Six Thrones, One Power Map: Why Global MMA Has No Undisputed Champion

Three in the morning, Vietnam time, while most domestic combat sports fans were asleep, I sat before a screen watching a UFC event with the men's heavyweight title left vacant. In the online comment section, one account raised a deceptively simple point: if the ONE Championship middleweight champion moved to the UFC, where would he rank? I typed a reply, deleted it, typed again, then locked the screen. I had enough data. In the end, a satisfactory answer simply does not exist — because the current structure of the MMA world does not allow it to exist.

I have followed combat sports since my high school days in Binh Duong, through long nights watching international events on shaky connections, to becoming a deep-dive commentator on martial arts and esports. Along that path, one paradox kept repeating: the more fans love this sport, the more easily they believe in something that does not exist. They believe in a single "world MMA champion." That belief is nourished by media, not by the actual structure of the sport.

Through long nights with faraway events, I gradually understood why people choose to cry for a fighter — and also why they easily confuse one throne with another.

A map of six kingdoms

If you redraw the current global MMA power map, you will see a clear hierarchy. At the top sits the UFC — considered the largest organization in the world, with titles stretching from a 265-pound men's heavyweight limit down to a 115-pound women's flyweight. Alongside it is ONE Championship, the Asia-Pacific powerhouse with a completely different weight-measurement system. The second tier includes the PFL — currently restructuring after absorbing Bellator — and Rizin, the Japan-rooted promotion with a strong regional identity. At the specialized tier, Invicta FC operates as a women-only system, serving as a launchpad for female fighters before they ascend to larger arenas.

Each organization holds exclusive contracts with its fighters, maintains its own rankings, and — most importantly — runs its own weight-class ladder. A rough count shows that the five major organizations together produce more than 55 men's titles across all weight divisions. Adding women's divisions, the fragmentation of titles far exceeds any team sport. In football, there is one World Cup champion. In MMA, there are dozens of "world championships" claimed by different organizations, and none of them recognize each other.

This structure is an inevitable consequence of the business model: an organization can only sell tickets and broadcast rights if it owns exclusive champions no one else has. Titles across different organizations cannot be directly compared, either in physical terms or in weight-class structure. A UFC "middleweight" belt and a ONE "middleweight" belt represent two different body weights, two different training ecosystems, and two different talent pipelines.

The measurement shock: when ONE raises the throne

This is the technical detail most overlooked in Vietnamese fan debates: ONE Championship runs a weight-class ladder shifted approximately 20 pounds heavier than the UFC. More specifically, ONE's light heavyweight limit is 225 pounds, while the UFC — and most other organizations — set 205 pounds. ONE's middleweight is 205 pounds, while the UFC sets 185. ONE's welterweight is 185, UFC is 170. ONE's lightweight is 170, UFC is 155. ONE's featherweight is 155, UFC is 145. ONE's bantamweight is 145, UFC is 135. ONE's flyweight is 135, UFC is 125. ONE's strawweight is 125 — a division that in the UFC exists only on the women's side. And at the very bottom, Rizin's super atomweight sits at 108 pounds.

Place two belts of the same name on the scale, and you will find two fighters who can differ by nearly an entire weight class when they actually compete. The consequence is that a ONE middleweight champion — competing at 205 pounds — moving to the UFC must choose: either cut nearly 20 pounds to fight at light heavyweight, or add weight to compete at heavyweight. There is no middle path that does not require years of body recomposition.

Strategically, this is a deliberate choice. By placing its entire ladder higher, ONE enables fighters from the Asia-Pacific region — where some markets have larger skeletal frames at middle and heavy weights — to compete at championship level without being forced to cut to extreme limits. This is a form of the organization's labor policy, quietly protecting fighters' health from the brutal cutting pressure that characterizes the UFC's flyweight and strawweight divisions.

I have seen many young Vietnamese fighters at tryouts say they "want to fight in the UFC." When I ask what weight class they are in, they usually answer with a UFC number, unaware that ONE — a closer venue geographically and culturally — measures them by a completely different ruler. That is the awareness gap that domestic media must fill.

PFL and the strategy of assembling second-tier stars

One of the most notable structural moves in global MMA over the past few years is the rise of the PFL. After absorbing Bellator — once UFC's North American rival — the PFL quickly expanded its championship portfolio. Today, the PFL holds belts 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.

What is striking is the composition of this champion roster. Most current PFL champions originate from Bellator or elsewhere, rather than being grown through the PFL's own young development pipeline. This is clearly an acquisition-driven commercial strategy — a way for the PFL to rapidly build a star portfolio capable of competing in media terms with the UFC, rather than waiting for a new generation of talent to mature within its own system.

The scars of transferred champions are always present in every title defense — as they must prove to the audience that their belt is not a "second-tier belt" just because it is worn in a smaller organization. With Nemkov, Anderson, or Usman Nurmagomedov, every title defense is a fateful trial before public opinion — fans ask not only whether he will keep the belt, but also whether he deserves to be ranked alongside UFC champions.

Personally, I believe that question has no conclusive answer, and perhaps that is exactly why it remains compelling. The MMA world exists in a state of comparative suspension — champions of different organizations must operate like stars in separate galaxies, shining within their own frames of reference, never measured by the same ruler. This incommensurability generates endless debate, and that endless debate is itself the fuel that keeps the sport alive.

Invicta's quiet role and the women's labor recycling system

While the UFC and ONE attract media attention, Invicta FC operates as a mesh in the labor network of women's MMA. It is the only organization among the five major promotions to devote its entire belt system to women's divisions. But the more notable fact lies in its functional position: Invicta serves as a waystation for female fighters leaving the UFC.

The case of Jennifer Maia is the clearest example. A former UFC women's flyweight title challenger, Maia is now regarded as one of Invicta's core figures at women's bantamweight. This is not a "downgrade" — it is labor recycling. When the UFC cuts or declines to renew women's fighters, Invicta absorbs them, ensuring they can still compete, still earn income, and still sustain their careers. Without Invicta, the women's MMA labor market would collapse at the bottom — a consequence few consider, but one that directly affects the livelihoods of dozens of female fighters worldwide.

A ballad of unsung heroes — that is how I want to write about Invicta whenever it appears at the margins of big headlines.

Yet Invicta also faces a serious structural problem: four of its five women's divisions currently have no reigning champion. The women's featherweight, flyweight, and strawweight divisions all lack champions, while atomweight has a champion but no clear defense schedule. This prolonged vacancy reflects not only slowdown in matchmaking — it is also a negative commercial signal: an organization unable to fill its titles loses sponsor visibility and credibility in fighter development.

The dual-belt phenomenon and ONE's strategic identity

If there is one uniquely distinctive trait in how ONE Championship operates, it is the policy of allowing fighters to hold two championship belts simultaneously. Anatoly Malykhin currently holds both the light heavyweight and middleweight men's titles in ONE. Christian Lee is another case, holding two belts in two different divisions.

Structurally, this opens something the UFC restricts far more heavily: "champion versus champion" fights become a recurring annual format rather than a rare treat. Because contract structures allow a fighter to hold two belts, ONE can stage more super-fights — each a commercially compelling event for audiences. This is a marketing instrument embedded directly into the institutional structure, and it reflects a philosophical difference between ONE and UFC: UFC prioritizes title scarcity, ONE prioritizes title display.

Tonight, in a bout at Lumpinee Stadium or a stage in Singapore, a fighter can walk in with one belt and leave with two. Combat sports history does not bow — it simply turns another page.

Yet this policy also carries its cost. A dual-belt fighter has less rest time, less injury recovery time, and greater difficulty maintaining peak form in both divisions simultaneously. Malykhin's case — enduring multiple brutal weight cuts to maintain two belts — is evidence of the physical pressure this model creates. This is the blind spot media usually ignores when praising the "dual-belt" achievement — an achievement that is both glorious and quietly risky for long-term health.

Vacancies worth pondering

On the current map, a chain of notable title vacancies appears. The UFC has vacant men's heavyweight and women's flyweight belts. Rizin has a vacant men's light heavyweight belt. Invicta has four vacant women's divisions. These vacancies are not simply administrative news — they are signals about the transitional state of weight-class systems.

For the UFC, a vacant heavyweight belt usually reflects one of several scenarios: champion injury, contract-negotiation deadlock, or an imbalance among contenders that discourages the organization from booking a title fight. For smaller organizations, vacancies often reflect resource problems: a shortage of qualified fighters to fill the slot, or stagnation in matchmaking.

More notably, the vacancy phenomenon concentrates mostly in women's divisions and lighter men's divisions of non-UFC organizations. A reasonable hypothesis is that these divisions have slower matchmaking cycles, thinner talent pools, and lower commercial pressure than heavyweight men's divisions at leading organizations. If the MMA world wants to develop sustainably as a whole, lower-tier divisions need more investment — otherwise they will continue to be treated as "secondary arenas" and continue to fall into prolonged vacancy.

Contrarian angle: the illusion of equivalence

This entire structure leads to what I consider the most important conclusion of the analysis: fans are being led by an illusion of equivalence between titles. When one organization declares a "middleweight champion," and another declares a "middleweight champion," both are treated by media as if directly comparable. They are not.

First, weight measurement differs by about 20 pounds in most divisions. A ONE "middleweight champion" weighs 205 pounds when competing — the number the UFC reserves for light heavyweight. Placing those two fighters on the same conceptual scale is like comparing two bears in two different cages with different cage sizes.

Second, opponent quality differs. A champion in a smaller organization may have defeated opponents who in the UFC would be merely mid-tier. That does not mean he is weak — it means he has not yet been tested at the highest opponent tier. The PFL, whose champions mostly come from Bellator, sits in this position: its belts carry value within the PFL system, but comparison value against the UFC remains an unanswered question.

Third, ranking systems are isolated. A number-one fighter in ONE is not automatically number one in the UFC. Organizational ranking systems do not communicate, share data, or recognize each other. This is an administrative barrier, not a technical one — but its practical effect is entirely equivalent: the world's best fighters may never be placed against each other.

Exclusive contracts are the fourth barrier, and perhaps the hardest. No case in the current listing shows a fighter holding belts in two different organizations simultaneously. The inter-promotional "super-fights" fans dream of — say, the UFC champion versus the ONE champion — currently exist more as contractual fantasy than practical possibility. Unless organizations change their structural philosophy, those fights will remain forever on the "what if" list.

A champion is measured not by the belt but by the streak of days

What I draw from this entire map is not a critique of the current model — but a new way of seeing championship value. A champion's true value lies in the length and quality of the streak of days during which he holds that position within his system, not in the number of belts. For MMA fighters, this criterion becomes even more important, because the number of title fights per year is usually very small — sometimes just one.

A champion who holds a belt for three years in a second-tier organization may have a greater career than a champion who holds a belt for six months in the UFC. Not because his belt is bigger — but because he has proven long-term durability, which the UFC system, with its media pressure and dense fight frequency, sometimes does not permit.

Viewed through this frame, several champions become especially admirable. Xiong Jing Nan of ONE is a prime example: she held the women's atomweight title — and later the women's strawweight title — for an astonishing stretch, enduring multiple generations of challengers. Alexander Volkanovski of the UFC held the men's featherweight belt through one of the division's most competitive eras. Cris Cyborg, regardless of organization, has always stood atop women's featherweight MMA — with a career spanning decades and titles across multiple promotions.

Conversely, some emerging young champions — Joshua Van in the UFC, Carlos Ulberg, Thad Jean in the PFL — still have entire careers ahead to prove that their title moment is not a fleeting peak. I write about them with excitement, but also with the caution of someone who has seen many young champions burn themselves out under the pressure of maintaining position.

Closing: a map without a center

From an arena in Tokyo to a cage in Las Vegas, every battle strums its own ballad. Today's global MMA is a multipolar system with no single center. The UFC is the largest pole, but not the only one. ONE is the Asian pole. The PFL is the acquisition pole. Rizin is the local Japanese pole. Invicta is the women's labor-protection pole. Six kingdoms, six frames of reference, dozens of thrones — and no one recognizes another's king.

For Vietnamese combat sports fans, understanding this structure is the first step toward not being led by superficial comparisons. When you watch a title fight in any organization, ask yourself: within which frame of reference is this champion defending his title? Where does his opponent come from? How many pounds does this belt represent under the international standard? Those questions will turn you from a passive viewer into an analyst with tools.

There are nights you do not need sleep because another's dream is bright enough to keep you going. And there are thrones that need not be compared with other thrones to shine in the hearts of loyal fans. The only thing I hope for MMA in the coming years is greater structural transparency — so viewers know exactly what they are watching, and so truly deserving champions are recognized for the value they create, not merely for the brand name on the contract. Because in the end, a belt is just metal — but a durable career is something no brand can take away.
