Recent polling and analyst ratings point to roughly nine 2026 Senate contests as competitive enough to finish within a few points, centered on open or vulnerable seats in North Carolina, Michigan, Maine, Ohio, Alaska, Texas, and Iowa. Retirements by incumbents such as Thom Tillis and Gary Peters, combined with primaries that produced nominees like Roy Cooper, Abdul El-Sayed, and Michael Whatley, have kept these races fluid. National generic-ballot trends and state-level economic sentiment have narrowed margins in several Republican-held states, while Democratic efforts to defend Michigan and hold other seats add uncertainty. With the November 3 election less than two months away, late-campaign developments in voter turnout, candidate debates, and any shifts in the broader political environment could determine which specific races stay inside the 5 percent threshold.

This market will resolve to "Yes" if the specified 2026 Senate race has a margin of victory of 5% or less. Otherwise, this market will resolve to "No".
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.
The resolution source for this market will be the state election authority of the specified state, however, a consensus of credible reporting may also be used.
