Changing of the Guard

Claiming the top position as the largest U.S. company is still Walmart, closely trailed by the relentless Amazon. Having doubled its revenue since 2019, Amazon now sits at the second rank. The departure of Exxon Mobil from the top ranks made way for healthcare stalwart UnitedHealth Group (NYSE: UNH) to step in.
