CoreWeave shares fell roughly 15% Wednesday as yields on the AI infrastructure company’s debt climbed to about 15%, intensifying scrutiny of its borrowing costs. CNBC reported that the Nvidia-backed company’s stock was down 14.98% at 1:16 p.m. ET, while a post highlighting the bond yield drew a one-word response from Elon Musk: “yikes.”
The market moves are not themselves proof of a default. They show that investors are demanding a much higher return to hold the debt. Barron’s described the bond selloff as evidence of credit investors’ concern about CoreWeave’s debt burden and future borrowing costs.
Credit concerns move into the spotlight
The selloff gained attention after Social Capital founder Chamath Palihapitiya posted a screenshot of CoreWeave bonds yielding 15%, according to CNBC. Musk’s reply amplified the discussion, but the underlying concern came from the credit market: higher yields make future borrowing more expensive and signal that investors see greater risk.
DA Davidson analyst Gil Luria made the case more bluntly in comments quoted by a market-focused X account. He compared CoreWeave’s model to borrowing at 9% to buy Treasuries yielding 5%, calling it value destruction and warning the company could be wiped out if conditions deteriorate. That is an analyst’s assessment, not a declaration from CoreWeave or proof of an imminent default.
Options traders prepare for more volatility
Bearish trading accelerated alongside the stock decline. CNBC reported that CoreWeave options volume rose to more than seven times its 30-day average, with traders buying nearly 200,000 puts compared with 106,000 calls. One new position involved 26,000 put contracts expiring December 18 with a $37.50 strike price, a trade that would require another 42% drop over two months to pay off.
CoreWeave was also caught in a broader retreat from rate-sensitive AI stocks. Reuters reported that CoreWeave and fellow neocloud provider Nebius were each down more than 11% at 12:30 p.m. ET, while Oracle, Dell and HP also fell. Reuters said the inflation surprise increased rate-hike expectations, pressuring AI-buildout beneficiaries that are sensitive to higher borrowing costs.
