The most reputable MMA organizations are :
- UFC (Ultimate Fighting Championship) 🏆
The largest and most publicized MMA organization. Based in the USA, it brings together the world's best fighters and organizes the most prestigious bouts.
- PFL (Professional Fighters League)
American organization that operates with a regular season, playoffs and finals format, as opposed to the traditional model of one-off fights. In late 2023, PFL (Professional Fighters League) acquired Bellator MMA, ending its existence as an independent organization. In 2024 and 2025, Bellator's top fighters gradually joined the PFL, strengthening its roster and making it the world's second-largest organization behind the UFC. With this takeover, the PFL now has access to a large number of elite fighters and intends to rival the UFC by offering both its regular-season format and super-fights.
- ONE Championship
Based in Asia, it blends MMA, kickboxing and Muay Thai, with a strong emphasis on honor and respect for martial traditions.
