Brock Lesnar earned $2.5million (1.9m) in his unanimous decision win over Mark Hunt at UFC 200.
The former heavyweight champion topped the list of earners at the event, according to figures released by the Nevada State Athletic Commission.
The 39-year-old earned more than three times the amount Hunt did for his comeback bout in Las Vergas after he triumphed 29-27 on all three judges’ cards.
Amanda Nunes made just $100k (£75m) for her upset victory over champion Miesha Tate, who pocketed $500k (£376k) despite defeat.
Daniel Cormier earned $500k for his victory over against Anderson Silva, who made $600,000.
