Quick Definition
A vacant title is a championship that currently has no holder, because the previous champion gave up the belt or had it taken away. The next title fight in that division produces a new undisputed champion.
What is a vacant title in MMA?
A weight class has a vacant title when nobody officially holds the championship. The belt exists, the division exists, but the throne is empty. This happens after a champion relinquishes the title, retires, or is stripped of it by the promotion, and it stays vacant until two fighters meet to decide a new champion.
The distinction that matters most is lineage. When a title goes vacant, the chain of “this fighter beat the last champion” is broken. Whoever wins the next title fight starts a fresh reign rather than dethroning anyone. In the UFC, both fighters in a vacant title bout enter as challengers, and the winner walks out as the division’s undisputed champion.
Vacancies are a normal part of how MMA divisions run. Champions move up and down between divisions, and careers end or stall through long injury layoffs. Rather than leave a division frozen with an absent champion, the promotion clears the title and books a fight to fill it.
How a title becomes vacant
Belts reach vacant status through one of a few routes, and the difference between them is usually whether the champion chose to give it up.
Voluntary relinquishment. A champion can hand back the belt on their own. This most often happens when a fighter moves to a different weight class. Jon Jones vacated the UFC light heavyweight title on August 17, 2020, to pursue the heavyweight championship, telling fans he did not want to hold up contenders while he made the move (Sportskeeda). Ilia Topuria vacated the featherweight title in 2025 to move up to lightweight, with UFC CEO Dana White saying Topuria felt he should not block other fighters’ opportunities (Bloody Elbow). Islam Makhachev vacated the lightweight belt the same year to chase the welterweight title (MMA Mania).
Being stripped. The promotion can remove a title against the champion’s wishes. Charles Oliveira was stripped of the lightweight championship in 2022 after he missed weight ahead of his bout with Justin Gaethje, and the belt was then contested as vacant between Oliveira and Makhachev at UFC 280 (UFC.com). Champions can also be stripped for long inactivity or a failed drug test, among other reasons.
Retirement. When a champion retires while still holding the belt, the title empties out. Jorge Masvidal’s retirement in 2023 left the BMF title vacant, and the promotion later rebooked it.
Injury. A long-term injury can empty a title instead of freezing the division around an absent champion. The light heavyweight belt shows how fast this can cascade. Jiri Prochazka won it in June 2022, gave it up months later with a wrecked shoulder, and his replacement Jamahal Hill then vacated the same title in 2023 after an Achilles rupture (CBS Sports).
Vacant title vs. stripped title vs. interim title
Most confusion around the word “vacant” comes from mixing it up with two neighboring terms. They describe different things.
A vacant title is a state: the belt has no holder. Being stripped is one of the actions that can create that state, and it specifically means the title was taken away rather than handed back. A champion who retires or moves up voluntarily also leaves a vacant title, but was not stripped. So every stripped title becomes vacant, though not every vacant title was stripped.
An interim title is different again. A vacancy means the division has no recognized champion at all. An interim title means the division still has a recognized undisputed champion, but that champion cannot compete, so the promotion creates a second, provisional belt to keep the weight class active.
| Term | Is there a champion? | How it happens | What comes next |
|---|---|---|---|
| Vacant title | No | Champion vacates, retires, or is stripped | Two contenders fight to crown a new undisputed champion |
| Stripped title | No, once stripped | Promotion removes the belt involuntarily | Belt becomes vacant and is rebooked |
| Interim title | Yes, plus an interim holder | Undisputed champion is sidelined but keeps the belt | Interim champion aims to unify with the undisputed champion |
What happens to a vacant title
Once a title is vacant, the promotion books a fight to fill it, usually pairing two of the division’s highest-ranked available contenders. The UFC has run vacant title fights many times. Charles Oliveira faced Islam Makhachev for the vacant lightweight belt at UFC 280 in 2022, Alexander Volkanovski met Diego Lopes for the vacant featherweight title at UFC 314 in 2025, and Jiri Prochazka was matched with Carlos Ulberg for the vacant light heavyweight title at UFC 327 in 2026 after Alex Pereira vacated (ESPN).
The winner of a vacant title fight becomes the undisputed champion and begins a new reign. No clause in the Unified Rules of MMA dictates when a title must be declared vacant or who fills it, so the promotion makes that call case by case.
Frequently Asked Questions
Does a vacant title mean the belt was stripped?
Not necessarily. A title can go vacant because the champion retired or moved to another weight class of their own choosing. Stripping is only one way a title becomes vacant, and it refers specifically to the belt being removed against the champion’s wishes.
Who fights for a vacant title?
The promotion typically matches two of the top-ranked available contenders in the division. The winner is recognized as the new undisputed champion.
Can a champion get their vacated title back?
Yes. A fighter who vacates a belt can later fight for it again. Several former champions have reclaimed titles they previously gave up, though they have to win the belt back like any other contender.
Is a vacant title the same as an interim title?
No. A vacant title means the division has no champion at all. An interim title means there is still an undisputed champion who cannot compete, so a second provisional belt is created alongside the existing one.
