Nine U.S. Companies Top Most Economies by Value as Nvidia Hits $4.24 Trillion
3 articles · Updated · Fortune · Jun 3
Summary
Fortune’s comparison of end-March market caps with 2024 World Bank GDP data found nine U.S. companies are worth more than most national economies, with a 10th—Walmart—just below that threshold.
Nvidia leads the group at $4.24 trillion, a level that would rank fourth globally if it were a country—behind only the U.S., China and Germany, but ahead of Japan.
Apple at $3.73 trillion would sit between Japan and India, while Alphabet, Microsoft and Amazon also exceed the annual output of major economies including the U.K., Italy and Brazil.
The concentration is steep even within the group: the top five—Nvidia, Apple, Alphabet, Microsoft and Amazon—combine for about $16.4 trillion, nearly rivaling China’s GDP.
The analysis compares different measures—market cap reflects investor expectations, GDP annual output—but underscores how heavily corporate value is concentrated at the top of the U.S. market.
