Wrestlemania 28 is expected to be the first ever $8.5 million gate in pro wrestling history. The No. 2 pro wrestling event of all time was a $7 million gate back on April 4, 1998 at the Tokyo Dome for Antonio Inoki’s retirement match against Don Frye. Wrestlemania 27 in Atlanta was WWE’s second largest gate in history at $6,268,391.
