Traders see a fluid 2028 Democratic presidential nomination race with no dominant frontrunner more than two years before primaries. Alexandria Ocasio-Cortez has gained ground in prediction markets and early-state polling through progressive mobilization, while Jon Ossoff has risen sharply on platforms like Kalshi amid perceptions of broad appeal and vocal opposition positioning. Gavin Newsom’s earlier lead has eroded amid tightening odds and questions over personal matters. Kamala Harris and Josh Shapiro trail significantly in market pricing despite occasional polling strength. The near-even probabilities around 50 percent reflect a crowded field where small shifts in sentiment, endorsements, or candidate announcements could quickly reorder standings before October 31.
