With the 2028 presidential field still wide open two years out, trader consensus reflects a fragmented field where no candidate has consolidated support. JD Vance leads Republican probabilities due to his established role within the party and positioning after the prior cycle, while Democratic odds remain split among Alexandria Ocasio-Cortez, Jon Ossoff, Gavin Newsom, and others, underscoring the absence of a clear frontrunner. Primary dynamics, including potential midterm outcomes, early endorsements, fundraising trends, and state-level polling, continue to shape implied probabilities. Upcoming convention timing, candidate announcements, and any shifts in voter coalitions could create separation as the nomination process advances.
