On 4 November 2025, U.S. markets slid with the S&P 500 down 1.2% and the Nasdaq Composite dipping 2% as investors expressed concerns about elevated valuations in the artificial-intelligence sector. Big-tech growth stocks — many richly priced on future-growth bets — took the hardest hit. Meanwhile, the largest cryptocurrencies also dropped and gold fell around 1.6% amid risk-off sentiment. Analysts warned that after a strong stretch for AI firms, the market may be entering a correction phase.
