Recent polling aggregates show multiple 2026 Senate contests clustered near even, driven by President Trump's net-negative approval ratings near 40% and several open seats. Texas, Alaska, Michigan, Ohio, New Hampshire, Maine, and Iowa currently register the tightest margins, with most within or just outside 5 points in late-summer surveys. Open Democratic retirements in Michigan and New Hampshire, combined with strong challengers such as Roy Cooper in North Carolina and competitive recruitment in farm states facing tariff and price pressures, have kept these races fluid. Republicans defend more seats overall, yet the national environment and candidate matchups have narrowed gaps in states that leaned Republican in 2024. Traders price these battlegrounds as the primary variables determining whether margins stay inside 5%, with the November 3 election serving as the resolution trigger.

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.
