These updated numbers include late recorded buys and have WrestleMania 28 doing 1,253,000 buys – 733,000 domestic and 520,000 internationally. The international number would beat the all-time record by a significant amount. There have been several events over the years that have topped the domestic number.
The 1,253,000 buys for WrestleMania 28 beats out the 1,250,000 buys for WrestleMania 23 in 2007 with Donald Trump. Technically, when it’s all said and done WWE is able to round up to 1.3 million buys and claim the biggest pay-per-view of all-time.
