UFC's nearest audiences span athletes, musicians, actors, reality TV stars, fictional characters, and a beauty brand — a mix that signals a broad, mass-market audience shape rather than a tight sport-specific one.
The shape is flat: the top 10 neighbors range from 0.97 to 0.93, a narrow band with no single dominant pull. Similarity here measures how closely two entities' audiences resemble each other in composition. The three highest-scoring neighbors are all MMA athletes — Jon Jones (0.97), Ronda Rousey (0.97), and Georges St-Pierre (0.95) — which is the expected same-kind cluster. But the cross-kind entries arrive quickly: Bellator MMA (0.95) is the only other Sports-subcategory brand in the top 10, and it's immediately followed by Linkin Park (0.95), a Musicians and Bands entry. FOX Sports: UFC (0.95) and Nathan Diaz (0.94) keep the MMA thread alive, but Iron Man (0.94) — a Fictional Character — and Jeremy Renner (0.94) and Jenni Farley (JWoww) (0.93) round out the ten with no thematic connection to combat sports. Tallying the top 10: four Athletes, one Sports brand, one TV Channel, one Musician/Band, one Fictional Character, one Actor, and one Reality TV Star. No Sports League — UFC's own subcategory — appears among them.
The flat shape and subcategory diversity together indicate an audience that is wide enough to overlap substantially with mainstream celebrity and entertainment fanbases, not just dedicated fight-sport followers.
