Republicans currently hold a narrow House majority ahead of the November 3 midterms, but recent polling shows Democrats leading the generic congressional ballot by roughly 7–9 points. Multiple forecasting models and race ratings, including shifts in the Cook Political Report, have moved additional competitive districts toward Democrats in the past week. Redistricting in several states has provided Republicans some structural advantages in targeted seats, yet these have not offset the national environment. Prediction markets reflect trader consensus on low odds for Republican retention, with Democratic control probabilities trading above 90 percent. Key factors that could still influence short-term movement in those implied probabilities include any late October polling releases or campaign spending shifts in toss-up districts.
