WWE has broken their legit all-time attendance record with WrestleMania 32. The event has sold over 84,000 tickets as of 3/8. If WWE wants to get over 90,000, then they would need to sell standing room tickets. AT&T Stadium has massive areas to have people stand so it’s very possible that they get 90,000.
Prior to WrestleMania 32, WWE broke their attendance record back in 1992 with 79,127 tickets for SummerSlam in London’s Wembley Stadium. That was the show headlined by The Ultimate Warrior vs. Randy Savage and “British Bulldog” Davey Boy Smith vs. Bret “The Hitman” Hart.
The 93,173 number for WrestleMania 3 is listed as their “entertainment purposes” number on internal documents, but the real attendance for that show was just over 78,000.
