Which is why Conor McGregor's UFC boss Dana White was sounding off about exploitation when it was mistakenly reported that the Arena sold out within hours of the box office opening a week ago.
To put the sales into perspective, 800 tickets equates to four per cent of capacity. That means that despite the exorbitant pricing, 19,200 of the 20,000 places have gone already.
So like it or not, speculation that there could be a financial shortfall in this hybrid fight between Money Mayweather the boxing legend and Notorious McGregor the mixed martial arts star, is currently unfounded.
August 26 will see the shattering of the $50million-plus record for gate revenue for a boxing match, set when Mayweather fought Manny Pacquiao two years ago.
With pay-per-view subscriptions in the US set at five cents short of $100, cinemas across America set to charge sixty bucks a head for the closed-circuit transmission and foreign broadcasting rights fees set high, the first billion-dollar fight is on track.
So like them or not, Mayweather's projected $200m purse and McGregor's probable $100m seem assured.
All of which begs the question the world is reluctant to ask: Once this contrived cross-match is done and dusted, will Mayweather go back into retirement and McGregor return to the UFC? Or will there be a rematch? Perhaps under MMA rules?
That, one fancies, will depend on the financial projections. As Mr Mayweather never fails to remind us, money talks.
