Democrats hold a substantial lead in 2026 House forecasts, with polling averages showing a generic ballot advantage of roughly five points and models assigning them an 80-90% chance of gaining the majority currently held by Republicans. This positioning stems from standard midterm dynamics against the president's party and competitive district trends. Congress recently enacted a continuing resolution funding agencies through December 11, averting an October lapse but deferring full-year appropriations negotiations until after the November 3 elections. Historical patterns of repeated funding disputes in 2026, combined with the post-election lame-duck window and January 31 resolution trigger, sustain trader expectations of another shutdown. The resulting implied probability heavily favors the combined outcome of a shutdown paired with Democratic House control.

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.
