Lennox Lewis: $140 Million
Upon retiring from boxing in 2003, Lennox Lewis departed as a three-time heavyweight champion. His victory over Vitali Klitschko earned him $7 million, though it paled compared to the $17.5 million he garnered from his 2002 bout against Mike Tyson. The Tyson fight generated $106.9 million from nearly 2 million purchases in the United States. Lewis recorded 41 wins in 44 professional fights, with 32 by knockout.
