US Stock Market Rout Wipes Out $2.5 Trillion as AI Stocks Tumble

The American stock market experienced a significant downturn as investors retreated from AI-related holdings, erasing substantial wealth in a matter of hours. The sell-off was particularly pronounced among technology and artificial intelligence companies, which have dominated market gains over the past year. The Nasdaq-100, which tracks the 100 largest non-financial companies on the Nasdaq exchange, bore the brunt of the decline as major constituents registered steep losses.

The $2.5 trillion decline represents one of the sharpest single-day contractions for the index's heaviest-weighted companies. The pullback reflects growing concerns among investors about valuations in the AI sector and questions surrounding profitability timelines for companies betting heavily on artificial intelligence technologies. Market analysts attributed the move partly to profit-taking following an extended rally in technology stocks.

The broad-based decline underscores the concentration of market gains among a handful of mega-cap technology firms, many of which have been driven by optimism around artificial intelligence applications. The sudden reversal highlights the volatility inherent in momentum-driven market rallies and raised questions about the sustainability of recent valuations in the sector.

The sell-off had ripple effects across global markets, with investors reassessing exposure to technology and AI-dependent equities. The movement marked a departure from the sector's steady appreciation earlier in the year, signaling a potential shift in market sentiment toward high-growth technology stocks.
