Republican Presidential Nominee 2028
💡 What the odds say
Most likely: Robert F. Kennedy Jr. at about a 49% chance — a coin toss.
Prediction-market odds are usually well-calibrated — historically, outcomes priced near 70% happen about 70% of the time — but the crowd can still be wrong, and the price can lag the news.
Summary
The 2028 Republican presidential nominee market shows Robert F. Kennedy Jr. leading with 49%, despite his independent status, followed by J.D. Vance at 38% and Marco Rubio at 21%. These odds imply that traders see a wide-open field with Kennedy's unconventional candidacy as the current frontrunner, but significant uncertainty remains as other established Republicans trail behind.
How it resolves
Settled on-chain by UMA's optimistic oracle: once an outcome is clear, anyone can propose the result, which then enters a challenge window where it can be disputed with evidence before it finalizes.

Resolution criteria
This market will resolve to “Yes” if the named individual wins and accepts the 2028 nomination of the Republican Party for U.S. president. Otherwise, this market will resolve to “No”. The resolution source for this market will be a consensus of official Republican Party sources. Any replacement of the Republican nominee before election day will not change the resolution of the market.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.
