Rivalry

What is a rivalry?

A rivalry exists when two fighters face off more than once, or build toward a fight, under circumstances that make the outcome matter beyond the scorecards. Some rivalries grow out of pure competition: both fighters chase the same title or ranking spot, and a matchup becomes unavoidable. Others grow out of personal conflict, sparked by a comment, an incident, or a loss neither side accepted. Many blend both.

What separates a rivalry from an ordinary two-time matchup is stakes that build over time. A rematch alone doesn’t create a rivalry. The second McGregor-Diaz fight mattered because the first one changed how each man was viewed, and the buildup added trash talk and a bottle-throwing incident at the pre-fight press conference. That accumulation is what defines the term, not the number of fights on paper.

Rivalries also shape how a division gets remembered. A single win fades from memory. A rivalry gets replayed in highlight reels and documentaries years after both fighters have retired.

How rivalries form

Most rivalries start in one of a few ways. A ranking or title picture puts two fighters on a collision course. Repeated proximity creates tension even without a specific incident. Sometimes a promotion books a matchup purely for marketing, and real dislike follows once the two fighters start trading words in interviews and on social media. Other times a single moment does it: a controversial decision, a public callout, a confrontation outside the cage. One fight rarely settles that kind of friction on its own.

Media coverage extends the process. Press conferences, weigh-ins, and social media give a rivalry room to build before either fighter throws a strike. A rivalry can also end quickly: an injury, a retirement, or a one-sided rematch often closes the story before fans expect it.

Rivalry vs. grudge match

Fans often use “rivalry” and “grudge match” interchangeably. They describe different levels of the same idea, though. Rivalry is the broader term: an ongoing opposition rooted in competition, personal dislike, or some mix of both. A grudge match narrows that down to something built almost entirely on personal animosity, with little regard for rankings or a title picture.

Every grudge match is a rivalry. Not every rivalry is a grudge match.

	Rivalry	Grudge match
Basis	Competition, personal dislike, or both	Personal animosity specifically
Tone	Can stay respectful	Usually hostile
Example	Stipe Miocic vs. Daniel Cormier	Conor McGregor vs. Nate Diaz
Duration	Can span a career	Often centers on one feud or fight

Types of rivalries in MMA

Not every MMA rivalry looks the same. A few patterns show up again and again.

Competitive rivalries form when two fighters are simply the best in their weight class at the same time, without much bad blood attached. Miocic and Cormier fought three times across two years largely because their records and rankings kept crossing paths, and Miocic closed out the trilogy by winning the final two bouts.

Personal rivalries carry real animosity, sometimes tracing back to an incident outside competition. The rivalry between Khabib Nurmagomedov and Conor McGregor intensified after a 2018 bus attack tied to McGregor’s camp, and the tension carried straight into the cage at UFC 229.

Internal rivalries happen between training partners who compete separately. TJ Dillashaw and Cody Garbrandt trained at the same gym before their bantamweight rivalry turned bitter, a shift that caught fans off guard given their history as teammates.

Manufactured rivalries are built mainly for promotion. A promotion pairs two fighters and pushes a narrative through interviews and matchmaking, and the resulting animosity can be genuine, exaggerated, or somewhere in between.

Why rivalries matter

Rivalries move business numbers, not just storylines. UFC 229, headlined by Khabib Nurmagomedov’s win over Conor McGregor, drew an estimated 2.4 million pay-per-view buys, the highest total in UFC history according to Guinness World Records and reporting from MMA Fighting’s Dave Meltzer. The McGregor-Diaz rematch at UFC 202 sold an estimated 1.65 million buys, edging out their first meeting at UFC 196, which did roughly 1.6 million.

Rivalries can also open doors for an entire division. Ronda Rousey and Miesha Tate’s rivalry ran through two title fights and a season of The Ultimate Fighter, and Combat Press credits it with helping push women’s MMA into the mainstream.

The appeal hasn’t faded. A&E launched a series called UFC Rivals in 2026, built around retired fighters and analysts breaking down the promotion’s defining feuds, a sign that rivalries still draw an audience away from live fight cards.

Common misconceptions

Trash talk doesn’t automatically turn a single fight into a rivalry. Most fighters hype a bout and move on. A real rivalry needs something that lingers: more than one meaningful clash, or a conflict that never gets fully resolved.

A rivalry also doesn’t require the fighters to dislike each other. Georges St-Pierre and Matt Serra’s rivalry started from a title upset rather than personal animosity, and both fighters moved past it once the score was settled.

A rivalry doesn’t need repeated fights to exist, either. Some rivalries stay unresolved for years because the fight never gets made, and the anticipation itself becomes part of the story.

Frequently Asked Questions

Does a rivalry require multiple fights?

No. Some rivalries build for years without a fight taking place, often because scheduling, weight class moves, or matchmaking keeps the two fighters apart.

What’s the difference between a rivalry and a rematch?

A rematch is simply a second fight between the same two people. A rivalry adds stakes, whether from competition, personal conflict, or both, that make the matchup feel bigger than a standard rematch.

Can teammates have a rivalry?

Yes. Training partners sometimes develop rivalries once they compete in the same weight class, as seen with TJ Dillashaw and Cody Garbrandt at Team Alpha Male.

Is a manufactured rivalry the same as a fake one?

Not necessarily. A promotion can build a narrative around two fighters, and real friction can still develop once they start interacting publicly.

What’s considered the biggest rivalry in UFC history by the numbers?

By pay-per-view buys, Khabib Nurmagomedov vs. Conor McGregor holds the record. UFC 229 drew an estimated 2.4 million buys, according to Guinness World Records.
