The 2028 Democratic presidential nomination market remains fragmented because no major candidate has declared and early polling shows divided support across governors, senators, and House progressives. Trader pricing reflects AOC’s rising profile from progressive primary wins and her refusal to rule out a bid, alongside Jon Ossoff’s appeal as a swing-state senator despite his focus on Georgia reelection. Gavin Newsom’s positioning as a Trump critic and the DNC’s revised calendar—starting in South Carolina—add uncertainty, while Kamala Harris’s support has softened in markets even as some surveys keep her competitive. The absence of a clear frontrunner and ongoing midterm dynamics keep probabilities clustered in the teens, with separation likely to emerge only after 2026 results and formal entries.
