The Aporia · California voters defeat billionaire tax proposal that divided Democrats

California voters have rejected Proposition 40, which aimed to impose a one-time 5% tax on billionaires' wealth, potentially raising $100 billion for healthcare. The measure faced strong opposition, particularly from Governor Gavin Newsom and Google co-founder Sergey Brin, who argued it would drive wealthy individuals out of the state and harm California's economy. Despite support from some Democratic leaders like Senator Bernie Sanders, Prop 40 was defeated due to significant spending by its opponents and division within the Democratic party over the best approach to taxing the rich.

Story summary

Californians voted against Proposition 40 on November 3, 2026, which would have imposed a one-time 5% tax on the fortunes of billionaires with assets over $1 billion. The measure aimed to raise approximately $100 billion for healthcare programs but was defeated with 53.8% voting against it and 47.2% in favor, according to The Associated Press.

Proposition 40 divided liberal leaders nationally; while Vermont Senator Bernie Sanders framed the proposal as a step toward reducing wealth inequality, Democratic Governor Gavin Newsom warned that it would drive wealthy residents out of California. Opponents argued that Proposition 40 was not sustainable and failed to address broader economic issues effectively. The campaign over Proposition 40 became the most expensive in state history due to significant contributions from both supporters and opponents, including tech billionaires like Elon Musk.
