IBO computerised ratings
IBO heavyweight rankings
The IBO’s current heavyweight ratings in full. Where the other four bodies publish fifteen names, the IBO publishes 100, produced by computer rather than by a ratings committee. The IBO heavyweight title is currently vacant. Oleksandr Usyk is rated first among the contenders at 25-0. This month 11 fighters moved up the table and 6 entered it for the first time.
