WWE announced during SummerSlam last Saturday that the attendance was 51,326.
However, Dave Meltzer reported in the Wrestling Observer Newsletter that the actual attendance for the event was 45,690, with 41,000 paid.
WWE always marks up the number for marketing purposes. Allegiant Stadium can seat 65,000 for NFL and seats can be added on the floor.
The show’s gate was four times higher than Summerslam 2019, which drew 13,500 paid.
