Several 2026 Senate contests remain highly competitive as Election Day approaches, with recent polling showing margins under 5 points in states including Maine, Michigan, Ohio, Texas, Alaska, and Iowa. Low presidential approval and midterm headwinds have narrowed gaps in Republican-held seats, while open Democratic seats in Michigan and Georgia draw strong challengers. Late-cycle factors such as candidate recruitment, turnout in swing areas, and any final polling shifts could determine which races finish within the threshold. Traders focus on these battlegrounds because small changes in voter preference or participation often decide outcomes in a chamber where control hinges on a handful of close results.

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.
