Analysis
This market shows extreme conviction in Republican dominance of South Dakota's at-large House seat, with a 92¢ price reflecting a 92% win probability, though the $0 24-hour volume and $24.8K open interest suggest minimal recent trading activity and potential liquidity constraints. The massive 2091.8% implied yield on the "No" side is a classic indicator of a deeply lopsided market where contrarian positions are severely underpriced, creating asymmetric risk that may not reflect true Democratic chances in this reliably Republican state. With 201 days to expiry and a moderate 12 Cliff Risk Index, the market has time for repricing, but the 1¢ spread and neutral regime suggest this reflects genuine political fundamentals rather than technical distortion.
Resolution rules
This market will resolve according to the party of the candidate who wins the SD-AL 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/).
