Bob Arum, 87 – Price Undisclosed
Robert “Bob” Arum is a boxing promoter, lawyer, and businessman. He is famous for being the head honcho of Las Vegas-based boxing promotion company, Top Rank. Having previously worked for the US Attorney’s Office, it was when he decided to become a boxing promoter that he started to become famous (or infamous)—mostly for numerous controversies and feuds he was involved in. Arum was involved in a feud that lasted for 40 years with co-promoter Don King. With a net worth of $300M, it’s just fitting for Arum to have a luxurious mansion in Las Vegas, Nevada which is known as a popular boxing bout venue.
