Will there be another US government shutdown by January 31 and will the Republican Party win the House in 2026?
Prediction markets currently give a 15% probability that Will there be another US government shutdown by January 31 and will the Republican Party win the House in 2026?. This contract trades at 15¢ on Polymarket, closing November 3, 2026. This conjunction market is pricing in an extremely unlikely dual outcome at just 14¢, implying roughly a 37% chance of shutdown AND a 38% chance of Republican House retention (0.14 = 0.37 × 0.38), yet the astronomical 1121% implied yield on the Yes side suggests severe liquidity constraints with only $19.4k open interest and zero 24-hour volume.
Analysis
This conjunction market is pricing in an extremely unlikely dual outcome at just 14¢, implying roughly a 37% chance of shutdown AND a 38% chance of Republican House retention (0.14 = 0.37 × 0.38), yet the astronomical 1121% implied yield on the Yes side suggests severe liquidity constraints with only $19.4k open interest and zero 24-hour volume. The price has declined 2¢ over seven days despite the neutral regime, and the 6/10 cliff risk index indicates heightened binary event risk as we approach the January 31 shutdown deadline and 2026 midterms, making this a speculative position with minimal trading activity.
Resolution rules
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 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.
