About this market
Democrats hold an 88.5% implied probability of winning House control in the November 2026 midterms, reflecting the opposition party's typical midterm advantage during a president's term. Generic congressional ballot averages show Democrats ahead by roughly 6–7 points, consistent with polling trends since early 2025 and reinforced by recent special election results. Forecasters cite low presidential approval ratings, economic concerns including tariffs, and a national environment that has shifted race ratings toward Democratic-leaning outcomes in multiple competitive districts. While mid-decade redistricting provided Republicans some structural gains, the current polling edge and historical patterns position Democrats to overcome the narrow 2024 majority and reach the 218-seat threshold in most simulations.
