It has been estimated that over 13 million people around the world have tuned into unauthorised outlets to watch the fight between Anthony Joshua and Andy Ruiz Jr last weekend, according to MUSO.

The piracy company has claimed that the UK racked up 921,994 unlicensed viewers, while Nigeria topped the list with 2.35 million.

“We saw how popular the Fury v Wilder fight was across piracy networks,” said Muso’s chief executive and co-founder, Andy Chatterley.

“The Joshua v Ruiz fight has been the largest unauthorised audience that we’ve ever tracked across boxing and it’s staggering to see that 93% of the audience watched via YouTube.

“The official pay-per-view audience figures have yet to be published, but this is a massive audience that’s being ignored.

“This highly engaged audience offers up huge insight and perhaps, more importantly, significant commercial opportunity.”

The figures are the highest recorded by MUSO since the company began monitoring figures for boxing in 2017. Unauthorised figures for the Joshua-Ruiz fight are considerably higher than the 9.98 million total for the Tyson FuryDeontay Wilder fight in December.

The UK is third on the list of audiences by country behind Kenya (998,027), with 93% of the worldwide audience using YouTube.
