This market will resolve according to the winner of the Democratic Primary for United States Senator from Iowa. If no 2026 Iowa Democratic Senate Primary takes place, this market will resolve to "Other". The resolution source for this market will be the first announcement of the results from the Iowa Democratic party, however an overwhelming consensus of credible reporting may suffice.Josh Turek leads trader consensus at 67% implied probability for the Iowa Democratic U.S. Senate primary on June 2, driven by recent polls like PPP's May 6 survey showing him at 53% over Zach Wahls's 27%, bolstered by high-profile endorsements from former Sen. Tom Harkin on May 8 and Pete Buttigieg on May 13, alongside VoteVets' heavy spending. Turek, a state representative and Paralympic gold medalist, emphasizes his record beating Republicans, appealing to voters prioritizing general election viability against likely GOP nominee Rep. Ashley Hinson in the open seat race following Joni Ernst's retirement. Wahls, state senate minority leader alum, holds 23% amid early voting underway, but trails amid Turek's fundraising and momentum surge. Upcoming debates could shift dynamics in this closely watched primary.
