Who Is the Boxing Heavyweight Champion in 2025?

By Sarah Miller · November 19, 2050

The current boxing heavyweight champion is Oleksandr Usyk, who holds the unified WBA (Super), IBF, WBO, and IBO titles after defeating Tyson Fury in May 2024. Anthony Joshua is set to challenge Usyk for these belts in a rematch scheduled for December 2025.

Who Is the Current Boxing Heavyweight Champion?

Oleksandr Usyk is the reigning unified heavyweight world champion as of October 2025. The Ukrainian southpaw captured the WBA (Super), IBF, WBO, and IBO titles by defeating previously undefeated Tyson Fury via split decision on May 18, 2024, in Riyadh, Saudi Arabia. This victory solidified Usyk's status as the lineal and recognized unified champion in one of the most competitive eras in heavyweight history.

How Did Usyk Become Champion?

Usyk entered the fight as the defending WBA, WBO, and IBF titlist after previously unifying the division by beating Anthony Joshua twice in 2021 and 2022. However, Fury held the WBC title and was considered the top-ranked heavyweight before their clash. Their unification bout was highly anticipated, marking only the second time in history that all four major sanctioning body belts were on the line in the heavyweight division.

Major Heavyweight Title Holders & Sanctioning Bodies

The professional heavyweight division is governed by multiple sanctioning organizations, each with its own title. While some are more prestigious than others, unifying them increases a fighter’s legitimacy as the true champion.

Sanctioning Body	Current Champion	Date Won	Next Defense
WBA (Super)	Oleksandr Usyk	May 18, 2024	December 2025 vs AJ
WBC	Anthony Joshua	August 3, 2024	TBD
IBF	Oleksandr Usyk	May 18, 2024	December 2025 vs AJ
WBO	Oleksandr Usyk	May 18, 2024	December 2025 vs AJ
IBO	Oleksandr Usyk	May 18, 2024	December 2025 vs AJ

The table illustrates the fragmented nature of modern boxing governance. Usyk holds four of the five major titles, while Joshua won the WBC belt in a rematch against Deontay Wilder after Fury vacated following his loss. This sets up a blockbuster unification rematch between Usyk and Joshua, expected to take place in late 2025.

Key Contenders in the Heavyweight Division

Despite Usyk's dominance, the heavyweight landscape remains deep with talent. Several fighters are vying for mandatory positions or high-profile bouts to earn title shots.

Top Ranked Heavyweights (October 2025)

Dillian Whyte – Former WBC mandatory; working his way back after losses to Fury and Joshua
Joseph Parker – Consistent contender with wins over Andy Ruiz Jr. and Derek Chisora
Agit Kabayel – Undefeated European-based fighter rising in WBC rankings
Jarrell Miller – Returning from suspension; booked for two fights in 2025 to regain ranking
Philo Paz Arboleda – Dark horse candidate with aggressive style and promotional backing

Upcoming Fights & Future of the Division

The heavyweight division is poised for several major matchups in 2025–2026, with unification and legacy at stake.

Scheduled Major Bouts

Usyk vs Joshua II – December 2025, location TBA – Full unification bout
Miller vs Zhang – September 2025 – IBF eliminator
Parker vs Whyte III – November 2025 – WBC final eliminator
Fury vs Dubois – Rematch clause triggered; likely Q1 2026

If Usyk defeats Joshua in their rematch, he may consider retirement or a farewell tour, potentially setting up a dream fight with Deontay Wilder or even a crossover match with a mixed martial arts star. However, his immediate focus remains on cementing his legacy as the best heavyweight of the post-Klitschko era.
