Will the Republicans win the Oklahoma Senate race in 2026?

The market is pricing in an extremely high probability (93%) for Republican victory in Oklahoma's 2026 Senate race, reflecting the state's deep red lean, though the zero 24-hour volume suggests minimal recent trading activity and potential liquidity concerns. The asymmetric implied yields—13.7% for Yes versus 2,425.6% for No—indicate severe mispricing on the No side, likely due to illiquidity rather than genuine market conviction, with a 1,213% risk-adjusted yield highlighting outsized tail risk. With nearly two years until resolution and a modest $17.6K open interest, this market lacks the depth to confidently validate the extreme price, and traders should be cautious of the 13-point Cliff Risk Index signaling potential resolution ambiguity.

Resolution rules

This market will resolve according to the winner of the 2026 midterm Oklahoma U.S. Senate election, inclusive of any run-offs. 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. 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.
