CoreWeave credit default swaps hit 1,038 basis points, a level S&P calls distress

CoreWeave shares closed 5.94% higher on Thursday after Wednesday's 15.5% drop, but the market for its debt did not recover, CNBC reported. The yield to maturity on its 9.75% notes due 2031 reached 15.78%, up from about 14.9% a day earlier in our Wednesday report. The cost of insuring the debt rose too.

What the swap spread says

A credit default swap is insurance against a borrower failing to pay. CNBC said the spread on CoreWeave's five-year contracts topped 1,140 basis points at one point and last stood near 1,038, up 16% in a week and 164% from a year ago. Gavan Nolan of S&P Global Market Intelligence told CNBC that 1,000 basis points or more is generally a sign of credit distress.

The arithmetic: 1,038 basis points is 10.38% a year, so protecting $10 million of CoreWeave debt costs roughly $1.04 million annually. For comparison, CNBC put Oracle's five-year spread at 282 basis points, about $282,000 a year per $10 million. The two are not the same risk. Oracle is rated BBB, and Jim Reid of Deutsche Bank warned that a downgrade could force investment-grade-only holders to sell.

The number behind the number

CoreWeave's 10-Q for the quarter ended June 30 shows why cash flow is the question. Revenue was $2,575 million, up from $1,212 million a year earlier. Interest expense, net, was $640 million, up from $267 million, and the pre-tax loss was $564 million. Interest was about 25 cents of every revenue dollar. Our Wednesday piece used a narrower $558 million debt-interest figure; the income statement line is the broader one and includes imputed interest on finance leases and revenue agreements, net of capitalized interest.

Demand is not the doubt. Nolan told CNBC no one is questioning that the contracts are real; the question is whether the cash arrives. CEO Mike Intrator told staff the market was acting "irrationally" and that the backlog "more than supports all of our debt obligations." Deutsche Bank said about two-thirds of a backlog above $100 billion sits with investment-grade customers including Microsoft, Meta, IBM and Caterpillar.

Who it hits

Directly: holders of CoreWeave's notes and the lenders to data-center developers that depend on neocloud tenants. Indirectly: any company whose financing is priced off the same appetite for leveraged AI debt. CNBC reported that Micron and AMD were also pressured by a sell-off in South Korean chip stocks, though Micron closed up 1.87%.

For an ordinary business borrower the lesson is narrow. Spreads on one distressed name do not reprice a bank line of credit. They are a gauge of how nervous lenders are about debt that depends on future cash flow, which is the same test a small-business lender applies to any applicant.
