Nvidia made history in July by becoming the first public company to surpass $4 trillion in market value when its stock closed at approximately $164.10 per share on July 10. The milestone reflects the company’s central role in powering artificial intelligence infrastructure, as its high-performance chips are now integral to data centers across industries.

Since crossing the $1 trillion threshold in mid-2023, Nvidia has soared well beyond, outpacing fellow tech giants like Apple and Microsoft—both maintaining valuations above $3 trillion. Nvidia’s rise underscores investor confidence in AI’s long-term growth.

Despite geopolitical tensions and export restrictions to China, which threatened to trim revenues, Nvidia’s valuation continued to climb. On July 9, the company briefly touched $4 trillion intraday before settling just under that mark. The next day, the stock reclaimed the milestone in closing value.

By mid-2025, Nvidia held a roughly 7.3 percent share of the S&P 500, higher than Apple’s and Microsoft’s shares, demonstrating the company’s outsized influence in the U.S. equity market.
