The wide-open 2028 Democratic presidential field has produced fragmented odds on the vice-presidential slot, with no candidate exceeding low double digits amid uncertainty over the eventual nominee. Traders assign the highest implied probabilities to figures offering distinct ticket-balancing attributes, such as swing-state executive experience for Gretchen Whitmer or Elissa Slotkin, progressive visibility for Alexandria Ocasio-Cortez, or red-state appeal for Andy Beshear. Other contenders draw support from Senate records, demographic considerations, or perceived crossover potential. Recent polling shows Kamala Harris leading early presidential preferences, though prediction markets favor different names, underscoring how the presidential outcome will likely drive VP consolidation once clearer frontrunners and party priorities emerge ahead of the convention.
