How Kayla Harrison became the first athlete to conquer both Olympic judo and UFC

In short: Kayla Harrison is a rare force in combat sports, having transitioned from a historic judo career to dominance in mixed martial arts. As the first woman to secure both an Olympic gold medal and a UFC championship, she has redefined the limits of elite grappling across two distinct disciplines.

Born in Middletown, Ohio, in 1990, Harrison began her journey in judo at age six. Her early career was marked by extraordinary success, including gold medals in the 78 kg division at the 2012 and 2016 Summer Olympics. These victories established her as the first American to win Olympic gold in judo. Her technical proficiency was further recognized in 2016 when she was promoted to a 6th-degree black belt, becoming the youngest person in the United States to achieve that rank.

Following her Olympic tenure, Harrison transitioned to mixed martial arts in 2018. She quickly established herself as a formidable lightweight competitor, winning the Professional Fighters League world tournament in 2019 and 2021. Her grappling-heavy style proved difficult for opponents to counter, leading to a series of dominant performances. In 2024, she signed with the Ultimate Fighting Championship, marking a significant shift in her career path as she dropped to the bantamweight division.

Her momentum continued in June 2025, when she captured the UFC Women's Bantamweight Championship by submitting Julianna Peña with a kimura. This victory cemented her status as a pioneer, making her the first female fighter to hold both Olympic gold and a UFC title. Despite facing setbacks, including a 2026 neck injury that forced the postponement of a highly anticipated bout against Amanda Nunes, Harrison remains a top-ranked contender in the sport's pound-for-pound standings.
