He relocated to the Netherlands with his mother and elder brother when he was six years old as a result of his parents’ divorce. In order to protect himself from bullying as a kid, Overeem and his elder brother Valentijn began martial arts training.

He entered Chris Dolman’s martial arts school at the age of 15 after Valentijn to train as a combat sports competitor. Initially disliking the sport since he was often defeated by more skilled pupils, Alistair changed his mind after meeting Bas Rutten and Joop Kasteel and began to devote himself totally to training.

At the age of 17, Overeem competed in his first professional kickboxing match under K-1 rules. The next day in March 1999, he faced off against Paul Hordijk and won by decision.

Overeem made his much awaited comeback to PRIDE for his rematch with Antônio Rogério Nogueira. After dominating the first and a half rounds with his striking, Overeem was knocked down by a blow. Nogueira immediately launched a barrage of punches. His corner threw in the towel, fearing Overeem would sustain more serious harm.

At Strikeforce: Carano vs. Cyborg, Overeem was set to defend his first Strikeforce Heavyweight Championship against Fabrcio Werdum. But he was forced to withdraw due to a hand injury, most likely sustained in his nightclub brawl.


Using a standing guillotine choke, Alistair beat Tony Sylvester during Golden Glory’s 10-year anniversary event.


Overeem, along with Fedor Emelianenko, Fabrcio Werdum, Sergei Kharitonov, Brett Rogers, Josh Barnett, Andrei Arlovski, Antônio Silva, and Sergei Kharitonov, were announced as the competitors for the Strikeforce Heavyweight Grand Prix in early 2011.

Overeem was dropped from the promotion’s 2011 Heavyweight Grand Prix. Following his victory against Fabricio Werdum in the quarterfinals on June 18, Overeem continued by saying that he thought the September date was too soon for him to return and that he needed time to relax and recuperate. Daniel Cormier was substituted for Overeem.


Following that, it was revealed on July 29 that Overeem had been discharged from the Strikeforce organisation when Zuffa made use of their authority to revoke the last bout of his contract.


It was discovered that Overeem’s dismissal from Strikeforce wasn’t because he refused to compete in the Grand Prix semifinals but rather because of Golden Glory’s rule mandating that boxers be paid any winnings from contests via their management first.

After considerable speculation, Overeem signed a deal with the UFC. It was announced that his first match would take place in December 2011 at UFC 141. He was scheduled to compete against former UFC Heavyweight Champion Brock Lesnar.

Overeem made his UFC debut against Brock Lesnar in the main event of UFC 141 in December 2011. Early on, Overeem repeatedly struck Lesnar in the body with knees before finishing the contest in the first round. The victory gave him the chance to compete against Junior dos Santos for the heavyweight title.

In May 2012 at UFC 146, Overeem was supposed to square off against UFC Heavyweight Champion Junior dos Santos. But in April 2012, the Nevada State Athletic Commission disclosed that Overeem had failed his PED test before the match. Overeem had a testosterone-to-epitestosterone (T/E) ratio of 14 to 1, which was higher above the permitted ratio rate of 6 to 1. UFC president Dana White announced that Overeem had been replaced by Frank Mir in his bout with dos Santos.

In a prepared statement sent to the media the day before his meeting with the NSAC, Overeem claimed that the positive test result was caused by a doctor-prescribed “anti-inflammatory medication that was mixed with testosterone.”

Overeem returned to face Antônio Silva in February 2013 at UFC 156. Leading up to the match, Overeem was dismissive of Silva’s skills and claimed he was better than his opponent in every aspect of MMA. Despite being a heavy betting favourite and having won rounds one and two, an overconfident Overeem lost to Silva by KO in the third round.

Overeem competed against Frank Mir at UFC 167 in February 2014. He ended up defeating Mir by unanimous decision.

It was later discovered that Overeem tested positive for a prohibited PED in November 2022. The decision was reversed to a No-Contest after a few months when the B- Sample likewise tested positive for PEDs.
