This market will resolve according to the winner of the Republican Primary for United States Senator from Delaware. If no 2026 Delaware Republican 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 Delaware Republican party, however an overwhelming consensus of credible reporting may suffice.Michael Katz holds an 88% implied probability in trader consensus for the Delaware Republican Senate primary, driven by his endorsements from the state Republican Party, the Independent Party of Delaware, former U.S. Attorney Julianne Murray, and multiple state legislators. As a former Democratic state senator, physician, and business owner who previously ran as an independent, Katz has built a broad coalition appealing to primary voters in the closed September 15 contest. John Shulli, a retired Army colonel and War College instructor endorsed by Michael Flynn, maintains a narrower base of support focused on military and defense credentials. With the primary days away, limited public polling and fundraising patterns have reinforced Katz’s lead in this low-turnout race.
