Justin Gaethje becomes undisputed UFC Lightweight Champion

Justin Gaethje claimed the undisputed UFC Lightweight Championship on June 14, 2026, defeating Ilia Topuria by technical knockout in the fourth round at UFC Freedom 250. This victory marked Topuria's first professional MMA loss.

Gaethje, born in Tucson, Arizona, and raised in Safford, began his combat sports journey in wrestling at the age of four. He achieved significant success in high school, becoming a two-time state champion and graduating with a 191-9 record. His collegiate wrestling career also saw accolades, including a third-place finish at the Oregon Wrestling Classic and a NCAA Western Regional Championship.

Transitioning to mixed martial arts, Gaethje made his professional debut in August 2011. He later joined the Ultimate Fighting Championship (UFC), where he became known for his exciting fighting style. Notably, Gaethje secured an interim UFC Lightweight title by defeating Tony Ferguson in May 2020, ending Ferguson's 12-fight win streak. He also holds the distinction of being the only fighter in UFC history to earn a Fight of the Night bonus in each of his first seven bouts.
