The creator of One Piece, Eiichiro Oda, has confirmed that the manga is in its Final Saga, which began with the Egghead Island storyline. He initially aimed to finish the manga within three years from the announcement, but complexities in the story could extend this to around 2030. However, there are also reports that Oda officially announced the manga will end in October 2026. Considering the pacing and production factors, the anime adaptation is expected to conclude shortly after the manga ends, likely sometime between 2032 and 2035, but this could be delayed with possible filler arcs or spin-offs. In summary:

• One Piece manga is expected to end between late 2026 (official announcement) and possibly 2030 (extended timeline) depending on pacing and story complexities.
• The anime may end a few years after the manga, around 2032 to 2035.
• Oda has hinted at continued spin-offs and side stories even after the main series concludes.
