The chance of California’s proposed billionaire wealth tax passing in the upcoming 2026 election is currently estimated at 32%, according to recent data from Kalshi. This measure, known as Proposition 40, aims to impose a one-time 5% tax on the net worth of billionaires residing in the state as of January 1, 2026. The funds generated would largely support healthcare, with smaller portions allocated to education and food assistance. Despite public polling indicating support for the measure, prediction markets suggest passage remains uncertain, with the odds reflecting this cautious outlook.
Kalshi’s report aligns with ongoing public polling, which shows mixed support for the tax. A recent poll indicates 48% in favor compared to 38% opposed, while another shows a closer split with 52% in favor against 46% opposed. These figures suggest that while there is measurable support, passage is not assured. Markets appear to interpret these conditions as indicating a challenging path for the measure, with the current pricing more supportive of a NO outcome.
The market for this event has shown slight fluctuations, with odds for the measure’s passage recently increasing from 28% to 29% before stabilizing at 32%. Key political figures such as California Secretary of State Shirley Weber and Governor Gavin Newsom may play influential roles in the outcome. The market will continue to be monitored as the election date approaches.
