Analysis
The market is pricing in a heavily favored Republican outcome at 85¢ with minimal trading activity ($0 in 24h volume), suggesting limited liquidity despite $12.5M open interest. The extreme implied yield asymmetry—32.2% for Yes versus 1034.1% for No—indicates the No position offers outsized returns but faces severe cliff risk (index of 6), reflecting the market's conviction that Republican victory is nearly certain. With 200 days to expiration and a tight 1¢ spread, this appears to be a relatively settled market with little recent price discovery, though the massive yield differential on the underdog position warrants caution about potential late-stage volatility or resolution ambiguity.
Resolution rules
This market will resolve according to the party of the candidate who wins the AZ-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/).
