Polymarket Midterm House Seat Markets Put Two GOP Outcomes at 28%

The probability of Republicans winning fewer than 170 seats in the U.S. House after the 2026 midterm elections stood at 28%. Another outcome in the same Polymarket event, a 170-to-174 seat total, also stood at 28%. The below-170 probability was up 27% over 24 hours, while the 170-to-174 probability was up 25%. The figures are market probabilities for possible seat totals, not election results or a count of seats won. Enna Lee reports on investing and digital-asset markets for TokenPost.
