Floyd Mayweather and Conor McGregor's money-spinning superfight failed to break the record for gate receipts at a Las Vegas boxing bout, figures released by the Nevada State Athletic Commission revealed Wednesday.

The controversial August 26 fight raked in $55,414,865.79, well short of the $72,198,500 generated by Mayweather's 2015 "Fight of the Century" against Manny Pacquiao at the MGM Grand.

The Mayweather-McGregor bout, staged at the T-Mobile Arena, sold 13,094 tickets, well short of the venue's 20,500 capacity. The Mayweather-Pacquiao fight sold 16,219 tickets.

A total of 137 complimentary tickets were given away for Mayweather-McGregor, won by Mayweather in a 10th-round technical knockout.

Face-value ticket prices for Mayweather-McGregor were among the most expensive in history, with cheapest seats going for $500 and the most expensive for as much as $10,000.

Although the fight failed to challenge the Mayweather-Pacquiao gate total, it becomes the second highest-grossing gate in Las Vegas history, surpassing the $20 million generated by Mayweather's 2013 defeat of Canelo Alvarez.

The bout is also set to be one of the richest fights in history if the most bullish predictions of pay-per-view television sales are met.

Some predictions have suggested the fight could threaten the 4.6 million buys generated by Pacquiao-Mayweather.

Official numbers have not been released although executives from cable network Showtime Sports said they expected the bout would at least be second.
