California voters are preparing to decide on Proposition 40, a legislative proposal that introduces a one-time 5% wealth tax. The levy targets state residents whose net worth exceeds $1 billion. The initiative currently has the backing of the Service Employees International Union–United Healthcare Workers West, while California Governor Gavin Newsom remains in opposition.
Recent polling data shows that the proposal has not yet secured a majority of public support. Market sentiment regarding the potential passage of the tax has shifted slightly, with the perceived probability of a positive outcome rising from 28% to 31.5% over the past week.
With 34 days remaining until the vote, market analysts are closely watching for new endorsements or financial commitments from stakeholders. These developments are expected to influence the final outcome and economic outlook as the election date approaches.
