Quick answers

What does MMA stand for?

MMA stands for mixed martial arts, a full-contact combat sport that combines techniques from multiple disciplines — boxing, Muay Thai, kickboxing, wrestling, Brazilian jiu-jitsu, judo and more — into a single ruleset. Rather than restricting fighters to one style, MMA lets them strike standing, clinch, take the fight to the ground and use submissions, all within one contest. The sport grew out of style-versus-style challenge matches designed to test which martial art was most effective in a real fight. The modern answer is that no single art dominates; the best competitors blend striking, wrestling and grappling into a seamless, complete skill set.

Is MMA the same as the UFC?

No. MMA is the sport; the UFC (Ultimate Fighting Championship) is a promotion — a private company that organizes events and crowns its own champions within that sport. The relationship is like the one between basketball and the NBA. Because the UFC is by far the largest and most prestigious promotion, signing most of the world's best fighters, the two terms are often used interchangeably in casual conversation, but they are not the same. Other MMA promotions include ONE Championship in Asia, the PFL, Bellator and Japan's RIZIN, and historically PRIDE and Strikeforce. A fighter can compete in MMA without ever fighting in the UFC.

What martial arts are used in MMA?

MMA draws on a wide range of disciplines, generally grouped by range. For striking, fighters use boxing (punches and head movement), Muay Thai (kicks, knees, elbows and clinch work), kickboxing and karate (kicking and footwork). For taking the fight to the ground, freestyle and Greco-Roman wrestling supply takedowns and takedown defense, and judo adds throws. On the ground, Brazilian jiu-jitsu governs positional control and submissions like chokes and joint locks. Elite fighters do not practice these as separate arts but blend them into one continuous system, transitioning fluidly from a punch to a takedown to a submission depending on where the fight goes.

How do you win an MMA fight?

There are four main ways to win. A knockout (KO) ends the fight when a legal strike renders an opponent unconscious. A technical knockout (TKO) comes when the referee, a doctor or the opponent's corner stops the bout because a fighter can no longer intelligently defend himself. A submission ends things when a fighter taps out to a choke or joint lock, verbally quits, or is choked unconscious. If no finish occurs, the fight goes to the judges' scorecards and is decided by decision — unanimous, split or majority — under the 10-Point Must System. Fights can also end in a draw, a disqualification for fouls, or a no-contest.

Is MMA more dangerous than boxing?

Research suggests MMA produces more visible injuries — cuts, bruises and minor damage — but potentially fewer catastrophic brain injuries than boxing. The key reason is the finish: MMA fighters can win by submission or ground-and-pound, and referees tend to stop fights quickly, so a competitor takes fewer repeated head blows than a boxer who is knocked down, given a standing eight-count and allowed to continue over 12 rounds. MMA's lighter gloves cause more surface cuts but transfer less repeated concussive force than boxing's heavily padded gloves, which let fighters absorb more head trauma over time. Both are inherently risky combat sports, and long-term brain-health concerns apply to each; no combat sport is truly safe.

What are the weight classes in MMA?

The UFC uses eight men's divisions: flyweight (125 lb), bantamweight (135 lb), featherweight (145 lb), lightweight (155 lb), welterweight (170 lb), middleweight (185 lb), light heavyweight (205 lb) and heavyweight (up to 265 lb). There are four women's divisions: strawweight (115 lb), flyweight (125 lb), bantamweight (135 lb) and featherweight (145 lb). Fighters must make their division's limit at an official weigh-in, usually the day before the fight, and title bouts allow no extra weight while non-title fights permit a one-pound allowance. Bouts contested at a weight between divisions, or where a fighter misses weight, are called catchweight fights.

Start with this section - Competitions

MMA has no single global league like the top divisions of soccer or a unified world championship the way boxing pretends to. Instead the sport is organized around promotions — private companies that sign fighters, book cards and crown their own champions — with one giant, the UFC, sitting far above the rest.

The promotions below shaped the sport's history and present. Some, like PRIDE and Strikeforce, no longer exist but defined entire eras before being absorbed. Others compete today for talent and audience across different regions and business models, from tournament formats to season-based leagues.

Competitions

Ultimate Fighting Championship (UFC)

Premier Promotion
Founded 1993Global / USA

The sport's flagship and by far its biggest brand, the UFC crowns the champions widely regarded as the true world's best. Founded in 1993 and rescued from near-bankruptcy by Zuffa in 2001, it grew into a multibillion-dollar business, sold to Endeavor for about four billion dollars in 2016 and folded into TKO Group Holdings alongside WWE in 2023. It runs more than 40 events a year across eight men's and four women's divisions, and its pay-per-views and ESPN deal define the commercial ceiling of the sport.

PRIDE Fighting Championships

Historic Giant
Founded 1997Japan

For a decade PRIDE was the UFC's equal or superior, staging operatic spectacles at the Tokyo Dome and Saitama Super Arena before crowds of tens of thousands. Its ring rules, open-weight tournaments and roster of icons — Fedor Emelianenko, Wanderlei Silva, Mirko Cro Cop, Antonio Rodrigo Nogueira — gave the sport its most romanticized era. Financial and organized-crime scandals crippled it, and Zuffa bought the promotion in 2007, absorbing its stars and ending the sport's split between East and West.

Bellator MMA

Major Promotion
Founded 2008Global / USA

For over a decade Bellator was the clear number-two promotion in North America, built on a tournament format that crowned challengers and later on signing established veterans and prospects. Airing on Viacom's networks, it developed champions like Patricio Pitbull and hosted grand-prix events across divisions. In 2023 the Professional Fighters League acquired Bellator, consolidating the challenger tier of the sport and folding much of its talent into a combined operation.

ONE Championship

Major Promotion
Founded 2011Asia / Singapore

The dominant promotion in Asia, ONE built a broad combat-sports platform spanning MMA, Muay Thai, kickboxing and submission grappling, with a huge regional television footprint. Headquartered in Singapore, it signed marquee talent including Demetrious Johnson and Eddie Alvarez and became a genuine alternative destination to the UFC for elite lighter-weight fighters. Its blend of striking and MMA under one banner reflects the martial-arts culture of its core markets.

Professional Fighters League (PFL)

Major Promotion
Founded 2018Global / USA

Rebranded from the World Series of Fighting in 2018, the PFL introduced a distinctive season-and-playoff structure with a one-million-dollar prize for each division's champion, treating MMA more like a traditional sports league. It expanded aggressively, launching regional leagues and a marquee 'PFL vs Bellator' pay-per-view, and in 2023 acquired Bellator to become the most serious global challenger to the UFC's supremacy.

Strikeforce

Historic Promotion
Founded 2006USA

A California promotion that grew into the UFC's main American rival in the late 2000s, Strikeforce ran on Showtime and CBS and built deep divisions, including the era's leading women's roster headlined by Ronda Rousey, Gina Carano and Cris Cyborg. It also featured heavyweights like Fedor Emelianenko and Alistair Overeem. Zuffa bought it in 2011 and gradually wound it down by 2013, migrating its best talent and its women's divisions into the UFC.

RIZIN Fighting Federation

Regional Major
Founded 2015Japan

Founded to revive Japan's PRIDE-era spectacle, RIZIN stages large New Year's Eve cards blending MMA, kickboxing and open-weight tournaments in the theatrical style Japanese fans embraced. It has hosted returning legends and homegrown stars like Kyoji Horiguchi and cross-over talent, keeping a distinct national scene alive and serving as the spiritual heir to PRIDE's showmanship in the modern era.
