The Californian economy has overtaken Japan’s to become the fourth-largest in the world by gross domestic product (GDP).

That is according to data from the International Monetary Fund (IMF) and the Bureau of Economic Analysis (BEA), a fact highlighted by the California governor’s office as it battles President Donald Trump’s trade policies.

The IMF put Japan’s GDP at $4.02 trillion in 2024. That compares to California’s GDP of $4.1 trillion for the same year, according to the BEA’s figures. It places the state behind only the United States, China, and Germany in global rankings.
