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 ## Evidence you can inspect _These labels describe how a claim relates to the question.

No individual review. It rests on 30 claims from 11 publishers; anything not reported in those sources is not represented here. The report recorded 6 resolution risks, listed with this brief. - The market title says 'by January 31' without specifying year, though the description clarifies January 31, 2026 11:59 PM ET for the shutdown condition. - The end date of the market (2027-02-01) suggests the House question resolves in early 2027, but there is no explicit date boundary stated for the House resolution beyond the 2026 midterm election cycle and potential January 4, 2027 caucus announcement deadline. - The January 31 shutdown deadline applies only to the shutdown sub-question; the House question resolves on a much later timeline, creating an asymmetric resolution window for the combined market. - If no party wins a majority of voting seats, the Speaker affiliation governs, which introduces subjectivity about timing and Speaker election outcomes. - Independent members' caucus decisions may delay resolution of the House sub-question up to January 4 of the year following the 2026 election. - The official resolution source listed at the bottom (OPM page) applies only to the shutdown question, not the House question, potentially causing confusion. ## Publication history - Published 4 November 2026; research dated 3 November 2026. - Published 1 November 2026; research dated 1 November 2026. ## Since the previous brief Compared with research dated 1 November 2026.
