Story summary

On November 3, 2026, California voters went to polls to decide on Proposition 40, which proposed a one-time 5% tax on fortunes above $1 billion. The measure aimed to raise funds for California’s Medicaid program by taxing about 200 individuals, but it was ultimately defeated according to projections released on November 10, 2026. Opponents of the proposition argued that such a tax would cause wealthy residents and sports team owners to leave the state, while supporters saw it as an opportunity to address economic inequality. The vote was closely watched globally as a test case for wealth redistribution policies.
