Nvidia became the world’s most valuable public company in June 2024 after Nvidia’s stock split.
Nvidia overtook Microsoft and Apple in market capitalization on June 18, 2024, as its shares continued rising on demand for AI infrastructure. The company’s market value reached roughly $3.34 trillion during that trading session.
Nvidia’s ten-for-one stock split took effect earlier in June 2024. A split changes the number of shares and the price per share but does not, by itself, change the company’s total market capitalization. The later price rise reflected investor buying, not the arithmetic of the split alone.
Nvidia’s position was closely tied to its data-center business, including graphics processing units, networking products, and software. Rankings can change rapidly because they depend on live share prices, so this historical answer should not be treated as a permanent current ranking.
