Kyle Sweetser leads trader consensus at 59.5% implied probability for the Alabama Democratic U.S. Senate primary on May 19, 2026, reflecting his early bipartisan endorsements from state Democratic legislative leaders and three former Republican lawmakers, which bolster his appeal in a low-turnout contest. Dakarai Larriett follows at 30.5%, supported by his entrepreneur profile and prior campaign momentum, including fundraising coordination with Democratic groups. Mark Wheeler and Lamont Lavender trail with 6.1% and 3.7%, respectively, amid limited visibility. Absent public polls or major developments in the past 30 days, markets hinge on perceived name recognition, final pre-primary fundraising reports due soon, and consolidation among sparse Democratic primary voters; a runoff looms if no candidate exceeds 50%.
