KSI Leaving Sidemen Puts YouTube Empire to the Test

KSI leaving Sidemen after 13 years turns a fan shock into a business test. Olajide Olatunji, the British creator, musician and Britain’s Got Talent judge known as KSI, said on May 31 that he would stop making videos with the group to fix his work-life balance, leaving six members to prove the brand can keep its weekly rhythm without its loudest star.

The timing matters. The exit lands after the Sidemen built a channel with about 23 million subscribers, a Netflix reality format, stadium charity matches and a set of consumer brands. A creator collective that began as friends on camera now has to behave like a media company with succession planning.

The Exit Came at Peak Sidemen Scale

The most striking part of the announcement is where it falls on the curve. Sidemen’s official group profile says the group was founded on 19 October 2013 and describes it as Europe’s biggest YouTube collective, a status built through football videos, travel challenges, comedy formats and the recurring comfort of seven familiar personalities.

That familiarity is why fans first treated the announcement like a stunt. The audience has been trained by years of forfeits, fake-outs and group bits to ask whether a serious-looking post is part of the content. This time, the public statements from Olatunji and the group pointed to a real departure, even if the exact shape of his future connection to the business remains less clear.

I will no longer be doing Sidemen videos. Today, 31st of May, will be my final Sidemen video.

Olatunji, a British YouTuber and Sidemen co-founder, said the line in a video posted on the creator’s official YouTube channel. The phrase fans will keep arguing over is simple: he said he would no longer be doing group videos. That leaves space for ownership, friendship and cameos, but it removes him from the weekly engine that made the brand feel alive.

KSI Chose Time Over the Weekly Machine

Olatunji did not pitch the exit as a feud. He said "nothing bad has happened" and described the choice as his own, tied to health, family, his partner and the feeling that he could no longer give the group full attention.

Those commitments are visible. ITV’s full-time judge announcement moved him from guest panelist to a permanent Britain’s Got Talent role for Series 19, putting him on one of UK television’s most recognizable entertainment brands. In March, the Dagenham and Redbridge shareholder announcement named him a shareholder and strategic partner at a lower-league football club with ambitions far beyond its current level.

That matters because Sidemen Sundays are the weekly machine. The main videos are long, location-heavy productions with crews, edits, sponsors and a fan expectation that the same chemistry appears every week. When one member is also a television judge, music act, business founder and football investor, the calendar stops being a diary and becomes a collision map.

The sympathetic read is simple: he chose to leave before the quality of his appearances, or the quality of his private life, slipped further. The harsher read is that the group let one member become so central that his personal bandwidth is now a corporate risk. Both readings can be true at once.

The Remaining Six Inherit More Than a Channel

For Simon Minter, Josh Bradley, Vikram Barn, Tobi Brown, Ethan Payne and Harry Lewis, all Sidemen creators and co-founders, uploading without their most famous partner is the easy part. Keeping viewers from reading every silence, cutaway and team split as an absence is the harder part.

The remaining group inherits a schedule, a company and a commercial promise. The channel has to feel familiar enough to keep the old audience, yet different enough to avoid looking like a tribute act. That is a narrow creative lane.

The table shows why the exit hits differently from a cast rotation on a normal television show. Sidemen videos sell the idea that the audience is watching friendship under pressure. A broadcaster can swap presenters and lean on format. A creator group has to replace the micro-reactions that fans have memorized.

A Studio Push Now Matters More

Several moves over the past two years now look strategically lucky. Netflix’s official media page for Inside, the Sidemen reality series, describes creators competing in challenges for a large cash prize, a format that can travel beyond the core YouTube cast. That matters because streamer formats give the brand a second center of gravity.

A company that makes formats has more room to breathe than a channel whose entire appeal rests on seven friends in one room. It can hire producers, cast guests and build shows where the founders are hosts, judges or executive talent rather than the whole asset.

That shift was already underway before the departure. The public output had been moving toward longer-form shows, bigger locations and more structured competitions. The exit accelerates the question buyers will ask: are they commissioning access to the seven, or are they commissioning a repeatable production method with Sidemen taste?

The answer will show up in credits before it shows up in fan comments. Watch how future shows are billed, who hosts them and whether the thumbnails still depend on founder chemistry. The more the company can sell format first, the less one missing face controls the value of each new idea.

The Brand Portfolio Softens the Shock

The Sidemen were less fragile on May 31 than they would have been five years ago because the income story no longer sits only on video ads. Companies House lists Sidemen Clothing Limited’s company filing as incorporated on 30 December 2014, which is a reminder that merchandise was built into the group early, rather than bolted on after streaming money arrived.

• Clothing turns fan identity into repeat purchases, especially when the channel is quiet between weekly uploads.
• Food and drink brands move the relationship into shops, delivery apps and social posts that do not require every founder to appear.
• Live football events create one-day spectacles where guests, charities and outside creators can carry part of the draw.
• Subscription and streaming formats give the group products that can be scheduled around production cycles rather than weekly improvisation.

That portfolio does not make the exit painless. It does make the group less dependent on a single AdSense curve. The remaining members can now protect the Sunday upload while the wider company leans harder into branded goods, paid formats and live events.

Audience Trust Becomes the Hardest Asset

The obvious danger is that every coming video becomes a referendum. If views hold, the group will claim continuity. If comments obsess over the missing seventh seat, even strong videos may read as transitional. The first few uploads after an exit are less about concept quality than audience permission.

Fans will also watch for tone. A tribute-heavy reset could make the group look sincere but stuck in the past. A cold jump into normal service could protect momentum while irritating viewers who wanted a goodbye. The cleanest path is probably a short acknowledgment, then confident content that does not ask the audience to pretend nothing changed.

Olatunji has left the remaining six with a strange gift. By naming workload and family rather than scandal, he reduced the appetite for a public feud. By leaving at peak scale, he forced the group to answer the only question that matters for a creator company: can friendship become an institution without draining the people who made it valuable?

If the next stretch of Sidemen Sundays feels like a different mix rather than a depleted one, May 31 becomes a succession date. If the rhythm turns cautious, the exit will mark the first real stress test of the creator company era.
