Analysis

4d ago

The market is pricing an extremely lopsided outcome with Democrats at 93¢, yet the No side shows an anomalous 2425% implied yield—a red flag suggesting severe illiquidity and potential mispricing on the Republican side rather than genuine conviction in a Democratic win. With zero 24-hour volume despite $16K open interest and 200 days to expiration, this appears to be a stale or abandoned position, making the quoted prices unreliable for actual trading. The 1¢ spread and high cliff risk index (13) indicate thin liquidity that could produce sharp repricing if new information emerges about CA-30's competitive dynamics.

Resolution rules

This market will resolve according to the party of the candidate who wins the CA-30 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/).
