Conor McGregor: $35 Million
Although not a traditional boxer, Conor McGregor's net worth is expected to soar even higher than his current $35 million following his 2017 fight with Floyd Mayweather Jr. McGregor began his athletic career with boxing training in his youth but later transitioned to mixed martial arts (MMA). His relentless taunting of Mayweather eventually led to the historic fight, which guaranteed McGregor a minimum of $100 million, with the potential to reach $150 million.
