Will John Thune be the next Senate Majority Leader?

John Thune's odds have collapsed dramatically, falling from 36¢ to 20¢ over seven days, suggesting significant negative information arrival at a rate of 1.8 events per hour despite zero 24-hour volume. The 564.5% implied yield on the "Yes" side paired with extreme realized volatility of 847% and a wide 11¢ spread indicates this is a highly illiquid, speculative position with substantial cliff risk (index of 4), making the low price potentially unreliable for fair value estimation. With 259 days until resolution and only $3.65k open interest, this market lacks the depth to confidently price Thune's actual probability of becoming Senate Majority Leader.

Resolution rules

This market will resolve according to the individual who is announced as the next Senate Majority Leader after the November 3, 2026, U.S. General Election. This market will remain open until January 3, 2027, at which point it will resolve based on the first announcement of the next Senate Majority Leader from whichever party holds the majority in the U.S. Senate. If no Majority is established and a leader is not announced by June 30, 2027, 11:59 PM ET, this market will resolve to “Other”.
