This market will resolve to "Yes" if KSI (Olajide Olatunji) officially announces his permanent departure from the Sidemen by December 31, 2026, 11:59 PM UTC. Otherwise, it will resolve to "No."

For resolution to "Yes," there must be an official statement from KSI himself (via his verified social media accounts, official YouTube channels, or credible media interviews) explicitly stating he has left or is leaving the Sidemen permanently. Temporary breaks, reduced appearances, or focusing on solo projects while remaining a member do not qualify.

If KSI takes a hiatus but maintains his status as a Sidemen member, or if other Sidemen members make statements but KSI does not confirm his departure, the market resolves to "No." If the Sidemen group dissolves entirely, this market resolves to "Yes" as KSI would no longer be part of the group.

The primary resolution source will be official statements from KSI's verified social media accounts (@KSI on Twitter/X, YouTube, Instagram) or the official Sidemen channels. Credible reporting from established entertainment news outlets may also be used to confirm the outcome.

If verification becomes unclear due to ambiguous statements or conflicting information by the end time, resolution will be based on the consensus interpretation from credible entertainment news sources. Resolution disputes follow the platform's standard dispute process.
