U.S. equities suffered a historic selloff on 5 November 2026, with the S&P 500 falling 4.36%, the Nasdaq Composite plunging 5.52% into correction territory more than 11% below its October record, and the Dow Jones Industrial Average dropping 3.44% to 51,523.06 — the sharpest single-day declines since April 2025. Market-value losses set records: S&P 500 constituents shed roughly $2.9 trillion, Nasdaq Composite components lost $2.5 trillion, and the “Magnificent Seven” technology giants erased about $1.04 trillion combined. Semiconductor stocks bore the brunt, with the Philadelphia Semiconductor Index collapsing 12%; Nvidia fell 9.26%, vaporizing $447 billion in market value on its own.
The trigger was not a single data release but the convergence of the midterm outcome and monetary-policy expectations: Democrats’ sweep of both chambers led investors to price in tighter AI regulation — including limits on data-center expansion, grid-cost allocation and AI-specific taxes — while October core CPI, released on 10 November, held at 0.3% month-on-month for a third straight month, reinforcing bets on a December Fed hike and further compressing richly valued technology shares.
Analysts emphasized that the crash was driven less by confirmed recession data than by a collision between the AI growth narrative and policy uncertainty plus elevated interest rates. A potential slowdown in data-center construction could materially drag on AI-related investment that accounted for roughly one-third of U.S. economic growth in 2025–2026, with spillovers already visible across Asian and European semiconductor supply chains.
