About Mikey Musumeci
Status: Former ONE Athlete
ONE Flyweight Submission Grappling World Champion Mikey Musumeci is arguably the best American-born Brazilian Jiu-Jitsu practitioner in history.
Born into an Italian-American family in 1996, Musumeci started practicing BJJ at age 4 and never looked back. Throughout his childhood, the young prodigy would spend hours before and after school training and drilling jiu-jitsu techniques, typically alongside his sister Tammi, who would become a multiple-time BJJ World Champion herself.
From an early age, Musumeci performed well in competition. After winning numerous IBJJF World Championships at the juvenile and colored belt ranks, he was awarded his black belt at the age of 18.
When he started competing at the highest level of the sport, he quickly found success, winning the first of his five IBJJF Black Belt World Titles in 2016. Three years later, the Italian-American made history with the fastest-ever submission in the final of an IBJJF World Championship when he tapped out his opponent with his trademark straight ankle lock in just 12 seconds.
No longer just a youngster with loads of potential, Musumeci had arrived as an elite, world-class grappler, and soon, he would bring his skills to the world’s largest martial arts organization.
Musumeci made his promotional debut with ONE Championship in 2022, submitting Japanese MMA and grappling legend Masakazu Imanari with a rear-naked choke. That performance earned the American a US$50,000 bonus.
Then, in October of the same year, he made history by winning the first-ever promotional submission grappling crown when he defeated Cleber Sousa for the ONE Flyweight Submission Grappling World Title at ONE on Prime Video 2.
