Analysis

4d ago

This market shows extreme illiquidity and pricing distortion typical of deeply one-sided prediction markets, with zero 24-hour volume despite $17,911 in open interest. The 95¢ price reflects overwhelming confidence in Republican victory in IL-15, though the massive 3,467% implied yield on the No side signals severe mispricing—likely due to minimal trading activity rather than genuine uncertainty. With 200 days to expiration and a cliff risk index of 19, this market carries elevated tail risk, suggesting traders should be cautious about the reliability of the 95% probability estimate given the illiquid conditions.

Resolution rules

This market will resolve according to the party of the candidate who wins the IL-15 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 4, 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/).
