Why did KSI leave Sidemen? KSI left the group because he wanted to regain balance in his personal and professional life. On May 31, 2026, he announced that he would stop appearing in Sidemen videos, explaining that years of competing commitments had left him struggling to make time for his health, family, and partner.
KSI, whose real name is Olajide Olatunji, stressed that the decision was his own. He also directly rejected the idea that something bad had happened between him and the other members, making his explanation important when separating confirmed facts from speculation surrounding his departure.
When Did KSI Leave the Sidemen?
KSI announced his departure publicly on May 31, 2026, saying that date would also be his final Sidemen video. His announcement followed months of personal consideration, rather than appearing to be an impulsive decision made immediately before the public statement.
The timing made the announcement particularly significant because KSI had been associated with the Sidemen since its beginning. The group was founded on October 19, 2013, according to the Sidemen’s official website, bringing together seven friends who developed one of Europe’s most prominent YouTube collectives.
KSI described the announcement as extremely difficult and reflected on more than a decade spent with the group. He recalled travelling with the members, building projects together, and growing from creators making informal videos into entertainers with a much larger international audience.
What Reason Did KSI Give for Leaving?
KSI’s clearest explanation was that he had become stretched across too many areas of his life. He said he had been running at full speed while trying to meet competing demands, eventually recognizing that his personal balance was suffering as a consequence.
The most important part of his explanation concerned his personal priorities. KSI said he wanted to focus on himself, improve his work-life balance, look after his health, spend more time with his family, and make time for his partner. Those were the reasons he publicly attached to the decision.
His explanation therefore points toward exhaustion and competing responsibilities rather than a confirmed dispute. KSI specifically said, “The truth is, nothing bad has happened,” before describing the departure as a decision he had made himself after considerable thought.
That statement matters because online discussions frequently turn celebrity departures into stories about disagreements or behind-the-scenes conflict. In KSI’s case, the available direct evidence does not establish a major feud as the reason for leaving, so claims beyond his explanation should not be presented as fact.

How Busy Had KSI Become Outside the Sidemen?
KSI’s career had expanded considerably beyond the gaming videos that initially established his online profile. The Sidemen’s official website identifies him as a platinum-selling music artist and YouTube boxing champion, while his career has also included television, business and other entertainment activities.
Television became another major commitment. KSI had previously appeared as a guest judge on Britain’s Got Talent, and ITV subsequently announced him as a full-time judge for Series 19 alongside Simon Cowell, Amanda Holden and Alesha Dixon.
The timing illustrates how different his professional life had become from the Sidemen’s early years. KSI was no longer simply balancing a personal YouTube channel with group videos. He was managing entertainment work across several industries, creating additional demands on his schedule and attention.
His business and sporting interests also contributed to a broader professional portfolio. The Guardian reported in March 2026 that KSI had acquired a minority stake in Dagenham & Redbridge, adding football ownership to an already extensive range of activities outside the Sidemen.
Did KSI Leave Because of a Sidemen Feud?
There is no reliable evidence establishing a major feud as the reason KSI left. His own announcement explicitly said that nothing bad had happened and framed the decision around his personal circumstances, work-life balance, health, family and relationship.
The Sidemen’s public response also did not announce a dispute. In their statement, the group said they were sad to share the news, wished KSI well for his future, and acknowledged that the announcement had come as a surprise to them.
That reaction suggests the departure was not presented publicly as a conventional breakup caused by an established disagreement. The group’s statement did, however, make clear that KSI’s announcement was unexpected from their perspective, adding an element of surprise without providing evidence of a serious personal conflict.
It is important to distinguish surprise from hostility. The Sidemen saying that the news surprised them does not prove that the members were angry with KSI, nor does it establish disagreements that may have occurred privately. Without reliable confirmation, those interpretations remain speculation.
What Did KSI Say About the Other Sidemen Members?
KSI’s announcement was notably appreciative toward Simon Minter, Josh Bradley, Vikram Barn, Tobi Brown, Ethan Payne and Harry Lewis. He thanked each member individually and reflected on how they had experienced major stages of life together during the group’s long history.
He described the Sidemen as a second family and emphasized that the members had supported one another through difficult periods as well as successful moments. His comments presented the departure as stepping away from a major chapter of his life, rather than rejecting the relationships created through the group.
KSI also encouraged viewers to continue supporting the remaining members. He said they deserved someone who could give the group complete commitment and expressed confidence that the Sidemen would continue producing successful content after his departure.
That message is significant because it shows that KSI did not portray the group’s future as something he wanted to undermine. Instead, his explanation was that his own priorities had changed and that continuing to participate without being able to give the necessary commitment was no longer right for him.
How Important Was KSI to the Sidemen?
KSI was one of the seven original members who formed the Sidemen in 2013. The official Sidemen website describes the group as having grown from a group of friends making videos into a collective with millions of fans and billions of views.
The group’s development also moved well beyond ordinary YouTube uploads. The Guardian reported that the Sidemen had produced football, comedy and challenge videos, while their wider business activity included clothing, food and other branded ventures. Their expansion demonstrated how the collective developed into a substantial entertainment brand.
Their history was significant enough to become the subject of The Sidemen Story, a 2024 Netflix documentary looking back at the group’s first decade together. Netflix describes the project as a documentary about the pioneering British collective and its journey through its first ten years.
The Sidemen also expanded into long-form television-style entertainment through Inside, a reality competition series released on Netflix. Netflix identified KSI among the seven Sidemen members involved in the project and reported that the group served as executive producers on its second season.
How Does KSI’s Exit Compare With the Sidemen’s Early Years?
The contrast between KSI’s departure and the group’s beginnings is substantial. In 2013, the Sidemen were primarily a group of online creators collaborating around gaming, comedy and personality-driven videos. By 2026, their work extended into television, streaming, commercial brands, live events and other entertainment projects.
KSI’s own career followed a similar transformation. ITV describes him as a music artist, YouTuber and boxer, while his television work with Britain’s Got Talent added another mainstream entertainment role. His professional identity therefore became considerably broader than that of the creator who initially joined the Sidemen.
This comparison helps explain why his decision can be understood as a question of priorities. The Sidemen had grown dramatically, but KSI’s individual career had also expanded. Maintaining both at the same level of commitment could become increasingly difficult, particularly when he wanted more time away from professional obligations.
What About KSI’s Earlier Sidemen Departure?
KSI’s 2026 exit should not automatically be confused with earlier periods when his relationship with the Sidemen changed or when he discussed leaving. The current announcement is specific: he said he would no longer make Sidemen videos and identified May 31, 2026, as his final appearance.
The distinction is important because older discussions about KSI and the Sidemen can easily be mixed with the current situation. The reliable evidence surrounding the 2026 announcement centers on his personal decision and his desire to restore balance, rather than older controversies or unrelated moments from the group’s history.
For readers researching the question today, the strongest evidence is therefore KSI’s own 2026 statement and the Sidemen’s accompanying public response. Earlier events may provide historical context, but they should not be used to manufacture a reason for the current departure.
What Happens to the Sidemen After KSI’s Exit?
The Sidemen have indicated that they intend to continue. In their response to KSI’s announcement, the group said they had plenty of plans and expressed confidence about the future, although the statement did not establish every detail of how future content would change.
KSI also told viewers that he expected the remaining members to continue creating impressive content. His comments effectively separated his personal decision from the group’s future, suggesting that leaving the videos did not mean he believed the Sidemen project itself had reached an endpoint.
That distinction is important for understanding what his exit actually means. KSI leaving removes one of the collective’s founding personalities, but it does not amount to an announcement that the Sidemen are ending. The group’s own statement explicitly indicated that further projects were planned.
Is KSI Still Connected to the Sidemen?
KSI is no longer participating in Sidemen videos following his announced final appearance on May 31, 2026. That is the clearest confirmed change resulting from his announcement, while the precise nature of any future informal relationship should not be assumed unless KSI or the group confirms it.
His departure also does not erase his historical connection to the organization. He remains one of its founding members and a central figure in its story, with his contribution documented through the group’s decade-long history and projects such as The Sidemen Story.
Whether he eventually appears in a future Sidemen project is a separate question. Unless a specific collaboration is officially announced, it is more accurate to describe KSI as having left regular Sidemen video participation rather than predicting a permanent personal separation from every member or project.
Why Did KSI Leave Sidemen? The Final Answer
The verified answer is straightforward: KSI left the Sidemen because he wanted to restore balance in his life and focus more on his health, family, partner and personal priorities. He said he had spent months considering the decision and felt increasingly pulled in too many directions.
His explanation does not support claims that a confirmed feud caused the departure. KSI explicitly said nothing bad had happened, while the Sidemen described the announcement as a surprise and wished him well. Those statements provide the strongest available evidence about why the separation occurred.
The decision also came after more than twelve years of involvement with a group that had grown from seven friends making online videos into a major entertainment collective. KSI’s expanding career made the question of time and priorities increasingly relevant as both his individual profile and the Sidemen became larger.
Ultimately, KSI’s exit represents a major change for the Sidemen, but it is best understood as a personal decision rather than a confirmed collapse in relationships. His own explanation centers on work-life balance, while the group’s response indicates that the Sidemen intend to continue without him.
