KSI, a prominent social media star and Britain’s Got Talent judge, announces he is leaving the Sidemen, with his final Sidemen video posted on May 31.

He says the move is about prioritizing his health and work-life balance, stressing it is his own decision and not due to any drama within the group.

The Sidemen issue a compassionate statement, saying they’re sad to see him go but will continue producing content, events, and shows for fans.

They also wish him well and tease future projects, acknowledging the adjustment fans will feel.

Confirmation of the departure came through the Press Association amid surrounding rumors that it might be tied to a betting stunt.

Fans initially doubted the news, but social media tributes followed, praising his courage and wishing him success.

Reactions are mixed online, with some seeing it as authentic and others speculating it’s a forfeit or joke linked to Arsenal’s Champions League loss and Sidemen betting culture.

KSI gave personal shoutouts to fellow Sidemen and recalled positive memories from their time together.

At publication, the Sidemen had not announced concrete plans for continuing as a group without KSI.

This marks the biggest Sidemen personnel change since their formation, prompting questions about the group’s future structure and branding.

Other Sidemen publicly thank KSI and affirm their ongoing commitment to future projects, with KSI expressing support for them.

KSI emphasizes the departure is personal, not due to conflict, and says he will support the group from afar while watching their future content.
