Six Promotions, More Than Twenty Divisions: The Map of Global MMA Championship Belts and the Quiet Gaps Behind It

Late Night in Nha Trang, One Notebook, and Six Names

Late at night in Nha Trang, when the waves on the beach had receded into the distance and the day's heat was only an echo, I sat alone at an old wooden desk with a ruled notebook and a two-color pen. On the left side of the page I wrote the names of organizations; on the right, the weight classes. In the middle, a space to mark who holds the belt. I had done this for decades, but tonight was different. For the first time in my career, I had to rule six columns, because MMA championship belts no longer fit on a single promotion's shelf. UFC, PFL, ONE Championship, Rizin, Invicta FC, and the shadow that dissolved but never vanished — Bellator. Six names, six systems, six ways of defining what a "champion" is.

Every season has its own heartbeat; you only need to listen carefully. But this time the heartbeat came not from one season of one sport, but from an entire ecosystem. I am not writing about a single fight. I am not writing about a knockout or a choke that made people hold their breath. I am writing about a map — a map showing where power in the world's mixed martial arts lies, where it is flowing, and what gaps it is leaving behind. People usually look only at the throne. As for me, after years of following fighters from training rooms to locker rooms and across time zones, I have learned that the gaps are where the truth speaks loudest.

Tonight my notebook has twelve ruled lines for each organization. Some lines have names; some remain empty. Those empty lines keep me awake. Because in MMA, an empty belt is never just a belt. It is an injured fighter. A failed negotiation. A forgotten division. It is the imbalance between regions and television markets. I sat for a long time in front of that page, and I understood that I needed to write it out, slowly and carefully, as I promised myself after every stumble.

Friends and colleagues say I "write gently." I never break a hot story. I let others chase headlines, let others be first, while I verify. But there is one thing I have realized after all these years: gentle does not mean evasive. Gentle means that when I write, I write solidly, so readers can trust it, and so that no one is wounded by my pen. Tonight, with a map that has no direct protagonist, no one to defend or attack, I will try to retell the story that the map tells me.

Context: One World Divided Into Six Homes

Before going into detail, we need to picture the setting clearly. Mixed martial arts — the name that Vietnamese people still call "võ tổng hợp" — has gone through more than three decades of formation and transformation. From a controversial startup event in 2026, it has become a global entertainment industry with billions of dollars in revenue, hundreds of millions of fans, and a web of championship belts as tangled as a spider's net.

The current structure can be pictured in four tiers. At the top is UFC — by the international media's own phrasing, the largest MMA organization in the world. UFC holds the tightest exclusive contract system, the most popular pay-per-view television system, and the highest-rated roster of fighters. Just look at how fighters speak when they want to leave, and you will understand UFC's central position — nearly every career path has one mandatory point of passage through that house, whether to enter or to exit.

One tier down, ONE Championship is a special force. This is the strongest MMA organization in Asia — Thailand and Singapore are key bases, along with a series of events in Southeast Asia, and especially the Philippines, a country where mixed martial arts is nearly a national sport alongside basketball. ONE has a different weight-class system, a policy allowing one fighter to hold multiple belts simultaneously, and an event-presentation style that blends boxing, Muay Thai, kickboxing, and MMA. For Asian audiences, ONE is far closer than UFC.

The third tier is PFL — Professional Fighters League. The most notable thing about PFL in the current picture is not PFL itself, but the fact that it has absorbed almost the entire Bellator legacy. Bellator was once America's second-largest organization for many years, but then its business stalled, and at the time of this analysis, although Bellator remains named in the list of organizations, it no longer contributes any champions. In other words, Bellator has become a shadow. PFL now carries an army of many former Bellator champions plus some former UFC fighters — a heterogeneous mix with both advantages and risks.

The fourth tier is regional and specialized organizations. Rizin holds an important role in Japan, inheriting the legacy of Pride FC — the legendary organization whose name any Japanese MMA fan mentions with regret. Invicta FC is even more special: it is an all-women organization, acting as a "transfer station" for female fighters, where some rebuild careers after leaving UFC while others start from zero.

These six homes coexist in one ecosystem, but the rules are not entirely the same. UFC, PFL, and Invicta compete under the Unified Rules of MMA. ONE Championship has its own modified ruleset, particularly in scoring and in weight boundaries. Rizin operates by Japanese MMA tradition. This difference, as I will discuss in detail later, is not small. It is one of the biggest blind spots for casual fans.

I remember clearly a trip to Bangkok a few years ago, sitting in a hotel corridor after a ONE event, talking with a Filipino coach. He told me something I wrote down immediately: "People think that if they're both called middleweight, they're the same, but here, our middleweight is twenty pounds heavier than the American middleweight." At the time I only nodded. It was not until tonight, when I ruled that six-column table, that I fully absorbed his words.

Core: Going Through Each Organization, Each Division

Now I will enter the main section, the one that consumes most of my ink. I will go through each arena, each division, retelling who holds the belt, and where the points of attention are. I will not make predictions about specific fights, because this map does not give me enough data to do so — and if anyone asked me to predict an unscheduled fight, I would rather stay silent.

UFC — The House at the Summit

UFC is where everything begins and where everything is priced. In the overall picture, UFC holds nearly all the important men's divisions and most of the women's divisions. Yet there is one notable feature: UFC is the organization with a significant number of vacant belts in the current picture.

The UFC heavyweight division is currently vacant. This is something few would expect from an organization always seen as the center of MMA. The men's heavyweight division is considered the most prestigious, where the heaviest and strongest fighters compete. A vacant belt here is never normal. It usually reflects one of three situations: the champion just retired, the champion suffered a long-term injury, or UFC is considering a bigger fight and deliberately keeping the division waiting.

The UFC women's flyweight division is also vacant. This is a sign that UFC's women's divisions are going through a realignment phase. UFC's women's divisions were born later than the men's, have fewer fighters, and therefore every vacant belt has far greater impact than the same event in a men's division.

Speaking of UFC, we cannot fail to mention names who came to MMA from other foundations. Sean Strickland is an example — a controversial man who has never been bland. Alexander Volkanovski is a champion from Australia who built his career on a kickboxing base then gradually rounded out his wrestling. Carlos Ulberg also comes from Australia, a name showing the strong development of MMA in Oceania. Joshua Van represents a new trend — young fighters from territories the international media often overlooks but who are trained very systematically.

What catches my attention most about UFC is not who holds the belts but the speed of turnover. During the period I have followed, the number of new UFC champions in a single year can reach a figure that only a few years ago would have been thought impossible. What does this mean? It means the successor generation at UFC has thickened very quickly. On one hand this is good news for the sport — the next generation is ready to inherit the throne. On the other, it raises a question about stability. When the throne changes hands constantly, the value of the belt becomes hard to measure.

PFL — An Army Recruited, Not Cultivated

PFL is the most noteworthy case in the whole picture. Looking at their champion list, I have a hard-to-describe feeling — as if reading a war roster recruited from many sources rather than the product of a single academy.

The PFL heavyweight title is held by Vadim Nemkov — a name tied to Russia and the formidable wrestling lineage of that region. The light heavyweight is held by Corey Anderson, a former UFC fighter who came to PFL as a new chapter. Middleweight is Costello van Steenis; welterweight is Thad Jean — a name evoking young fighters from the Caribbean, where MMA is still finding its development path. The lightweight title belongs to Usman Nurmagomedov, a name that anyone following MMA knows is tied to the Dagestan wrestling empire — which has produced an entire generation of fighters with extremely solid grappling foundations.

The most important point about PFL is this: most of their champions are former Bellator champions or former UFC fighters. In other words, PFL owns a recruited army, not one cultivated from scratch. This is a business strategy, and it has its own logic. Instead of spending decades training fighters and building a brand from zero, PFL chooses to buy already-established talent. But this strategy also raises a central question that perhaps only time can answer: is a PFL champion equivalent in caliber to a UFC champion?

I do not answer that question. I only observe. And what I observe is this: in PFL's roster building, there is a clear power shift. Bellator was once the home of fighters who could not find a place in UFC. Now Bellator is gone, and that role has shifted to PFL. The difference is that PFL has greater financial resources and more promotional ambition than late-period Bellator. Is that enough to create a widely recognized champion class? This is the question every analyst is awaiting.

On the PFL list there is one more notable name: Cris Cyborg, women's featherweight champion. Cyborg is one of the greatest female fighters in the sport's history, someone who transformed an astonishing physical frame into an extremely dangerous tactical weapon. The fact that PFL has Cyborg on its roster says a great deal about its ambition in women's divisions — and also about the scarcity of elite female talent on the market.

ONE Championship — A Weight System So Different It Is Confusing

ONE Championship is the section where I spent the most time taking notes, because this is precisely where the most serious public misunderstandings arise. I will begin with concrete facts, then draw conclusions.

ONE Championship operates a different weight-class system than UFC. Specifically, ONE's light heavyweight limit is 225 lbs, while UFC and PFL define light heavyweight at 205 lbs. ONE's middleweight limit is 205 lbs, while UFC middleweight is 185 lbs. ONE's welterweight is 185 lbs versus UFC's 170 lbs. ONE's lightweight is 170 lbs versus UFC's 155 lbs. ONE's featherweight is 155 lbs versus UFC's 145 lbs. ONE's bantamweight is 145 lbs versus UFC's 135 lbs. ONE's flyweight is 135 lbs versus UFC's 125 lbs. ONE's strawweight is 125 lbs, and ONE's women's strawweight is also 125 lbs. ONE's atomweight is 115 lbs.

Simply put: ONE's weight classes are pushed about one tier higher than UFC's — roughly twenty pounds. A ONE "middleweight" weighs the same as a UFC "light heavyweight." A ONE "welterweight" weighs the same as a UFC "middleweight." This is not a data error, nor a naming confusion. It is a structural feature of ONE that has existed for many years.

What does this mean? It means that when a casual fan reads "ONE's middleweight champion successfully defended his belt," they may accidentally equate the value of that belt with a UFC middleweight championship. That is a category error. Two belts with the same name but different weights. Two champions with the same title but different weight classes. This is one of the biggest blind spots in how the media covers MMA.

Why did ONE choose such a different system? There are several hypotheses. Some say it is to fit the body frames of Asian fighters — Thailand, the Philippines, Indonesia, Myanmar, Japan, Korea — countries whose average skeletal frames may differ from Western fighters. Others say it is a commercial choice, creating a distinct weight-class system so ONE is not compared one-to-one with UFC. Whatever the reason, the result is clear: ONE's weight system pushes the boundaries higher, and that affects everything from fighters' weight cuts to how people compare champions across promotions.

As for figures, ONE has notable names. Anatoly Malykhin is a special case, holding two belts at once — light heavyweight and middleweight. Christian Lee also holds two belts at once — welterweight and lightweight. This is something ONE permits and even encourages, because "champion versus champion" fights are the most commercially attractive format in any combat sport. A fight between two champions holding belts in two divisions always sells more tickets, draws more viewers, and creates more debate than any other.

In women's divisions, ONE has Xiong Jing Nan — a women's strawweight champion who has been with the organization for years. Her presence speaks to ONE's serious investment in women's divisions, something not every organization can do at that scale. Alongside her are names like Enkh-Orgil Baatarkhuu — representing Mongolian MMA, a region emerging as a new talent source for the region's martial arts.

I once watched a ONE event in Bangkok, sitting among thousands of cheering Asian fans. The atmosphere was completely different from a UFC event in Las Vegas. The fans were closer, more passionate in their own way, and Asian fighters received support they might not have at a Western arena. That is why I often tell young colleagues: do not take UFC as the only measure for everything. This world is broader than people think.

Rizin — The Keeper of the Japanese Flame

Rizin Fighting Federation is a respected name in Japan. It inherits the spirit of Pride FC — the legendary promotion that once lifted Japanese MMA to the world summit in the 2000s before disbanding. Rizin maintains a special presentation atmosphere: a large stage, grand sound, and a respect for Japanese martial traditions hard to find in Western promotions.

In the current picture, Rizin holds several divisions. The light heavyweight is vacant — a sign that this division may be struggling for personnel. The lightweight is held by a champion whose name suggests a Central Asian or Caucasus technical base. The featherweight has champions Shaydullaev and Wakamatsu — two names evoking the blend of Eastern and Western technique that is characteristic of modern Japanese MMA. The bantamweight belongs to a champion named Sabatello. The super atomweight belongs to Izawa.

Looking at this list, the most visible thing is that Rizin maintains a fairly complete division system but the personnel below lightweight is somewhat thin. This reflects the reality of a regional organization: they do not have an endless supply of top fighters like UFC, and they must compete with both ONE and other Japanese organizations to retain talent. Yet precisely because of this, Rizin has a special role: it is where many Japanese fighters build their names before stepping onto the world stage.

I remember a remark by a Japanese coach I once interviewed on a business trip. He told me that Japanese MMA is not just about winning and losing, but about preserving a path. That path may be narrower than UFC's, but it is deep. And I think Rizin is the emblem of that depth — an empty arena, yet I hear the applause of those who do not give up.

Invicta FC — The Safety Net of Women's MMA

Invicta FC is the most special case among the six organizations, because it is the only all-women organization. Its role in the ecosystem is fairly clear: it is where young female fighters begin their careers, and also where some female fighters who once competed in UFC return after their careers no longer go the desired direction.

In the current picture, Invicta has several belt issues. Women's featherweight is vacant. Women's flyweight is vacant. Women's strawweight is vacant. Three vacant divisions out of five total women's divisions is an alarming ratio. The women's bantamweight is held by Jennifer Maia — a name that was once a UFC title challenger, now competing in Invicta. The women's atomweight belongs to Ferreira.

What do three of five vacant belts say? It could signal multiple situations at once. First, a slowdown in title-fight scheduling — common for organizations with limited budgets. Second, personnel erosion — female fighters are not numerous, and each time a few leave or suffer long-term injuries, a division empties. Third, a transitional state before a major event.

What is noteworthy is Invicta's role as a "safety net" for female labor in MMA. When UFC cuts or releases a female fighter, Invicta is often where she lands. This stabilizes the women's labor market at the lower tier and keeps female fighters' career paths from being completely blocked when a major organization lets them go. This is a rarely mentioned but vitally important function.

The Contrarian Angle: Belts Are Not Equivalent, and Fans Are Being Misled

Here, I want to devote a whole section to what I consider the most serious misunderstanding in the MMA fan community. It is the belief that a belt in one organization has equivalent value to a belt in another, as long as they share a weight-class name.

That belief is structurally wrong. And it is wrong for three reasons.

First, differences in weight boundaries. As I presented above, ONE's weight-class system is shifted about twenty pounds relative to UFC and PFL. A ONE middleweight champion competes at 205 lbs, while a UFC middleweight champion competes at 185 lbs. These two fighters, if placed on the same mat, could not compete in the same division without major body-weight adjustment. This means that the title "middleweight" in two organizations does not describe the same physical entity.

Second, differences in the depth of roster quality. A belt is worth only as much as the challenges it faces. If a champion must defend through five top contenders, each capable of winning, the belt's value is far higher than one with only two significant contenders. UFC has the largest number of fighters, and therefore, in most divisions, its depth is also greatest. This is a structural advantage no other organization in the world can match in the short term.

Third, differences in continuity and legitimacy. UFC is the organization the global public implicitly recognizes as where champions are rated most highly. This means a fighter wanting to be recognized as "world number one" in his division usually must prove it in UFC. Whether or not I personally see this as unfair to many talented champions in other organizations, it is a market reality. Legitimacy is not a technical quality — it is a social product, built over decades of promotion and media.

So why are fans so often misled? Because mainstream media coverage tends to blur these differences. When a sports newspaper writes "middleweight champion," it rarely specifies which organization's middleweight. When a television report lists champions, it rarely mentions that ONE's weight system differs from UFC's. The result is that fans, especially new fans, form a mental map that does not match reality.

I do not blame them. I only think that if someone truly wants to understand MMA seriously, the first thing to do is learn to read each organization's weight-class table correctly. Learn to look at a title and ask: which system does this title belong to, at what weight level, and against what roster depth. This is not dry academic stuff. This is about respecting the truth.

People remember goals; I remember the sigh behind the net. It is the same in MMA. People remember the belts; I remember what is left behind those belts — fighters never recognized, divisions forgotten, organizations struggling to survive in the shadow of a giant.

Another contrarian point I want to raise: vacant divisions are not necessarily a sign of decline. In some cases, a vacant belt can be a sign of a healthy transition. The old champion retires, a new generation matures, and the organization deliberately keeps the division waiting until a truly deserving fighter emerges. In other cases, a vacant belt is a sign of illness — injury, contract conflict, or deliberate neglect. The problem is that from the outside, these two situations look identical. And that is precisely why I always write slowly, and always check three times before concluding.

Takeaway: Signals to Listen for in the Time Ahead

I am not in the habit of ending an article with a summary. A summary is for administrative reports. For a martial arts writer, what should be left for the reader is not a list of what has been said, but a few signals for them to follow themselves in the time ahead.

The first signal is how PFL operates its champion army. In the next two years, if PFL's promotional campaigns and events truly generate appeal equivalent to UFC's system, we may witness the formation of a genuinely recognized champion class at the second level. If not, PFL will be merely the home of champions the public never really knows. This is a test of converting a talent list into a brand.

The second signal is the evolution of ONE's weight system. Will ONE continue to maintain its shifted weight system, or will it change to align with international standards? The answer to this will affect fighter mobility across organizations, contract negotiations, and how fans understand titles.

The third signal is the fate of Invicta's women's divisions. Three vacant belts out of five is an alarming number. If in six months those belts remain unfilled, it may be a sign that Invicta's operating model is facing serious challenges. If they are filled with new fighters, that will be a sign that the safety net of women's MMA is still intact.

And the final signal, the most important to me, is about the gaps in UFC. When an organization seen as the center of the sport leaves so many belts vacant, one must ask: is this a sign of a transitional phase, or of a larger change in how this organization operates and allocates resources? I will keep taking notes. I will keep listening. And when I have enough data, I will write. But I will not write in haste.

Because I write slowly to remember for a long time, like a person keeping the rhythm for the whole field. And the field this time is not a football pitch, but an entire MMA ecosystem stretching across continents. Six organizations. More than twenty divisions. Hundreds of fighters. And one single question still hanging in the late night in Nha Trang, as I closed my notebook: when this world has grown this wide, who is truly keeping its heartbeat?

Perhaps that person is not a champion with a belt. Perhaps that person is a fighter quietly training in a small gym in Southeast Asia, never noticed by the media. The quiet star of Nha Trang never goes out — and I believe that is true of many other lands in this world, where someone is breathing, clenching their hands, and waiting for their turn to step forward.
