With the 2028 US presidential election still more than two years off, prediction markets are already actively quoting the field, featuring Republican succession prospects following Trump's constitutional ineligibility and Democratic primary contenders. Those who deposit funds early and identify mispriced candidates before the candidate pool consolidates stand to capture substantial returns.
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 from 2024 primary setback
- Nikki Haley: ~12-15% — Establishment Republican coalition, diplomatic experience
- Glenn Youngkin: ~7-10% — Two-term Virginia governor, entrepreneurial credentials
- Josh Hawley: ~5-8% — Pro-worker, nationalist positioning
- Unknown candidate: ~15-20% — Sufficient breadth for late-stage entrants
Democratic 2028 Presidential Market
- Kamala Harris: ~20-25% — Presumed frontrunner, party machinery backing

- Gavin Newsom: ~10-13% — West Coast governor, media presence
- Josh Shapiro: ~8-12% — Competitive-state Pennsylvania executive
- Unknown candidate: ~25-30% — Timeline permits fresh contenders to emerge
