Trader consensus on Polymarket heavily favors Rep. Eric Swalwell (58.5%) as the 2026 California governor winner following his surge to the top in the March 11 Emerson College poll, where he led the June top-two primary field at 17-25% amid 25% undecideds, overtaking prior Republican frontrunners like Steve Hilton (now 9.8%) and Riverside Sheriff Chad Bianco. Tom Steyer (12.3%) and San Jose Mayor Matt Mahan (7.5%) trail as other Democrats in the fragmented 20+ candidate field, raising risks of a GOP lockout in the primary that advances the top two vote-getters regardless of party to November. Swalwell's momentum stems from national name recognition and recent attacks from rivals highlighting the race's intensity, though low voter enthusiasm and undecideds keep the contest fluid ahead of the June 2 primary.
