KSI has announced his retirement from boxing during the Misfits Boxing event featuring Essex vs Dapper, but the wording of his declaration has sparked speculation among fans about whether he was retiring himself or simply putting his famous alter ego to rest.
The YouTuber and Misfits Boxing co-founder made the announcement at the Copper Box Arena in London on October 10, 2026. Rather than explicitly declaring that he was retiring, KSI made a statement centred around his well-known boxing nickname, The Nightmare.
“I want to make an announcement. The Nightmare has retired,” KSI said.
He then turned his attention towards longtime rival Jake Paul, repeatedly directing an expletive-filled message at the American influencer.
The announcement generated plenty of discussion, with fans debating whether the statement marked the definitive end of KSI’s boxing career or was another dramatic moment from the entertainer.

Fans Question What KSI Meant by ‘The Nightmare Has Retired’
KSI’s choice of words became a talking point because he referred specifically to The Nightmare, the nickname he has used throughout his boxing career, rather than explicitly saying, “I’m retired” or “KSI is retired.”
This distinction prompted speculation among fans about whether he was announcing the end of his boxing career or retiring the aggressive persona he adopted to promote his fights.
However, the context of the announcement strongly pointed towards his decision to step away from boxing. KSI had previously discussed retiring from the sport in January 2026, revealing that he had turned down lucrative offers for a potential fight against Jake Paul.
He later clarified in February that he was taking a break from boxing rather than considering himself fully retired, leaving some uncertainty surrounding his future in the ring.
KSI has not competed since his October 2023 clash against Tommy Fury, which ended in a unanimous decision defeat. The result marked the first loss of his influencer boxing career and followed years of high-profile fights against Logan Paul and other opponents.
Whether his latest declaration means the end of his competitive career or the retirement of the character he portrayed inside the ring remains a subject of fan discussion. For now, his announcement signals another significant moment in the career of one of influencer boxing’s most recognisable figures.
