GSP vs. Bisping pay-per-view estimates in for North America

Early estimates have UFC 217, the show on Nov. 4, headlined by George St-Pierre's welterweight title win over Michael Bisping as doing 875,000 pay-per-view buys in North America.The number would be the highest of the year, and best since the Amanda Nunes vs. Ronda Rousey fight on Dec. 30, 2016.
After the show, UFC President Dana White said that it was trending to blow past one million buys. The North American number would not include Australia, where the show did very well, nor pay-per-view buys
