JD Vance holds an 81% implied probability as the 2028 presidential odds leader on November 30, reflecting trader consensus on his strong positioning within Republican primary dynamics and limited immediate challengers. Other named candidates, including those at 50% each, Alexandria Ocasio-Cortez at 11.7%, Gavin Newsom at 3.4%, Marco Rubio at 2.5%, and Kamala Harris at 2.5%, trail due to narrower paths in their respective parties amid current polling trends and electoral math. Recent developments such as party leadership consolidation and absence of major disruptions in the past 30 days have reinforced these probabilities, though scheduled events like mid-term outcomes or early endorsements could still shift positioning before the resolution date.
