Republicans hold a 53-47 Senate majority following the 2024 elections, with 22 of their seats contested in the November 2026 midterms compared to 13 Democratic seats. Several GOP-held seats lie in states Donald Trump carried in 2024, including competitive contests in North Carolina, where incumbent Thom Tillis is retiring, and others such as Ohio, Iowa, Alaska, and Texas. Historical patterns show the president's party typically loses ground in midterm cycles, reinforced by recent generic ballot polling and special election results showing Democratic overperformance in Trump-won districts. Rating firms classify multiple Republican defenses as toss-ups or leans, creating a consensus among traders that at least one net loss remains probable before Election Day.

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, 11:59 PM ET. Vacant seats will be treated as held by the party affiliation of the most recent member to hold that seat.
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 a 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".)
All regular and special Senate elections that determine representation in the upcoming 120th Congress and are scheduled to take place in November 2026 as of October 31, 2026 are included. Runoffs for qualifying elections will determine attribution of the relevant seat, even if they take place after November 2026. Vacant seats for which no election or special election to fill the seat is scheduled to take place in November 2026 as of October 31, 2026 will be treated as held by the party affiliation of the most recent member to hold that seat.
For seats contested in the specified election, seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected.
For seats not contested in the specified election, seats are attributed to the party that holds the seat as of the date of the election. If a current sitting member of the U.S. Senate who is not up for election changes party affiliation or vacates their seat after the date of the election, the seat is attributed to the party under which the member was affiliated at the time of the election.
Senate members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with, a party will be included in that party’s count. If the caucus decisions of members of the Senate elected as independents cannot be determined on the date of the election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party.
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.
The resolution sources for this market will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.Republicans hold a 53-47 Senate majority following the 2024 elections, with 22 of their seats contested in the November 2026 midterms compared to 13 Democratic seats.
