The MMA Championship Map: Six Vacant Belts and a Weight Ladder Shifted by One Tier

There is a photograph I have kept on my phone for three years now, snapped in a hurry in the changing room corner of a small event in Thu Dau Mot. On the wall hangs a weight-class chart printed on A0 paper, yellowed by humidity. Someone took a correction pen and crossed out three divisions, writing two short words beside them: "vacant". Not because there were no athletes. But because there was no money to stage a title fight.

I thought of that photograph while going back through the championship rosters of the six largest MMA organisations on the planet: UFC, PFL, ONE Championship, Rizin, Invicta FC, and the remnants of Bellator. The list is long, running from heavyweight at 265 pounds down to atomweight at 115 pounds, from Las Vegas to Tokyo, from men to women, from established names like Alexander Volkanovski, Cris Cyborg and Sean Strickland to newer arrivals such as Joshua Van, Carlos Ulberg and Thad Jean. A fairly complete map.

But reading closely, I found six instances of the word "vacant" scattered across that map. And it is those gaps that tell a truer story than any name.

Context: a census of belts

UFC is still regarded as the biggest fight promotion in the world. ONE Championship is the Asia-Pacific powerhouse. PFL absorbed Bellator and now holds belts across six different divisions. Rizin holds the Japanese market with its lighter divisions and super atomweight. Invicta FC is an all-women promotion serving as a landing pad for female fighters.

Rizin alone has a more compact roster: light heavyweight is vacant, lightweight has Nurzhan Nozimov, featherweight has Shaydullaev and Wakamatsu, bantamweight has Sabatello, plus a super atomweight division at 108 pounds — the lightest ladder in the entire system. Solbi Izawa holds that belt. It is a weight class that barely exists in UFC or PFL, where fighters weighing under fifty kilograms are rarely discussed.

Counting roughly, the men's side alone has more than eleven divisions, multiplied across five organisations, producing more than fifty men's belts. Add the women's belts and the figure passes seventy. It is an ecosystem so fragmented that even a ten-year industry observer like me has to reopen his notes every time a name comes up. I keep a small notebook, organised in columns: organisation, weight class, champion's name, date of coronation. Some lines I have had to correct three times in a single year.

What matters is that no organisation recognises another's belt. UFC does not recognise ONE's champions. PFL does not recognise Rizin's. Each belt is a closed world with its own ruleset, its own weight ladder, and its own scoring conventions.

There are applause no one hears, but the fight still needs to be told. And this is where I retell that map differently — not through names, but through the structure beneath the names.

Core: three patterns beneath the roster

When I reordered the entire list, three patterns emerged clearly.

Pattern one: PFL is operating as a second-tier belt collector, not a development pipeline. Look at their champions: Vadim Nemkov, Corey Anderson, Usman Nurmagomedov, Thad Jean, Cris Cyborg. Most came through Bellator or left UFC to join. This is a strategy of acquiring already-established talent, not building from the ground up. The question is not "does PFL have belts" — they have six divisions. The question is whether those belts carry competitive value equivalent to UFC's. PFL itself has yet to answer that with a specific fight.

I watched a PFL card last year, and what I remember most was not the finishing sequence but the silence in the arena. Not loud like UFC. Not empty like a regional show. In between. And in-between is the hardest place to be in this sport.

Pattern two: ONE Championship permits a fighter to hold two belts simultaneously. Anatoly Malykhin currently holds both the light heavyweight and middleweight titles in ONE. Christian Lee holds two others. This is a deliberate commercial choice, not an administrative accident. Champion-versus-champion bouts are among the best-selling formats in MMA. UFC has allowed it too, but rarely lets one fighter hold two belts for long. ONE is the opposite — they treat it as identity.

Pattern three: Invicta FC has four of its five women's divisions vacant. On the surface, that signals a promotion stalling. But thought through, Invicta has always been a landing pad for female fighters leaving UFC. Jennifer Maia, a former UFC title challenger, now holds Invicta's bantamweight belt. It is a talent-recycling channel few name, and fewer still pay to watch.

Contrarian angle: the weight ladder shifted by one tier

This is the detail I believe matters most, and the one most overlooked in every "who is the best" debate.

ONE Championship runs a weight ladder exactly one tier heavier than UFC's. Specifically: ONE's lightweight is 170 pounds, while UFC's is 155. ONE's middleweight is 205 pounds, while UFC's is 185. ONE's light heavyweight is 225 pounds, UFC's is 205. ONE's bantamweight is 145 pounds, UFC's is 135. ONE's featherweight is 155 pounds, UFC's is 145. The shift is consistent across the whole system.

That means when someone says "ONE middleweight champion", they are talking about a fighter roughly twenty pounds heavier than the UFC middleweight champion. Same name. Different body weight. Physically a completely different proposition.

In ten years of observing this industry, I have had to correct younger colleagues many times because they accidentally equated two belts of the same name. It is not their fault. No organisation teaches fans how to read a weight-class table. But it produces a systematic perception bias: viewers rate ONE champions as UFC's equals when they are in fact competing a full tier higher.

And here is what I sense through professional instinct: this tier shift is not a design flaw, but a talent-policy choice. ONE wants its Asia-Pacific fighters to contest titles without undergoing brutal weight cuts before fight night. In exchange, they accept that a ONE fighter moving to UFC would need to drop nearly a full division. That is a real mobility barrier, not a hypothetical on paper.

Injury takes away your legs, but it cannot take away the heartbeat of the fight. And the weight ladder — rarely mentioned — is a form of quiet pressure: it decides which fighters have to torture themselves on the scale before they ever step into the cage. UFC fighters at flyweight, 125 pounds, and women's strawweight, 115 pounds, carry the heaviest cut burden. In ONE, because the ladder is already heavier, that pressure eases in the upper divisions. It is a health dimension no one names, but it exists.

The gaps no one counts

Six vacant belts sit on the list: UFC heavyweight, Rizin light heavyweight, plus three Invicta women's divisions and one other women's belt. Five of the six fall in the women's side or the lighter divisions of smaller promotions.

A vacant belt can have four causes: injury, retirement, sanction, or simply a promotion unable to book the fight. None of us knows the specific reason. But when four of five divisions in one promotion's women's roster sit empty, it is no longer one fighter's personal story. It is a structural problem for an entire branch of the sport.

I once spent a whole evening with a female coach in Binh Duong, listening to her describe how her student had no opponent to fight. Not a weak fighter. Not a lack of training money. Simply no one in the same division to match. The belt sat vacant, and an entire generation waited in silence.

This repeats at global scale. A vacant belt means no main event to sell. No main event means a devalued card. A devalued card means fighters further down the bill struggle to get paid. No one prints that chain on paper, but it runs steadily through the sport.

I am not here to score goals, but to record the people who scored them. To me, a vacant belt deserves mention as much as a newly crowned one.

Signals to watch

Three things I will track in the coming months.

First: whether PFL can stage a fight where one of its champions faces a top UFC-level opponent — they do not need to win, only to share the same cage. If they manage it, their collector strategy has a competitive foundation. If not, they are selling old reputations.

Second: whether ONE continues permitting two belts per fighter or narrows the policy. This signals whether they prioritise pure competition or short-term revenue.

Third: whether Invicta fills at least one women's belt within six months. If not, its landing-pad role is wobbling, and the global women's pipeline loses a buffer tier.

There are fights that do not appear on the scoreboard, but live in how we wait. A championship map does not tell us who is strongest. It only tells us who is being left behind — and in which weight class.

I still have that changing-room photograph. Three years on, three divisions remain empty. But last week, a boy in Binh Duong signed with a lighter-weight promotion. He did not talk about belts. He only asked me, very quietly: "Brother, does my division have anyone to fight?"

The answer, honestly, I do not yet know.
