Intro

This market on Kalshi tracks which party will control both chambers of Congress after the 2026 midterm elections. The leading outcome—Democratic control of both the House and Senate—stands at 43.0%, while a split scenario with Democrats holding the House and Republicans controlling the Senate is at 39.0%. Resolution will be determined on February 1, 2027, based on which party's leadership holds the Speaker of the House and President pro tempore of the Senate positions. Watch the November 2026 election results, as they will directly determine the party composition of both chambers and settle this market.

Kalshi

This combination market requires all specified components to occur simultaneously for a Yes resolution. The four possible outcomes are: Democrats control both chambers, Republicans control both chambers, Democrats control the House while Republicans control the Senate, or Republicans control the House while Democrats control the Senate. Control is determined by the party affiliation of the Speaker of the House and President pro tempore of the Senate on February 1, 2027. If any single component becomes impossible or resolves to No, the entire contract immediately resolves to No. Each component is resolved according to standard Kalshi control rules.
