Analysis

4d ago

PA-01 is pricing Democrats at 44¢ despite extremely high realized volatility of 690% and an exceptional 231% implied yield on the Yes side, suggesting significant uncertainty or potential mispricing in this deep red district. The market shows zero 24h volume with $14.6M open interest and an 8¢ spread, indicating illiquidity that may be masking true fair value, while the 6-point price rise over seven days (38¢ to 44¢) could reflect recent polling shifts or campaign developments worth investigating against historical district leanings. With 201 days to expiration and a neutral regime score, this market appears to be pricing in meaningful Democratic upside potential, though the lack of trading activity warrants caution about execution risk.

Resolution rules

This market will resolve according to the party of the candidate who wins the PA-01 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/).
