Ongoing litigation over Missouri's newly redrawn congressional map remains the dominant factor in trader assessments for the MO-05 House race. The map, enacted after a 2025 special session, shifts the Kansas City-based district toward Republican territory by incorporating rural areas and splitting urban Democratic strongholds, positioning GOP nominee Rick Brattin as the favorite under current lines. However, appeals to the Missouri Supreme Court regarding a rejected referendum petition could restore the prior boundaries used in 2022 and 2024, which favored incumbent Democrat Emanuel Cleaver. With the November 3 general election approaching and no polls released since the August 4 primaries, market pricing reflects uncertainty around the map's final status and potential resolution timing as the primary driver of implied probabilities.
