This market will resolve to “Yes” if the Republican party ceases to hold a majority in the United States House of Representatives at any point before polls open for the 2026 U.S. House of Representatives elections scheduled for November 3, 2026. Otherwise, this market will resolve to “No”. A majority in the House of Representatives means holding more than half of the currently seated voting members of the U.S. House at that time, excluding vacant seats. Ties do not qualify as a majority. The primary resolution source for this market will be official information from the United States House of Representatives Press Gallery (https://pressgallery.house.gov/member-data/party-breakdown); however, a consensus of credible reporting may also be used.Republicans currently hold a narrow House majority of 218-212 with four vacancies as the 119th Congress heads into its final months before the November 2026 midterms. Special elections held so far in the 2025-2026 cycle have produced Democratic overperformance relative to 2024 baselines, narrowing the GOP edge in several districts without triggering a shift in overall control. Upcoming specials and any vacancies are unlikely to produce the net seat losses required to flip the chamber before Election Day, given the compressed timeline and structural barriers to rapid change. Trader pricing at 84% for no pre-midterm loss reflects this limited window for disruption alongside the absence of major resignations, party switches, or procedural events that would alter the balance.
