Trader consensus on Polymarket prices Robert F. Kennedy Jr. as the narrow 2028 Republican presidential nominee favorite at 49%, driven by bets on his Make America Healthy Again movement's crossover appeal and his cousin Jack Schlossberg's March 7 statement confirming a "definite" run, despite diverging from GOP straw polls where Vice President J.D. Vance leads—such as his recent CPAC win—but shows slippage in New Hampshire surveys. Secretary of State Marco Rubio's 20.5% reflects a poll surge after reports of President Trump privately asking big donors to choose between Rubio and Vance, with most favoring Rubio. Midterm results and 2027 primary declarations loom as key catalysts.
