IBO world boxing rankings
The IBO rates a hundred fighters in every men’s division. The WBA, WBC, IBF and WBO each rate fifteen. That is the whole difference in a sentence, and it is why these tables are worth reading even if you regard the belt as a secondary one: below about tenth, the IBO is the only body publishing a considered opinion at all. It is also the only one that does not use a ratings committee, having handed the job to a computer in the late 1990s and to BoxRec, the independent record keeper, since 2014.
The women’s ratings go as deep as the field allows rather than to a fixed hundred, so most divisions carry about thirty names and the newest carry a handful. That is a fair reflection of how many professionals are actually active at each weight.
Every current IBO champion is listed below, followed by all 34 division tables. Movement is taken from the IBO’s own previous-month column rather than worked out by comparing two of our own snapshots, so a fighter who has moved is shown moving even in their first month on this site.
Current IBO world champions
17 of the 34 IBO world titles are currently held. A vacant title usually means the champion has moved division or been stripped for inactivity, and the IBO fills it from the top of the ratings rather than by invitation.

What the IBO is, and how seriously to take it
The IBO was founded in 1988 and is based in Coral Gables, Florida. It is not recognised by the WBA, WBC, IBF or WBO, who recognise only one another, and on that basis it is routinely described as a secondary belt. That description is fair as far as it goes and it is worth being straightforward about it rather than pretending otherwise.
What it misses is who has carried the belt. Lennox Lewis, Wladimir Klitschko, Manny Pacquiao, Floyd Mayweather Jr, Roy Jones Jr, Prince Naseem Hamed, Gennadiy Golovkin, Tyson Fury, Anthony Joshua, Oleksandr Usyk and Dmitrii Bivol have all held IBO titles, in most cases while holding one of the major belts at the same time. In several divisions the IBO strap has travelled with the undisputed championship rather than being contested separately, which is a different thing from a belt nobody wants.
The ratings are the stronger argument. Every other body runs a committee, and a committee can be lobbied. The IBO removed the committee, first with its own computerised system and since 2014 by using BoxRec’s independent ratings. The result is a table that sometimes disagrees sharply with the other four, and disagrees for reasons you can follow: activity, quality of opposition and time since the last contest, applied the same way to everyone. Whether an algorithm produces a better ranking than a committee is a fair argument. Whether it produces a more consistent one is not.
IBO rankings by division
Each division links to its full IBO table — a hundred names in the men’s divisions — with movement against last month, plus nationality, age, professional record and knockout count for every rated fighter.

Common questions about the IBO
- Is the IBO a legitimate world title?
- Yes, though it sits outside the group the sport treats as its top tier. The IBO is not recognised by the WBA, WBC, IBF or WBO, who recognise only each other. It has still been held by Lennox Lewis, Wladimir Klitschko, Manny Pacquiao, Floyd Mayweather Jr, Tyson Fury, Anthony Joshua, Oleksandr Usyk and Gennadiy Golovkin, and in several divisions IBO belts have been unified alongside the other four rather than defended separately.
- How are IBO rankings worked out?
- By computer rather than by committee. The IBO introduced a computerised ratings system in the late 1990s specifically to take subjective judgement out of the process, and since 2014 the ratings have been produced using BoxRec, the independent records keeper. Every other sanctioning body runs a ratings committee, which is why the IBO table in a division can look markedly different from the other four.
- How often are the IBO rankings updated?
- Monthly. The IBO publishes a new set of ratings at the start of each month and dates them to that month. These tables are the August 2026 ratings.
- How many fighters do the IBO rankings cover?
- One hundred in every mens division, where the WBA, WBC, IBF and WBO each rate fifteen. The womens ratings run as deep as the field allows rather than to a fixed number, so most carry about thirty names. Across 17 mens and 17 womens divisions the August 2026 sheet rates 2,172 fighters in total.
- What is the difference between the IBO and the IBF?
- They are separate organisations with similar initials. The IBF, the International Boxing Federation, is one of the four bodies the sport treats as major and rates fighters through a committee. The IBO, the International Boxing Organization, is a separate body based in Coral Gables, Florida, that rates fighters by computer and is not recognised by the IBF.
