Roberto Soldic Signs with UFC, Set to Compete at Welterweight

Roberto Soldic is a 31-year-old Croatian striker nicknamed "Robocop." He built his reputation in Poland's KSW promotion, where he became a two-division champion, and later had a brief stint in ONE Championship. His professional record is listed as 21-4 with one no contest. Most of his wins are stoppages: 19 of the 21 ended before the final bell, and 18 were knockouts.

Soldic to its official fighter listings, which has been reported by MMA trackers and journalists. The organization has not released an official announcement about a contract signing or scheduled debut, and no opponent or event has been confirmed.

Why this matters to matchmakers and fans

• KSW breakthrough: Soldic first won the KSW welterweight title in 2017 by stopping Borys Mankowski in the first round at KSW 41.
• Loss and rematch vs. Dricus du Plessis: He lost the belt in April 2018 at KSW 43 when du Plessis finished him in round two. Six months later at KSW 45, Soldic reclaimed the welterweight title by knocking out du Plessis in the third round.
• Two-division champ: Soldic later captured the KSW middleweight title, making him a simultaneous two-division KSW champion.
• Notable KSW wins: Mankowski, du Plessis, Krystof Klaczek, Michal Pietrzak, and Mamed Khalidov. His 2021 knockout of Khalidov was one of the signature finishes that raised his profile inside the promotion.
• ONE Championship stint: Soldic fought three times for ONE across more than two years. His most recent ONE win, at ONE 171 in Qatar (February 2025), was a first-round knockout of Saygid Guseyn Arslanaliev at 1:55. ONE's official record lists him at 1-1 with one no contest.

Reports indicate the UFC plans to list Soldic at welterweight (170 pounds) for his debut in the promotion. Matchups and timing have not been announced. Given his style and history of early stoppages, the UFC may pair him with opponents who can showcase his striking or test how his power translates inside the organization's welterweight ranks.

Soldic arrives in the UFC with notable finishing ability and regional championship experience. The move ends a short free-agency phase after his ONE contract expired and gives the UFC another experienced European finisher in the welterweight division. The exact debut event and opponent remain unconfirmed.
