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 a commanding lead in the Delaware Republican U.S. Senate primary as the party-endorsed candidate with backing from state legislators, the former U.S. attorney, and multiple Republican organizations. His prior service as a state senator, combined with business and medical experience, has helped consolidate support among primary voters in a state where Republicans have not won a Senate seat since 1994. John Shulli, a military veteran and instructor at the U.S. Army War College, has emphasized national security and energy policy but trails significantly in organizational support. With the September 15 primary just days away, the outcome hinges on turnout in this closed primary; a surge in participation among Shulli’s base or any last-minute developments could narrow the margin, though the current trader consensus reflects Katz’s structural advantages.
