Analysis

4d ago

The Democratic contract is pricing in a 93% win probability for CA-50, yet the market shows zero 24-hour volume with only $19,937 in open interest, suggesting minimal liquidity and potentially stale pricing. The extreme 2424.5% implied yield on the "No" outcome is a classic illiquidity artifact reflecting the tiny remaining upside for Republican backers, though the 13-point Cliff Risk Index indicates meaningful tail risk that could materialize as the November 2026 election approaches. With 200 days to expiry and a tight 2¢ spread, this market appears to be pricing in a strong Democratic lean for the district but lacks the trading activity needed to validate whether 93¢ truly reflects consensus.

Resolution rules

This market will resolve according to the party of the candidate who wins the CA-50 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/).
