Trader consensus on Polymarket prices Robert F. Kennedy Jr. at 49% implied probability to secure the 2028 Republican presidential nomination, ahead of Vice President J.D. Vance (37%) and Secretary of State Marco Rubio (25%), reflecting RFK's rising profile as HHS Secretary leading the Make America Healthy Again (MAHA) initiative amid health policy reforms that appeal to the GOP base's anti-establishment sentiments. Vance benefits from incumbency and Trump's endorsement signals, including recent Iowa campaigning to bolster midterm prospects in early primary states, while Rubio has surged on a viral White House briefing clip from early May 2026 articulating an optimistic vision for America, fueling donor interest and 2028 speculation. The closely contested field anticipates shifts from 2026 midterms, potential Trump endorsements, and primary positioning ahead of the 2028 convention.
