Global MMA Championship Map: Seven Vacant Belts, Six Promotions and a Forgotten Weight-Class Error

On the evening of October 12, I sat in a cafe on Sukhumvit Road, Bangkok, rewatching Anatoly Malykhin's ONE Championship middleweight title defense. A Vietnamese friend messaged me: "Malykhin fights at middleweight, so why is he so big?" I replied that ONE's middleweight title is 205 pounds, not 185 like the UFC. Three minutes later, my friend wrote back: "So I've been getting it wrong this whole time?"

That was the moment I decided to sit down and cross-check the entire current MMA championship map across six major promotions: UFC, PFL, Bellator (absorbed into the PFL ecosystem), ONE Championship, Rizin, and Invicta FC. Not to list names, but to answer a question I considered more important: are Vietnamese fans reading this map correctly?

Context: six promotions, twenty-plus weight classes, one mess

After years of following mixed martial arts, I have always felt that the global championship map resembles a political map drawn with six different rulers. UFC calls itself the biggest fight promotion on the planet, ONE Championship positions itself as the Asia-Pacific power, PFL after absorbing Bellator has become the promotion with the most divisional belts among the second tier, Rizin holds Japan, and Invicta FC is the women-only stage.

What caught my attention was not who holds which title. It was the structure. Each promotion operates its own weight-class system, and that system differs not only in names but in actual numbers. UFC lightweight is 155 pounds. ONE lightweight is 170 pounds — equivalent to UFC welterweight. UFC welterweight is 170, ONE welterweight is 185, equivalent to UFC middleweight. UFC middleweight is 185, ONE middleweight is 205, equivalent to UFC light heavyweight. UFC light heavyweight is 205, ONE light heavyweight is 225.

This is a structural reality that has existed for years, not a typo, and it makes every cross-promotional title comparison physiologically distorted.

I once sat next to a Brazilian coach in Bangkok at a training seminar in the summer of 2026. He told me that when ONE fighters move to the UFC, they usually have to drop a full weight class. A ONE lightweight champion entering the UFC must fight at welterweight, because his body has been built for 170 pounds, not 155. Conversely, a UFC featherweight moving to ONE would fight at lightweight and could keep a size advantage.

This information matters more than its appearance suggests. It is why every debate about "can a ONE champion fight a UFC champion" starts from a false premise.

Core analysis: PFL is collecting belts, ONE is testing a two-belt model

The first thing the cross-reference reveals is PFL's belt structure. The promotion currently holds titles in six divisions: heavyweight with Vadim Nemkov, light heavyweight with Corey Anderson, middleweight with Costello van Steenis, welterweight with Thad Jean, lightweight with Usman Nurmagomedov, and women's featherweight with Cris Cyborg. Six divisions in a non-UFC promotion is a notable number.

Most of these champions came from the old Bellator or from the free-agency wave, which shows PFL is pursuing a strategy of accumulating second-tier stars rather than developing in-house.

Usman Nurmagomedov is the direct heir of the Dagestan training lineage, part of the same ecosystem as Islam Makhachev and Khabib Nurmagomedov. His holding the PFL lightweight title is not just a personal story; it is a sign that the Dagestan wrestling pipeline has become a cross-promotional fighter supply chain, no longer confined to the UFC. Cris Cyborg at PFL women's featherweight is another case — she has passed through UFC, Bellator, and now PFL, a journey reflecting how second-tier promotions try to anchor big stars with short-term contracts.

On the ONE Championship side, what stands out is not the number of belts but the two-belt model. Anatoly Malykhin holds both the light heavyweight and middleweight titles. Christian Lee holds both the lightweight and welterweight titles. This is deliberate policy, not an exception.

ONE's allowance for fighters to hold two belts simultaneously is a commercial instrument, because champion-versus-champion bouts are always the best-selling format in MMA.

If the UFC limits each fighter to one belt to protect divisional competitiveness, ONE chooses the opposite direction: creating more "champion versus champion" bouts each year, in exchange for some divisions getting stuck with champions who defend infrequently.

I spent many evenings in the fall of 2026 in Doha watching a Dutch scout explain this difference. He said that in Asia, a fighter holding two belts is not considered unprofessional; it is considered a sign of class. This view differs from how Western fans see it, usually demanding a champion defend continuously in a single division.

Meanwhile, Invicta FC shows an entirely different model. The promotion is women-only, and currently four of its five divisions have vacant titles: women's featherweight, women's flyweight, and women's strawweight are all vacant, leaving only women's bantamweight with Jennifer Maia holding the belt. Maia is a former UFC title challenger, and her landing in Invicta reflects a function rarely named: Invicta is a safety net for the women's martial arts labor force.

When the UFC cuts or releases female fighters, Invicta absorbs them, and this is precisely what keeps the lower-tier women's MMA labor market from collapsing.

On the UFC side, seven vacant belts across the system — men's heavyweight, women's featherweight, plus vacant titles in Rizin and Invicta — create a transitional picture. I do not have enough data to name the specific cause of each vacancy, but the pattern is clear: most vacant belts cluster in women's divisions and lighter divisions of smaller promotions.

Current UFC champions include Alexander Volkanovski at featherweight, Sean Strickland at middleweight, Petr Yan at bantamweight, Carlos Ulberg at light heavyweight, Joshua Van at flyweight, and Islam Makhachev at lightweight. The appearance of names like Joshua Van and Carlos Ulberg shows the UFC is in a generational transition in some divisions, as rising fighters begin to occupy positions once held by long-reigning former champions.

In ONE Championship, Xiong Jing Nan still holds the women's strawweight title — one of the longest reigns in Asian women's MMA. Her maintaining this position over many years is one of the most enduring stories I have followed, and it raises a question analysts rarely ask: what keeps a champion at the top for so long while an entire generation of fighters changes around them?

Contrarian angle: this map is not a power ranking

What I consider most important, and most easily misread, is how fans tend to read the championship map as a global power ranking. They assume a UFC champion is always stronger than a PFL champion, that a ONE champion is weaker than a UFC champion at the same nominal weight class.

This reading is wrong on two counts.

First, each promotion has a different weight-class system, so "the same nominal weight class" does not mean the same body mass. A ONE middleweight champion weighs 205 pounds, while a UFC middleweight champion weighs 185. Putting the two in the same cage without adjusting weight is a meaningless act athletically.

Second, opponent quality within a promotion cannot be measured by the promotion's name. A PFL champion may have fought in the UFC and lost there, but may also have beaten opponents a UFC champion has never faced. The championship map only shows who holds a belt where, not who is stronger in a hypothetical fight.

The championship map is a structural reference document about organizational configuration, not a competitive power ranking, and conflating the two is the most common fan error.

I once made this mistake. In 2026, during an evening at Souq Waqif in Doha, I heard an agent talk about an Ivorian winger about to move to the EFL Championship. At the time, I rushed to underestimate a club simply because it was not in the group most mentioned by media. Five days later, I understood that the accuracy of information does not depend on the fame of an organization, but on how I verified it. I carried that lesson into how I read the MMA championship map: never let a promotion's media ranking substitute for actual analysis.

There is another aspect this map exposes but few discuss. The existence of more than fifty men's championship belts across the system, plus dozens of women's belts, dilutes the title of "world champion." When every promotion awards its own world title for its own weight class, no one is truly a world champion in the absolute sense. This is a consequence of exclusive contracts — each fighter is locked into one promotion, and no promotion recognizes another's belts.

I remember standing in Moscow in the summer of 2026, hearing hundreds of journalists from around the world argue about who was the strongest team. Back then I understood that football has its own grammar. MMA does too, but that grammar is split into six dialects, and there is no shared dictionary.

What is actually changing

There are three signals I consider worth watching in the coming months.

The first is PFL's accumulation strategy. If PFL continues to hold six divisions with champions from the old Bellator, it will become the first second-tier promotion with enough depth to negotiate broadcast rights at a scale close to UFC. But if these champions leave one by one when contracts expire, the model collapses.

The second is ONE's two-belt policy. If the model keeps turning a profit, other promotions may follow. If it leads to divisions being frozen because champions are too busy defending in another division, other promotions will steer clear.

The third is the vacancy situation in women's divisions. Four of Invicta's five divisions are vacant, alongside the UFC women's featherweight title. This could be a sign of normal transition, or it could signal that the flow of lower-tier female fighters is slowing.

I have followed mixed martial arts events for over a decade, and what I have learned is that structural changes always precede ranking changes by about eighteen months.

When a division starts having frequent vacancies, it usually takes more than a year for a promotion to find a stable champion. When a promotion starts collecting belts from an absorbed organization, it usually takes two years for fans to get used to calling the new promotion by name. These are the time frames media usually ignores because they generate no headlines, but they determine who will be champion in three years.

People remember the champion's name; I remember how a division collapsed in silence when its belt was left vacant too long. A transfer is not a transaction — it is a conversation about the fear of being forgotten — and in today's MMA world, at least seven divisions are having that conversation at once.

The truth this championship map exposes is not who holds a belt. It is how many belts sit vacant, and each vacancy is an unanswered question about how that promotion will find a successor. Seven vacant belts across six promotions are seven open questions. And their answers will shape next year's championship map, not the titles currently draped over today's champions.

That night in Bangkok, I turned off the screen and thought about my Vietnamese friend's question. He did not ask wrong. He asked a question many fans have never been given the tools to answer. That is why I write. That is why I still sit down after every fight, checking every number, every weight class, every fighter's name — so that at least one reader will no longer misread this sport's map.
