The 2028 Democratic vice-presidential nominee market remains tightly contested because no presumptive presidential nominee has emerged, leaving traders to weigh a wide field of potential running mates across family connections, rising state officials, and high-profile names. Chelsea Clinton leads at 23.1 percent followed closely by Hunter Biden at 20.1 percent and Ro Khanna at 17.2 percent, reflecting early speculation over dynastic or progressive figures rather than established frontrunners. Phil Murphy, Rahm Emanuel, and others cluster in the mid-teens as traders price in different paths depending on the eventual presidential ticket. With more than thirty candidates between 1 percent and 23 percent, the fragmented pricing captures the absence of defining events such as primaries, conventions, or major endorsements that could consolidate support before the cycle intensifies.
