Nvidia rules the artificial intelligence world, but that world is getting a little smaller—and more crowded. 

The chip maker now synonymous with AI reported another quarter of blowout sales and earnings growth late Tuesday. Revenue more than tripled to $18.1 billion thanks mostly to soaring sales at the company’s data center segment, which is now four times as large as its other businesses combined. Nvidia’s strong lead in the chips necessary to power generative AI technologies such as ChatGPT is also evident in its surging bottom line. Adjusted operating margins hit a record high of 64% in the fiscal third quarter ended October, far above the company’s average of 38% for the same quarter over the past five years.
