Rebecca Cooke holds a strong lead in the Wisconsin 3rd Congressional District race, with traders assigning her a 72.5% implied probability compared to incumbent Derrick Van Orden’s 25.5%. The August 11 primaries clarified the matchup, as Cooke defeated a progressive challenger with roughly 60% of the vote while Van Orden ran unopposed. Recent polling shows Cooke ahead by small margins in a district that Trump carried by about 7 points in 2024 and where Van Orden won the prior cycle by under 3 points. The seat’s toss-up or lean-Democratic ratings from multiple forecasters, combined with Cooke’s fundraising edge and the broader midterm environment, have contributed to the current trader consensus favoring the challenger. The November 3 general election remains the resolution trigger.
