Nvidia's stock market value ended the trading session above $4 trillion for the first time on Thursday, solidifying the chipmaker's position as Wall Street's central player in a race to dominate AI technology.

NVIDIA was briefly worth $4 trillion this week. The tech giant passed that milestone and became the first $4 trillion company following a 2.5% increase in stock value at one point on July 9, 2025. The valuation of NVIDIA has since dropped to around $3.97 trillion.

NVIDIA’s market value broke a record on Wednesday after dipping in spring amid political uncertainty and chip restrictions.

Nvidia achieved a $1 trillion market value for the first time in June 2023 and tripled it in about a year, faster than Apple and Microsoft, the only other U.S. firms with market values above $3 trillion. Microsoft is the second most valuable U.S. company, with a market capitalization of $3.73 trillion. Its shares dipped 0.4% on Thursday.

The AI revolution has helped chipmaking giant Nvidia become the first company in history to reach a $4trn valuation.

Nvidia Corp. became the first company in history to achieve a $4-trillion market valuation, cementing its status as a kingpin in the global financial market.

Here's why Nvidia will likely become the first company to surpass $4 trillion in market value, what Nvidia and Microsoft must do to continue rising in price, and whether either growth stock is a buy now.
