George Foreman: $300 Million
George Foreman, a boxing legend turned grilling magnate, engaged in the sport for 28 years. Although he experienced a loss to Muhammad Ali in the "Rumble in the Jungle," Foreman rebounded by defeating Joe Frazier two years later. Following a ten-year retirement, he made a successful comeback to recoup his lost fortune. Foreman became the oldest heavyweight champion at the time and amassed enormous wealth through his endorsement deal with Salton, Inc. His association with the George Foreman Grill has generated over $200 million.
