Undefeated records
Undefeated MMA Fighters: Who Is Still Perfect?
The greatest undefeated record in MMA history is Khabib Nurmagomedov's 29-0, and it is still standing. 2026 has been a bloodbath for everyone chasing it: three perfect records have already died this year. Four fighters with 15 or more wins are still unbeaten, and our simulation says exactly where their runs are most likely to end.
The greatest undefeated record in MMA history
Khabib Nurmagomedov retired in October 2020 at 29-0, and the number has not moved since. Thirteen of those wins came in the UFC, three of them defending the lightweight title, and he never lost a round to anyone who mattered, let alone a fight. It is the high-water mark of the sport, and the fact it stops at 29 rather than 30 is the reason this whole site exists.
Boxing has bigger numbers. Floyd Mayweather retired 50-0, Rocky Marciano 49-0. MMA does not work that way: four-ounce gloves, a sport where one scramble or one clipped chin ends five years of work, and matchmaking you do not control. Which is why the list of men who have ever gone deep into an unbeaten run is short, and why it gets shorter every year.
Undefeated UFC fighters still standing
Here is every undefeated fighter on the UFC roster with 15 or more professional wins, as of July 2026. This is the honest version of the list: no prospects with four fights, no padding.
| Fighter | Record | Division | Where they are |
|---|---|---|---|
| Movsar Evloev | 20-0 | Featherweight | The leader. Took Lerone Murphy's 0 in London in March, in a fight with the biggest combined undefeated record in UFC history. |
| Shavkat Rakhmonov | 19-0 | Welterweight | Finishes everyone he meets. A knee injury has cost him most of 2026, which is its own kind of threat to a 0. |
| Michael Morales | 19-0 | Welterweight | Ranked top three at 170 and climbing. The least-discussed name on this list. |
| Farid Basharat | 15-0 | Bantamweight | The furthest from the wall, and therefore the one whose record tells us the least so far. |
Note the gap. Evloev is the best-placed man in the sport to chase 29-0, and he needs to win nine more fights in a row, against featherweights who are actively trying to end him, without one bad night in three or four years. That is the whole problem in a sentence.
2026: the year the 0s fell
This has been a brutal year to be perfect. Three of the sport's most-hyped unbeaten records died inside four months:
- Lerone Murphy, March. Lost to Evloev at the O2 in London. The two men walked in with a combined 36-0-1, the largest undefeated total any UFC fight has ever had. One of them had to lose it.
- Khamzat Chimaev, May. Lost a split decision to Sean Strickland at UFC 328, his first defeat in his career, while holding the middleweight title. Thirteen of twenty-four media outlets scored it for Chimaev. It was that close, and it still counts.
- Ilia Topuria, June. Stopped by Justin Gaethje in the fourth round at the White House card, his corner throwing the towel rather than send him out for the fifth with two fractured orbital bones. First loss of his career.
Three men, three completely different ways to lose: outpointed by a veteran, out-hustled by a fellow unbeaten, and physically dismantled. There is no single failure mode. The only common thread is that the level kept rising until it found the thing each of them could not do.
Why undefeated records always end
We simulated 100,000 full careers through our fight engine to find out where unbeaten runs actually die, and the answer was not "gradually". Losses cluster. More runs end at fights 18 and 19 than at any other point, because that is exactly where matchmaking stops feeding you gatekeepers and starts feeding you contenders.
Now look at Ilia Topuria. He went into the Gaethje fight 17-0. It was his eighteenth professional fight. He lost it.
I want to be careful here, because a simulation matching one real result is a coincidence, not a proof. Run it again and the wall might take Evloev at 21 instead. But the mechanism is not a coincidence: unbeaten runs die where the opposition steepens, and in this sport that happens at a fairly predictable depth. Topuria did not lose because he got worse. He lost because he finally met a fight the previous seventeen had not prepared him for.
Every undefeated fighter is undefeated until the exact moment he is not, and the sport gives you no warning which night it is. That is what people miss about the 0. It is not a measure of how good you are. It is a measure of how long you have been lucky as well as good. Khabib retired before the sport got to ask him again.
Can anyone actually break 29-0?
Evloev is the only active fighter with a realistic path, and "realistic" is doing heavy lifting. Nine more wins at featherweight, a division with Volkanovski's shadow over it and a queue of finishers, while staying healthy into his mid-thirties. Rakhmonov might have been the better bet a year ago; a knee has taken most of 2026 off him, and layoffs kill runs as reliably as opponents do.
Our simulation puts a perfect 30-fight run at roughly 1 in 108 even for a sharp operator with an elite camp. Real fighters do not get to re-roll. My honest read: 29-0 survives another decade, and the most likely way it ever falls is not someone beating the number, but someone retiring early enough to keep theirs, exactly as Khabib did.
If you want to see how the numbers behave, we have the full breakdown in is a 30-0 record possible in MMA, and the ratings behind all of it are set out in how we rate fighters.
