The Global MMA Championship Belt Map: When 'Middleweight' Is Not the Same Measure

A March 2026 evening, I sat in my editorial office in Hai Phong, reviewing footage of the fight between Anatoly Malykhin and Reinier de Ridder at ONE 166. Malykhin won by TKO in the third round, claiming two belts simultaneously - ONE Championship's middleweight and light heavyweight titles. On screen, the statistics displayed accurate strike counts, control time, and takedown numbers. But one figure appeared in no stat sheet: Malykhin's middleweight belt weighs 205 pounds.

The UFC middleweight belt weighs just 185 pounds. This means if Malykhin moved to the UFC, he would face two paths: either cut 20 pounds to fight a division lower, or accept matchups against larger opponents at light heavyweight. This is no small detail. In an industry where every pound is calculated like MMA, the fact that the two largest organizations' weight class systems are offset by one tier is a structural issue that has not been discussed enough.

I have followed international MMA events for many years, and what caught my attention this time was not a specific fight, but the overall map of championship belts. UFC, ONE Championship, PFL, Rizin, Invicta FC - five organizations, over twenty weight classes, and one big question: does the 'world champion' belt truly carry the same value?

The Fragmentation of the Championship Belt System

According to data compiled from the organizations, the UFC currently has vacant men's heavyweight and women's flyweight titles. Rizin has a vacant light heavyweight title. Invicta FC has four vacant women's divisions - featherweight, flyweight, bantamweight, and strawweight. These vacancies are not just scheduling issues. They reflect a reality: even the largest organizations are in transition, with divisions potentially left vacant for months.

The PFL, after absorbing Bellator, holds a wide collection of championship belts: heavyweight with Vadim Nemkov, light heavyweight with Corey Anderson, welterweight with Thad Jean, lightweight with Usman Nurmagomedov, and women's featherweight with Cris Cyborg. Six divisions - a notable number for a non-UFC organization.

But looking deeper into this list, a pattern emerges: most PFL champions originate from Bellator or UFC. Nemkov, Anderson, Nurmagomedov, Cyborg - all were with Bellator before the organization merged into PFL. This is not a talent development system built from scratch, but an acquisition strategy. Data does not betray; we just place our trust in the wrong place - and here, trust must be placed in the question: does the PFL championship belt carry the same competitive value as the UFC belt?

The answer is not simple. Fighters like Nemkov or Nurmagomedov are certainly elite. But their competing in PFL instead of UFC is not just a personal choice, but the result of an exclusive contract system that prevents cross-promotional fights. According to statistics, over 55 men's championship belts exist across different weight classes and organizations. This fragmentation creates a paradox: the more belts there are, the more each belt's value is diluted.

When Weight Classes Do Not Share the Same Measure

Returning to Malykhin's story. ONE's weight class system is designed approximately 20 pounds heavier than the UFC at each tier. ONE's welterweight is 185 pounds - equal to UFC middleweight. ONE's middleweight is 205 pounds - equal to UFC light heavyweight. ONE's light heavyweight is 225 pounds - 20 pounds heavier than UFC light heavyweight.

This difference is not random. ONE operates primarily in the Asia-Pacific region, where some markets have different physical characteristics from the West. Raising the weight class measure allows Asian fighters to compete at championship level without undergoing extreme weight cuts. This is a policy choice - possibly for fighter health, possibly for commercial reasons.

But the consequence is: a ONE middleweight champion moving to the UFC would have to fight at light heavyweight, facing opponents 20 pounds heavier. This is a structural barrier to fighter movement between organizations - a barrier fans often do not recognize when comparing championship belts.

I once witnessed a similar case in Vietnamese martial arts. Years ago, while covering domestic events, I noticed Vietnamese fighters often struggled in international competition due to weight class differences. A 60kg champion in Vietnam might have to fight at 57kg or 61kg in international organizations, depending on regulations. This small difference can create a major advantage or disadvantage in a top-level fight. Numbers tell the story; the storyteller just needs to sit down and listen.

The Double-Champion and Commercial Logic

Malykhin is not the only case of holding two belts in ONE. Christian Lee also simultaneously held ONE's lightweight and welterweight titles. This is a characteristic of ONE: the organization allows - even encourages - fighters to hold multiple belts at once.

From a commercial perspective, this makes perfect sense. A fight between two champions - 'champion vs champion' - is one of the best-selling formats in MMA. ONE can organize more such fights than UFC because of its policy allowing multiple belts. The UFC, with stricter rules about a fighter holding only one belt, has fewer opportunities to create such events.

But this is also a double-edged sword. When a fighter holds two belts, the related divisions are 'locked' - no permanent champion, and title fights become more complicated. That is why the UFC has a stricter policy: to maintain continuity in its divisions.

Invicta FC and the Flow of Women's Talent

Invicta FC is a notable case. The organization is women-only and serves as a 'transit station' for female fighters after leaving the UFC. Jennifer Maia - a former UFC women's flyweight title challenger - currently holds Invicta's women's bantamweight title. This reveals a talent flow: female fighters cut by the UFC or retiring can find opportunities at Invicta, sustaining their careers and income.

This is an important function in the women's MMA ecosystem - where opportunities are significantly fewer than for men. But the fact that Invicta has four of five women's divisions vacant also reflects a harsh reality: even a women-only organization struggles to maintain a stable championship system.

The Big Picture and Lessons for Vietnamese MMA

Looking at the overall map, a clear tiered system emerges. UFC at the apex with its position as the world's largest organization - a claim recognized industry-wide. ONE Championship is the Asia-Pacific power, with its own weight class system and multi-belt policy. PFL is emerging as an ambitious second-tier organization, aggregating talent from Bellator. Rizin holds the Japanese market. Invicta FC plays the role of a 'nursery' for women's MMA.

For Vietnamese MMA, this picture offers both lessons and opportunities. First lesson: weight class systems are not a global constant. Vietnamese fighters seeking international competition need to understand this difference to plan their weight cuts and physical development appropriately. Second lesson: second-tier organizations like PFL or Rizin can be a good stepping stone for Vietnamese fighters before advancing to larger arenas.

The opportunity lies in geography. ONE Championship operates strongly in Southeast Asia and has weight class policies more suited to Asian physiques. A talented Vietnamese fighter may find a path to ONE easier than to the UFC, where lighter weight classes demand more severe weight cuts.

This issue is particularly important for Vietnamese MMA, where female fighters are seeking to assert their position. Currently, Vietnam does not have many fighters competing in major international organizations. But with the growth of LION Championship and domestic events, understanding the structure of international organizations - especially those with weight class policies suited to Asian physiques - could open opportunities for the next generation.

But there is a structural issue to resolve: exclusive contracts. No organization recognizes another's championship belts. A PFL champion cannot fight a UFC champion to determine who is truly number one in the world. This is a limitation of the current MMA business model - and something fans need to understand when comparing fighters from different organizations.

An Unanswered Question

Returning to Malykhin and his 205-pound middleweight belt. In an ideal world, he could enter the UFC, fight the UFC middleweight champion at a neutral weight, and we would know who is best. But the MMA world does not operate that way. Exclusive contracts, differing weight class systems, and each organization's commercial interests create walls that even the best fighters cannot overcome.

That does not mean championship belts have no value. They have value within their own systems. But fans - especially those new to MMA - need to understand that 'world champion' is a relative title, dependent on the organization, weight class system, and timing.

With Vietnamese MMA growing, understanding this global picture is not just academic knowledge. It is the foundation for accurately assessing fighter skill, building sensible development paths, and not being overwhelmed by seemingly grand titles that are actually just part of a much more complex system. When the arena is empty, the loudest applause is your own - and in Vietnamese MMA, that applause must be built on understanding, not blind faith.
