CoreWeave, a New Jersey-based provider of generative AI infrastructure, software, and cloud services, has seen its five-year credit default swap (CDS) spreads consistently trade above 800 basis points. This elevated level for CDS, which are financial derivatives acting as insurance against a borrower’s debt default, suggests a market-implied probability of default between 40% and 47% over the next five years. In late July 2026, CoreWeave’s CDS even approached 1000 basis points, implying a roughly 50% probability of default over five years.

This market sentiment stands in contrast to S&P Global Ratings’ B+ issuer credit rating for CoreWeave, which was affirmed on April 9, 2026, with a positive outlook. A B+ rating typically indicates a default likelihood of about 15% over five years. The discrepancy highlights a divergence between credit rating agency assessments and the market’s perception of risk.

The company’s rapid expansion, driven by high demand for AI infrastructure, has also led to substantial capital expenditures and a significant debt load, reported at $14 billion in December 2025. CoreWeave’s business model relies heavily on capital-intensive GPU purchases and data center leases, with potential vulnerabilities to rising data center rents and client pricing pressures.

S&P noted in April 2026 that CoreWeave’s revenue increased 168% to $5.13 billion in 2025, anchored by multi-year contracts. However, the company faces execution risks related to delivering contracted capacity and has experienced substantial free cash flow deficits. In August 2026, CoreWeave reported second-quarter revenue up over 200% year-over-year, with a backlog estimated at $104 billion. Despite this growth, concerns persist regarding customer concentration and the complex relationship with Nvidia, which serves as a supplier, customer, and shareholder.
