Trader consensus reflects an 81.5% implied probability that Republicans will lose at least one Senate seat in a state Donald Trump carried in 2024, driven primarily by the open North Carolina race after Sen. Thom Tillis's retirement, where recent polls and prediction markets show Democrats leading 81-20%. Competitive dynamics in Alaska pit Rep. Mary Peltola at 52% against incumbent Dan Sullivan, per trader odds, while Ohio's special election tilts Democratic 54-47%. Senate Republicans express growing concerns over public backlash to Trump administration economic handling and deportation policies, compounded by historical midterm losses for the president's party and upcoming primaries like Texas's Cornyn-Paxton runoff, heightening flip risks in red states.
Experimental AI-generated summary referencing Polymarket data · UpdatedThis market will resolve to "Yes" if Republicans hold fewer seats in the Senate for any state that Trump won in the 2024 US presidential election as a result of the 2026 midterm elections. Otherwise, this market will resolve to "No".
Initial seat counts will be based on the composition of the US Senate as of November 2, 2026, 11:59PM ET.
This market's resolution will be solely based on the number of seats held by the Republican Party in the US Senate for any state won by Trump in the 2024 Presidential election. The loss of particular seat will not count towards a resolution for this market; only the total number of seats held by the Republican Party in a given state will be considered. (e.g. The loss of one of a state's seats by the Republican Party followed by the gain of the other seat would not be sufficient to resolve this market to "Yes".)
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 Democrat 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.
For the purposes of this market, states won by Trump in the 2024 Presidential election include Alabama, Alaska, Arizona, Arkansas, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Montana, Nebraska, Nevada, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia, Wisconsin, and Wyoming. This list is determined by the winner of the electoral votes for each state in the 2024 Presidential election. In states such as Maine and Nebraska, where electoral votes are allocated separately by congressional districts as well as to the statewide winner, only the electoral votes allocated to the statewide winner are considered.
This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
