Apple TV has confirmed that *Silo* will return for its fourth and final season on 9 July 2027. The Rebecca Ferguson-led science-fiction thriller follows people living in underground bunkers who begin to question the history and rules governing their lives.

The article says the previous season revealed that the silos are controlled from Silo 1, where a human operator—not an AI—has maintained control for centuries. Juliette and others are trying to defeat that system, while new characters Daniel/Troy, Helen and Charlotte are also described as sensing that something is wrong. Creator Graham Yost has said further revelations remain, including details held back until the final episode.
