California Billionaire Tax Clears Path to November Ballot

California officials have confirmed that a measure to slap a one-time tax of up to 5 percent on residents and trusts worth more than a billion dollars has gathered enough valid signatures to reach the November ballot. The proposal would raise an estimated 100 billion dollars, with most of the money directed toward healthcare programs and smaller shares going to food aid and education. Backers claim the levy is needed to offset federal healthcare reductions pushed through by President Trump and congressional Republicans.

Yet prediction markets are already treating the idea as a long shot. Traders on Kalshi and Polymarket put the odds of final passage at roughly 18 to 19 percent even if the measure appears on the ballot. Those same markets had shown much higher odds of qualification before recent reports surfaced that Governor Gavin Newsom was quietly working to block the initiative before the June 25 certification deadline.

The tax would allow payments to be spread over five years and would exempt certain assets such as real estate. Supporters gathered nearly 1.6 million signatures in April, almost twice the number required. The secretary of state’s office verified enough of them this week, though the measure could still be withdrawn before it is formally placed on the ballot.

Critics point out that California already relies heavily on taxes paid by its highest earners. That dependence has produced sharp swings in state revenue whenever investment gains or executive bonuses fluctuate. Adding another layer of taxation on the same narrow group risks accelerating departures of wealthy residents and businesses already sensitive to the state’s high costs and regulatory burden.

Newsom had previously signaled opposition to the plan, and the sudden drop in market odds after reports of his behind-the-scenes efforts suggests Sacramento insiders view the measure as more trouble than it is worth. The governor’s reluctance is not surprising given the state’s track record of volatile budgets that swing with the fortunes of a few thousand top taxpayers.

The proposal’s backers frame it as a straightforward fix for vulnerable residents hurt by changes in Washington. Opponents counter that it offers no durable solution and instead doubles down on an approach that has already left the state’s finances exposed to the decisions of a small number of high-net-worth individuals. With markets assigning such low odds of success, the November contest may prove more expensive for both sides than decisive for state policy.
