Analysis
This market shows extreme illiquidity with zero 24-hour volume despite $21k open interest, suggesting the 6¢ price may not reflect true consensus given the wide 2¢ spread and staggering 2860% implied yield on the Yes side. CA-43 is a heavily Democratic district (Cook PVI D+13), making a 6% Republican win probability appear overpriced, though the neutral regime score and flat price action over seven days indicate limited recent conviction either way. With 200 days to expiry and a Cliff Risk Index of 16, this market carries meaningful tail risk and would benefit from deeper liquidity to establish a more reliable price discovery mechanism.
Resolution rules
This market will resolve according to the party of the candidate who wins the CA-43 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/).
