The 2024 United States Senate elections will be held on November 5, 2024, with 33 of the 100 seats in the Senate being contested.

This market will resolve to "Yes" if as a result of the 2024 U.S. Senate elections 49 or fewer of voting Senate members are Republican. Otherwise, this market will resolve to "No".

​​A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2024 Senate elections are conclusively called by this market's resolution sources.

Zal de Republikeinse Partij precies 49 Senaatszetels hebben na de tussentijdse verkiezingen van 2026?

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/).

The 2026 midterm elections are scheduled to be held on November 3, 2026, with congressional primaries running from March through September.

This market will resolve according to the number of Republican Senate incumbents who do not win their nominating election to move on to the general election as a result of the 2026 midterm primary elections.

An incumbent will be considered not to have won their election if they are not declared the winner of the election they sought, including if they withdraw, suspend, or otherwise leave the race at any point after officially registering as a candidate, regardless of the reason. Incumbents who do not officially register as candidates for reelection will not be considered.

This market will resolve based on the results of all Senate nominating elections, including party primaries, top-two or jungle primaries, and primaries for special elections, that are scheduled to occur between March 1 and September 30, 2026. If a required runoff for any such election or a subsequent qualifying round in a non-partisan primary system could change the market’s outcome, the market will remain open until that contest is conclusively called by this market’s resolution sources.

A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time of their nominating election. 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 prior to the conclusion of the relevant nominating election.

The resolution source for this market will be the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all relevant nominating elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on official state certification of the nominating election results.

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.
