Republican Senate seats after the 2026 midterm elections?
Prediction market · Polymarket
Overview
The 2026 midterm elections are scheduled to be held on November 3, 2026. This market will resolve according to the number of seats held by the Republican Party in the US Senate as a result of the 2026 midterm elections. This market will resolve based on the results of all Senate elections, including special elections, that are scheduled to occur in November 2026 as of October 31, 2026. If a required runoff for any such election could change the market’s outcome, the market will remain open until that runoff is conclusively called by this market’s resolution sources. If a Senate seat is vacant but a corresponding election is not held in November 2026, the seat will be considered held by the party of the seat's most recent incumbent. A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 Senate elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democratic or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the Senate elections are conclusively called by this market's resolution sources. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all Senate elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.

"description": "The 2026 midterm elections are scheduled to be held on November 3, 2026.\n\nThis market will resolve according to the number of seats held by the Republican Party in the US Senate as a result of the 2026 midterm elections.\n\nThis market will resolve based on the results of all Senate elections, including special elections, that are scheduled to occur in November 2026 as of October 31, 2026. If a required runoff for any such election could change the market’s outcome, the market will remain open until that runoff is conclusively called by this market’s resolution sources.\n\nIf a Senate seat is vacant but a corresponding election is not held in November 2026, the seat will be considered held by the party of the seat's most recent incumbent.\n\nA candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 Senate elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democratic or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the Senate elections are conclusively called by this market's resolution sources.\n\nThe resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all Senate elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.",

"context_description": "Republicans' current 53-47 Senate majority confronts historical midterm losses for the president's party, with trader consensus pricing a tight cluster around 48-50 GOP seats post-November 2026 elections due to a favorable yet competitive map requiring Democrats a net gain of four for control. Early April polls show narrow leads in battlegrounds like Florida (Moody R 43-42 Vindman D) and contentious primaries in Michigan (El-Sayed gaining), Texas (Cornyn-Paxton runoff), Maine (Platner leads Dem primary over Collins), North Carolina (open Tillis), and Ohio (Brown D vs. Husted R), amplified by gas prices above $4/gallon and Iran-related economic pressures. Heavy Senate Leadership Fund spending defends GOP seats, but Democratic recruits like Cooper, Peltola, and Pappas sustain contention; June primaries, Trump endorsements, and economic trends could tip balances.",
