Mayweather vs. McGregor Box Office: Fight Is a Knockout Victory in Theaters

Saturday night's live broadcast of the boxing bout grossed almost as much as new martial arts pic 'Birth of the Dragon.'

Saturday night's super-fight between world boxing champ Floyd Mayweather Jr. and Irish MMA star Conor McGregor was a knockout victory in theaters, earning $2.6 million from 532 locations in North America locations to come in No. 8.

Earlier on Sunday, comScore showed the special event earned $2.4 million from 481 theaters, but the grosses were later revised upwards for the U.S. and Canada.

The result is one of the biggest victories ever for Fathom Events, which partnered with Mayweather Productions in beaming the boxing match into cinemas. In many theaters, the price of entry was north of $20.

The card began at 6 p.m. PT. Mayweather emerged the victor in the 10th round, bringing his record to a perfect 50-0.

The Mayweather-McGregor bout at the T-Mobile Arena in Las Vegas was also a huge draw on pay-per-view at $99.99 a pop, although Showtime has yet to announce viewership numbers. Following the match, Periscope began trending on social media after many began bragging that they had watched the event for free using the streaming app.

At the box office, the live broadcast of the fight in theaters scored the third-best showing of the day behind The Hitman's Bodyguard ($3.9 million) and Annabelle: Creation ($2.8 million), according to comScore.

The Mayweather-McGregor offering saw its biggest grosses in New York City, Los Angeles, Baltimore, Nashville, San Diego and Miami. Top-grossing theaters included the AMC Empire and Regal Union Square in New York City, and Regal LA Live and AMC Burbank in Los Angeles.

Despite showing in far fewer theaters, the match appears to have beat another fight-centric offering on the marquee over the weeked: martial arts pic Birth of the Dragon, from microbudget genre label BH Tilt and WWE Studios.

Birth of the Dragon grossed $2.6 million from 1,618 locations, according to comScore (final weekend numbers will be tallied on Monday). The film, directed by George Nolfi, is a fictionalized account of when Bruce Lee challenged kung fu master Wong Jack Man to a fight in the mid-1960s in San Francisco.

The Mayweather-McGregor showdown was the highlight of an overall dismal weekend at the domestic box office, with revenue tumbling 45 percent over the same frame last year. Summer revenue is now down more than 14 percent over 2016, while the year to date is down more than 5 percent.
