Trader consensus prices a commanding 93% probability on a Republican victory in Wyoming's open U.S. Senate race, driven by the state's entrenched Republican dominance—GOP candidates have won every Senate contest since 1976 with double-digit margins, including 44-point presidential victories in 2020 and 2024. Incumbent Sen. Cynthia Lummis's December 2025 retirement opened the seat, but Rep. Harriet Hageman dominates the GOP primary field with endorsements from President Trump and Sens. John Barrasso and Lummis; recent entrants Sam Mead and Jimmy Skovgard (announced April 27) pose limited threats ahead of the August 18 primary. Democrats field weak opposition, lacking competitive polling or fundraising. Upsets would require GOP nominee scandal, primary bloodbath, or national Democratic wave, though base rates favor Republican holds in deep-red states.
