Traders currently price "≤47" at 26% for "Republican Senate seats after the 2026 midterm elections?". Full distribution: ≤47 26%, 51 14%, 49 14%, 50 13%. The market has traded $2.8M in total volume and resolves Nov 3, 2026. Republicans currently hold a 53-47 Senate majority and defend 20 of the 33 seats contested in November 2026, while Democrats defend 13 and require a net gain of four seats for control. Trader probabilities remain dispersed across 47–52 seats because recent special-election results show Democrats outperforming 2024 baselines by double digits amid low presidential approval, inflation concerns, and foreign-policy developments including Iran. Key variables include Democratic targeting of vulnerable Republican-held seats in states such as North Carolina and Ohio, Republican opportunities against retiring Democrats in Georgia and Michigan, candidate recruitment quality, and any late-cycle shifts in national conditions before Election Day.
