Market Discussion
As of August 2026, prediction markets and political commentary describe the 2028 Democratic presidential primary as a wide-open, crowded field with no consensus frontrunner, with leading candidates like Gavin Newsom, Jon Ossoff, Alexandria Ocasio-Cortez, and Pete Buttigieg having relatively low implied probabilities of winning the nomination [^][^][^][^][^][^]. An 'invisible primary' is underway, with numerous governors and senators actively building national profiles, and some analytical models identify a disconnect between market-priced favorites and polling-based projections for certain candidates [^][^][^][^][^][^]. The Democratic National Committee proposed a 2028 nominating calendar beginning with South Carolina on January 22, 2028, and overall prediction market sentiment leans toward a Democratic victory in the 2028 US Presidential Election [^][^][^][^][^].
