**Trader consensus assigns an 89.8% probability to “Other (including Ossoff)” emerging as the 2028 presidential odds leader by November 30, reflecting the fluid early stage of the cycle after the 2026 midterms.** No major candidates have declared, leaving name recognition and recent electoral results as primary drivers. Jon Ossoff’s decisive Georgia Senate reelection lifted his profile in prediction markets, where he currently tops overall winner odds ahead of JD Vance despite repeated public statements of no presidential interest. Vance leads Republican primary polling averages, while Democratic polling shows Kamala Harris and Gavin Newsom ahead of Ossoff in some surveys. The high “Other” price and modest shares for named alternatives capture uncertainty over whether any single figure will consolidate a clear lead in the next two weeks amid ongoing polling volatility and absence of formal announcements.
