Nvidia passed Microsoft in market cap on Tuesday, once again becoming the most valuable publicly traded company in the world.
Shares of the artificial intelligence chipmaker rose about 3% on Tuesday to $141.40, and the stock has surged nearly 24% over the past month as Nvidia’s growth has persisted even through export control and tariff concerns.
The company now has a $3.45 trillion market cap. Microsoft closed Tuesday with a $3.44 trillion market cap.
Nvidia has been trading places with Apple and Microsoft at the top of the market cap ranks since last June. The last time Nvidia was the most-valuable company was on Jan. 24.
Last week, Nvidia reported 96 cents in adjusted earnings per share on $44.06 billion in sales in its fiscal first quarter. That represented 69% growth from the year-ago period, an incredible growth rate for a company as large as Nvidia.
Nvidia’s growth has been fueled by its AI chips, which are used by companies including OpenAI to develop software such as ChatGPT.
