Democrats hold an overwhelming edge in the combined market because traders assign them roughly 85-90 percent odds of flipping the House in the November 2026 midterms. Republicans currently defend a narrow majority after 2024, yet face the historical pattern of the president’s party losing seats in midterms, compounded by recent generic-ballot polling that shows Democrats ahead by roughly six points. Ongoing appropriations disputes, compressed legislative calendars after the August recess, and competing continuing-resolution proposals have sustained shutdown risk into the fall funding deadline. The joint probability therefore tracks closely with standalone House-control prices, with the modest discount on the Republican-linked outcome reflecting both lower base rates for GOP retention and the possibility that a funding lapse could still be averted before the election.

This market will resolve according to the combined outcome of whether there will be another US government shutdown by January 31 (https://polymarket.com/event/will-there-be-another-us-government-shutdown-by-january-31?) and according to which party will win the House in 2026 (https://polymarket.com/event/which-party-will-win-the-house-in-2026?).
The rules and resolution criteria are as follows:
1. Will there be another US government shutdown by January 31?
This market will resolve according to whether the U.S. Office of Personnel Management (OPM) announces another federal government shutdown due to a lapse in appropriations by January 31, 2026, 11:59 PM ET.
Partial shutdowns count as shutdowns; announcements of office closures due to holidays or inclement weather do not qualify as a shutdown.
The resolution source for this market will be OPM’s Operating Status page (https://www.opm.gov/policy-data-oversight/snow-dismissal-procedures/current-status/).
2. Which party will win the House in 2026?
This market will resolve according to the party that wins control of the United States House of Representatives in the 2026 United States midterm election.
A party wins control of the United States House of Representatives if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the chamber will be deemed controlled by the party with which the first elected Speaker of the House of the Congress that convenes after the 2026 midterm election is affiliated.
The following rules govern the counting of seats for determining which party wins control of the chamber.
All House elections in the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th Congress are included. Where a seat is decided by a runoff, the runoff result will determine attribution of that seat.
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.
House members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with a party are included in that party’s count. If the caucus decisions of members of the House 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.
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.This market will resolve according to the combined outcome of whether there will be another US government shutdown by January 31 (https://polymarket.com/event/will-there-be-another-us-government-shutdown-by-january-31?) and according to which party will win the House in 2026 (https://polymarket.com/event/which-party-will-win-the-house-in-2026?).

2. Which party will win the House in 2026?
This market will resolve according to the party that controls the House of Representatives following the 2026 U.S. House elections scheduled for November 3, 2026.
House control is defined as having more than half of the voting members of the U.S. House of Representatives.
If the outcome of this election is ambiguous given the above rules, this market will remain open until the Speaker of the House is selected following the 2026 U.S. general election, at which point it will resolve to the party the Speaker is affiliated with at the time of their election to that position. If the elected Speaker does not caucus with any listed party this market will resolve “Other”.
Determination of which party controls the House after the 2026 U.S. House elections will be based on a consensus of credible reporting, or if there is ambiguity, final federal and/or state election authority certification or other final official determination of the 2026 election results.Democrats hold an overwhelming edge in the combined market because traders assign them roughly 85-90 percent odds of flipping the House in the November 2026 midterms.
