Largest company in the world

By market capitalization, Nvidia is the largest company in the world as of July 2026, valued at roughly $4.7 trillion. Its dominance in AI chips has made it the most valuable public company on Earth.

As of mid-2026 the top five are, roughly: Nvidia (~$4.7T), Alphabet (~$4.3T), Apple (~$4.3T), Microsoft (~$2.8T) and Amazon (~$2.6T). Values move daily, so treat exact figures as a snapshot.

Yes. As of July 2026 Nvidia has overtaken Apple to become the world's most valuable company, driven by demand for its AI data-center chips. Apple sits around third, close to Alphabet.

Market capitalization (market cap) is the total value of a company's shares: share price multiplied by the number of shares outstanding. It is the standard way to rank how large public companies are, though it reflects investor expectations, not just current profits.

Nvidia is closest, hovering near $4.7 trillion in mid-2026, so it is the frontrunner to cross $5 trillion first. Nothing is guaranteed, market caps swing with earnings, AI demand and the wider market, but the race is currently Nvidia's to lose.

As of 2026, essentially yes: the entire top 10 by market cap is technology and technology-adjacent, dominated by AI, chips, cloud, software and internet platforms. Older leaders from energy, finance and retail have been pushed down the list.

Nvidia designs the GPUs that train and run the AI models behind the current boom. As companies race to build AI, they buy enormous quantities of Nvidia's data-center chips, driving revenue and, with it, one of the fastest climbs to the top of the market-cap rankings in history.
