Delaware Republicans are selecting their 2026 U.S. Senate nominee on September 15 to challenge incumbent Democrat Chris Coons, with Michael Katz holding an 86% implied probability in the primary market versus John Shulli at 12%. Katz, a physician and former Democratic state senator who later ran as an Independent in 2024 before switching parties, secured the Delaware Republican Party’s endorsement at its April convention with an 82% delegate vote and gained additional backing in July from former state party chair and U.S. Attorney Julianne Murray. Traders appear to view Katz’s prior elected experience, coalition-building emphasis, and crossover appeal as stronger assets in a heavily Democratic state. Shulli, a retired Army colonel and War College instructor, has positioned himself on issues including border security and government accountability but lacks comparable institutional support or name recognition to date.

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.
