This market will resolve according to the winner of the 2026 midterm Iowa U.S. Senate election, inclusive of any run-offs. A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date. Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.Trader consensus prices a Republican victory at 60% in the open Iowa U.S. Senate race, reflecting the state's consistent GOP lean—Trump carried it by double digits in 2024—despite mixed recent polls showing Rep. Ashley Hinson either edging or trailing Democratic primary contenders Josh Turek and Zach Wahls. An April 9 Echelon Insights survey had Turek and Wahls up by 1-2 points over Hinson among likely voters, while earlier March polls from GBAO and internals favored Hinson by 4 points; these tight matchups underscore the race's competitiveness ahead of June 2 primaries. Hinson benefits from Trump, Tom Cotton, and Senate GOP leadership endorsements, bolstering her amid Democrats' early fundraising edge and March 24 VoteVets super PAC support for Turek. Historical polling discounts in Iowa further anchor GOP positioning.
