Republicans currently hold a narrow House majority of roughly 218-214 seats heading into the final weeks before the November 2026 midterms. Trader consensus at 98.7% on “No” reflects the structural barriers to any pre-election flip: vacancies from deaths or resignations have occurred but have not produced a net Democratic gain sufficient to reach 218 seats, and special elections capable of shifting control remain rare in such a short window. Historical precedent shows mid-term control changes through these mechanisms are exceptionally uncommon. Realistic scenarios that could still move odds include clustered Republican vacancies in competitive districts followed by Democratic special-election victories, or procedural disruptions that prevent the chamber from organizing, though both would require multiple rapid, low-probability events before Election Day.

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.
