2026 Balance of Power: D Senate, D House

This market will resolve according to the result of the 2026 United States midterm elections. A party will be considered to have 'control' of the House of Representatives, if they win a majority of voting seats. A party will be considered to have 'control' of the Senate if they have more than half of the voting Senate members, or half of the voting Senate members and the Vice President. A candidate's party is determined by their ballot-listed or otherwise identifiable affiliation with that party at the time the 2026 United States midterm 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 that they most recently expressed their intent to caucus with at the time the 2026 United States midterm elections are conclusively called by this market's resolution sources. If control of the House is ambiguous given the above rules, this market will resolve according to the party affiliation of the first Speaker of the US House who is selected following the 2026 United States midterm elections. If control of the Senate is ambiguous given the above rules, this market will resolve according to the party affiliation of the first Majority Leader of the US Senate who is selected following the 2026 United States midterm elections. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called winners of the House and Senate in the 2026 United States midterm elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.

The prediction market for the 2026 Balance of Power: D Senate, D House indicates a 43% probability that the Democratic party will control both the Senate and the House following the midterm elections. This assessment is informed by current political trends and polling data, which suggest a competitive landscape with no clear majority for either party. The market price would likely increase if there were significant shifts in voter sentiment or major gaffes by Republican candidates, potentially altering the electoral landscape. Conversely, a strengthening of Democratic leads or a notable scandal involving prominent Democratic figures could cause the price to decline. The market will resolve on November 3rd, 2026, following the conclusion of the midterm elections.
