Quick Summary

Californians are voting on Proposition 40, which proposes a one-time 5% tax on the net worth of individuals exceeding $1 billion. If passed, California would be the first state in America to implement such a tax, with revenue aimed at replacing federal funding cuts for healthcare programs. The measure has sparked intense debate and significant financial opposition from wealthy tech entrepreneurs like Google co-founders Sergey Brin and Larry Page, who are cutting ties with California in anticipation of its approval. Governor Gavin Newsom warns that the proposal could cause a mass exodus of millionaires, while supporters argue it is crucial for addressing wealth inequality and healthcare funding gaps.

Story summary

Californians voted on November 3, 2026, regarding Proposition 40, which proposed a one-time 5% tax on fortunes above $1 billion. If passed, this would be the first such wealth tax in the U.S., with revenue dedicated largely to California’s Medicaid program. Billionaires like Elon Musk and Sergey Brin opposed it, spending over $333 million campaigning against it, arguing that it would drive wealthy individuals out of the state. Supporters, including Vermont Senator Bernie Sanders, framed the proposal as a crucial step toward addressing wealth inequality. Despite the debate, Proposition 40 had split even liberal leaders, with California Governor Gavin Newsom warning it could lead to job losses and higher costs for sports teams in cities like Inglewood.
