Analysis
CoreWeave shares fell 15.46% on Wednesday and slid another 5.62% after hours, after venture capitalist Chamath Palihapitiya posted a chart of the company's bond yields climbing toward 15% and asked whether the AI buildout was creating a private-credit bubble. Fortune reported that CoreWeave's 9.625% notes due 2032 touched that level intraday, and 247wallst.com noted Elon Musk's one-word reaction to the chart: "Yikes."
CoreWeave went public on Nasdaq in March 2025 as the first pure-play "neocloud," renting out Nvidia GPU clusters to AI labs instead of running a diversified cloud business like AWS or Azure. Pulse flagged the company's rising debt load back in an earlier look at AI data center financing, when CoreWeave's borrowing was already emblematic of a sector funding itself off narrow, long-duration contracts rather than diversified revenue. This week's selloff is the first time the market has priced that risk into the bonds themselves rather than just the equity.
How Much Does CoreWeave Actually Owe?
By its latest quarter, CoreWeave's balance sheet breaks down like this:
- Total debt — $35.6 billion, the bulk tied to data center buildouts.
- Operating lease liabilities — $16.3 billion, bringing combined obligations to roughly $52 billion.
- Quarterly revenue — $4.6 billion, against a $1.4 billion net loss.
- Remaining performance obligations — $103.7 billion in contracted future revenue, with 41% due by 2028.
Co-founder Brannin McBee told the Financial Times he wants to borrow even more from insurance companies, telling the paper their capital is effectively "unlimited."
CoreWeave isn't alone in leaning on debt rather than equity to fund GPU buildouts. Lambda, Crusoe and Nebius have all followed a similar playbook, and even a much larger, more diversified cloud provider felt the strain this fall: Oracle sent lender Blue Owl a force majeure notice over a New Mexico data center project after a natural-gas pipeline needed to power the site slipped nearly six months. Gartner estimates roughly 80% of today's neocloud providers will stop operating independently by 2030 — a forecast that reads very differently depending on whether you're the lender or the borrower.
Who Actually Pays If AI Demand Cools?
The bigger worry isn't the debt total, it's concentration. CoreWeave's top three customers, including Microsoft and OpenAI, generated 72% of its second-quarter revenue. Bulls like Neostellar Capital's Evan Schlossman argue the debt is sound because it's backed by take-or-pay contracts from investment-grade counterparties, and CoreWeave itself says 98% of its revenue comes from committed contracts rather than spot demand.
Critics read the same contracts differently. Accountant and Substack writer Francine McKenna argues those take-or-pay clauses are only as strong as a counterparty's willingness to honor them in a downturn, writing bluntly that "Microsoft is ruthless and will eat CoreWeave for lunch." Microsoft declined to comment to Fortune. That's the real counterweight to CoreWeave's own framing: a contract that says a customer must pay is not the same as a contract a customer can't get out of, and nobody has tested that distinction in an actual AI demand downturn yet.
Watch two things from here: whether CoreWeave discloses any change in customer concentration on its next earnings call, and whether bond spreads at Nebius, Lambda or Crusoe move in sympathy with CoreWeave's. That correlation, more than any single yield print, will show whether this is a CoreWeave-specific wobble or the first real test of AI infrastructure financing as a category.
