An early market snapshot on October 14 put CoreWeave down 14.9% and Nebius down 9.7%, making them the Nasdaq 100's steepest decliners at that point. The figures moved with the session: CNBC later reported declines of about 16% for CoreWeave and 9% for Nebius during a broader technology selloff.
The more consequential signal came from CoreWeave's bonds. Investors were demanding much higher returns to hold the AI infrastructure company's debt, a sign that the market saw more risk in its borrowing-heavy expansion.
Why a 15% bond yield matters
CNBC reported that the yield to maturity on CoreWeave's 9.625% bond due in 2032 was 14.8%, while the yield on its 9.75% bond due in 2031 was around 14.9%. Those percentages are market yields, not changes to the bonds' fixed coupon rates. A bond's yield rises when its price falls, so the move shows buyers wanted a steeper prospective return at the prevailing price.
A chart posted by investor Chamath Palihapitiya showed the 2032 bond's yield touching 15% on October 13 before closing at 14.5%, according to Yahoo Finance. On October 14, CoreWeave's unsecured debt due in 2032 traded below 80 cents on the dollar, Bloomberg reported, citing Trace pricing data. Bloomberg described that price as a threshold widely associated with financial strain. It is a market convention, not proof that a default is imminent.
The cost of a debt-funded AI buildout
CoreWeave rents Nvidia chips to AI companies and has used debt to finance much of that hardware. Its second-quarter interest expense rose to $640 million from $267 million a year earlier, Yahoo Finance reported. The company lost $626 million in the quarter while revenue more than doubled to $2.58 billion. Total debt reached about $52 billion at the end of June, up from about $15 billion a year earlier.
The pressure was not limited to CoreWeave. CNBC reported that Oracle fell nearly 7%, Dell dropped 10%, and the Nasdaq Composite lost 1.4% during the session. Those parallel moves show a wider reassessment of AI infrastructure spending, but they do not mean every company faces the same balance-sheet risks.
