CoreWeave's bonds, issued only a few months earlier, tumbled to 81 cents on the dollar with yields blowing out to more than 15%, while the company's shares sank 15% on investor concern about its AI-driven borrowing binge.

Together, the developments highlight mounting unease about leverage and credit risk underpinning the AI investment boom.
