2022 U.S. Senate elections: Will a Democrat or Republican win this state?

This market will resolve according to the party that controls the Senate following the 2026 U.S. Senate elections scheduled for November 3, 2026.

Senate control is defined as having more than half of the voting Senate members, or half of the voting Senate members and the Vice Presidency.

If the outcome of this election is ambiguous given the above rules, this market will remain open until the Majority Leader of the US Senate is selected following the 2026 US general election, at which point it will resolve to the party the majority leader is affiliated with at the time of their election to that position. If the elected majority leader does not caucus with any listed party this market will resolve “Other”.

Determination of which party controls the Senate after the 2026 US Senate elections will be based on a consensus of credible reporting, or if there is ambiguity, final federal and/or state election authority certification or other final official determination of the 2026 election results.

Will the Republican Party control the Senate after the 2026 Midterm elections?

The 2026 midterm elections for the US Senate is scheduled to be held on November 3, 2026. 

This 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/).

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

This market will resolve to “Yes” if, between the Democratic Party and the Republican Party, the Democratic Party becomes the favorite in the "Which party will win the Senate in 2026?" market (https://polymarket.com/event/which-party-will-win-the-senate-in-2026?tid=1764796601244) for any four-hour period ending by March 31, 2026, 11:59 PM ET or earlier. Otherwise, this market will resolve to “No”.

The Democratic Party will be considered to have become the favorite for any four-hour period if it is ahead of the Republican Party in more individual minutes than the Republican Party is ahead of the Democratic Party during a qualifying time period.

A tie in the number of minutes will not qualify.

The resolution source will be the underlying minute-level price data for the “Which party will win the Senate in 2026?” market, which can be viewed using the bar chart on https://derivative.polymarket.com/index/2026-us-senate-election-democrats-flip-republicans-by or through the “Resolution” tab with the time set to show the four-hour window.
