in the filed results. Net interest expense of $640 million exceeded the company’s $626 million net loss for the quarter, and it equalled about a quarter of revenue. Net interest expense also rose about 140% from the $267 million recorded a year earlier, faster than the 112% rise in revenue over the same period.
Cash and cash equivalents stood at $5,524 million at 30 June 2026, with a further $873 million of current and $507 million of non-current restricted cash. Capital spending of $6,422 million in the quarter alone exceeded that cash balance. The release also recorded a $3.1 billion syndicated delayed-draw term loan backed by high-performance computing infrastructure, and more than $10 billion raised in unsecured debt and convertible bonds, including the company’s first Eurobond issue. Our earlier report on CoreWeave’s convertible notes paying 2.875% covers one part of that programme.
Why the Debt Figures Being Quoted Differ
Coverage this week has attached three different numbers to CoreWeave, and they measure three different things. None is simply wrong.
- About $35.6 billion: debt principal outstanding at the end of June, as reported by Forbes on 15 October 2026. This counts borrowings only.
- About $52 billion: debt together with lease obligations as of 30 June 2026, a figure several outlets have cited. Data centre leases are long-term commitments that sit outside the debt principal line.
- $72.0 billion: total liabilities at 30 June 2026, the figure on the filed balance sheet. This is the widest measure and includes everything the company owes, not only borrowings and leases.
A $51 billion figure also circulated during the week. It does not correspond to a line in the filed results, and readers comparing articles should check which measure each one is using. All of these are as-of 30 June 2026 figures; the company has not published a balance sheet for the September quarter.
How the Bond Market Moved
The sharper signal this week came from CoreWeave’s debt rather than its shares. Bond yields rise when prices fall, so a rising yield means lenders are demanding more compensation to hold the paper.
- 14 October 2026: the yield to maturity on CoreWeave’s 9.625% notes due 2032 reached about 14.8%.
- 15 October 2026: the yield to maturity on its 9.75% notes due 2031 reached 15.78%, CNBC reported.
- Later in the week: Reuters, citing Tradeweb data, put the 2032 note just above 16%.
CNBC also reported that five-year credit default swaps on CoreWeave — contracts that pay out if a borrower defaults, and whose cost is quoted in basis points — widened from 368 basis points on 6 October 2026 to 643 basis points by the end of that week, and later to nearly 1,038 basis points. One hundred basis points equal one percentage point. Those levels are attributed to CNBC’s reporting and have not been confirmed by a second outlet.
Where the Market Closed on 16 October 2026
As of the close on Friday 16 October 2026 in New York, the three main United States indices finished as follows, and the Nasdaq completed its worst week since June 2026.
| Index | Close | Change on the day |
|---|---|---|
| Nasdaq Composite | 26,140.03 | −572.99 points, −2.14% |
| S&P 500 | 7,659.44 | −84.62 points, −1.09% |
| Dow Jones Industrial Average | 52,002.41 | −175.28 points, −0.34% |
CoreWeave shares closed at $61.39, down 11.91% on the day and roughly 24% across the week. The yield on the 10-year United States Treasury note held at about 5.10%. A widely watched index of chipmakers fell 3.9% on the day, its eighth consecutive decline, according to CNN. Oil traded above $100 a barrel. These are readings for one trading day and move continuously.
Pressure was not confined to CoreWeave. In his memo to staff, chief executive Michael Intrator named Firmus, AirTrunk, Lambda and Nscale as peers facing difficulties of their own. Our report on Crusoe’s funding round sets out how another operator in the same business has financed its capacity.
What CoreWeave Has Said, and What Critics Answer
Intrator sent an internal memo on 14 October 2026 calling the selloff irrational. A CoreWeave spokeswoman confirmed the memo was authentic, according to Bloomberg.
His central argument was the order book. He pointed to $104.2 billion of contracted revenue still to be recognised as of the second quarter, a figure consistent with the approximately $104 billion revenue backlog in the filed results. The company separately said more than $25 billion of net new customer commitments were added early in the third quarter.
Critics quoted in the coverage made a narrow point in reply: a backlog is contracted future revenue, not cash held, and it does not alter the timing of interest payments already due. Adam Crisafulli of Vital Knowledge told CBS News that companies of this type are funding capital spending mainly through debt and equity issuance rather than cash generated by the business.
Regulatory filings also showed Intrator sold close to $1 billion of stock. Reuters reported those sales were made mostly under prearranged trading plans, and the filings carry no indication that they were prompted by the company’s recent market difficulties.
What Is Not Yet Known
Several things that would settle the argument are not yet public.
- CoreWeave has not announced a date for its third-quarter results. Third-party trackers project a date between 5 and 16 November 2026; the company’s investor relations site is where the confirmed date will appear.
- No balance sheet has been published for the quarter ended 30 September 2026, so total liabilities and interest expense since June are unknown.
- The second-quarter release contained no full-year guidance, which the company said would be given on its earnings call.
- Kevin Warsh, the chairman of the United States Federal Reserve, gave no indication of future rate moves while in Bangkok last week. Borrowing costs for companies of this type move with those decisions.
