Michael Katz leads the Delaware Republican U.S. Senate primary with strong trader consensus due to his prior service as a state senator, medical and business background, and key endorsements including from former U.S. Attorney Julianne Murray and Republican legislators. These factors highlight his positioning as a candidate able to build coalitions in the heavily Democratic state ahead of the September 15 primary. John Shulli, a retired Army colonel and instructor at the U.S. Army War College, trails with emphasis on national security and energy policy but trails in institutional support. Recent campaign finance reports and candidate forums have reinforced Katz's edge without major shifts in the closing weeks.

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.
