The 2028 Democratic presidential nomination market reflects a wide-open field more than two years before primaries, with no candidate exceeding 17 percent as traders weigh multiple paths to the nomination. Gavin Newsom, Alexandria Ocasio-Cortez, and Jon Ossoff sit within roughly one percentage point of each other because each brings distinct coalition strengths—state-level executive experience, progressive activist networks, and Senate visibility—without a decisive national polling or fundraising edge yet. The compressed top tier and long tail of lower-priced names illustrate how early positioning, midterm outcomes in 2026, and potential late entrants could shift probabilities before any formal contests begin.
