Analysis generated Aug 31, 2026
Kalshi prices Marco Rubio at 28% as the 2028 Republican VP nominee, roughly five times higher than J.D. Vance at 6%, reflecting Rubio's visibility as Secretary of State and his secondary status in the presidential primary where Vance is the clear frontrunner. Trump's recent remarks that Vance is "most likely" his successor while also suggesting a Vance-Rubio ticket position Rubio as the consensus second-choice among Republicans and the top vice-presidential prospect. The fragmented field below 5% shows no organized challengers to these two.
As of September 11, 2026, the Kalshi odds for 2028 Republican VP nominee are: Marco Rubio: 28%, J.D. Vance: 6%, Donald J. Trump: 5%, Donald J. Trump Jr.: 4%, Erika Kirk: 4%. These probabilities are derived from real-money trading and update in real time.
