Who Is the Current Heavyweight Boxing Champion?

By Sarah Miller · May 29, 2027

The current world heavyweight boxing champion is Oleksandr Usyk, who holds the unified WBA (Super), IBF, WBO, and IBO titles. As of October 2025, he remains the only reigning undisputed heavyweight champion in boxing after defeating Tyson Fury in May 2024.

Who Is the Current Undisputed Heavyweight Champion?

Oleksandr Usyk is the reigning undisputed heavyweight boxing champion, having won all major belts by defeating Tyson Fury in Riyadh, Saudi Arabia, on May 18, 2024. Usyk captured the WBA (Super), IBF, WBO, and IBO titles in a split decision victory, becoming the first man in the four-belt era to hold all major championships in the heavyweight division simultaneously.

Key Achievements

First undisputed heavyweight champion since Lennox Lewis in 2000
Only boxer to win undisputed titles in both cruiserweight and heavyweight divisions
Defeated two top-tier heavyweights: Anthony Joshua (twice) and Tyson Fury
Undefeated in 23 professional bouts as of October 2025

Major Sanctioning Bodies and Titles

The world heavyweight championship is recognized across multiple sanctioning organizations. While Usyk holds four major belts, other organizations also maintain rankings and interim titles:

WBA (World Boxing Association): Recognizes Usyk as Super Champion
IBF (International Boxing Federation): Usyk is the reigning champion

WBO (World Boxing Organization):

WBC (World Boxing Council): Vacant since Fury's loss; no official champion named as of late 2025
IBO (International Boxing Organization): Usyk retains this secondary belt

Organization	Champion	Status	Last Defense	Date

The table illustrates that Oleksandr Usyk holds four of the five major recognized titles, with the WBC belt currently vacant following Fury’s defeat. The WBC has not yet designated a new champion or ordered a unification bout as of October 2025. This makes Usyk the de facto undisputed champion despite the technical vacancy in one organization.

Path to Undisputed Glory

Usyk’s journey to becoming the undisputed heavyweight champion began after his successful reign at cruiserweight, where he unified all four major titles. He moved up to heavyweight in 2019 and gradually climbed the ranks with victories over Derek Chisora, Chazz Witherspoon, and ultimately Anthony Joshua in 2021 and 2022.

Key Fights Leading to Undisputed Status

September 25, 2021: Defeated Anthony Joshua via unanimous decision to claim WBA, IBF, WBO, and IBO titles
August 20, 2022: Rematched and defeated Joshua again by split decision
May 18, 2024: Fought Tyson Fury for undisputed status in Saudi Arabia; won by split decision

The fight against Fury was historic—marking the first time since 2007 (Vitali Klitschko vs. Danny Williams) that two undefeated champions met for a unification bout. Usyk entered as underdog but used superior footwork, ring IQ, and precision punching to edge out the judges’ scorecards.

Future of the Heavyweight Division

With Usyk now undisputed, the heavyweight landscape faces critical questions about mandatory challengers, potential rematches, and the return of retired stars. The WBC has indicated it may recognize an interim champion while organizing a path back to full unification.

Potential rematch clause exists between Usyk and Fury, likely set for early 2026
Dillian Whyte and Zhilei Zhang are rising contenders in the WBC rankings
Young prospects like Jared Anderson and Guido Vianello are gaining traction

Usyk has hinted at retirement after defending his titles once more, possibly opening the door for a new generation of heavyweights.
