Market fears over AI developments led to a significant sell-off, with the Nasdaq 100 falling 2% and the S&P 500 down 1.3%. Major tech stocks like Broadcom and Oracle saw declines of over 11% and 6%, respectively, due to project delays. In the crypto market, Bitcoin fell 2.5% to $90,000, while Ethereum dropped 5% to $3,070, as altcoins also faced pressure amid rising U.S. Treasury yields and the Federal Reserve's cautious approach to interest rate cuts.
