The Charlie Kirk memorial had an estimated viewership between 25 to 30 million people across various online platforms and television. Specific numbers include over 2 million views on Fox News' YouTube livestream, about 1.15 million views for the Associated Press on YouTube, 3.3 million views on Charlie Kirk's X (formerly Twitter) account, and 6.62 million views on the Charlie Kirk YouTube channel alone, totaling over 13 million from just these sources. Including cable TV and other platforms, the total likely doubled to over 25 million viewers. Turning Point USA claims even higher numbers, estimating over 100 million viewers in total across all livestreams and broadcasts, though this figure is not independently verified.

In person, the memorial attracted about 90,000 to 100,000 attendees at the venue and overflow locations, with some reports indicating up to 200,000 people registered or trying to attend.
