Cris Cyborg Wins WIBA 154-Pound Title, First to Hold MMA and Boxing World Belts

The win gives the 40-year-old leverage to chase a Claressa Shields bout before a planned 2026 retirement.

Overview

  • Cyborg captured the vacant WIBA super welterweight crown by first-round corner stoppage at Nação Cyborg 15 in Paraná, Brazil, improving her boxing record to 8-0.
  • The belt from the World International Boxing Association, a boxing sanctioning body, makes her the only fighter holding world titles in both boxing and MMA at the same time as she remains PFL featherweight champion.
  • Right after the win, she publicly offered Claressa Shields $2 million and said she would move up to 160 pounds to box this year.
  • Shields pushed back on social media and has not accepted the fight, which leaves Cyborg seeking a marquee matchup during her stated final year in the sport.
  • The bout ran on Cyborg’s own Nação Cyborg promotion, and outlets listed opponent Paulina Cardona’s record differently, reflecting minor discrepancies in reporting rather than the result.
