Oklahoma Senate Race 2026 — Live Prediction Market Odds
Oklahoma changed hands quietly — Markwayne Mullin left the seat, appointed Republican Alan Armstrong holds it as a caretaker, and Republican Kevin Hern is the nominee for the full term. None of that dents the math: the market prices a safe Republican hold in a state this red, with the Democratic side a deep tail. The contract functions as a red-state calibration anchor for the board rather than a live trade; the only real question was the Republican nomination, and that is settled.
