America’s largest state economies rank alongside some of the biggest economies in the world. Even further down the list, many individual states produce hundreds of billions of dollars in economic output each year.
This map, via Visual Capitalist's Gabriel Cohen, pairs each U.S. state with the country closest to it in nominal gross domestic product (GDP) in 2025, using data from the Bureau of Economic Analysis and the IMF’s World Economic Outlook.
The Big Four State Economies
At $4.3 trillion, California would rank among the world’s five largest economies if it were an independent country. Its closest match on the map is the United Kingdom.
Texas, meanwhile, has a $2.9 trillion economy, putting it closest to Russia. Both are major energy powerhouses, particularly in oil and gas.
