There's heavyweight boxing and there's heavyweight boxing. Anthony Joshua's huge bout against Wladimir Klitschko is definitely the latter.
To be fought in front of a 90,000 sellout crowd at Wembley very, very soon, this fight will break all sorts of records.
The figures being thrown around are ludicrous. This fight is a real money-spinner.
Joshua himself is set to pocket a sweet £15 million from the fight, which is expected to break the British pay-per-view record, which dates as far back as 2007, when Ricky Hatton lost to Floyd Mayweather Jnr.
Hatton's fight brought in 1.2 million pay-per-view viewers, whereas Joshua's bout is expected to attract an audience of 1.5 million, paying £19.99 each for the privilege to watch the fight live.
This alone would bring in a revenue of nearly £30 million, with the fight expected to bring in a monumental £50 million across all avenues - making it the richest fight in UK history.
Gate revenues alone at Wembley will account for around £8 million.
This is just in the UK.
This fight has attracted world interest, with German TV station RTL paying around £4 million to show the fight live. This, along with broadcast rights in the USA and TV rights across the world, raising another £3 million.
And who could forget the sponsorship and merchandising deals?
In short, Joshua's fight against Klitschko is going to be absolutely huge. A lot, lot bigger than David Haye's fight against Tony Bellew just last month, which attracted a pay-per-view audience of 890,000.
Both camps are understandably massively excited by the figures being thrown around. Perhaps none more so than promoter Eddie Hearn.
He has said: “Of course there is a lot of money at stake.
“With all these things, you can do the maths.
“I don’t like breaking it down to figures — but you know the pay-per-view price and you know the capacity of Wembley."
Hearn doesn't think that the numbers being thrown around will be in Joshua's or Klitschko's minds, however, and that they will both fight without the nerves that one might expect at an event as big as this.
“Anthony and Wladimir know the levels of income that could be achieved — but I don’t think it’s in their minds."
Alongside Joshua and Klitschko, the fight officials have been decided.
David Fields will referee, whilst the judges take the form of Don Trella, Nelson Vazquez, and Steve Wiesfeld.
Freddie Roach, trainer of Scott Quigg, is expecting Joshua to beat Klitschko despite his friendship with the latter.
“I’m going to go with youth, even though Klitschko is my friend. He will be mad at me — but I think youth should prevail."
Who do you think will walk away from this £50 million mega-fight victorious? Youth with Joshua? Or Klitschko's experience? Tell us in the comments.
