Wall Street loses $1.9 trillion as Nasdaq plunges 5% in 24-hour selloff

Wall Street experienced a massive stock selloff within 24 hours, with the Nasdaq falling about 5% and $1.9 trillion in market value erased, as post-election euphoria turned to panic. The Dow Jones lost over 1,700 points, erasing all gains from the previous session, while the S&P 500 fell over 4% in its worst day since April 2025. The selloff was driven by fears that the Democratic midterm victory could lead to stricter regulations on data centers and artificial intelligence infrastructure, particularly in Texas. Semiconductor and AI-related stocks suffered the heaviest losses, with Arm down 17% and AMD falling 15%. Barclays estimated volatility-control funds could sell $135 billion in futures within 48 hours, potentially amplifying the decline. The VIX fear index surged over 50% to 28 points, while oil prices rebounded to near $98 per barrel.
