Apple TV Rumored to Develop Silo Spinoff Series
Rumors suggest Apple TV is planning a spinoff of its sci-fi series 'Silo', potentially adapting author Hugh Howey's new book trilogy about Silo 40, with

Apple TV is rumored to be developing a spinoff series set in its dystopian drama 'Silo'. The speculation originates from a social media user who claimed the project could enter pre-production next year.
This aligns with the timeline for the main series, which is reportedly set to conclude with its fourth season in 2027. No official confirmation has been provided by Apple TV or the show's producers.
Rumored Spinoff Could Adapt New Book Trilogy
The rumored television project may find its story in a new book series from 'Silo' author Hugh Howey. Howey has reportedly been working on a spinoff book trilogy centered on Silo 40, a location distinct from the primary Silo 18 featured in the original novels and the Apple TV show.
This new literary timeline would span from before the events of the first book, 'Wool', to after the conclusion of the third book, 'Dust'. A television adaptation would therefore begin long before the story of the main series and extend beyond its finale.
In the original book lore, Silo 40 is referenced as a rogue underground city that managed to sever its connection to the controlling Silo 1. Its inhabitants allegedly discovered the truth about their world long ago and rebelled to avoid a system reset. The books hint that the rebellions and struggles within Silo 40 helped shape events in other silos, including 17 and 18.
How Season 3 May Set Up the Spinoff
The existing television series may already be laying narrative groundwork for this expansion. In the closing moments of 'Silo' season 3, protagonist Juliette commits to saving not only her own Silo 18 but all other silos from Silo 1's control.
This sets up the possibility that in the forthcoming season 4, she could learn about the independent existence of Silo 40. Such a revelation would naturally introduce the setting and conflict for a potential spinoff series.
So far, the Apple TV show has primarily explored only three silos: 1, 17, and 18. The vast network of other underground bunkers remains largely mysterious, leaving ample room for new stories within the same post-apocalyptic world.

While a spinoff focusing on every silo seems improbable, the specific story of Silo 40's early rebellion and sustained independence presents a compelling avenue. If the rumors prove true and the project moves forward, it would expand the franchise's lore without directly repeating the narrative of the original series. The connection to Howey's new books provides a ready-made blueprint for the show's creators.
