Incumbent Democrat Nikki Budzinski faces Republican Jeff Wilson in Illinois’s 13th congressional district on November 3, 2026. Forecasters rate the seat solid or safe Democratic, reflecting the district’s partisan lean, Budzinski’s incumbency, and her substantial fundraising edge of roughly $3.7 million raised versus Wilson’s $532,000. Primaries concluded in March without altering the general-election matchup. Absent public polling or major recent catalysts such as debates or endorsements, trader pricing on margin outcomes centers on a Democrat win of 25-30 points as the most probable result, with lower probabilities assigned to both narrower and wider margins. The low price on a Republican victory aligns with the district’s structural and resource dynamics.
