Republicans currently hold a narrow House majority of roughly 218-214 with one independent caucusing alongside them and a handful of vacancies, a margin that has fluctuated modestly through special elections and member changes since the start of the 119th Congress but has not crossed into Democratic control. With only weeks remaining until the November 2026 midterms, the compressed timeline limits opportunities for additional vacancies, resignations, or special election outcomes capable of producing a net shift of three or more seats. Trader consensus at 98.9% for no pre-midterm flip reflects this structural reality along with the absence of recent developments that would accelerate such a change. Realistic scenarios that could still alter the outcome include multiple unexpected Republican departures followed by Democratic victories in rapid special elections or court-ordered processes that tip the balance 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.
