CoreWeave Bond Yield Tops 16% as AI Infrastructure Debt Costs Alarm Credit Markets

CoreWeave's bond yield has climbed above 16%, a fresh high that underscores deepening investor anxiety about the cost of financing the artificial intelligence infrastructure boom. The neocloud company, which operates more than 51 data centers and carries over $51 billion in debt and obligations, has seen the yield to maturity on its 9.625% bond due in 2032 surge as credit markets grow less forgiving of capital-intensive AI businesses. CNBC framed the dynamic as the AI sector's "credit card" growing costlier, a reference to the heavy borrowing that has funded rapid GPU fleet expansion.

The stress has spread beyond CoreWeave. Default protection costs, measured through credit default swaps, have risen across a range of AI-linked companies including Nvidia, Broadcom, and Oracle, signaling that credit investors remain cautious even as equity markets have at times rebounded.
