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.Trader consensus on Polymarket prices HHS Secretary Robert F. Kennedy Jr. as the frontrunner at 49% implied probability for the 2028 Republican presidential nomination, ahead of Vice President J.D. Vance (37%) and Secretary of State Marco Rubio (21%), driven by RFK Jr.'s high-profile Make America Healthy Again (MAHA) agenda and recent speech touting HHS successes on March 28 amid ongoing agency reforms. His cousin's March 7 assertion of a "definite" 2028 bid fueled speculation, despite low favorability polls and a federal judge's March 16 halt to vaccine policy changes. Vance's odds dipped to a recent low following President Trump's repeated polling of donors and advisers favoring Rubio—elevated by Iran airstrikes and diplomacy—over Vance as successor, highlighting an early primary contest shaped by administration roles and midterm dynamics ahead.
