PolymarketRules
This market will resolve according to the party that wins control of the United States Senate in the 2026 United States midterm election.
- A party wins control of the United States Senate if it wins a majority of the chamber’s voting seats.
- If no party wins a majority of voting seats, the party that wins control of the chamber is the party that wins half of the voting seats and holds the Vice Presidency.
- If the outcome remains ambiguous after applying the above criteria, the chamber will be deemed controlled by the party with which the first selected President Pro Tempore of the Congress that convenes after the specified election is affiliated.
- The following rules govern the counting of seats for determining which party wins control of the chamber.
- 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.
