Nvidia became the first publicly traded company to surpass a $4 trillion market valuation after its shares rose as much as 2.8 percent to $164.42 in New York trading on Wednesday. The milestone, briefly reached intraday on July 9 and confirmed with a $4.004 trillion close on July 10, cements the California-based chipmaker’s status as the world’s most valuable company, eclipsing Microsoft at about $3.7 trillion and Apple at roughly $3.1 trillion. The advance crowns a rally powered by explosive demand for Nvidia’s graphics processing units, which underpin the generative-AI boom. The stock has climbed about 22 percent in 2025 and more than 1,300 percent since late 2022, giving the company the heaviest single weighting in the S&P 500 at around 7.5 percent. Nvidia previously crossed the $2 trillion mark in February 2024 and the $3 trillion threshold in June 2025, reaching each milestone faster than any company in market history. Chief Executive Officer Jensen Huang has leveraged the company’s dominance in high-end AI chips and data-center systems to secure multi-billion-dollar orders from cloud providers and enterprise customers, offsetting headwinds from U.S. export restrictions to China. Analysts say continued AI infrastructure spending could keep Nvidia’s growth outpacing the broader market even amid tariff and regulatory uncertainty.
