Claim: California's GDP growth since 2019 is more than any other state in the United States.
Verdict: Partially True (85% confidence)
Explanation: The claim that California's GDP growth since 2019 is more than any other state in the United States is incorrect. Sources [16] and [17] indicate that California's economic growth is significant but not the highest among all states. Specifically, California is ranked second in GDP growth, with Washington state having a faster rate of expansion in the first quarter of 2026. This directly contradicts the claim that California's GDP growth is the highest in the nation.
