The Fortune 500 list has ranked Walmart as the largest U.S. company by revenue at $648 billion for 2023, followed closely by Amazon at $575 billion. Berkshire Hathaway, Apple, and UnitedHealth Group round out the top five, with revenues of $439 billion, $383 billion, and $368 billion, respectively. This marks a notable shift from 2019, where energy giant Exxon Mobil was in the top five but has since been replaced by healthcare leader UnitedHealth Group.
The significant growth of Amazon, which has more than doubled its revenue since 2019, highlights the increasing role of technology across various sectors. Companies like Walmart are expanding their e-commerce capabilities, while UnitedHealth Group is integrating tech solutions to enhance patient experiences.
The evolving rankings indicate a trend where technology is blurring traditional sector classifications, suggesting ongoing changes in how industries operate and compete.
