Amazon Overtakes Walmart As America’s Biggest Company

Key Takeaways

• Amazon (AMZN) generated $717 billion in revenue in its latest fiscal year, overtaking Walmart (WMT) ($713 billion) as America’s largest company.

Amazon Ends Walmart’s 13-Year Run

In 2026, Amazon displaced Walmart as the world’s largest company by revenue, ending Walmart’s 13-year reign at the top.

This shift follows a decade in which Amazon’s revenue surged alongside the growth of e-commerce and online shopping. The company’s strategic investments also expanded over this period, including its $13.7 billion acquisition of grocery retailer Whole Foods in 2017.

The COVID-19 pandemic also affected the retail race between Amazon and Walmart. Lockdowns and isolation pushed many consumers toward online shopping at a scale not seen before, helping Amazon’s revenue jump by more than a third between 2019 and 2020.

Amazon’s displacement of Walmart makes the 1994-founded online retailer just the fourth company to top the Forbes 500 in the list’s 72-year history. Prior to Walmart, General Motors and ExxonMobil held the title. In 2025, GM’s revenue reached $185 billion, while ExxonMobil led the American oil industry at $332 billion.

Healthcare: Soaring Revenues

Healthcare companies generate over $2.7 trillion in combined revenue across America’s 50 largest companies, led by UnitedHealthcare at $448 billion.

Nearly one out of every five dollars in the U.S. economy is spent in the healthcare sector, which is reflected in the massive revenues of companies like CVS Health ($402 billion), Cigna ($275 billion), and Johnson & Johnson ($94 billion).

Technological advancements and an aging U.S. population have driven growth in the sector, with firms like UnitedHealthcare and Cigna each posting over 10% year-over-year revenue growth.

America’s Core Sectors

The technology sector generated over $1.6 trillion in revenue from just its six top firms, with Apple ($416 billion) and Google parent company Alphabet ($403 billion) leading the way.
