KSI took to social media to deliver a brutal response to Andrew Tate’s loss to Chase DeMoor in the main event of Misfits Mania on Saturday night. The pair have traded digs since the news in October that Tate had replaced KSI as CEO of Misfits Boxing.

The YouTuber was left fuming about the decision, given he co‑founded the company alongside manager Mams Taylor. Prior to the fight, the 32‑year‑old did not miss out on the opportunity to congratulateAnthony Joshua’s win over Jake Paul, with the British boxer winning after six rounds on X (formerly Twitter). KSI has a long‑running, intense rivalry with Paul, rooted in their early boxing matches involving each other’s brothers.

He then tweeted: “Now I just need an Arsenal win and Andrew Tate to get knocked out and then this will be a fantastic weekend.” Arsenal did in fact win – a 1–0 victory over Everton on Merseyside.

“This is the best weekend I’ve had this year omg [Oh my God],” KSI later tweeted in response to Tate’s loss. To add to the fire, KSI then posted a photo of both Paul and Tate at their lowest following their respective fights, captioned: “Christmas came early,” followed by a crying emoji.

Although Tate is an experienced martial artist with MMA, kickboxing, K1 and Muay Thai bouts on his resume, he hadn’t fought professionally in any discipline for five years and he had never competed in a boxing match.

The 39-year-old made an encouraging start but as time wore on, ‘King Cobra’ began to look as though he was struggling with his cardio. DeMoor took full advantage, rocking Tate with a huge right hand, and the entire complexion of the bout changed from that moment on.

“I’m gonna have to go back, watch the fight, make a decision but Chase deserves his win,” Tate said after the fight. “I’m really happy for him, genuinely. Better to try and lose than to not try at all.”

Tate has since posted several messages on X following his defeat. His first read: “Most men have never felt the sting of defeat because most men have never even tried.”
