Credit stress is SKYROCKETING among US AI companies: CoreWeave, $CRWV, 5-year credit default swap (CDS) spread surged +135 basis points on Wednesday, to a record ~1,118 basis points, implying a 63% probability of default within 5 years. At the same time, the company's 2032 bonds have fallen to ~78 cents on the dollar, yielding more than 15%, while its shares plunged as much as -17%, to near their lowest level since May 2025. $CRWV CDS has now surged over 500 basis points since November 2025. Meanwhile, Oracle, $ORCL, 5-year CDS widened to a record 288 basis points, up from 260 bps a week earlier. Default insurance costs have also risen to record highs for Amazon, $AMZN, Alphabet, $GOOGL, Meta, $META, and Nvidia, $NVDA. The pressure is intensifying as higher-than-expected US inflation raises the prospect of further Fed rate hikes. Furthermore, record AI-related borrowing is colliding with surging concerns about whether massive data-center and chip investments will generate sufficient returns. Investors are increasingly questioning the 'AI Boom'.
