This market will resolve according to the candidate who wins the nomination for the Republican Party to contest the AZ-05 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Republican primary will take place on August 4, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Republican sources, including https://www.rnc.org/. Any replacement of the nominee before election day will not change the resolution of the market.Former Pinal County Sheriff Mark Lamb dominates trader consensus at 88% implied probability to win Arizona's 5th Congressional District Republican primary on July 21, fueled by a December 2025 Victory Insights poll showing him ahead by 60 points among likely GOP primary voters and President Trump's November 2025 endorsement, which boosted his name recognition in the open seat race following incumbent Andy Biggs' departure. State Representative Travis Grantham and former NFL kicker Jay Feely trail at 5.7% and 5.3%, respectively, lacking comparable polling strength or high-profile backing despite recent signature filings to secure ballot access in late February. With the filing deadline passed on April 6, upcoming debates and early GOP turnout patterns could influence the closely watched contest in this deep-red district.
