With the 2028 US presidential election still more than two years on the horizon, prediction markets have already begun establishing pricing across the field. Republican succession following Trump's constitutional term limit and Democratic primary matchups are seeing substantial trading volume. Traders who spot mispriced positions early stand to benefit as the candidate pool eventually consolidates.
Republican 2028 Presidential Market
Trump's ineligibility for a third consecutive term leaves the Republican nomination genuinely contested:
- J.D. Vance: ~25-30% — Vice-presidential incumbency edge, Trump endorsement likely
- Ron DeSantis: ~15-20% — Florida governor's popularity, recovery narrative from 2024
- Nikki Haley: ~12-15% — Centrist positioning, international relations background
- Glenn Youngkin: ~7-10% — Two-term Virginia executive, private sector credentials
- Josh Hawley: ~5-8% — Pro-worker, anti-establishment messaging
- Unknown candidate: ~15-20% — Sufficient runway for surprise contenders
Democratic 2028 Presidential Market
- Kamala Harris: ~20-25% — Presumed frontrunner, party establishment backing
- Pete Buttigieg: ~12-15% — Cabinet-level platform as Transportation Secretary
- Gavin Newsom: ~10-13% — California's chief executive, national recognition
- Josh Shapiro: ~8-12% — Governs pivotal Pennsylvania battleground
- Unknown candidate: ~25-30% — Timeline permits emergence of fresh faces
2028 General Election Probabilities

FAQ
- Can a sitting VP (Vance) win the Republican nomination?
- Precedent is mixed. Reagan's successor Bush Sr claimed the 1988 nomination; conversely, Al Gore's 2000 bid as sitting VP fell short. Vance commands frontrunner status in current odds but lacks overwhelming dominance.
- When do 2028 nomination markets resolve?
- Both parties' nomination contracts settle following their respective national conventions — ordinarily scheduled for July and August 2028.
- Are there markets for specific primary states?
- Individual state contests like Iowa's caucuses and New Hampshire's primary typically attract dedicated markets opening 6-12 months prior — explore PolyGram's political betting offerings for availability.
