CoreWeave Bond Yield Tops 16% as AI's Credit Card Gets Costlier

The CoreWeave bond yield climbed above 16% on its 2032 notes, which carry a 9.625% coupon, CNBC reported on November 6. The price of insuring CoreWeave's debt against default also passed its October peak on Thursday. This matters beyond one company: CoreWeave is a bellwether for debt-funded AI data centers, and default insurance costs are now rising at far stronger borrowers, including Nvidia and Amazon.

CoreWeave's default insurance spiked, then eased a little

CoreWeave's five-year credit default swaps rose above 1,289 basis points on Thursday, wider than their October peak, according to Deutsche Bank data cited by CNBC. They eased 8% on Friday to around 1,155. A spread of 1,155 basis points equals 11.55 percentage points a year.

The direction is clear from recent readings. Earlier this week, 24/7 Wall St., citing Reuters, described CoreWeave's April-issued bonds as yielding around 15%, with default insurance implying a nearly 63% chance of default within five years. That is a market price, not a forecast from any rating agency. A yield in the secondary market also does not change the interest on bonds already sold, but it signals what new borrowing could cost.

The stock has moved with the bonds. CoreWeave fell 9.8% to $43.66 on Thursday, 24/7 Wall St. reported, during the AI stock crash that pushed the Nasdaq into correction. It bounced on Friday and was up 5.8% with an hour of trading left, AP reported. Even so, the shares had roughly halved over the prior month, according to 24/7 Wall St.

Interest costs are the number CoreWeave has to outrun

CoreWeave's total debt reached $51.6 billion at the end of the second quarter, and capital lease obligations added another $16.54 billion, 24/7 Wall St. reported. Interest expense was $640 million in that quarter. For the third quarter the company guided to $860 million to $940 million of interest, against adjusted operating income of $200 million to $260 million. Interest is expected to be at least three times that operating profit measure.

The case for the company rests on contracted demand. Revenue backlog stood at $104.2 billion at the end of June, not counting more than $25 billion of commitments signed early in the third quarter. Nvidia has also agreed to buy any unsold CoreWeave capacity through April 13, 2032, according to 24/7 Wall St. Chief executive Michael Intrator said in August that moratoriums would affect where data centers go rather than demand, the same outlet reported.

Credit stress is spreading to the strongest borrowers

The bigger change this month is who else is being repriced. Default swaps on Nvidia rose 76% in a month, Broadcom's 49% and Amazon's 44%, CNBC reported. The absolute levels remain low, which is the important caveat: Nvidia's spread is about 139 basis points and Oracle's about 298, against roughly 1,100 for CoreWeave.

One lender is also looking to sell. ING is seeking bids on a dozen data center loans worth about $500 million, including a $25 million piece tied to the Stargate site in New Mexico, Bloomberg reported, according to Reuters and CNBC. Bids of at least $10 million are due November 19. ING declined to comment, and no report ties CoreWeave to those loans. Hedge funds have been selling AI debt as well.

How much more debt the AI build-out still needs

The supply ahead is large. Goldman Sachs counts five AI bond deals totaling $67 billion since October 29 and $296 billion of hyperscaler debt issuance this year, CNBC reported. It forecasts $440 billion of hyperscaler issuance next year, plus $300 billion of project-level debt. Bank of America expects AI-related credit issuance to rise 31% to $685 billion in 2027, then fall 23% to $531 billion in 2028.

Politics cuts the other way. Bank of America warned that its forecasts could prove too high if the Democratic midterm wins slow AI infrastructure projects, because fewer projects would need less debt funding. Goldman estimates that the states likely to add restrictions hold 45% of planned capacity, as we explain in our report on the data center moratorium risk. Jim Reid of Deutsche Bank noted that debt and equities are now moving more in sync.

What the AI Bubble Index says

The AI Bubble Index stood at 62.7 in its latest published reading, dated November 5, in the Normal band and down from 64.6 a week earlier. Fragility, at 70, sits above Euphoria at 63.4, and the systemic risk family reads 69.9. That reading came before Friday's partial rebound, and one day's change says little. The dashboard tracks each family daily, and our guide to AI investment risks explains why financing is one of the main exposures in this cycle.
