This market will resolve according to the party of the candidate who wins the WI-03 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 3, 2026. ​​A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources. This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).Rebecca Cooke holds a substantial lead in trader consensus for the Wisconsin 3rd District House race, reflecting recent polling that shows her ahead by margins of 2 to 4 points in head-to-head matchups against incumbent Derrick Van Orden. Cooke secured the Democratic nomination in the August 11 primary with about 60 percent of the vote and has maintained a fundraising edge exceeding $8.6 million raised. The district, rated a toss-up by multiple forecasters and carrying an R+3 partisan lean, features a rematch of the 2024 contest that Van Orden won by under 3 points. Recent developments include competing ads on agricultural policy, tariffs, and data center regulation, alongside Cooke's clearance from electioneering inquiries and Van Orden's use of AI-generated content in campaigning. These factors, combined with the seat's status as a key battleground for House control, underpin the current implied probabilities.
