Will the Democrats win the Colorado Senate race in 2026?

The market is pricing in an extremely high probability (91%) for a Democratic Senate win in Colorado, yet the No side offers a striking 1846% implied yield compared to just 18.1% for Yes, suggesting severe mispricing or illiquidity on the No contract. With only $206.68 in 24-hour volume against $31,794 open interest and a 10 Cliff Risk Index, the market appears illiquid and potentially unstable, particularly given the 56% realized volatility and recent 2-cent price decline from 93¢. The asymmetric yield structure and thin spreads indicate this market may be driven more by structural imbalances than fundamental conviction about the 2026 race outcome.

Resolution rules

This market will resolve according to the winner of the 2026 midterm Colorado 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.
