Roberto Soldic enters free agency after ONE Championship contract ends

"

Roberto Soldic has entered free agency after his ONE Championship contract expired, the 31-year-old veteran announced Friday. The former KSW two-division champion only fought three times under the ONE banner between 2021 and 2025, stopping Dagi Arslanaliev in spectacular fashion (watch here) in his most recent bout after a no-contest against Murad Ramazanov and a loss to Zebaztian Kadestam in previous appearances. “Robocop’s” latest competition was a Sept. 2025 boxing match in Poland, when he knocked out Tomasz Adamek. “Thank you for the journey,” Soldic wrote in a statement posted on social media. “My time with ONE has come to an end as my contract has officially expired. I want to thank ONE Championship from the bottom of my heart for the opportunity and the incredible experience. Every fight, every challenge, and every moment inside the cage has pushed me to become a better warrior and a better person. “I’ve gained more than just fights — I’ve gained knowledge, respect, and memories that will last a lifetime. To my fans, thank you for your unconditional support through every high and low. You are the reason I keep fighting. This is not the end. This is the beginning of what’s next. See you soon.” Soldic had a stellar run in KSW before joining ONE, winning eight of nine bouts and capturing belts at welterweight and middleweight. The sole loss in the KSW was a knockout against future UFC champion Dricus Du Plessis, one he avenged six months later with a knockout to recapture the 170-pound belt.
