[2][3] He has held the undisputed championship[a] in the light-heavyweight division since 2024, as well as the Ring magazine and International Boxing Organization (IBO) titles.

[8] At the 2008 Olympics he beat Kennedy Katende 15:3, then at the round of 16 he fell controversially to local boxer Zhang Xiaoping who went on to win the gold medal.

At the 2009 World Championships, he beat young Cuban Jose Larduet and Uzbek Elshod Rasulov to claim the light heavyweight title.

Beterbiev fought on the undercard of Jean Pascal vs. Lucian Bute, beating Gabriel Lecrosnier by TKO on the fourth round.

[14] After winning his first five professional bouts, Beterbiev would face off against former IBF light-heavyweight champion Tavoris Cloud for the vacant NABA title on 27 September 2014.

[15] In December 2014, Beterbiev stopped light heavyweight prospect Jeff Page Jr. in two rounds, winning the vacant IBF North American and NABO light-heavyweight titles.

Finally in the fourth, Beterbiev would land a straight/uppercut hybrid that would hit Campillo square on the chin, and followed it up with a perfunctory left hook before walking to his corner while his opponent slid to the canvas, barely conscious.

He was scheduled to face Enrico Kölling, with the winner becoming the IBF's mandatory challenger to unified world champion Andre Ward, but the fight was never finalized amidst Beterbiev's contract dispute.

[25] A purse bid was later won by Top Rank, with the American promotion planning to broadcast the fight on ESPN, as part of a show including Jessie Magdaleno.

[31] In October 2018, Beterbiev fought British champion Callum Johnson in a mandatory defence of his IBF world title in Chicago.

[32] Johnson, ranked 7th in the world with the IBF at the time, was coming off a round 1 TKO of domestic rival Frank Buglioni; his first fight in nearly one-and-a-half years.

[33] Beterbiev accepted the fight on a co-promotional deal with Matchroom Boxing USA, which was aired live on DAZN in the US and on Sky Sports in the UK.

[39][40] On 20 March 2021, Beterbiev stopped Deines in the tenth round with a vicious left hook, handing him his first KO defeat in his professional career.

[44] Beterbiev's second unified title defense was booked for 17 December 2021, and took place at the Bell Centre in Montreal, Quebec, Canada.

[45] Beterbiev began to take over the bout from the fourth round onward, during which he suffered a bad cut from an accidental clash of heads, and won the fight by a ninth-round technical knockout.

[46] On 13 February 2022, Top Rank boss Bob Arum revealed that Beterbiev was in ongoing negotiations with WBO light-heavyweight champion Joe Smith Jr.

The planned three-belt light-heavyweight unification bout would take place in summer, as Beterbiev would be unable to face Smith Jr. earlier due to his participation in Ramadan.

[48] In a dominant performance, Beterbiev knocked down Smith Jr. three times in the opening two rounds en route to a second-round technical knockout, unifying three major world light-heavyweight titles.

"[49] Beterbiev was expected to make a mandatory title defense against the number one ranked WBO light heavyweight contender Anthony Yarde on 29 October 2022 at The O2 Arena in London, England.

He knocked Yarde down with a counter right hook to an attempted uppercut, which floored the British fighter at the midway point of the round.

[55] On 15 March 2023, Beterbiev was ordered by the WBC to make a mandatory title defense against the former WBA super middleweight champion Callum Smith.

[62] Beterbiev was expected to face the WBA light heavyweight champion Dmitry Bivol for the undisputed title on 1 June 2024.

A judge ruled that a promised purse, which Beterbiev stated was not completely paid by the following March, over a December 2015 bout with Isidro Prieto, and the fact that Beterbiev agreed to a process of elimination bouts to secure the International Boxing Federation World Light Heavyweight title, despite a four-bout-a-year contractual agreement, did not cause any prejudice to his career.

"We are proud of the work we have done with Artur during our association, and we wish him the best success in the pursuit of his career", said promoter Yvon Michel after the settlement agreement.
