Former KSW two-division champion Roberto Soldić has signed an exclusive contract with the UFC to compete in the welterweight division. The Croatian fighter, nicknamed ‘Robocop’, joins the promotion after leaving ONE Championship.

Soldić has revealed that his new UFC contract pays “substantially less” than his previous agreement with ONE Championship. He stated that the move was motivated by a desire for “consistent activity rather than financial gain,” citing difficulty finding opponents during his four-year tenure with ONE. He noted that despite signing a ten-fight deal involving kickboxing, Muay Thai, and boxing, he only competed in three fights. He specifically mentioned that a potential matchup with ONE welterweight champion Christian Lee failed to materialize.

Soldić is set to make his UFC debut against veteran welterweight Khaos Williams at UFC 332 on October 3, 2026, at the Delta Center in Salt Lake City, Utah. Soldić enters the bout with a professional record of 21-4, while Williams holds a record of 16-5. The matchup is expected to pit Soldić’s knockout power against Williams’ octagon experience.
