Which company ranked second on the 2024 Fortune 500?

Amazon ranked second on the 2024 Fortune 500, behind Walmart.

Fortune’s 2024 Fortune 500 ranks the largest companies based in the United States by revenue, using figures from the companies’ relevant fiscal years. Walmart held first place, while Amazon took the No. 2 position. Apple ranked third, UnitedHealth Group fourth, and Berkshire Hathaway fifth.

Amazon’s placement reflects the scale of several businesses operating under one corporate umbrella. Its revenue includes online retail, physical stores, third-party marketplace activity, subscriptions such as Prime, advertising, and Amazon Web Services. That broad mix helped it remain ahead of other major American corporations even though the Fortune 500 is a revenue ranking, not a measure of profit, market value, or brand popularity.

A frequent mix-up is confusing the Fortune 500 with the Fortune Global 500. The U.S.-only Fortune 500 placed Amazon second in 2024; the global list also placed Amazon second, but it compares companies worldwide. Rankings can change quickly because Fortune updates them annually using new revenue figures.
