US indices open mixed, S&P 500 hits a new record high

The S&P 500 rose to a new record high on Thursday, as Nvidia’s AI-driven rally showed no signs of slowing.

Nvidia continues to break records, whether in terms of speed of rise or size, as it has reached a level that a global company has never reached before, after its market value exceeded $3.43 trillion, on its way to the fourth trillion.

Nvidia stock jumped more than 2%, building on the previous session’s gains that cemented the chipmaker as the most valuable public company. Shares of the de facto market leader are up 174% this year as the artificial intelligence boom continues to boost stocks even as consumers show signs of a slowdown in spending and some potential economic weakness.
