Will Charles Booker be the Democratic nominee for Senate in Kentucky?

Charles Booker is priced at a dominant 86¢ on Polymarket with a 3¢ spread, but the 3-cent cross-venue gap to Kalshi (83¢) suggests some uncertainty about his nomination prospects despite the high implied probability. The extreme 7562% implied yield on "No" combined with 96% realized volatility and a Cliff Risk Index of 6 indicates this market is pricing in significant tail risk, likely reflecting the possibility of a late-breaking candidate entry or primary upset, though the 30-day window to resolution leaves limited time for major shifts. With only $25.92 in 24-hour volume against $14.4M open interest, liquidity is notably thin relative to positioning, which could amplify price swings if new information emerges.

Resolution rules

This market will resolve according to the winner of the Democratic Primary for United States Senator from Kentucky. If no 2026 Kentucky Democratic Senate Primary takes place, this market will resolve to "Other". The resolution source for this market will be the first announcement of the results from the Kentucky Democratic party, however an overwhelming consensus of credible reporting may suffice.
