8. Wladimir Klitschko – Net Worth: $90 Million
Boxing’s former heavyweight world champion Wladimir Klitschko and his brother Vitali were dominant partners for more than a decade.
Klitschko was in the ring known as one of the best and most technical boxer of his generation, but perhaps best known for disciplined work, as he accrued his fortune through lucrative purses and with backing from sponsors such as Mercedes Benz and SAP making him one of the richest boxers in the world.

Klitschko’s wealth testifies to his refined tastes. He has a Mercedes-Benz G Class and owns a number of luxury cars and likes jetting around Europe. Real estate is one of his biggest investments, and he owns properties in Germany and the U.S. As a philanthropist even though he’s rich, Klitschko supports a number of educational causes.
