Sixty years ago, a 34-year-old Harvard Law School graduate with no boxing promotion experience staged a heavyweight title defense at Maple Leaf Gardens in Toronto. Muhammad Ali became the champion. The challenger was George Chuvalo. The promoter, Bob Arum, was a former federal prosecutor who stumbled into the fighting industry almost by accident.

On March 29, 1966, Arum’s boxing career began. It hasn’t stopped since then.

Ali defended his title that night via unanimous decision over the rugged Canadian, but it was the circumstances surrounding the fight that put Arum to the test. Cities across the United States refused to accommodate Ali due to his vocal opposition to the Vietnam War, and Arum stepped forward to keep the fight north of the border. By all accounts, it was a challenging first promotion.

“60 years is a long time. I have met fantastic people and it has been a great adventure,” Arum said in a statement released by the company. “People ask what my hardest promotion was. The hardest promotion was my first fight, I’m just starting to fight. Everything else was uncomplicated in comparison.”

From the Department of Justice to the Ring

Arum’s path to boxing was unconventional. A native of Brooklyn, he graduated from Harvard Law School and began working as a federal prosecutor under U.S. Attorney General Robert F. Kennedy. In 1962, as head of the tax department of the Southern District of Recent York, he oversaw the seizure of proceeds from the Floyd Patterson vs. Sonny Liston heavyweight championship fight. A few years later, while in private practice, he met Ali, and the bond that developed changed the sport.

What started with one fight in Toronto turned into 27 Ali fights promoted or co-promoted by Arum and Top Rank. From there, the company became a major force in the Four Kings era of the 1980s, producing major fights featuring Sugar Ray Leonard, Marvin Hagler, Thomas Hearns and Roberto Duran. Arum later guided George Foreman to an improbable return to the heavyweight title at the age of 45 and guided Manny Pacquiao through championship campaigns in eight weight classes.

The list of fighters who turned professional, developed and won championships under the Top Rank banner reads like the history of the sport itself: Oscar De La Hoya, Floyd Mayweather Jr., Miguel Cotto, Michael Carbajal, Donald Curry, Teofimo Lopez, Shakur Stevenson, Jose Ramirez, Oscar Valdez, Vasiliy Lomachenko, Terence Crawford and Naoya Inoue, among dozens of others.

Numbers in six decades

Hall of Fame matchmaker Bruce Trampler, who has been with the company since 1980, compiled a statistical summary that sheds airy on the scope of Top Rank’s activities. The company promoted 2,203 boxing cards, including 722 world title fights, in 223 U.S. cities and 95 foreign cities in 30 countries. Top Rank promoted shows in 43 of 50 states. It aired 940 shows on ESPN, 129 on HBO, 98 on CBS and 73 on ABC.

Seventy-five Hall of Fame players competed under the Top Rank banner. Seven company personnel have been inducted into the International Boxing Hall of Fame: Arum, Teddy Brenner, Irving Rudd, Bruce Trampler, Lee Samuels, Brad Jacobs and Brad Goodman.

Total number of individual fighters: 41 fights for Miguel Cotto, 37 fights for Oscar De La Hoya, 35 fights for Floyd Mayweather Jr., 26 fights for Manny Pacquiao, 24 fights for Terence Crawford and 20 fights for Marvin Hagler. Even a teenage fighter like Xander Zayas, who is only 22 years vintage, already has 19 fights under his belt promoted by Top Rank. Abdullah Mason also has 19.

And at the bottom of Trampler’s book is a footnote: one jump in Snake River Canyon promoted by Bob Arum for Evel Knievel.

Adaptation in different eras

The boxing business that Arum started in 1966 is almost nothing like what it is today. When he promoted the Ali vs. Chuvalo fight, there were no satellites capable of broadcasting the fights internationally. The CCTV model that generated revenue from major events was still in its early stages of development. Pay-per-view didn’t exist. Streaming has been a thing for decades.

“The last thing I imagined at that point was being a boxing promoter,” Arum said. “When I started, there were no satellites to broadcast fights to another country. This technology didn’t exist. Since then, everything in boxing has changed, from what I did in the beginning to what I do now, 60 years later. The biggest lesson I learned was that you have to be malleable enough to know that it won’t always be the same.”

This flexibility has been tested more recently than ever before in the company’s history. When Top Rank’s long-term cooperation with ESPN ended in mid-2025, the company was left without a television station for the first time in decades. Arum filled that gap by placing fighters on other promoters’ cards, launching a free FAST channel on Tubi, Pluto TV and Roku, and ultimately signing a multi-year media rights deal with DAZN that brought the company’s entire roster and six-decade archive to a platform that now hosts most of professional boxing’s top promotions.

Current lineup and future

At age 94, Arum continues to develop the next generation of players. Keyshawn Davis, Xander Zayas, Abdullah Mason and Bruce Carrington represent the latest wave of top-ranked prospects building toward world title contention. The model is the same one Arum has used for decades: sign talented teenage players, develop them on regular cards, and position them for a shot at a championship when they’re ready.

This model currently exists in a boxing environment that is more competitive and structurally elaborate than anything Arum has navigated before. Zuffa Boxing, backed by TKO Group Holdings and Saudi investment, entered the sport with the financial scale and corporate infrastructure of a publicly traded conglomerate. The amendments to the Ali Act currently being considered by Congress could change the regulatory framework under which all promoters operate. Arum himself was one of the bill’s most vocal opponents, warning Congress that the three basic fighter protections established in Ali’s original bill would be taken away from any boxer who signed a contract with the United Boxing Organization.

The competitive dynamics are different. The economics are different. The platforms are different. However, the core business of identifying talent and building champions remains unchanged, and no dynamic promoter has done it longer or at a higher level than Arum.

“When I look back, what I’m most proud of in my 60 years in this sport is that I stuck with it as long as I could, both physically and mentally,” Arum said. “It’s not uncomplicated being a promoter.”

Top Rank will commemorate this anniversary throughout 2026 with archived programming, special features and original digital content spanning the company’s past, present and future.
