Trader consensus currently favors JD Vance at the top of the 2028 field, reflecting his position as a sitting vice president with national visibility and fundraising capacity. A wide array of potential nominees across both parties, including Alexandria Ocasio-Cortez, Jon Ossoff, Gavin Newsom, and Marco Rubio, keeps probabilities fragmented. With no primaries or caucuses completed and the general election more than two years away, traders price in substantial uncertainty around endorsements, polling trends in key states, and possible late entrants. Historical patterns show early frontrunners often shift as legislative records, campaign infrastructure, and voter coalitions develop. Scheduled events such as midterm results and party conventions could widen gaps among the leaders.
