There are four main boxing belts: the WBA, WBC, IBF and WBO. In football there is one world champion, in tennis there is a world No 1, but in professional boxing each weight class can have four world champions at once, one from each organisation. Each runs its own rankings, names its own challengers and hands out its own belt. A boxer who has collected all four is called the undisputed champion. Reaching that summit is hard; staying there is even harder.
How many belts are there in boxing?
The championship belts recognised by the whole industry are issued by four organisations. Here are the boxing belts in order of appearance:
- WBA (World Boxing Association) — under this name since 1962, with roots going back to 1921;
- WBC (World Boxing Council) — founded in 1963;
- IBF (International Boxing Federation) — the international division appeared in 1983;
- WBO (World Boxing Organization) — founded in 1988.
The Ring magazine belt stands apart: it does not belong to any federation. And the WBA can have several titles of different levels in a single weight class. So the honest answer to how many belts there are in boxing is this: four main ones, but the number of boxing belts holders in one weight class can be higher.
WBA, WBC, IBF, WBO meaning: where the four boxing organisations came from
WBA — the oldest
The World Boxing Association grew out of the National Boxing Association of the United States, founded in 1921. On 23 August 1962 it was renamed the World Boxing Association — that was how the American body declared itself international.
WBC — a Mexican initiative
The World Boxing Council was founded on 14 February 1963 on the initiative of Mexican President Adolfo López Mateos. Eleven countries were founders, among them the United States, England, France, Mexico, the Philippines and Brazil. From 1975, José Sulaimán led the council for more than 38 years; since 2014 the president has been Mauricio Sulaimán. The WBC itself claims 166 member countries.
IBF — from an American association to an international one
The International Boxing Federation began with the United States Boxing Association (USBA), which held its first congress in 1977. In April 1983 its members voted for the international division USBA-I headed by Robert W. Lee Sr, its first president. In 1984 the organisation became known as the IBF/USBA, and since 2018 it has operated simply as the IBF. Its headquarters are in New Jersey.
WBO — the youngest of the four
The World Boxing Organization appeared in 1988 in San Juan, Puerto Rico: a group of Puerto Rican and Dominican businessmen walked out of the WBA congress over a dispute about the rules. The new organisation’s first title fight was won by Thomas Hearns — he took the vacant super-middleweight belt. Recognition did not come immediately: the WBC only began counting WBO champions in its rankings in 2004, and the IBF by 2007.
Boxing belts ranked: which belt is the most prestigious?
There is no official hierarchy. All four titles are equal: a WBO champion is as much a world champion as a WBC belt-holder. The difference lies in history. The WBA and WBC are two decades older than the rest, while the WBO belt was the last to be recognised by the other organisations, only in the 2000s. Many fans rate The Ring belt above all, because it cannot be won by a committee decision, only by beating the best. But the main value in any weight class is the same — all four boxing belts in one pair of hands.
Undisputed champion boxing meaning and The Ring belt
The definition is simple: the undisputed boxing champion holds the WBA, WBC, IBF and WBO titles at the same time. Give up or lose one belt and the status disappears, even if the boxer has never lost to anyone. When there were three organisations, the holder of three belts was called undisputed. Since 2007, when the WBO was finally recognised by the other organisations, all four belts are needed for that status.
The belt of The Ring magazine, founded by Nat Fleischer in 1922, was conceived as a mark of the ‘linear’ champion — the man who beat the previous best. In November 2024 the magazine was bought by Turki Alalshikh, head of Saudi Arabia’s General Entertainment Authority, under whose auspices the biggest boxing nights of recent years have been staged. Critics see a conflict of interest: the same people now stage fights and influence the magazine’s rankings.
WBA Super Championship: why the association has several champions
The most confusing system belongs to the oldest organisation. In 2000 the WBA introduced the title of super champion: it was given to boxers who simultaneously held a belt from another organisation, or to those who had defended the WBA title five or more times. As soon as a super champion appeared, the ‘regular’ title was declared vacant and contested again. Add interim champions in case the main one cannot make a defence in time, plus the ‘gold’ title introduced in 2019, and the WBA could have several belt-holders in a single weight class at once.
In August 2021 the Association of Boxing Commissions (ABC) wrote to the WBA that such a number of titles misled both the public and the boxers themselves, and threatened to recommend that American commissions not recognise WBA belts. The organisation declared all interim titles vacant and promised to reduce each weight class to one champion. The plan was never fully carried through, and since 2024 the WBA has again sanctioned interim bouts.
Mandatory defences: why belts scatter
Each organisation has its own No 1 ranked fighter — the mandatory challenger. The IBF’s championship bout regulations illustrate the mechanics well:
- a champion must defend the title against the highest available challenger within nine months of winning it, and thereafter at intervals of no more than nine months;
- if the parties fail to agree terms within 30 days, the right to stage the fight is decided at a purse bid;
- between mandatory defences, voluntary ones may be held — against a boxer from the IBF’s top fifteen.
Four organisations mean four queues of challengers, and they rarely match what the public wants. Hence the paradox: undisputed champions most often lose their status not in the ring but in the offices.
Why did Usyk vacate his belts?
The best example is Oleksandr Usyk. In May 2024 he became undisputed heavyweight champion, and barely a month later he gave up the IBF belt: his contract with Tyson Fury contained a rematch clause, and the federation had its own mandatory challenger. The interim title was won by Daniel Dubois, who was then elevated to full champion.
In November 2025 the story repeated itself: Usyk refused to make a mandatory defence against Fabio Wardley and vacated the WBO belt, and the Briton who had won the interim title was declared full champion. On 23 May 2026, at the pyramids in Giza, Usyk stopped former kickboxing world champion Rico Verhoeven in the 11th round and retained the WBA, WBC and The Ring belts. Then on 26 June he announced he was leaving the WBA, WBC and IBF belts so that the next in line could fight for them. He did not retire from boxing, however, and promised one more, final fight. The Ring belt stayed with him.
Boxing world champions list: who has collected all the belts
Oleksandr Usyk
The Ukrainian won his first undisputed title at cruiserweight: in July 2018 he beat Murat Gassiev. At heavyweight he did it twice. On 18 May 2024 in Riyadh he beat Tyson Fury by split decision (115-112 and 114-113 for two judges, 113-114 for the third) and became the first undisputed heavyweight boxing champion in 24 years. On 19 July 2025 at a 90,000-strong Wembley he knocked out Dubois in the fifth round and collected all the belts again. We looked at how a split decision differs from a majority decision in our piece on how fights are scored in MMA: boxing judges also score rounds on the 10-point system.
Terence Crawford
The American became undisputed champion in three weight classes: at light-welterweight (2017), welterweight (2023, beating Errol Spence) and super-middleweight. He took the last title on 13 September 2025 in Las Vegas from Saúl ‘Canelo’ Álvarez — by unanimous decision, 116-112, 115-113, 115-113. The Mexican had previously collected all the belts in that weight class twice: in 2021 and in May 2025. On 16 December 2025 Crawford announced his retirement with a record of 42-0.
Naoya Inoue
The Japanese fighter collected all the belts at bantamweight in December 2022, then moved up to super-bantamweight and on 26 December 2023 knocked out Marlon Tapales in the tenth round. That made him the second man after Crawford to be undisputed champion in two weight classes in the four-belt era. On 2 May 2026, at a packed Tokyo Dome (55,000 spectators), he beat the unbeaten Junto Nakatani by unanimous decision — 116-112, 116-112, 115-113 — and retained all four titles with a record of 33-0.
Beterbiev and Bivol: undisputed boxing champions from Russia
At light-heavyweight all four belts changed hands twice in four months between two Russians. On 12 October 2024 in Riyadh, Artur Beterbiev beat Dmitry Bivol by majority decision and became undisputed champion. On 22 February 2025 in the same city Bivol took revenge, also by majority decision (116-112, 115-113, 114-114), and took all the belts for himself. In April 2025 he vacated the WBC title, choosing a third fight with Beterbiev instead of a meeting with interim champion David Benavidez, and lost undisputed status.
Who is the undisputed boxing champion now?
As of October 2026 there is only one undisputed men’s champion — Naoya Inoue at super-bantamweight. He has held all four belts since December 2023, and the Japanese fighter’s next bout is scheduled for early 2027.
At heavyweight, after Usyk’s departure, the four belts are once again held by four different men:
- WBA — Murat Gassiev: in the summer of 2026 he was elevated from ‘regular’ to full champion, and on 11 July in Moscow he made his first defence, stopping Peter Kadiru in the sixth round;
- WBC — Agit Kabayel: after Usyk vacated, he was elevated from interim champion to full champion;
- IBF — Filip Hrgović: on 29 August 2026 in London he won the vacant belt, stopping Moses Itauma in the ninth round, and became Croatia’s first heavyweight world champion;
- WBO — Daniel Dubois: on 9 May 2026 in Manchester he survived two knockdowns and stopped Wardley in the 11th round, and on 17 October in the rematch in London he ended the fight in the second.
The Ring belt at heavyweight still belongs to Usyk. At light-heavyweight Bivol holds three of the four belts — WBA, IBF and WBO — while the WBC title in that weight class is vacant.
How to read titles in fight announcements
When a boxer is called a ‘world champion’, it is worth checking: which organisation’s belt it is, whether it is full or interim and, if it is the WBA, whether it is super or ‘regular’. There can only be one undisputed champion in a weight class, so every such title becomes an event.
Frequently asked questions about boxing belts
How many belts are there in boxing?
There are four main championship belts — WBA, WBC, IBF and WBO. The Ring magazine belt exists separately, and the WBA can have a super champion, a ‘regular’ champion and an interim champion in a single weight class.
Which boxing belt is the most prestigious?
There is no official hierarchy; all four titles are equal. The oldest organisations are the WBA and WBC, but the status of undisputed champion — all four belts at once — is valued above any single belt.
What does undisputed boxing champion mean?
It is a boxer who simultaneously holds the WBA, WBC, IBF and WBO belts in his weight class. If he gives up or loses even one belt, the status disappears.
Who is the heavyweight boxing champion now?
As of October 2026 there is no undisputed heavyweight champion: the WBA belt is held by Murat Gassiev, the WBC by Agit Kabayel, the IBF by Filip Hrgović and the WBO by Daniel Dubois. The Ring belt remains with Oleksandr Usyk.
Why did Usyk give up his belts?
He vacated the IBF belt in 2024 and the WBO in 2025 to avoid mandatory defences. On 26 June 2026 Usyk left the WBA, WBC and IBF belts, explaining that he wanted to give the next challengers a chance, and promised one more fight.
Which Russians have become undisputed world champions?
In the four-belt era — Artur Beterbiev (October 2024) and Dmitry Bivol (February 2025), both at light-heavyweight.
