This market will resolve according to the party of the candidate who wins the TX-21 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/).Trader consensus favors the Republican Party at 80% implied probability to win Texas's 21st Congressional District House seat, reflecting the district's R+10 Cook Partisan Voting Index, consistent large GOP margins—such as 26 points in 2024 and 2022—and ratings as Solid or Safe Republican by Cook Political Report, Inside Elections, and Sabato's Crystal Ball. Incumbent Chip Roy vacated the open seat to pursue the Texas attorney general nomination, but former MLB star Mark Teixeira secured the GOP nod with 63% in the March 3 primary amid 12 contenders, bolstering his position with over $3.6 million raised versus Democrat Kristin Hook's $154,000; Hook, the repeat 2024 nominee who lost 36%-62%, won her primary 60%-28%. Absent national Democratic waves, no general election polls show competitiveness ahead of November balloting.
