With the 2028 US presidential election still over two years on the horizon, prediction markets have already begun establishing prices across the field. Republican succession following Trump's constitutional ineligibility and Democratic primary competition are both seeing substantial trading volume. Those who spot mispriced opportunities early stand to benefit as the candidate roster eventually consolidates.
Republican 2028 Presidential Market
Trump's third-term prohibition leaves the Republican nomination wide open:
- J.D. Vance: ~25-30% — Vice-presidential incumbency edge, Trump-backed
- Ron DeSantis: ~15-20% — Gubernatorial approval ratings, recovery narrative from 2024 primary setback
- Nikki Haley: ~12-15% — Centrist coalition, diplomatic experience
- Glenn Youngkin: ~7-10% — Two-term Virginia executive, private sector track record
- Josh Hawley: ~5-8% — Pro-labour, anti-establishment positioning
- Unknown candidate: ~15-20% — Sufficiently dispersed field permits surprise contenders
Democratic 2028 Presidential Market
- Kamala Harris: ~20-25% — Presumptive favourite, party establishment backing
- Pete Buttigieg: ~12-15% — Cabinet-level prominence, media exposure
- Gavin Newsom: ~10-13% — State executive profile, national recognition
- Josh Shapiro: ~8-12% — Battleground state governor, electoral significance
- Unknown candidate: ~25-30% — Timeline permits emergence of fresh contenders
2028 General Election Probabilities

FAQ
- Can a sitting VP (Vance) win the Republican nomination?
- Historical precedent shows vice-presidential nominees possess structural advantages yet face no guarantee of success. Bush Sr (1988) inherited Reagan's mantle; Gore's 2000 run fell short despite the office. Prediction markets treat Vance as the leading contender without assigning overwhelming probability.
- When do 2028 nomination markets resolve?
- Both Republican and Democratic nomination markets settle following their respective party conventions — customarily in July or August 2028.
- Are there markets for specific primary states?
- Iowa caucus and New Hampshire primary markets typically launch 6-12 months ahead of voting — consult PolyGram's political markets section for availability.
