Hot September CPI Reading Sends AI Stocks Reeling Across Asia

The Consumer Price Index for September came in at 3.7%, a figure that reignited concerns the Federal Reserve will need to keep interest rates higher for longer. U.S. stock futures fell in response, with traders pricing back in the odds of further Fed tightening. The reaction spread fastest through Asian markets, where AI-linked stocks that had led gains for months gave back ground as investors reassessed how much high-growth, high-multiple names can withstand a tighter rate environment. The move compounded existing unease over the AI trade: reports that Anthropic's revenue growth is cooling as the company prepares for a public listing had already put investors on edge before the CPI print landed. What remains unresolved is whether this is a one-month inflation blip or the start of a trend that forces the Fed's hand. Investors will be watching the next inflation reports and any Fed commentary closely to see if Wednesday's reaction was an overreaction or the start of a repricing.
