CoreWeave's weighted average cost of debt declined to 7.9% by the end of the third quarter, a reduction of 250 basis points compared to the previous year, a CoreWeave executive said. The executive emphasized that the AI cloud infrastructure provider would avoid the unsecured debt market at current yields, citing no necessity for that type of financing.

The cost reduction comes amid CoreWeave's significant debt-funded expansion, which increased the company's total debt to approximately $46.9 billion as of September 30, 2026. The company's reliance on secured loans and convertible bonds appears to be a strategic move to keep its borrowing costs effectively managed while it scales.

Debt-Funded Growth at Scale

CoreWeave operates large-scale GPU cloud infrastructure used to serve artificial intelligence workloads. Founded in 2017 as a cryptocurrency mining venture, the company later shifted its focus to AI cloud computing and went public on the Nasdaq in March 2025 under the ticker CRWV. Its customer base includes major technology companies and AI developers such as Microsoft and OpenAI, while chipmaker Nvidia is both a key supplier of GPUs and an investor in the company. Financing that buildout has required substantial borrowing, making the trajectory of the company's debt costs a central element in assessing its financial position.

The financing routes themselves help explain the executive's stance. Unsecured debt is issued without collateral backing and is priced at whatever yield the market demands, while secured loans are tied to assets and convertible bonds carry equity-linked terms that typically reduce the coupon required from the borrower. By staying out of the unsecured market at prevailing yields and leaning on those alternatives, CoreWeave has lowered its weighted average borrowing cost year over year even as its total debt balance has grown to roughly $46.9 billion.

The reduction in CoreWeave's cost of debt appears consistent with improved financial stability, suggesting reduced bankruptcy risk. The company's decision to avoid the unsecured debt market at prevailing yields indicates a preference for secured loans and convertible bonds as its primary financing tools. Market pricing suggests a decrease in the likelihood of CoreWeave announcing bankruptcy by December 31, 2027.

How CoreWeave manages its debt strategy from here will be a key measure of that trajectory, particularly whether it continues to rely on secured and convertible financing to hold down costs as it scales. Its financial performance, any potential debt restructuring or refinancing, and significant changes to its major contracts or partnerships — including those with customers such as Microsoft and OpenAI and with supplier and investor Nvidia — are the developments most likely to shape the market's perception of its financial health.
