Republican nominee Chris Gober's outright primary win on March 3 with 51% of the vote, following incumbent Michael McCaul's 2025 retirement announcement, has solidified trader consensus at 83% implied probability for a Republican hold in the Solid Republican-rated Texas 10th Congressional District, where McCaul previously won by nearly 30 points. Democrat Caitlin Rourk advanced from the May runoff to become the nominee, sustaining 50% odds amid an open seat that drew heavy primary spending exceeding $6 million per recent FEC reports. Absent polls, the district's GOP lean in suburban Austin-to-East Texas counties and historical base rates for safe seats underpin the positioning, though national midterm dynamics or candidate scandals could shift probabilities ahead of the November 3 general election.
