Anthony Joshua is all set to clear a guaranteed 13 million pounds or $37.05 million from his fight against Joseph Parker as long as Pay Per View numbers go as expected.
Joshua will add another £1m to £2 million pounds from sponsorship deals.
Joseph Parker is also expected to clear his career-best purse of around 7 million pounds or $19.95 million from this fight.
Meanwhile, former world champion Frank Bruno has warned Anthony Joshua from getting "macho" with Joseph Parker whom he rates highly.
56-year-old Bruno remains dear to British fight fans after winning the world title at his fourth attempt when he beat American Oliver McCall on points to claim the WBC belt in 1995.
He is hugely impressed by Joshua and sees him winning his world heavyweight unification fight against Parker in Cardiff on April 1st if he is sensible and uses a tactical game plan against a "very dangerous" opponent.
Bruno told Sky Sports that if Anthony Joshua moves around and uses his reach and his power, he should make it, not an easy fight, but make it easier for himself.
Bruno says if Joshua is going to get macho and start wanting to tear up with Parker, then Parker is a very dangerous guy, very fit, and he is on you all the time.
Bruno, who quickly lost his world title when he was knocked out by Mike Tyson, likes the way Joshua has become a people's champion in the UK.
Joshua's promoter Eddie Hearn told UK media that 77,000 seats had been sold for the fight at Cardiff's Principality Stadium which will have the roof closed.
The fight looks headed for a sellout with as many as 80,000 attending.
Parker puts his WBO belt on the line and Joshua is fronting with his WBA and IBF titles as the heavyweight division works towards having one true world champion.
