Jerry Carl holds a clear edge in trader consensus for the Alabama 1st District Republican primary nomination, reflecting his first-place finish in the May 19 primary results and established name recognition from prior service in the seat. State Representative Rhett Marques trails as the main challenger after placing second in those tallies, bolstered by stronger fundraising in late 2025 and an early endorsement from Senator Katie Britt, though recent polling showed the pair remaining closely competitive among likely voters. Court rulings on congressional map litigation have revived the May primary outcomes and scheduled a June 16 runoff between the two, limiting prospects for the remaining lower-polling candidates including Austin Sidwell, James Dees, Joshua McKee, James Richardson, and John Mills. These developments anchor the current implied probabilities ahead of the decisive vote.
