Shares of data center operator CoreWeave plummeted over 15% on Wednesday, marking its third-largest single-day drop and nearing an all-time low, under the dual pressure of unexpectedly hot inflation data and rising U.S. Treasury yields. Concurrently, the yield on the company's 2032 bonds surged past 15%, officially entering distressed territory, with prices falling below 80 cents and the spread over Treasuries exceeding the 1000 basis point default warning threshold. This plunge wiped out approximately $80 billion in combined market capitalization from several AI infrastructure stocks, including CoreWeave, in a single day. The U.S. 30-year Treasury yield briefly climbed to 5.63% during intraday trading, suddenly bringing to light the hidden risks of financing costs for capital-intensive AI companies.
