Liputan6.com, Jakarta - On May 31, 2026, the YouTube world was shocked by the announcement by Olajide Olatunji, better known as KSI, of his decision to leave the YouTube collective Sidemen.
This announcement was made via a video on his personal YouTube channel titled "I'm leaving the Sidemen," ending widespread fan speculation.

This major decision, confirmed by KSI's representatives to the BBC and the Press Association, was not just a joke or a stunt like he has done in the past.
It marked a new chapter for one of the world's biggest content creators, who has been an integral part of Sidemen.
Personal Reasons Behind KSI's Decision
In his video, KSI explained that the decision to leave Sidemen was one of the most difficult of his life.
In a post on YouTube, the content creator said: “This is honestly the hardest video I’ve ever had to make in my life.
“I’ve gone back and forth on this decision for a very long time. I’ve spent months trying to figure out what the right thing to do is.
“But after a lot of thought, I’ve decided that I will no longer be doing Sidemen videos. Today, 31 May, will be my final Sidemen video.
He emphasized that there was no drama or internal conflict behind his decision, but rather a purely personal drive to focus on himself.
The 32-year-old felt "pulled in many directions" over the past few years, making it difficult to find the balance he desired.
Therefore, he felt the need to spend more time with his health, family, and partner.
KSI called Sidemen his "second family," noting that he had been with the group for 12 to 13 years, or nearly half his life.

Following KSI's announcement, Sidemen released an official statement expressing their sadness over JJ's (KSI's nickname) decision to not continue as part of the group.
They acknowledged that this departure "came as a surprise" to them, although they wished KSI the best for his future endeavors.
Sidemen also emphasized that KSI's departure would not change their commitment to continuing to create content, events, and performances for their loyal fans.
The group assured that future plans will continue, and their creative output will not slow down.
The collective, consisting of Simon Minter (Miniminter), Josh Bradley (Zerkaa), Vikram Barn (Vikkstar123), Tobi Brown (TBJZL), Ethan Payne (Behzinga), and Harry Lewis (W2S), has 23 million subscribers on its main YouTube channel and has launched various ventures such as a fried chicken chain, clothing, alcohol, and cereal.
Background and Fan Speculation
KSI, whose real name is Olajide Olatunji, has been making football, comedy, and challenge videos with Sidemen since 2013.
The announcement came hours after the final of Britain's Got Talent, where KSI served as a judge.
Some fans were initially skeptical of the announcement, considering KSI's previous "leaving" of the group in 2017, which was later revealed to be part of a series of deliberately staged "diss tracks."
However, this time, his departure was officially confirmed, putting fans' doubts to rest.
Despite their departure, both KSI and Sidemen are expected to continue growing independently.
Sidemen themselves plan to continue their expansion on YouTube and major streaming platforms like Prime Video and Netflix, signaling the beginning of a new era for both parties.
