The International Boxing Organization (IBO) is a US based corporation that sanctions professional boxing matches and awards world and regional championships.
It is an independent organization not recognized by the "big four" governing bodies (WBA, WBC, IBF and WBO), who only recognize each other in their rankings and title unification rules. Despite this, as of 2023, IBO titles have been unified with titles of the other bodies in several weight divisions. The WBC website highlights the importance of title recognition and the implications of multiple governing bodies in boxing. While the IBO operates independently, its titles being unified with the WBA, IBF, and WBO in certain divisions demonstrates how these organizations work together despite initial rivalries.
