Republicans hold a razor-thin House majority of around 220-215 seats following the 2024 elections, making them highly vulnerable to losses in the 2026 midterms, where the president's party historically sheds an average of 26 seats amid lower turnout and backlash against the administration. Trader consensus prices Democrats at 83.5% implied probability to flip control, driven by early generic ballot polls showing Democratic leads of 3-5 points, intra-GOP divisions exposed in the recent narrow reelection of Speaker Mike Johnson (218-215 vote on January 3), and announcements of several Republican retirements in competitive districts. Upcoming special elections and redistricting challenges in battleground states like Pennsylvania and Michigan could further test Republican defenses before November 2026.
