Today, four of the top 20 companies in the Fortune 500 are health insurers, with combined revenues of nearly $1.1 trillion in 2023. Going further, the collective revenues of the nation’s six largest for-profit health insurers accounted for almost 30% of U.S. health spending last year. By comparison, they made up under 10% of the total in 2011.
