Analysis

5d ago

The Republican contract is priced at an extreme 5¢ with a staggering 3,467% implied yield, reflecting the heavily Democratic lean of CA-34, though the 2¢ spread and modest $15.92 daily volume suggest thin liquidity that could amplify price swings. With 200 days to expiration and a Cliff Risk Index of 19, there's meaningful uncertainty embedded despite the low baseline probability, indicating traders see non-trivial tail risk for a Republican upset. The neutral regime score (0.409) and flat 7-day price action suggest the market has settled into a consensus view, but the asymmetric yield profile between Yes (3,467%) and No (9.6%) highlights the speculative nature of betting on a Republican breakthrough in this district.

Resolution rules

This market will resolve according to the party of the candidate who wins the CA-34 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/).
