Kevin Hern secured the Republican nomination for Oklahoma’s open U.S. Senate seat after winning the June 2026 primary with nearly 70 percent of the vote, backed by President Trump’s early endorsement following Markwayne Mullin’s resignation to join the Cabinet. Oklahoma has not elected a Democratic senator since 1990, and the state’s consistent Republican margins in federal contests underpin trader consensus favoring Hern. Democratic nominee N’Kiyla Jasmine Thomas, a nurse who prevailed in the August runoff, enters the November general election with minimal campaign funds and limited statewide profile. Structural factors including partisan registration, historical turnout patterns, and Hern’s fundraising edge sustain the wide gap, though an unforeseen late development such as a major scandal or health event could still alter the outcome before Election Day.

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.
