- Lead. The five-year credit default swap spread on CoreWeave, the AI cloud company that rents GPU capacity to OpenAI and other large AI developers, surged above 1,140 basis points this week before easing to about 1,088 bps—a level that ICE Data Services pricing implies carries a roughly 60% probability of default over five years.
- Fact. The yield on CoreWeave’s 9.75% bond due 2031 hit 15.78%, and the company carries more than $51 billion in total debt and financial obligations accumulated to buy Nvidia chips and build data centres.
- Stake. Credit stress at CoreWeave, combined with a hot US CPI reading, erased more than $1 trillion in combined market value from 20 of the world’s largest AI and semiconductor stocks in the same week, raising questions about whether the financing model behind the AI infrastructure build-out can hold at current scale.
The Trigger: OpenAI Revenue Concerns
CoreWeave’s credit stress accelerated on October 8, when a report circulated that OpenAI’s annualised revenue had come in below figures used in earlier financing discussions. OpenAI is one of CoreWeave’s largest customers and provides a significant portion of the contracted backlog CoreWeave relies on to service its debt. The report sent CoreWeave shares down 15.5% in a single session.
The five-year CDS spread, which had already risen 177% over the prior twelve months, jumped a further 33% in one week, according to CNBC’s reporting. At the peak, the spread briefly exceeded 1,140 basis points before easing to approximately 1,088 bps. The CDS level, when run through ICE Data Services pricing models, implies a roughly 60% probability of default over five years, compared with approximately 30% a year ago. Shares partially recovered on Thursday, gaining 5.94%.
The Debt Architecture
CoreWeave has taken on more than $51 billion in debt and financial obligations, with the money going primarily to purchase Nvidia chips and build data centre infrastructure its cloud customers require. That model depends on long-term customer contracts generating cash flows sufficient to service the debt. CEO Mike Intrator pointed to the company’s backlog of more than $100 billion, roughly two-thirds of which is tied to investment-grade counterparties, as evidence the obligations are manageable. Deutsche Bank also cited the backlog in a note defending the company’s credit position.
Analysts have drawn a distinction between long-run demand for AI services—which remains robust—and near-term cash flow needed to support current debt service levels. The concern is not that AI services will disappear but that revenue ramps may be slower than the debt schedule requires, particularly if large customers like OpenAI grow more slowly than earlier projections assumed.
The Wider Market Effect
The CoreWeave dislocation did not remain contained. Combined with a hotter-than-expected US CPI print, credit stress at the company helped erase more than $1 trillion in combined market value from 20 of the world’s largest AI and semiconductor stocks over the week. Nvidia fell 1.84%, AMD dropped 1.5% and Intel lost about 2.8%. Capital rotated into Treasuries, pharmaceuticals and materials.
The episode connects to a broader pattern of AI valuation scepticism that has built through the autumn. Earlier in October, Nvidia-backed Firmus scrapped a $5 billion IPO after investors refused to accept a 600x revenue multiple, suggesting the market’s tolerance for AI valuations at any price had been narrowing even before CoreWeave’s credit moved into distress territory.
