About This Event

This market will resolve according to the total number of valid votes cast in the 2026 midterm election for Senator from Illinois. 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 Illinois, 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.
