Analysis

5d ago

This market shows extreme asymmetry with Republicans priced at just 7¢ despite PA-12 being a historically competitive district, generating an extraordinary 2416.7% implied yield on the Yes side versus only 13.7% on the No side. The zero 24-hour volume combined with $37,215 open interest and a tight 1¢ spread suggests illiquidity and potentially stale pricing, raising questions about whether this deep underpricing reflects genuine market consensus or simply thin trading. With 201 days to expiration and a Cliff Risk Index of 13, this market warrants caution—the extreme yield may indicate either a significant mispricing opportunity or hidden tail risks that aren't immediately apparent.

Resolution rules

This market will resolve according to the party of the candidate who wins the PA-12 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/).
