Manifold MarketsRules
This market will resolve according to the party that wins control of the Pennsylvania State Senate in the 2026 Pennsylvania midterm election.
- A party wins control of the Pennsylvania 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 Lieutenant Governor's Office as a result of the election.
- 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 State Senate that convenes after the specified election is affiliated.
- If no such President Pro Tempore is chosen by March 31, 2027, 11:59 PM ET, this market will resolve to "Other".
- The following rules govern the counting of seats for determining which party wins control of the chamber.
