**No major Democratic contender has formally declared a 2028 presidential bid as of mid-October 2026, leaving the field wide open ahead of the November midterms and a planned post-election “What’s Next” summit in Denver.** Traders assign the highest probability to “Other” because the first announcement could come from an unlisted figure or a lower-profile contender once midterm results clarify party dynamics. Among listed names, Andy Beshear’s active role as Democratic Governors Association chair, book tour, and recent South Carolina travel give him an edge in early positioning. Gavin Newsom has signaled a post-midterm decision but pledged not to run if Kamala Harris enters, while Pete Buttigieg and Ro Khanna have been more explicit about considering bids and maintaining national visibility. Harris remains publicly undecided, prioritizing midterm efforts, which contributes to the spread across multiple moderate-to-progressive options.
