The 2028 Democratic vice presidential nominee market remains fragmented, with no outcome above 25% implied probability, because the presidential ticket itself has yet to take shape and the convention lies more than two years away. Traders assign the highest probabilities to candidates who combine name recognition with perceived appeal to key voting blocs, including rising state-level figures and high-profile personalities outside traditional politics. Limited recent movement reflects the absence of decisive signals such as presidential primary polling, major endorsements, or convention dynamics that historically narrow running-mate fields. Future catalysts that could separate contenders include primary results, shifts in party leadership, or public positioning by potential presidential nominees.
