Nvidia shares closed up 5% to $1,224.40 on Wednesday, giving the company a market cap above $3 trillion for the first time as investors continue to clamor for a piece of the company at the heart of the boom in generative artificial intelligence. Nvidia’s milestone is the latest stunning mark in a run that has seen the stock soar more than 3,224% over the past five years. The company will split its stock 10-for-1 later this month.
