Nvidia was the first company to reach a $4 trillion market capitalization during trading in July 2025.
Nvidia crossed the $4 trillion mark intraday on July 9, 2025, according to reports of its market value on U.S. exchanges. The event followed an extraordinary rise in demand for GPUs and networking equipment used in artificial-intelligence data centers.
Nvidia’s position was built on more than chip design alone. Its CUDA software ecosystem, high-performance accelerators, networking products, and close relationships with major cloud and technology companies all contributed to investor expectations about future AI infrastructure spending.
An intraday market cap is calculated from a temporary share price and can fall below the threshold before the closing bell. It should therefore be distinguished from a record closing value. The milestone also illustrates why rankings of the world’s richest companies by market cap can change rapidly when a small percentage move represents hundreds of billions of dollars.
