Stock market today: Dow, S&P 500, Nasdaq futures slide after Nvidia-led slump dampens AI mood again

U.S. stock futures are broadly lower, with the Dow, S&P 500, and Nasdaq all sliding due to continued pressure following Nvidia's recent decline. This renewed slump, particularly in a leading AI stock, signals a potential cooling of investor enthusiasm in the AI sector, raising concerns about broader market momentum. Investors should monitor tech earnings and interest rate sentiment for future direction.
