The memorial service for Charlie Kirk reached full capacity at State Farm Stadium in Glendale, Arizona, which holds about 73,000 people for major events. Additionally, there was overflow space at a nearby venue, the Desert Diamond Arena, accommodating around 20,000 more attendees. Officials estimated that at least 200,000 people registered and showed up for the event, although the stadium itself was filled within hours, and some attendees were turned away due to capacity limits. Thus, the total number of people at the memorial, including the overflow, was approximately 200,000.
