Analysis

5d ago

The market is pricing Republicans as heavy favorites at 83% to retain TX-10, but the extreme 888% implied yield on the "No" side signals severe illiquidity with only $12.4k open interest and zero 24-hour volume. The 2% price decline over seven days (85¢ to 83¢) is modest, though the high cliff risk index of 5 and 201-day timeline to the 2026 midterms suggest significant uncertainty could emerge as the election approaches and candidate fields solidify.

Resolution rules

This market will resolve according to the party of the candidate who wins the TX-10 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/).
