Republicans hold a slim 217-214 House majority (including one independent caucusing with Democrats) amid four vacancies, as trader consensus prices "No" at 84% for losing control before the November 2026 midterms. The most recent development, Democrat Analilia Mejia's April 17 victory in New Jersey's 11th District special election, merely filled a Democratic vacancy left by Gov. Mikie Sherrill, leaving party balance unchanged. Earlier 2026 special elections and resignations like Marjorie Taylor Greene's narrowed the GOP edge but failed to flip it, with no major new vacancies or high-risk races scheduled. Record Republican retirements loom for the general election but do not trigger pre-midterm specials unless members resign early, reinforcing low flip probability per historical patterns of House control stability.

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.
