The world\u2019s economic gyrations make it tricky to put California\u2019s economic might into a global perspective.<\/p>\n
There\u2019s no perfect yardstick of business heft. Even the often-used benchmark \u2013 gross domestic product, a broad measure of business output \u2013 is subject to various swings, including currency changes and numerous statistical revisions.<\/p>\n
Nonetheless, my trusty spreadsheet<\/a> used two recently updated GDP figures to calculate the theoretical world in which California is a stand-alone economy on the global stage.<\/p>\n State-level GDP figures from the U.S. Bureau of Economic Analysis<\/a> were compared with the International Monetary Fund<\/a>\u2018s worldwide estimates of economies over the past 10 years. The business output was tracked in U.S. dollars and was not adjusted for inflation.<\/p>\n Here\u2019s what this vanity scorecard tells us.<\/p>\n The world\u2019s top two economies have been the same for 10 years. For 2025, the U.S. was No. 1 at $30.77 trillion, followed by China at $19.63 trillion.<\/p>\n Germany has been No. 3 for the past three years, with $5.05 trillion of business output last year.<\/p>\n Japan, the previous No. 3, was the world\u2019s fourth-largest economy by this GDP metric last year at $4.44 trillion.<\/p>\n Then, California ranked No. 5, with an average GDP of $4.3 trillion in 2025. California has been the world\u2019s fifth-largest economy for all 10 years tracked.<\/p>\n After California, the United Kingdom came in sixth at $4 trillion, followed by India at $3.92 trillion.<\/p>\n So what about 2026?<\/p>\n The IMF projects the same top three: The U.S. ($32.4 trillion), China ($20.9 trillion) and Germany ($5.5 trillion).<\/p>\n Japan\u2019s estimate for this year is $4.38 trillion, the United Kingdom\u2019s is $4.26 trillion, and India\u2019s is $4.15 trillion.<\/p>\n What about California?<\/p>\n Well, if the state\u2019s economy can grow at the same pace as the IMF\u2019s 2026 estimate for the entire U.S., California\u2019s GDP would finish 2026 at $4.52 trillion.<\/p>\n That would make the Golden State the world\u2019s fourth-biggest economy on this bragging rights yardstick.<\/p>\n
