Key Takeaways▸ California’s nonpartisan top-two primary system is forcing traders to price who advances, not just who wins, creating more complex and active markets.▸ Polymarket has drawn over $9.1M and Kalshi over $6.5 million in volume on the race, forecasting a Republican advancer but a Democratic general election winner.▸ With no incumbent and polling still unsettled, traders are eyeing real trading opportunities ahead of the June 2 primary.The 2026 California primary race for governor is wide open and already drawing serious money on prediction markets. Gov. Gavin Newsom is term-limited and eyeing a 2028 presidential run. The race for the governor seat is drawing a wide range of candidates heading into the June 2 primary. The state’s top-two primary forces a different kind of betting logic, and traders are trying to decide whether the field breaks toward a Democratic advance, a Republican advance, or something stranger.The primary has drawn more than $9 million in volume on Polymarket, while Kalshi traders are a bit slower to move on the race with just over $300,000 in its primary advancers market.
