Recent polling in Texas and Iowa, showing margins of just a few points between candidates like Paxton-Talarico and Hinson-Turek, has driven trader consensus toward these states as the likeliest closest 2026 Senate races. Competitive dynamics in Ohio's special election, Alaska, and Maine reflect similar factors, including strong challengers facing Republican-held seats, open Democratic seats in Michigan, and shifting state-level turnout patterns. These elements sustain tight implied probabilities across multiple battlegrounds. Further polling releases, candidate debates, fundraising disclosures, or national events could widen or narrow margins before November, potentially shifting focus among the leading contests.

This market will resolve according to the US Senate race which has the smallest margin of victory.
For the purpose of this market, the “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first- and second-place candidates. Percentages of the valid votes received by each candidate will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election.
For elections that include runoffs, ranked-choice, or other multi-round elections, the relevant margin of victory will be that of the round in which the winner is determined.
If two state margins of victory are identical, this market will resolve to the tied state whose last name comes first alphabetically.
This market will consider the results of all Senate elections, including special elections, that are scheduled to be held in November, 2026, by October 31, 2026, including the results of runoff elections held after November, 2026.
The resolution source for this market will be a compilation of all of the relevant state election authorities responsible for certifying statewide elections, however, a consensus of credible reporting may also be used.
