California has officially overtaken Japan to become the world's fourth-largest economy, achieving a GDP of more than $4 trillion, which accounts for over 14% of the total US output. This remarkable growth, a 40% increase since 2019, has been largely fueled by the booming technology sector and a significant rise in healthcare contributions. Despite facing ongoing challenges such as wildfires, high housing costs, and economic inequality, California's population of 39 million continues to thrive economically compared to Japan's 123 million. In 2025, California companies secured 62% of all US venture capital, showcasing the state's strong innovation ecosystem. Additionally, California has played a pivotal role in the stock market, contributing more than 40% of the growth in US publicly traded equities since 2019. The state's ports, particularly in Los Angeles and Long Beach, manage over $300 billion in cargo annually, highlighting California's importance in global trade. With a robust education system producing skilled workers, California remains a vital hub for talent, even as some companies relocate operations.
