U.S. equity futures traded mixed in early Friday action after a sharp tech sector sell-off on Oct. 21, 2026, driven by growing market concerns that the artificial intelligence trade might be faltering in the near term. Futures tied to the S&P 500 sat flat, while Dow Jones Industrial Average futures dropped 120 points, or 0.23%. Meanwhile, Nasdaq-100 futures ticked up 0.25% following a brutal prior session.
S&P 500 and Nasdaq Post Heaviest Losses Since Summer
During regular trading, the S&P 500 sank 1.2% and the Nasdaq Composite slid 2.6%. The broad market benchmark posted its worst single session since July, while the tech-heavy Nasdaq recorded its worst day since June. The Dow Jones Industrial Average bucked the broader downward trend to close marginally higher.
Concerns surrounding artificial intelligence spending weighed heavily on investor sentiment, dragging the broader U.S. tech sector down 3% on the day. Nvidia dropped 4.4%, Alphabet fell 3.2%, and Advanced Micro Devices declined 8.1% as losses spread across various segments of the technology industry.
Capital Scarcity Hits the AI Buildout
Nvidia CEO Jensen Huang addressed capital constraints during the buildout in a Thursday interview with CNBC. “There’s a scarcity of capital. The demand for the capital is much greater than the availability of the capital,” Huang said when discussing the neocloud segment of the AI infrastructure expansion.
Ed Yardeni, president of Yardeni Research, characterized the prevailing AI trade as a bubble on Thursday. However, he argued that some release of pressure could benefit the broader financial ecosystem. “Taking some air out of the AI bubble is a good thing. I don’t think it’s going to burst and create problems for the economy,” Yardeni said, pointing to competition from the bond market.
