When it comes to PPV buy rates we never really get disclosed true and accurate figures. However the one reliable and lone source for UFC pay-per-view figures has and always will be, Mr. Dave Meltzer.
When people talk of buys, stating this PPV did this amount and this one did that, it is all based on his industry intelligence. The UFC never confirms figures, nor do the broadcasters, however, Meltzer’s time in the PPV business has gone on way before the UFC existed and therefore his estimates and contacts are widely considered as valid and on point.
With that being said, here is what he said via MMAFighting.com about UFC 167:
UFC 167, held on Nov. 16, where he defeated Johny Hendricks in what was the most talked about decision of the year, is currently estimated at doing 600,000 to 650,000 buys, a number significantly above what Manny Pacquiao vs. Brandon Rios did a week earlier. While not as big in the United States, the latter show reportedly set records for any type of pay-per-view in Eastern Canada, where St-Pierre is from, and also reportedly set a UFC record with more than 40,000 fans across the U.S. watching in movie theaters.
The number for the Hendricks fight would be a disappointment because it would be the lowest for a St-Pierre card since 2008.
Numbers for the pay-per-view industry as a whole have been below expectations since September, after the Floyd Mayweather Jr. vs. Canelo Alvarez show did an estimated 2.2 million buys, and set a revenue record, generating in excess of $150 million.
