British YouTube star and entrepreneur KSI has announced he is stepping away from Sidemen after 13 years, bringing one of the internet’s most recognizable creator partnerships into an uncertain new chapter. The announcement was made on May 31 through an emotional video posted to his YouTube channel, where the 32-year-old creator told fans it had been “the hardest video” he had ever made and confirmed that his latest appearance would be his final Sidemen video for the foreseeable future.
KSI, whose real name is Olajide Olatunji, helped launch the Sidemen in 2013 alongside fellow creators Simon Minter, Josh Bradley, Tobi Brown, Ethan Payne, Vikram Barn and later Harry Lewis. What began as a gaming-focused collaboration among friends quickly grew into a digital entertainment empire. Over the years, the group became known for football challenges, large-scale travel videos, reality content, live charity matches and comedy skits, while building a fan base stretching far beyond YouTube. Their main channel alone has attracted tens of millions of subscribers, and the group has expanded into multiple spin-off channels and streaming productions.
The Sidemen also evolved into a major business brand. Beyond online content, the collective expanded into merchandise, books, food ventures and commercial partnerships. Industry estimates in recent years have placed the group among Britain’s most financially successful digital creators, with combined wealth reportedly running into tens of millions of pounds. Their influence has also crossed into mainstream entertainment, with projects on streaming platforms and sold-out public events further cementing their position as one of YouTube’s biggest creator collectives.
Explaining his decision, KSI said the move was not driven by conflict inside the group but by a need to regain balance in his life. According to reports, he told viewers he had spent months thinking about the decision and ultimately felt unable to continue giving the group the time and energy it deserved while balancing his expanding personal and professional commitments. In recent years KSI’s profile has grown beyond YouTube through music releases, boxing ventures, brand investments and television appearances, including his role as a judge on Britain’s Got Talent. He reportedly said the Sidemen had become “a second family” and emphasized that leaving was deeply emotional rather than a fallout.
The announcement triggered an immediate wave of reactions online. Fans across social media described the news as “the end of an era,” with many sharing clips and memories from classic Sidemen videos. Fellow creators and streamers also expressed surprise. Online discussion, however, has included skepticism, with some fans questioning whether the announcement could be linked to an upcoming Sidemen video or an elaborate prank, something that has precedent in the group’s history. Reddit threads and fan communities quickly filled with debate, with some taking the statement at face value while others argued it may be temporary or tied to content planning.
For the remaining six members, the immediate future remains closely watched. Publicly, the Sidemen brand has not indicated any pause in content production, and several media outlets report that upcoming projects are still moving ahead. Whether KSI returns for guest appearances later or fully separates from the collective remains unclear. What is certain is that his departure reshapes one of the internet’s most successful creator partnerships and signals another shift in how digital stars manage growing careers across entertainment, business and mainstream media.
For many longtime viewers, KSI’s exit feels larger than a routine creator update. The Sidemen helped define a generation of YouTube entertainment in the UK and globally, turning internet personalities into mainstream celebrities and businesses. After more than a decade of viral moments, charity events and entrepreneurial growth, KSI stepping away marks the close of a major chapter, not just for the group, but for the platform culture they helped build.
