German heavyweight boxer Agit Kabayel has held the WBC interim title since 2025; the sport’s belt reshuffle has spotlighted him as a current, title-holding contender.
British heavyweight Moses Itauma is set to challenge Filip Hrgovic for the vacant IBF title at London's O2 Arena on Aug. 29. A win would make Itauma the youngest heavyweight champion since Mike Tyson as Usyk vacates the unified belts, with supporting matchups and backstories highlighted.
Usyk has vacated the WBA, WBC and IBF heavyweight belts to allow contenders to fight for them, a move that opens the division and sets the stage for new champions. Kabayel has become WBC champion, while Gassiev is poised to inherit the WBA title; IBF actions point toward Frank Sanchez or Moses Itauma as next contenders. The sport faces a reshuffle as Usyk pivots toward a final, high-stakes bout.
