The Class of 2026: Meet the 12 companies making their Fortune 500 debut

From crypto companies to mattress makers, these companies made it in the list’s 72nd year.

Making the Fortune 500 list is no small feat, yet every year a fresh group of companies elbows its way in by displacing incumbents and reshuffling the ranks of American corporate power. 

To make it on the list of the top 500 companies in the U.S. by revenue, a company has to meet strict requirements, including a minimum of $7.5 billion in revenue in 2026. This year 12 companies made it on the list for the first time across industries like crypto, mattresses, and natural gas.
