US stock market crash deepened Thursday as AI overhype fears collided with bleak jobs data. Dow Jones fell 0.8%, S&P 500 dropped 0.9%, and Nasdaq tumbled 1.6%. Challenger data showed 153,074 layoffs in October — the worst since 2003. Qualcomm sank 4%, AMD lost 6%, and Nvidia dropped 2%. Tesla’s trillion-dollar pay vote loomed large. The selloff reflected growing doubts about inflated tech valuations. With job cuts rising 44% this year, investors fear the AI rally is cracking.
