US stock market crashes hard: Why Dow, S&P 500, Nasdaq are falling big today? Is AI era gone before it begins as Nvidia and Palantir lead tech selloff

US stock market plunged Friday as panic gripped investors and tech giants led the rout. The Nasdaq sank 1.9%, the S&P 500 fell 1.1%, and the Dow slipped 0.7% as sellers dumped growth stocks. Nvidia plunged over 4% after a US ban on AI chip exports to China, while Palantir, Tesla, and SoFi extended steep losses. Consumer sentiment dropped to 50.3 and inflation expectations hit 4.7%, stoking fear of slowdown. Take-Two crashed 9% on a GTA 6 delay, while Expedia jumped 17% on strong earnings. The AI stock bubble may be cracking faster than expected.
