12. Eddie Hearn
As one of boxing’s most visible promoters, Hearn is incredibly successful. He is one of the faces of British boxing and represents the likes of Anthony Joshua and Tony Bellew. Furthermore, he worked with Canelo Alvarez in 2021. Barry Hearn founded the Matchroom promotion and passed it down to his son. However, it’s impossible to work in the world of boxing without being involved along some of the sports’ shadiest figures.
While Hearn avoids personal controversy, he isn’t afraid of working with those standing knee-deep in it. He has relationships with cartel boss Daniel Kinahan and MTK. Meanwhile, he has led boxing to Saudi Arabia where Crown Prince Muhammad Bin Salman throws money at the sport. This is because Bin Salman wants to sports-wash his country so people ignore their horrendous human rights record.
