Ranked: The World’s Biggest
Companies by Revenue
For 12 years, Walmart was the world’s largest company by revenue. In 2025, Amazon took that title with $716.9 billion — separated from Walmart by less than $4 billion. The Fortune Global 500 just had its most profitable year on record. Alphabet became the most profitable company on earth. Here is the complete ranking.

The Fortune Global 500 is the definitive scoreboard of the global economy. 500 companies. $43.1 trillion in combined revenues. $3.39 trillion in profits — the most in the list’s 37-year history. What happens at the top of this list tells you everything about where economic power is moving and where it is not.
“The world’s largest company by revenue is now a cloud computing and e-commerce business — not a supermarket, oil company, or utility. That is a historic shift.”
The Profit Story Is Completely Different From the Revenue Story
Alphabet ranks #8 by revenue. It ranks #1 by profit — with $132.17 billion in net income. That is the second-highest profit figure ever recorded for any company in the Fortune Global 500’s history. The Magnificent Seven (Alphabet, Apple, Amazon, Microsoft, Nvidia, Meta, Tesla) earned $608 billion in combined profit. Tech sector profits rose 36% while revenues rose 20%. The companies making the most money are not always the companies generating the most revenue — and that gap matters enormously.
Healthcare Is Quietly Taking Over the Top 10
Five of the top 10 companies by revenue are US-based. Of those five, three operate primarily in healthcare — UnitedHealth (#4), McKesson (#7), and CVS Health (#9). McKesson broke into the top 10 for the first time, becoming one of the most powerful companies most people have never heard of. It distributes pharmaceutical drugs at a scale that dwarfs most national healthcare systems. The healthcare dominance of the US Fortune Global 500 rankings is one of the list’s most underreported stories.
