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 The Wrestling Observer Radio Show about UFC 168:
“It’s between 1 and 1.1 million… The late buys haven’t been counted, and there’s always going to be lag in recording, things like that, so it’s probably going to end up 1.1 million.”
