This market will resolve according to the total number of valid votes cast in the 2026 midterm election for Senator from South Dakota. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. If the results of the specified election are not definitively known by March 31, 2027, 11:59 PM ET, this market will resolve to the lowest range bracket. All votes certified for candidates or non-candidate options in the specified election are included. Invalidated or blank votes are not included. In ranked-choice or preferential systems, the first-round vote total will be used. The primary resolution source for this market will be the official results of the 2026 midterm election for Senator from South Dakota, as published by the state electoral authority responsible for certifying the results of the election; however, an overwhelming consensus of credible reporting may also be used.In the low-salience 2026 South Dakota U.S. Senate contest, incumbent Republican Mike Rounds faces independent challenger Brian Bengs after the Democratic nominee withdrew in August, limiting voter mobilization and keeping the race noncompetitive. Historical midterm turnout in the state has ranged from roughly 350,000 to 355,000 ballots in 2022, well below presidential-year levels near 430,000, while the July primary drew just 118,000 votes amid typical off-year dynamics. With few high-profile issues or campaign events to drive engagement, registered-voter participation is expected to settle in a narrow band around recent midterm baselines. The closely matched market prices across multiple turnout buckets reflect this uncertainty over baseline participation rates and any late-cycle factors such as weather or targeted get-out-the-vote efforts that could modestly shift totals.
