Analysis

4d ago

This market displays extreme mispricing with the Republican contract trading at just 8¢ despite CO-07 being a competitive district, generating an extraordinary 2099.6% implied yield on the Yes side versus only 15.9% on the No side. The zero 24-hour volume combined with $15,464 open interest and a tight 1¢ spread suggests illiquidity is preventing price discovery, likely leaving this contract significantly undervalued relative to fundamental political probabilities. With 200 days to expiration and a Cliff Risk Index of 12, the market appears to be pricing in near-certain Democratic retention, which warrants skepticism given the district's historical competitiveness and the substantial time remaining for political conditions to shift.

Resolution rules

This market will resolve according to the party of the candidate who wins the CO-07 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/).
