Some of the largest F500 companies have revenues that dwarf the GDPs of most of the world’s economies.
Here is where each company would rank if it were a country:
Nvidia, which has become the defining infrastructure stock of the artificial intelligence era, tops the corporate list at $4.24 trillion—a figure that would place it fourth globally, ahead of Japan and India, and just behind Germany. Apple, at $3.73 trillion, would rank sixth, between Japan and India. Alphabet, at $3.48 trillion, falls just below India and above the United Kingdom.
Microsoft, at $2.75 trillion, would rank between France and Italy, while Amazon, at $2.24 trillion, sits just below Canada and above Brazil.
The next tier is tighter. Broadcom ($1.47 trillion) and Meta Platforms ($1.45 trillion) would rank between Spain and Indonesia. Tesla ($1.39 trillion) narrowly trails Indonesia ($1.40 trillion)—by less than $6 billion. Berkshire Hathaway, at $1.03 trillion, lands between the Netherlands and Switzerland.
Walmart, which topped the Fortune 500 revenue rankings for 13 consecutive years before Amazon claimed the title in 2026, sits just outside this group at roughly $913 billion in market cap, below Switzerland.
The concentration is notable even within the list itself. The top five companies alone—Nvidia, Apple, Alphabet, Microsoft, and Amazon—have a combined market value of roughly $16.4 trillion, which could rival China’s GDP.
