Apple TV's hit sci-fi series Silo recently wrapped its third season, with a fourth and final season already scheduled for next summer. According to reporter Sigmund Judge, Apple is working on a spin-off show that could enter pre-production later this year, based on an upcoming Hugh Howey novel centered on events in Silo 40. While Apple has not confirmed these plans and Howey is publicly denying them, one detail suggests otherwise: the Silo sets remain standing nearly six months after filming on season four ended in March.

Typically, sets are deconstructed quickly when a show has no future, making their preservation strong evidence Apple intends to reuse them. Apple has already invested heavily in sci-fi franchises with spin-offs like Star City from For All Mankind and an upcoming Monarch series. Silo has proven to be a major viewership hit, making continued content development a logical strategy for the streamer.
