Kevin Hern commands 88% trader consensus to win the Oklahoma Republican U.S. Senate primary, fueled by his profile as a three-term congressman from Tulsa with top-tier fundraising exceeding $2 million early and alignment with GOP base priorities amid Sen. James Lankford's post-border bill vulnerability. Markwayne Mullin sits at 2.2% despite incumbency in the other Senate seat, as speculation of a cross-seat bid remains low. Rep. Stephanie Bice holds 1.9% on Oklahoma City-area strength, while challengers like Ron Meinhardt and Tammy Swearengin share slim odds in a diffuse field. Recent catalysts include Hern's exploratory committee signals and internal polls favoring him over Lankford, with filing deadlines looming in April 2026.
