The UFC lightweight division has never had more legitimate contenders behind a champion. Islam Makhachev has been the most dominant force at 155 pounds since inheriting Khabib Nurmagomedov’s training system and applying it to the best competition in the world. The challengers behind him are a murderer’s row. Here’s the full 2025 breakdown.
Champion: Islam Makhachev (26-1)
Makhachev doesn’t just win fights. He removes his opponents’ best options, one by one, until nothing is left. His grappling is the most complete in the division — the Dagestani wrestling system that produced Khabib, now applied by its most elite current practitioner. His striking has developed to the point where elite strikers can no longer target him safely from range. He controls position better than anyone at 155 pounds.
His win over Alexander Volkanovski — a man considered one of the five best pound-for-pound fighters on the planet — was the statement performance of his reign. He’s defended against top-five competition multiple times. His only professional loss came years before the title run, and he addressed it comprehensively in the rematch.
The question isn’t whether Makhachev is the best lightweight. He is. The question is what it takes to beat him, and the division has been working on that problem for two years without finding an answer.
#1: Charles Oliveira (34-10, 1 NC)
Oliveira holds the UFC record for submission wins. He is the most prolific finisher at 155 pounds in UFC history, and he fights with an urgency and willingness to engage in exchanges that makes every one of his fights a genuine spectacle. He lost the belt to Makhachev at UFC 280 in a competitive fight — he had Makhachev hurt early — and has remained the division’s most dangerous non-champion contender since.
At 35, Oliveira is in the back nine of his elite career, but he hasn’t declined. A second title shot is legitimate. He’s the only fighter in the division who has demonstrated the ability to put Makhachev in danger.
#2: Dustin Poirier (30-8, 1 NC)
The Diamond. Poirier has beaten Justin Gaethje twice, knocked out Conor McGregor twice, and competed for the lightweight title. His boxing is elite for the division, his durability is exceptional, and his experience level means he’s rarely surprised by anything an opponent throws at him.
At 35, he’s entering the end of his prime window, but he’s still a genuine top-three threat. A Poirier who is right physically and mentally is one of the two or three hardest fights in the division for anyone not named Makhachev.
#3: Justin Gaethje (25-5)
The Highlight. Gaethje fights with the most violence-forward game in the lightweight division — an output-heavy striking approach that has produced some of the most memorable fights in recent UFC history. He won the interim lightweight title, lost it to Khabib, lost to Oliveira in the submission reversal that was one of the most dramatic fights of 2022, and has remained an elite top-five contender throughout.
His BMF title fight against Max Holloway — which he won at UFC 300 — confirmed that he’s still operating at an elite level. The body of work at 35 is legitimate. Another run toward a title shot is entirely within reach.
#4: Beneil Dariush (22-5-1)
Dariush was one of the most consistent contenders in the lightweight division for years before a rough recent stretch stopped the momentum. His complete game — wrestling, submission skills, solid striking — made him a difficult fight for anyone in the division. A reset and a win streak could rebuild his position quickly.
#5: Mateusz Gamrot (23-2, 1 NC)
The Polish Grappling Machine. Gamrot arrived in the UFC with a wrestling and jiu-jitsu background that immediately translated at 155 pounds. His pressure game, takedown volume, and cardio make him a nightmare for fighters who want to keep the fight standing. He’s built a genuine case for a top-three ranking through performance and is one of the more interesting title shot candidates in the next twelve months.
#6: Arman Tsarukyan (22-3)
Tsarukyan fought Makhachev early in both of their careers in a bout that Makhachev won narrowly. The development arc since that early loss has been impressive — he’s 6-1 in the UFC since that bout, with the single loss coming to Oliveira. His wrestling and striking combination give him the tools to be a legitimate problem for the top of the division. A run at the title from here is not a stretch.
#7: Dan Hooker (24-13)
The Hangman has been a fixture of the lightweight contender pool for years — a durable, dangerous striker who fights with reckless commitment and has produced some of the most entertaining lightweight fights of the past five years. His record shows losses to elite competition, but he’s beaten elite competition too. He’s the division’s wild card.
#8: Michael Chandler (23-9)
Chandler arrived in the UFC from Bellator as a three-time Bellator lightweight champion and immediately made the highest-level competition look difficult in the right way. He’s been finished by the best in the division and he’s had his own spectacular finishes — his spinning back kick KO of Tony Ferguson remains one of the most dramatic finishing sequences in recent lightweight history.
His fight with Conor McGregor has been in various stages of negotiation for years. Whatever that bout eventually produces, Chandler at his best is still one of the most entertaining heavyweights at 155 pounds.
#9: Renato Moicano (18-5-1)
Moicano has been steadily building a case for a higher ranking through performances that exceeded expectations against tough opposition. His jiu-jitsu background gives him a finishing threat that opponents have to account for throughout all three rounds.
#10: Bobby Green (30-14-1)
Green is the journeyman who belongs in the top ten because he keeps beating the fighters ranked just below him. His boxing and movement are genuinely elite for the division, and he’s been a legitimate measuring stick for younger contenders coming up. He’s not a title contender, but he’s a legitimate gatekeeper and consistent top-ten fighter.
Division Outlook
The lightweight division’s hierarchy is unusual because it’s simultaneously clear and deep. Makhachev is the clear best fighter in the division and possibly the sport. Behind him are Oliveira, Poirier, and Gaethje — three fighters with legitimate title fight credentials who could each realistically challenge for the belt.
The next layer — Gamrot, Tsarukyan, Dariush — is pushing hard toward that top three. The movement in the rankings over the next year will come from that group, and whoever emerges from it with the right sequence of wins gets the next title shot after the Makhachev-Garry fight clears.
For Makhachev, the question is what the ceiling of his reign looks like. He’s already dominant. The question is whether he’s building toward a legacy that puts him alongside Khabib and GSP as an all-time great, or whether someone in this contender pool finds the specific problem that his game hasn’t solved yet. The division is working on it.
