As the home fighter and the headline name on the card, Joshua is set to pocket the majority of the fight purse.
Both fighters will receive a proportion of the revenue from pay-per-view TV sales, with the bout being shown live on Sky Sports Box Office.
Including sponsorship deals, pay-per-view revenue, Joshua is expected to earn close to £20m from the bout.
That sum could be significantly larger if, as expected, Joshua takes a fight with Wilder later this year.
Parker, on the other hand, is guaranteed £13m from the bout – significantly more than Joshua’s previous opponent, Carlos Takam, who pocketed an estimated £1 million from his defeat to AJ last October.
