WWE announced that WrestleMania 33 grossed $14.5 million in ticket sales with a claimed attendance amount of 75,245 fans (though the numbers WWE claims often end up being untrue).
That makes it the second highest grossing (adjusted for inflation) wrestling event ever, only behind WrestleMania 32, which grossed $17.3 million. WrestleMania 32 had a much higher claimed attendance with 101,763 fans at AT&T Stadium in Arlington, TX. WrestleMania 33 ticket prices were higher, however.
