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 Delaware’s Republican U.S. Senate primary due to his endorsement by the state Republican Party, former U.S. Attorney Julianne Murray, and multiple state legislators, along with his prior service in the Delaware Senate and professional background as a physician and business owner. The closed primary on September 15 limits participation to registered Republicans, where Katz consolidated support after switching from the Independent Party and securing the nomination at the April state convention. John Shulli, a retired Army colonel and War College instructor emphasizing national security and energy policy, has raised competitive funds but trails in organizational backing. With the vote days away, late shifts would require unexpected developments such as major candidate withdrawals or last-minute scandals to alter the outcome.
