Roberto Soldic is a free agent. The 31-year-old fighter announced Friday that his contract with ONE Championship has officially expired, ending a run with the promotion that stretched from 2021 to 2025.
Soldic, known by his nickname Robocop, fought three times under the ONE banner. He stopped Dagi Arslanaliev in his most recent bout, a performance that Yahoo Sports described as spectacular. His other appearances with the promotion included a no-contest against Murad Ramazanov and a loss to Zebaztian Kadestam. His most recent competition of any kind was a September 2025 boxing match in Poland, where he knocked out Tomasz Adamek.
In a statement posted on social media, Soldic addressed his departure and his plans going forward.
"Thank you for the journey," Soldic wrote. "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."
He continued: "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."
Before joining ONE Championship, Soldic built his reputation in KSW, the Polish-based promotion. He won eight of nine bouts there and captured titles at both welterweight and middleweight. His only loss in KSW came by knockout against Dricus Du Plessis, who later became a UFC champion. Soldic avenged that loss six months later with a knockout of his own to reclaim the 170-pound belt.
No announcement about his next promotion or upcoming fight has been made.
