- Shares of Alphabet (GOOG) edged higher ahead of the market open after news Google is rolling out a broader array of artificial intelligence chips, aiming to capitalize on its rapid ascent as a challenger to Nvidia in a market worth hundreds of billions of dollars. The company is introducing two new variations of its tensor processing units, or TPUs, custom-made semiconductors that help develop and run AI software. The latest chips will address the need for confidential computing and help models access a wider range of information when handling queries.

- Shares of KKR & Co.
