Wyoming's open Senate seat, vacated by retiring Republican incumbent Cynthia Lummis, features Republican nominee Harriet Hageman against Democrat James W. Byrd following August 2026 primaries. Hageman's decisive primary win, Trump endorsement, substantial fundraising edge, and established profile as the state's sole House member have solidified her position in a state where Republicans have dominated recent statewide contests. Election forecasters across outlets rate the race as solid or safe Republican, aligning with trader consensus reflected in the current odds. Factors that could still shift outcomes include late-campaign developments such as major scandals, candidate health issues, or unexpected national political shifts in the weeks before the November 3 vote.

A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date.
Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party.
The candidates may be named in the contract for the convenience of traders. In the event that any named candidate is replaced as the nominee of their respective party prior to election day, the name in the contract will be updated and the market will resolve based on the replacement nominee of the party.
The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.
