Professional Combat Sports: Why the Richest Fight Business Is the Poorest in Data

Three judges sat at ringside outside the octagon in Newark on June 1, 2026, scoring the lightweight title fight between Islam Makhachev and Dustin Poirier on three different cards: 48-47, 48-47 and 49-46. The fight ended at 2:42 of the fifth round with a submission choke. Had Poirier stayed upright three more minutes, the belt would have rested on three pieces of paper that did not agree with each other.

I watched that fight eleven times. Not to find the choke. I went looking for the data.

The UFC does publish the number of "significant strikes" after the fact. But what makes a strike significant is decided by a person sitting outside the cage, in real time, with their eyes. There is no starting line. No striking velocity. No distance between the two athletes. No motion data released to the public. Eleven replays later, I was holding a pile of unverifiable numbers and three pieces of paper from three human beings.

People call me lucky because of Tokyo? They forget I placed the bet before the opening bell. At the 2026 Olympics I had three weeks and twelve tapes of the Honduras U-23 side. No software, no data vendor. I timed every lost possession on the right flank by hand and went on air predicting 6-0. It came true, and national television in South Korea said my name. But the lesson was not that I am good. The lesson was that this industry is so data-poor that a man rewinding old tapes can still win.

Professional combat sports is a multi-billion-dollar business with the thinnest data infrastructure of any top-tier sport. Football has expected-goals models and positional tracking at dozens of frames per second. Basketball has had in-arena motion tracking since the 2026-14 season. Tennis has had electronic line calling since 2026. In MMA and boxing, what decides the outcome is still a person at ringside pressing a button.

The Unified Rules of Mixed Martial Arts were adopted by the New Jersey State Athletic Control Board in 2026 and later copied by other states and countries. Those rules set four judging criteria: effective striking, grappling, control of the fight, and aggression. The problem is that the order of priority among those four criteria is not consistent across states, countries and promotions. In the same round, one judge may prioritise control, another effective striking, and both can produce opposite scorecards that are both legally correct.

Organisationally, the market splits into three poles: the UFC, ONE Championship and the Professional Fighters League. The UFC signed an exclusive broadcast deal with ESPN starting in 2026, valued by financial press at roughly 1.5 billion US dollars over five years. In 2026, the antitrust class action brought by a group of fighters against Zuffa, the UFC's parent company, was settled for a reported figure of about 335 million US dollars. That number matters not because it is large, but because it is one of the few financial figures this industry has ever been forced to disclose in court.

The UFC's revenue structure rests on two legs: gate and broadcast rights. The share of revenue paid to fighters, according to the antitrust filings, hovered below 20 percent for years. Compared with major North American leagues, where athlete revenue shares typically sit near 50 percent, that gap is not a minor detail. It is the entire story.

On the medical and physical side, the data is even thinner. Body weight is recorded exactly once, at the weigh-in, usually 24 to 36 hours before the fight. The California State Athletic Commission issued weight-cutting regulations in 2026, including specific gravity testing, limits on how much weight can be cut, and pre-fight checks. ONE Championship banned dehydration-based cutting in 2026 and replaced it with urine hydration testing. But no promotion publishes continuous hydration data on its athletes for the public. Which means we know what a fighter weighs at one instant, and we are entirely blind to what that body endured in the seventy-two hours before.

On brain health, the picture is worse. The Chronic Traumatic Encephalopathy research centre at Boston University has published most of the confirmed cases, and those confirmations come after a fighter has died. That means we only learn the extent of damage once the person is gone. There is no blood test, no routine imaging published as an occupational vital sign. A sport whose core product is blows to the head has no longitudinal brain monitoring.

On anti-doping, the UFC partnered with the United States Anti-Doping Agency from 2026. That partnership ended, and from January 1, 2026, another body took over the programme. Changing testing providers is routine in professional sport, but in a discipline where annual sample counts run in the low thousands, the statistical reliability of the doping data was already weak.

The crux is here. In combat sports, data is not missing because it is hard to measure. Data is missing because nobody has an incentive to measure it. A football match carries thirty-two cameras tracking ball and bodies, because the broadcaster sells that data package to bookmakers, clubs and academies. An MMA fight produces no saleable data package, because the only thing it sells is emotion. Emotion does not need coordinates.

I thought I was born to pick fights. Turns out I was born to say what others keep in their throats.

The first consequence is that judging becomes a guided lottery. Several US states have experimented with open scoring, publishing round-by-round cards so fans and fighters know where they stand. Good idea, but it does not fix the root problem: it is still three people pressing buttons, only louder. It does not create data, it merely broadcasts subjective data faster.

The second consequence is that the betting market fills the vacuum. When a promotion does not publish motion data, sports data companies sell their own to bookmakers, and the bookmaker ends up understanding the fight better than the fan who paid to watch it. That is a paradox this industry has never confronted honestly.

Based on my experience covering fights for nearly two decades, I have noticed a pattern: whenever a sport cannot measure something, people measure it with story instead. And story has no obligation to truth. A fighter who wins three pretty fights is called a title contender. A fighter who wins five ugly ones is called boring. No metric contradicts either claim, because the metric does not exist.

Every transfer window is the same: the clever ones analyse, the ones who dare to play win. In combat sports that sentence works in reverse. The ones who dare win because there is nothing to analyse. When contracts, opponents and matchmaking are all decided in one boardroom, every forecasting model is merely a model of the will of the person signing the deal.

But I could be wrong. And I should be clear about where I could be wrong.

The counter-hypothesis is this: ambiguity is not a failure of the industry, it is the product. If the UFC published full motion data, second-by-second scoring and transparent revenue shares, a large amount of argument would evaporate. And argument is what drives fans to buy tickets and click buy on the stream. Modern football is so perfect that sometimes I crave a spectacular mistake. Combat sports never lost the spectacular mistake, and that may be exactly what it sells.

If that hypothesis holds, then all my calls for data transparency are just noise. Promotions do not lack the ability to install sensors. They lack a reason. An opaque scoring system lets them push who they want to push, hide who they want to hide, and always have three pieces of paper to blame.

The second place I could be wrong is about myself. I make a living from judgements built on data, but if tomorrow the data became complete, my job would shrink to reading a spreadsheet. Perhaps I am demanding the thing that would kill my trade, and I have not been honest enough with myself to admit it.

When the stadium went silent, I realised I had never actually heard football. In 2026 the leagues shut down, the press rooms emptied, and the livelihood of a man who trades in hot takes drained within weeks. I was forced to learn how to rewind every phase, count every footstep, cross-reference three past seasons. My career survived not by talking louder, but by looking closer. Combat sports is the same. What is missing is not voices. It is a ruler.

My testable prediction: by the end of 2027, at least one of the three major promotions will publish round-by-round motion-tracking data for every title fight, alongside publicly disclosed scorecards after each round. If that does not happen, the betting market will be the only party holding real data, and fans will pay to watch a performance whose result someone else already calculated. I will bet against myself, because I am used to winning in the uncomfortable way.
