Will Republicans lose a seat in the US Senate for any state Trump won in 2024?

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 (.
