Mateusz Gamrot Bio
Mateusz Gamrot, born on December 11, 1990, in Bielsko-Biała, Poland, is a professional mixed martial artist who currently competes in the Lightweight division of the Ultimate Fighting Championship. Known by the ring name “Gamer,” he is a former Konfrontacja Sztuk Walki Featherweight Champion and a two-time KSW Lightweight Champion. A southpaw with a wrestling foundation and a black belt in Brazilian Jiu-Jitsu, Gamrot has built a reputation as one of the most well-rounded Polish fighters of his generation. He is currently ranked among the top ten competitors in the UFC Lightweight division.
Early Life and Background
Mateusz Gamrot was born and raised in Bielsko-Biała, a city in southern Poland. He started wrestling at the age of ten and quickly developed a passion for the sport. During middle school, he moved to a boarding school in Milicz to train in freestyle wrestling under more advanced conditions. While studying at a technical school, Gamrot became part of the Polish national wrestling team and earned medals at the junior and youth national championships.
As a 20-year-old, he permanently relocated to Poznań, where he continues to live and train. He began his competitive wrestling career in 2002 and competed in more than 300 matches at the national, European, and World Championship levels. After years of success in amateur wrestling, Gamrot decided to transition to mixed martial arts in 2011, training under Andrzej Kościelski, a former World Wrestling Champion.
Path to MMA
Gamrot’s path toward professional fighting was shaped by a strong amateur wrestling background and a growing interest in submission grappling. In 2012, he captured a gold medal in the 70 kg category at the European Amateur MMA Championships in Brussels, and he successfully defended that title the following year in Budapest. He also won gold at the Polish Grappling Championships in the purple belt division in 2013 and 2014, and in 2014 he won the ADCC Submission Wrestling European Championship at 77 kg.
Those amateur accomplishments helped him transition smoothly into professional mixed martial arts in 2012. With a balanced skill set built on wrestling, striking, and grappling, Gamrot was ready to face seasoned opponents on major European stages.
Mateusz Gamrot Career
Early Career (2012–2013)
Mateusz Gamrot made his professional mixed martial arts debut on February 4, 2012, at XFS Night of Champions, where he defeated Chechen fighter Arbi Shamayev. By the end of that year, he had added two more victories and signed with KSW, one of Europe’s top mixed martial arts promotions. He made his KSW debut on June 8, 2013, at KSW 23, stopping Mateusz Zawadzki via technical knockout.
Later that year, he defeated former UFC fighter Andre Winner by unanimous decision at KSW 24, and followed that performance with a decision win over Jefferson George at KSW 27. Those early results helped establish Gamrot as one of the most promising young fighters in Polish mixed martial arts.
KSW Breakthrough (2013–2019)
Gamrot’s rise through KSW was steady and impressive. After winning his first four fights inside the promotion, he branched out for a brief appearance with Cage Warriors, where he submitted Welsh fighter Tim Newman with a heel hook in the first round at CW 72. Returning to KSW, he strung together additional wins, including a late technical knockout of Rodrigo Cavalheiro Correia at KSW 30 that earned him a Knockout of the Night bonus.
On May 27, 2016, at KSW 35, Gamrot captured the vacant KSW Lightweight Championship by defeating Mansour Barnaoui via unanimous decision in a bout that earned both fighters the Fight of the Night bonus. He successfully defended the title several times, including a heel hook submission of Renato Gomes Gabriel at KSW 36, a unanimous decision win over former UFC fighter Norman Parke at KSW 39, and a keylock submission of Grzegorz Szulakowski at KSW 42. On December 1, 2018, at KSW 46, he added the KSW Featherweight Championship by dominating Kleber Koike Erbst over five rounds, becoming a two-division champion. In May 2019, Gamrot announced he had vacated both titles and would not renew his KSW contract, opening the door to a move to the world’s largest promotion.

He bounced back quickly in 2021, scoring a second-round knockout of Scott Holtzman and a first-round kimura submission of Jeremy Stephens, the latter recognized as the fastest kimura submission in UFC history. Both performances earned him Performance of the Night bonuses.
Gamrot continued his ascent with a technical knockout win over Carlos Diego Ferreira in late 2021 and a hard-fought unanimous decision victory over Arman Tsarukyan in 2022. After a decision loss to Beneil Dariush at UFC 280, he responded with a split decision win over Jalin Turner at UFC 285 and a technical knockout victory over Rafael Fiziev in September 2023. In 2024, he outpointed former champion Rafael dos Anjos at UFC 299, then dropped a split decision to Dan Hooker at UFC 305 in a fight that earned him another Fight of the Night award. In 2025, he defeated Ľudovít Klein by unanimous decision at UFC on ESPN 68, then accepted a short-notice main event against former champion Charles Oliveira at UFC Fight Night 261, where he suffered his first career defeat by finish via second-round face crank. In April 2026, Gamrot returned to the win column with a second-round arm-triangle choke of Esteban Ribovics at UFC 327.
