Nvidia reached an unprecedented milestone this week, becoming the first publicly traded company to top a $4 trillion market capitalization. The surge in the chipmaker’s value reflects its pivotal role at the heart of the artificial intelligence revolution, fueled by soaring demand for its graphics processing units that power AI models worldwide.

Nvidia’s shares this week rose as much as 2.5% to at $164.10 on Thursday, gaining 0.75% during the day and cementing its position ahead of long-standing tech giants such as Apple and Microsoft. With a market capitalization of $3.75 trillion, Microsoft is the second-largest U.S. company. Its shares recently traded at $503, up 1.3%.

Despite global trade tensions and uncertainty surrounding tariffs, Nvidia reported a 69 percent year-over-year revenue increase to $44.1 billion in its latest quarter, with earnings per share of 81 cents.

The milestone drew attention at the highest levels of government. Nvidia CEO Jensen Huang met with President Donald Trump at the White House yesterday, where the president praised the company’s achievement as a symbol of American innovation and industrial strength.

“Nvidia is up 47% since trump tariffs. USA is taking in hundreds of billions of dollars in tariffs. Country is now ‘back’,” trump wrote.
