UFC 200 reportedly popped between 1.1 and 1.2 million PPV buys, according to Dave Meltzer, editor of the Wrestling Observer.
The UFC does not release PPV buy numbers, but Meltzer often projects the number based on his sources.
"It's a little lower than I expected," Meltzer said on his subscription-based radio show.
Meltzer said the buzz around the show was unexpectedly lower than anticipated.
"The bar population was not at the level of a Ronda Rousey or at the level of a Conor McGregor fight," said Meltzer, stating that high-level bar interest usually correlates to large PPV buy numbers. "It was not record-breaking numbers."
The UFC signed Brock Lesnar to appear at UFC 200 to help boost PPV buys. The show was marketed as the company's biggest event ever. Lesnar, arguably the biggest draw in the sport, fought at UFC 100, in a show that drew the company's highest PPV buy rate -- 1.6 million buys.
Lesnar reportedly earned $2.5 million for the show, plus a percentage of PPV buys. UFC 200, however, is still reeling from two high-profile reported USADA drug test failures involving Jon Jones and Brock Lesnar. Jones was flagged for a possible violation prior to the show and was pulled from the fight, while Lesnar was flagged for a possible violation late last week, after he defeated Mark Hunt by unanimous decision.
