‘The Notorious’ Conor McGregor and undefeated boxer Floyd Mayweather are expected to lock horns at around 5am on Sunday morning.
But tickets on the resale market have failed to sell so far with prices ranging from $10,000 (£7,749) to $500 (£387).
And T-Mobile Arena general manager Dan Quinn has admitted that he is not quite sure why they have not reached the heights.
However, he has outlined the high ticket prices and all the different things that go into a fight could have a determining factor on why seats are still available.
“Every event is its own machine in terms of marketing and demand,” Quinn said.
“There’s just so many factors that go into it. Us in the arena world, we’re always amazed that when we book any event on the ones that are home runs right off the bat and the ones that we think are gonna do great, we don’t quite get there.
“There’s just so many variables in place. It’s tough to isolate any one if you have an event that doesn’t sell through all the tickets.”
He told MMA Fighting: “The ticket prices were ultimately the same as Mayweather-Pacquiao. There’s just so many factors, whether it’s time of the year or what people are doing in terms of travel, you just never know what’s gonna ultimately drive ticket sales for any given event. So, it’s tough to isolate anything, for any event that doesn’t sell out, honestly.”
UFC chief Dana White outlined on Thursday that the gate was at $70million (£54.5m), which is just shy of the combat sports record of $72m set by Mayweather vs Pacquiao.
But Quinn has not ruled out Conor McGregor v Floyd Mayweather eclipsing the record gate they set at the MGM Grand Arena in Nevada in 2015.
“It certainly has a chance,” Quinn said. “If Dana said we’re right at $70 million, we’re right on the cusp of it.
“So if we’re able to generate any kind of walk up — certainly there’s a ton of buzz in the city, we saw that [Friday] in the area for the weigh-in — if we’re that close, I would think that we would do enough walkup business to potentially eclipse that number.”
However, he did go onto say that nothing can be taking away from McGregor-Mayweather if they fail to break Mayweather-Pacquiao’s record gate.
He added: “Even in the event that they don’t eclipse the [record gate] number set by Mayweather-Pacquiao, it’s hard to call an event that’s potentially the second-highest grossing combat sports event ever a failure by any stretch of the imagination”.
