KSI announced he is leaving the Sidemen in a video titled 'I’m leaving the Sidemen' on May 31, 2026. The YouTuber, rapper, and boxer said the decision came after months of thought and was not due to any drama or behind-the-scenes issues. KSI has been a core member of the Sidemen for over 12 years, alongside Miniminter, Zerkaa, TBJZL, Behzinga, Vikkstar123, and Wroetoshaw. The group has not yet issued a formal response beyond the video.

KSI's departure marks a major shift for one of YouTube's most enduring creator collectives. The Sidemen have built a multi-platform empire from gaming videos to merchandise and events, and losing a founding member raises questions about the group's future direction. It also highlights the challenges of maintaining long-term collaborations in the creator economy.
this is a huge shakeup for one of youtube's longest-running groups. the sidemen have been a staple for over a decade, and losing a founder like ksi changes everything. it's a reminder that even the biggest collabs don't last forever.
