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 218-214 majority in the House with one independent and two vacancies as of early September 2026, leaving roughly eight weeks until the November midterms. Trader consensus at 98.7% on "No" reflects the limited remaining calendar for special elections, most of which are in districts unlikely to produce the net Democratic gains needed to reach 218 seats. Recent special election outcomes have preserved the balance without triggering a shift, and historical patterns show mid-session majority changes are rare absent multiple vacancies or resignations. The short timeline reduces exposure to unexpected events such as deaths, retirements, or procedural vacancies that could open additional contests. Even so, a cluster of rapid vacancies in competitive districts followed by Democratic special election wins could still alter the seat count before polls open on November 3.
