After 12 Years, KSI Announces His Departure From Sidemen

On May 31st 2026, KSI posted a video to his 18.4 million subscribers titled "I'm Leaving the Sidemen." 

The decision had nothing to do with a disagreement or a falling out. It was much more personal.

Read this quote from KSI and try to fathom this as your life. 

“In the past 10 years, I can count how many times I've seen my parents."

In his explanation, KSI said that staying would not be "fair on the boys or the audience." 

Here’s what you can take from this. 

The creator economy is structurally designed to reward those that say “yes.” KSI co-founded the Sidemen while producing his own content. Then he said yes to boxing. Then he began making music. Then he started a billion dollar business called Prime Hydration. 

All of these commitments contributed to KSI’s status as one of the biggest creators in YouTube history.

But he succeeded so much that he could no longer show up for everything with the same authentic vigor that we know and love.

As much as diehard Sidemen fans hate the decision, this is not KSI’s loss.

If anything, it showed that a living legend was human. And like it or not, that’s something every creator can resonate with.

The late nights. The burnout. The sacrifice.

You have to slow down when the success that was supposed to lead to your freedom is quietly causing the opposite of it.
