Which company became the first publicly traded company valued above US$4 trillion in July 2025?

The story behind the answer

Nvidia became the first publicly traded company valued above US$4 trillion in July 2025.

Nvidia passed the US$4 trillion market-capitalization mark during trading in July 2025, according to reports tracking the company’s share price and outstanding stock. The milestone followed its earlier breakthroughs at US$1 trillion, US$2 trillion, and US$3 trillion as demand for AI computing accelerated.

Nvidia’s leading products are GPUs used in data centers, gaming systems, professional visualization, and scientific computing. Its data-center business became especially important as cloud providers and technology companies built large clusters for generative AI.

The valuation describes the market’s pricing of Nvidia’s equity, not the replacement cost of its factories or the amount of money in its bank accounts. Because the figure is market-based, it can change rapidly with earnings forecasts, competition, supply conditions, and investor expectations.
