Tyson Fury: $20 Million
Although Tyson Fury has not stepped into the ring since claiming the WBA, IBF, WBO, IBO, The Ring, and lineal heavyweight titles from Wladimir Klitschko in 2015, he maintains an undefeated professional boxing record. The British boxer earned his first title belt in 2009 when he won the English heavyweight championship against John McDermott. While rumors circulate about Fury's potential return to the ring, no official fights have been confirmed. He vacated his title in 2016 following an anti-doping investigation.
