The selling followed fresh US inflation figures that raised concerns about borrowing costs. Companies building data centers need large amounts of capital to buy chips, secure power, and expand computing capacity.

AMD Stock Drops Alongside Other Chipmakers

Nvidia fell 3.2%, Broadcom lost 3.1%, and Taiwan Semiconductor Manufacturing declined 3.4%. Marvell Technology dropped 8.7%, as selling spread across major suppliers of processors used in AI systems.

September US inflation reached 3.7%, above market forecasts. The Nasdaq Composite fell 1.9%, while the S&P 500 lost 1.1% as investors weighed the prospect of higher interest rates.

The broader market selloff also affected data center operators and server makers. Oracle lost about 9%, while Dell Technologies declined roughly 11% during Wednesday’s session.

CoreWeave Debt Adds Pressure to AI Spending

CoreWeave shares dropped about 16% as yields on its corporate bonds approached 15%. Higher yields reflect lower bond prices and growing concern about the company’s ability to finance further expansion.

On X, investor Chamath Palihapitiya shared a chart showing CoreWeave‘s 2032 bond yield had touched 15%. Elon Musk replied, “Yikes,” drawing further attention to financing risks.

Reporting on CoreWeave’s bond selloff also noted that quarterly net interest costs reached $640 million. Chief Executive Mike Intrator defended the company’s business model despite the market decline.

Debt concerns matter for AMD stock because some customers finance chip purchases through borrowing. Higher financing costs could lead those companies to review new orders, although no company has confirmed spending cuts.

AMD Faces Nvidia Competition Ahead of Earnings

AMD reported $6.7 billion in second-quarter data center revenue, more than double the year-earlier figure. Nvidia reported $89 billion from its data center business in its latest quarter.

Coverage of Nvidia’s latest decline described a wider retreat among chip stocks. Separately, AMD introduced its Helion AI rack design on October 12, with partner systems planned for November.

AMD reports third-quarter earnings on November 3. On Thursday, TSMC reported a 69% rise in quarterly profit, citing AI demand. Planned cloud spending updates will offer further evidence of future chip demand.
