Kamala Harris remains the early polling leader for the 2028 Democratic presidential nomination, averaging roughly 20-30% support in recent national surveys amid a wide-open field that includes Gavin Newsom, Pete Buttigieg, Alexandria Ocasio-Cortez, and Jon Ossoff. Prediction markets, however, assign her low single-digit implied probabilities of securing the nomination, reflecting trader assessment of structural headwinds including her 2024 general election defeat, internal party hesitation about another bid, and expectations of a crowded primary. Harris has kept her intentions open while focusing on 2026 midterm surrogacy and has faced private pressure from advisers to decide on a run by year-end, with some donors and allies signaling preference for newer candidates. No major candidate has formally declared, and developments through December could influence positioning if she signals intent or if polling shifts among key voting blocs.
