The 2028 presidential field shows no clear frontrunner, with trader probabilities spread across more than a dozen names from both parties. JD Vance leads at 20.5 percent amid his current administration role, while Alexandria Ocasio-Cortez at 12.7 percent and Gavin Newsom and Jon Ossoff at 9.5 percent each reflect Democratic positioning after the prior cycle. The tight distribution stems from uncertainty over midterm results, legislative records, primary rules, and economic indicators that will shape nomination paths. Recent party conventions, candidate announcements, and polling trends have kept early assessments fluid. Scheduled events such as the 2026 midterms and subsequent primary debates could consolidate support or elevate alternatives by clarifying voter coalitions and electoral math.
