Tyler Robinson faces aggravated murder and related charges in Utah for the September 2025 shooting death of conservative activist Charlie Kirk, with prosecutors citing surveillance video, DNA evidence on the recovered rifle, and alleged admissions. A judge ruled in September 2026 that probable cause exists on all counts, binding the case over for trial after Robinson entered not guilty pleas. As of October 2026, however, no trial date has been set amid disputes over timelines, with the defense seeking a 2029 start due to case complexity and the prosecution proposing 2027 or early 2028. The Polymarket contract resolves on a conviction by mid-2027, so trader pricing at 89.5% for no conviction reflects the extended pretrial motions, capital-case procedures, and scheduling delays typical in such proceedings rather than assessments of evidentiary strength.
