Following Donald Trump's 2024 victory and constitutional two-term limit barring his 2028 run, the Republican presidential nomination market reflects trader consensus on an open primary field favoring Trump-orbit figures. Robert F. Kennedy Jr. leads at 49% implied probability after his October 2024 endorsement of Trump, high-profile health policy advocacy, and November 14 nomination for HHS secretary, boosting his anti-establishment appeal to the GOP base despite his independent background. J.D. Vance trails at 36.6% as vice president-elect, positioned as heir apparent via his Midwest battleground roots and MAGA alignment. Marco Rubio's 22.7% draws from his Senate tenure, Florida incumbency, and recent secretary of state nomination, signaling foreign policy strength. Cabinet confirmations, 2026 midterms, and potential Trump endorsements loom as key catalysts.
