CoreWeave (CWVG) Stock Drops 35% Amid Rising Bond Yields and AI Concerns

CoreWeave's (CWVG) stock price fell 35% in October, pressured by rising bond yields and investor concerns about AI infrastructure costs. The company's market capitalization has declined from a peak of $90 billion in mid-2025 to roughly $31 billion now. Its unsecured debt yields about 15%, reflecting credit market caution.

Credit default swap spreads for CoreWeave's five-year debt increased 171% over the past year and rose 36% in October alone, reaching 1,115 basis points (11.15%). The spike signals heightened perceived risk among bond investors. Other neocloud companies face similar declines, with Nebius down 32% and IREN down 39% this month. Australian firm NextDC cut its earnings forecast leading to a 40% share drop, while Firmus canceled its IPO citing market volatility.

CoreWeave is closely tied to the U.S. AI market, with Nvidia holding a 9% stake and Microsoft contributing over two-thirds of 2025 revenue. The company has $20.7 billion in debt maturing through 2030 plus $14.9 billion thereafter, raising concerns about refinancing at higher rates. Investors are waiting for regulatory clarity post-U.S. midterm elections before engaging in high-yield debt financing.

This matters to investors because CoreWeave's heavy debt load, rising financing costs, and regulatory uncertainties increase the risk profile of its shares and bonds. The 15% unsecured debt yield and rapidly rising credit default swap spreads quantify the market’s concerns about CoreWeave's financial health and growth prospects amid AI sector volatility.
