6 min read2028 Republican Nominee: JD Vance Leads Polymarket at 54%
With $117 million in trading volume, Polymarket's 2028 Republican Presidential Nominee market is one of the largest political markets on the platform. Vice President JD Vance dominates at 54%, positioning himself as the clear frontrunner for Trump's succession. Here's the full breakdown.
Current Odds (December 2025)
- JD Vance: 54% (-144 implied)
- Marco Rubio: 7% (+1329 implied)
- Vivek Ramaswamy: 5%
- Ron DeSantis: 4%
- Donald Trump Jr.: 3%
- Total Volume: $117 million
- Liquidity: $7 million
Why JD Vance is the Heavy Favorite
Vance's dominance in this market isn't just name recognition - it's structural advantage:
- Trump's endorsement: Trump cannot run for a third term and will likely back his VP
- Incumbency advantage: As sitting VP, Vance has national platform and fundraising network
- Age factor: At 41, Vance would become the third-youngest president ever
- MAGA continuity: Represents seamless transition from Trump era
Key Context
Trump is term-limited by the 22nd Amendment and cannot seek a third term. The Republican Party will need a new standard-bearer, and Vance is positioned as the natural successor.
The 46% Case Against Vance
Despite his frontrunner status, 46% of the market bets against Vance. Here's why:
- 3 years is eternity in politics: A lot can change by 2028
- VP curse: Sitting VPs rarely win nominations smoothly (Gore 2000, Biden struggled)
- Trump could sour: If Trump's second term falters, association hurts Vance
- DeSantis redemption: Florida Governor could rebuild after 2024 collapse
- New faces: Unknown candidates often emerge (Obama 2008, Trump 2016)
Second-Tier Candidates
Marco Rubio (7%)
As Trump's Secretary of State, Rubio has foreign policy credentials and establishment appeal. He ran in 2016 and could position as the "experienced statesman" alternative to Vance.
Vivek Ramaswamy (5%)
The biotech entrepreneur and 2024 candidate appeals to younger MAGA voters. He'd need to differentiate from Vance while maintaining Trump coalition support.
Ron DeSantis (4%)
After his disastrous 2024 campaign, DeSantis has work to do. But he remains Florida Governor until 2027 and could rebuild his brand if given opportunity.

Trading Strategy
Value Assessment
At 54 cents, YES on Vance offers 85% return if he wins. The question: is 54% accurate for an event 3 years away? Historical VP nomination rates, combined with Trump's unique influence, suggest Vance may be appropriately priced. The value play might be betting on specific challengers at long odds if you have conviction.
