Oklahoma's solidly Republican partisan composition and electoral history drive trader consensus toward a Republican victory in the 2026 Senate contest at 92.5 percent implied probability. The seat opened after incumbent Markwayne Mullin resigned in March 2026 upon confirmation as secretary of homeland security, with Alan Armstrong appointed as interim senator. Nonpartisan ratings classify the race as solid or safe Republican ahead of the June 16 primaries. Republican candidates including Kevin Hern lead early polling, while Democratic primary contenders show limited visibility and fundraising. A Democratic win would require an unusually strong nominee, significant Republican primary divisions persisting into the general election, or turnout shifts far exceeding historical patterns in this reliably Republican state.

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 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.
