California’s proposed 2026 Billionaire Tax Act has become a focal point of controversy as the state plans to impose a 5% wealth tax targeting billionaires, sparking backlash from some of the wealthiest individuals. The New York Post reports that California aims to pursue billionaires who have left the state in opposition to the tax, which could impact the state’s ability to collect significant revenue. The tax initiative, Proposition 40, has qualified for the November 3, 2026, ballot and aims to use the revenue primarily for healthcare, alongside education and food assistance. Amid this, only six billionaires have reportedly left California, potentially affecting $27 billion in expected tax revenue.
The market for the California billionaire wealth tax appears to reflect growing uncertainty about the measure’s passage. Recent reports suggest increased opposition, with key billionaires potentially funding campaigns against the tax. This development aligns with the observed decrease in the probability of the tax passing, with the market pricing a 29.5% chance of a YES outcome, down from 34% a week ago. The market’s movement suggests that participants may view the opposition as a significant factor in the upcoming November ballot.
