4th Judge

Boxing has long struggled with judging controversies, relying on three human judges whose decisions often spark debate. The 4th Judge is the sport’s first-ever AI-powered scoring system, designed to bring fairness, accuracy, and transparency to the ring. Using real-time computer vision and 103 years of The Ring’s fight data, it tracks landed punches, pressure, and control to generate an unbiased scorecard. Debuting at Usyk vs. Fury 2 and later used in Beterbiev vs. Bivol, it redefined how boxing is judged—data-driven, transparent, and free from bias.
