On October 14, 2026, AI infrastructure stocks experienced a significant decline following unexpected US inflation data. The market reacted to concerns over potential Federal Reserve interest rate hikes, which directly impact companies reliant on borrowed capital for expansion.
The sector saw a total loss of approximately $80 billion in market capitalization during a single trading session. Individual stock performance reflected this pressure: CoreWeave shares fell by 15–16%, Nebius declined by 10–11%, Dell dropped by about 11%, and Oracle shares shed 8–9%.
CoreWeave, which holds $22 billion in bonds and $26 billion in loans, saw its bond yields trade near 15% during the selloff. This trend highlights the increasing cost of debt for companies that depend on external financing rather than internal cash flow.
Corporate debt issuance within the AI sector has been steadily decreasing. After reaching a peak of $113 billion in June 2026, monthly issuance dropped to $23 billion by September, representing a decline of roughly four-fifths over the quarter.
