Wall Street loses $3.2 trillion as AI fears trigger Nasdaq plunge

Wall Street suffered a "Black Thursday," losing $3.2 trillion in value as the Nasdaq plunged 5.5% on AI-related fears. The selloff erased all post-election gains. The Dow Jones fell 3.44% to 51,521.28 points, the S&P 500 dropped 4.3% to 7,353.80, and the Nasdaq slid 5.52% to 24,315.00. Investors fled tech stocks for a second day over concerns about data center expansion. The market turmoil was triggered by a decisive Democratic victory in the US midterm elections, which investors worry could slow AI infrastructure growth.
