The memorial for Charlie Kirk was held at State Farm Stadium in Glendale, Arizona. This stadium, home to the NFL's Arizona Cardinals, has a seating capacity of around 63,400 which can be expanded for large events. The memorial took place on Sunday, September 21, 2025, and drew a massive crowd, hitting full capacity with tens of thousands of attendees inside and thousands more in overflow areas like the nearby Desert Diamond Arena. President Donald Trump, Vice President JD Vance, and many other political figures attended and spoke at the service to honor Kirk's legacy.
