The UFC heavyweight division has a two-champion problem — and it’s the most compelling kind. Jon Jones sits atop the throne as the undisputed champion, while Tom Aspinall has held the interim title and done everything asked of him. The unification fight that everyone wants hasn’t happened yet. Everything below both of them is a race for position in a genuinely deep division.
Here’s the full 2025 heavyweight rankings breakdown, with context on every fighter who matters.
Champion: Jon Jones (27-1 NC)
Jones hasn’t fought in over a year, but his claim to the top of the division remains legitimate on record alone. His TKO of Stipe Miocic at UFC 309 was clinical — a performance that showed he still has the tools to handle anyone when healthy and motivated. The question isn’t whether Jones belongs at the top. It’s whether Jones vs. Aspinall ever gets made, and on whose timeline.
At 37, Jones controls the narrative. Every day he delays is a day Aspinall can’t move on. It’s the most consequential inactivity in the sport right now.
Interim Champion: Tom Aspinall (14-1)
Aspinall is the most dangerous heavyweight alive who isn’t Jon Jones. The interim title run has been authoritative — finishing elite competition with striking that is elite for the weight class, submission skills that catch people off guard, and movement that doesn’t belong in a 265-pound body.
His frustration with the Jones situation is legitimate. He’s done the work. He’s beaten the names. The interim belt is real, but the undisputed fight is the only one that counts, and he’s been waiting longer than he should have to.
#1 Contender: Ciryl Gane (12-2)
Gane remains the most technically sophisticated heavyweight in the division not named Jones or Aspinall. His footwork, jab, and range management are in a different tier than everyone else in the top 15. The losses to Jones and Ngannou don’t diminish what he brings — he was the last man to push Jones in a heavyweight title fight before the Stipe performance.
Gane is the natural mandatory challenger if the Jones-Aspinall unification falls through. He’s 32, still improving, and fights with the patience of someone who understands he only needs one opening.
#2: Sergei Pavlovich (18-2)
The most prolific finisher in the current contender pool. Pavlovich’s record in the UFC has been defined by one thing: he ends fights. His KO power is legitimate at heavyweight, and his entry-level striking volume forces opponents into defensive errors that he punishes immediately.
The ceiling question is whether Pavlovich can handle 25 minutes against Aspinall or Gane. His stoppage losses came against elite-level opposition. What he has — violence and finishing instinct — is rare and genuine. A path to a title shot exists if he strings together the right wins.
#3: Curtis Blaydes (17-4, 1 NC)
Blaydes is the archetype of the durable, dangerous heavyweight contender who has been around long enough to beat almost everyone in the division outside the top two. His wrestling base is the best in the contender pool — not as spectacular as some, but consistent and effective enough to win rounds against anyone.
He’s 33, which in heavyweight terms means he’s right in his prime-to-late-prime window. Another big win puts him back in the title picture conversation. He’s never truly gone away from it.
#4: Jailton Almeida (20-2)
Almeida came up through the light heavyweight division and moved to heavyweight without losing any of the athleticism that made him dangerous at 205. His Brazilian jiu-jitsu is elite — top-three submission threat in the current heavyweight division — and his physicality at 265 pounds is something that catches opponents completely off guard at first contact.
He’s still establishing himself against the division’s top names, but the tools are there. His trajectory is one of the most interesting storylines in the heavyweight picture over the next 18 months.
#5: Alexander Volkov (38-10)
Volkov has been a fixture of the heavyweight top 10 for the better part of a decade, and there’s a reason for that. His reach, striking output, and durability have made him a consistent and difficult fight for everyone in the contender pool. He’s not the most exciting fighter on a card, but he wins rounds and he keeps winning bouts.
The veteran ceiling is clear — he’s unlikely to hold a title shot at this stage of his career — but he remains a legitimate gatekeeper and a measuring stick for younger contenders coming up.
#6: Alexandr Romanov (18-2)
Romanov’s ground game is legitimate at heavyweight and his finishing rate reflects that. He’s been steady at the top of the second tier of contenders without breaking through to the very top, but a strong run could change that. The Moldovan has the tools to beat fighters above him in the rankings on the right night.
#7: Derrick Lewis (27-12, 1 NC)
Lewis has been playing at the back end of the top 10 for years, sustained by the fact that his right hand remains one of the most dangerous individual weapons in the sport. The losses have mounted, but so has the legend — no one in UFC history has more knockout wins, and that single fact keeps him relevant in a division where one punch changes everything.
At 39, Lewis is more story than contender at this point. But he can still end fights, and that’s always enough for a spot on a card.
#8: Marcin Tybura (24-8)
Tybura is the definition of a reliable top-10 heavyweight. He doesn’t headline pay-per-views, but he beats the fighters he’s supposed to beat and makes life difficult for the ones who are supposed to beat him. His durability and experience make him a tough out for everyone in the division.
#9: Waldo Cortes-Acosta (12-2)
The Cortes-Acosta prospect hype hit a wall against Volkov at UFC 328, where he was outworked over three rounds and dropped a clear decision. That’s not disqualifying — losing to Volkov isn’t an embarrassment — but it reset expectations on the timeline for this heavyweight prospect.
The physical tools are real. He’s 26, he’s been tested by elite competition now, and he has time to develop. The question is whether the reset was a stumble or a lesson.
#10: Tai Tuivasa (14-9)
The rankings slot here is more legacy than present reality. Tuivasa’s recent run has been rough, and the stoppage losses have piled up. At 31, he’s not old for a heavyweight, but the trend line matters. His ceiling — big swinging power, crowd favourite energy — is unchanged. But a fighter going the direction he’s gone doesn’t belong in title conversations.
Division Outlook
Everything in the heavyweight division sits behind the Jones-Aspinall question. If that fight happens, it reshapes the contender picture immediately. If it doesn’t, Aspinall keeps fighting and the interim title keeps losing meaning by the month.
Below the top two, Gane, Pavlovich, and Blaydes represent the most credible path to a title shot. Almeida is the name to watch as the most physically different threat in the group. Whoever emerges from that cluster in 2025 and 2026 will be the man waiting when the undisputed title picture finally clears up.
The heavyweight division has never had more legitimate contenders. It’s just waiting on the biggest fight to happen first.
