Analysis
This market shows extreme illiquidity with zero 24-hour volume despite $27,866 in open interest, suggesting the 7¢ price may not reflect genuine market consensus but rather stale positioning. The 2416.8% implied yield on the Yes side is extraordinarily high and likely unrealistic, indicating the market is pricing in an extremely unlikely Republican victory in this heavily Democratic Massachusetts district—a 93% implied probability for Democrats is more consistent with historical voting patterns. With 201 days to expiration and a neutral regime score, this appears to be a thin, speculative market where the extreme odds and lack of recent trading activity warrant caution before treating the price as a reliable forecast.
Resolution rules
This market will resolve according to the party of the candidate who wins the MA-08 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/).
