California has overtaken Japan in terms of its Gross Domestic Product (GDP) — a milestone highlighted by Governor Gavin Newsom, who warned that President Donald Trump's tariff policies could endanger the state’s growing prosperity. According to preliminary figures from the US Bureau of Economic Analysis, California posted a nominal gross domestic product (GDP) of $4.1 trillion in 2024. This is higher than Japan’s $4.02 trillion GDP for the same period, as reported by the International Monetary Fund. This places California just behind the United States, China and Germany in total economic output, with the state’s economy growing by 6 per cent in 2024 — outpacing all three of those nations.
