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 Senate primary as the September 15 vote approaches, driven by endorsements from former state party chair and U.S. Attorney Julianne Murray, multiple Republican state legislators, and party organizations. His background as a former Democratic state senator, physician, and 2024 independent Senate candidate has helped him assemble a broader coalition in Delaware’s closed primary system. John Shulli, a retired Army colonel and instructor at the U.S. Army War College, has secured support from figures such as Michael Flynn and some legislators but trails in organizational backing and visibility. Trader consensus reflects these structural advantages for Katz. A sudden shift in turnout patterns or an unforeseen late development could still narrow the margin before primary day.
