South Carolina’s placement as the first contest on the 2028 Democratic calendar, confirmed by the DNC in summer 2026, underscores the state’s large Black electorate and has shaped trader pricing, with Kamala Harris at 27.5% and Jon Ossoff at 19.5% reflecting their respective national name recognition and Southern positioning. National polls continue to show Harris ahead, yet prediction markets price the field more tightly because no major candidate has declared and participation remains uncertain. Gavin Newsom, Raphael Warnock, and Cory Booker follow at lower levels amid similar name-ID dynamics, while the absence of formal campaigns or recent polling specific to the Palmetto State keeps implied probabilities clustered and responsive to any early endorsements, midterm results, or entry announcements before the January 2028 vote.
