The attendance at Charlie Kirk's funeral memorial service was very large and reportedly exceeded the main venue's capacity. The main service at State Farm Stadium in Glendale, Arizona, which has a capacity of about 63,000 to 73,000 people, was filled to capacity. Additionally, an overflow venue next to the stadium, Desert Diamond Arena, accommodated about 10,000 more people. Estimates vary, but roughly 90,000 to 100,000 people attended in person according to police estimates, while organizers said about 200,000 people registered or showed up, with many turned away due to capacity limits. Another large online viewership was reported for live streaming of the memorial service as well. In summary:

• State Farm Stadium capacity: 63,000 to 73,000 (filled to capacity)
• Overflow venue Desert Diamond Arena: about 10,000
• Police estimate: about 90,000 to 100,000 attendees
• Organizers' registration estimate: about 200,000 people showed up or registered
• Additional thousands watched via live streams

This makes the event one of the largest memorials for a private citizen in recent memory.
