U.S. stock markets saw mixed performance on Friday (October 16) as investors reassessed risks within the artificial intelligence (AI) sector, ahead of potential further tightening by the Federal Reserve. While the S&P 500 and the Dow Jones edged slightly into positive territory, the Nasdaq 100 fell by approximately 0.5% under pressure from technology stocks.
Shares of CoreWeave plunged nearly 7%, extending their weekly decline to roughly 18%. This pressure has heightened concerns regarding credit risks for AI infrastructure companies—a sector that requires substantial financing to build out data centers and computing capacity.
Sentiment toward the AI sector has also been dampened by questions surrounding the revenue growth of companies like Anthropic; some market participants argue that current growth levels do not yet justify the lofty valuations seen across the technology and semiconductor industries. Furthermore, the prospect of sustained high interest rates adds pressure on companies with significant debt, as the cost of capital could rise.
Semiconductor stocks faced particular strain, with shares of Micron, AMD, and Marvell each falling by as much as 3%. These concerns were compounded by U.S. consumer and producer inflation data released this week, which indicated that price pressures remain elevated—increasing the likelihood that the Federal Reserve will maintain a restrictive monetary policy for longer.
Meanwhile, Tesla shares rose by about 1% following the unveiling of a new Roadster model featuring propulsion technology from SpaceX. This collaboration has fueled market speculation regarding deepening ties between the various companies owned by Elon Musk. Nevertheless, Wall Street’s primary focus remains on the valuations within the AI sector, financing risks, and the future trajectory of Federal Reserve interest rates.
