The 2028 presidential nomination process remains highly fragmented with no dominant frontrunner, as reflected in trader consensus showing JD Vance at 21.1% and the next several candidates clustered in the low-to-mid teens or single digits. Both parties feature crowded fields of potential contenders including sitting senators, governors, and prominent House members, with early positioning shaped by post-2024 party dynamics, midterm outcomes, and candidate statements on policy priorities. This dispersion keeps implied probabilities dispersed because the primary calendar, convention delegate math, and swing-state electoral considerations are still distant. Key upcoming catalysts such as 2026 midterm results, formal announcements, polling shifts among key voting blocs, or endorsements could consolidate support and create clearer separation ahead of the 2028 primaries.
