Primary elections in Iowa are scheduled to be held on June 2, 2026. This market will resolve according to the margin of victory between the top two candidates in the Iowa Democratic Senate Primary. The “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first-place 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. If the reported value falls exactly between two brackets, then this market will resolve to the higher margin bracket. If two candidates receive the exact same highest number of valid votes and both are listed, this market will resolve to the lowest bracket for the tied candidate whose last name comes first alphabetically. If only one of the tied candidates is listed, this market will resolve to the lowest bracket for that listed candidate. If neither tied candidate is listed, this market will resolve to “Other.” This market will resolve based on the official vote count once the count has been made official. If the results of the specified election are not known definitively by November 30, 2026, 11:59 PM ET, this market will resolve to “Other”. The primary resolution source for this market will be information from the State of Iowa, such as official statewide results published by the Iowa Secretary of State (https://sos.iowa.gov/); however, an overwhelming consensus of credible reporting may suffice. If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official.Turek secured the Iowa Democratic Senate nomination on June 2 with 62.6% of the vote to Wahls’s 37.4%, producing a 25-point margin that aligns with the market’s dominant 20–30% outcome. Pre-primary polling from multiple firms showed Turek maintaining double-digit leads throughout the spring, driven by endorsements from establishment senators and groups emphasizing his record as a state representative and Paralympian. Wahls, positioned as the more progressive challenger, failed to close the gap in a low-turnout contest. Final certification or minor adjustments remain the only realistic paths to any shift in the settled results.
