Trader consensus on the 2028 Republican vice presidential nominee remains fragmented, with no single figure exceeding 23% amid uncertainty over the eventual presidential nominee and shifting alignments within the party. Tucker Carlson, Marco Rubio, Ivanka Trump, Joe Kent, and Marjorie Taylor Greene cluster near the top due to their national profiles, media reach, and perceived alignment with Trump-era priorities, while lower-priced options like J.D. Vance reflect positioning as a likely presidential contender rather than running mate. Rubio’s role as secretary of state and Vance’s vice presidency provide institutional visibility that sustains their shares, yet the absence of formal endorsements or primary positioning keeps probabilities compressed. Midterm results, cabinet reshuffles, or early primary signals could widen gaps by clarifying frontrunners and preferred ticket balances.
