Early life 
Michael Musumeci Jr. was born in Marlboro, New Jersey on July 7, 1996. Musumeci is of Italian ancestry. He began training Brazilian jiu-jitsu (BJJ) at age 4 along with his sister Tammi at Fatjo's Martial Arts Academy under coach Fernando "Cabeça". When he was 10 his family moved to Florida. While training at various academies, he met brothers Rafael and Guilherme Mendes of Art of Jiu Jitsu (AOJ) during a seminar, starting a long relationship with the brothers and their academy. Starting at juvenile blue belt, Musumeci won IBJJF world championships at every belt level. In 2014 Guilherme Mendes awarded him his brown belt right after his 2014 purple belt world title while on the podium. In 2015 aged 18, Musumeci received his black belt from Gilbert Burns.

Black belt career 
The following year Musumeci won the 2016 Pan American Championship at roosterweight followed by the World No-Gi Championship. In 2016 he switched team joining Caio Terra's association. In 2017 Musumeci won the UAEJJF World Pro at black belt in the 62 kg weight class. In 2017 he won the World Championship in the Lightfeather division. In 2018 Musumeci became World Champion for the second time. Fighting in a lower weight division he won the World Championship two more times in 2019 and 2021.

2021 
Musumeci made his Who's Number One debut on March 26, 2021, where he submitted Marcelo Cohen with an armbar from the triangle choke position. On May 28, 2021 Musumeci returned to WNO, submitting Lucas Pinheiro with a heelhook. Musumeci's third WNO match was against Edwin 'Junny' Ocasio on June 18, 2021, and Musumeci won the bout by unanimous decision. Musumeci was then invited to compete in the inaugural WNO Championships event, taking part in the tournament for the promotion's Lightweight title. Musumeci faced Gabriel Sousa in the opening round and was submitted by north-south choke, removing him from the competition. Musumeci then competed for the inaugural WNO Bantamweight title on October 20, 2021. He submitted Richard Alarcon with a leglock that has since been dubbed 'The Mikey Lock', and won the belt.

Musumeci was scheduled to make his ADCC debut at the 2022 ADCC World Championship after receiving an invite to the event. During the build-up, the promotion staged their first 'Road to ADCC' event on July 17, 2021 where Musumeci faced fellow ADCC 2022 competitor Geo Martinez, beating him 6-0 on points. After the conclusion of the match, both Martinez and his coach Eddie Bravo confronted Musumeci as they exchanged heated words on the mat. He was forced to withdraw from ADCC 2022 as a result of injury, but has since called for a rematch with Martinez regardless. The pair were originally scheduled for a rematch on March 25, 2021, but the match was postponed and did not come to fruition.

At the end of 2021, Musumeci and his sister Tammi both changed gyms and joined Pedigo Submission Fighting to train under Heath Pedigo.
