Apple TV releases trailer for Silo season 3, set to premiere July 3

Apple TV has published the official trailer for the third season of the science‑fiction series Silo. The ten‑episode season will debut on July 3, 2026, with new episodes released each Friday through September 4.

The new storyline continues the arc of Juliette Nichols (Rebecca Ferguson), who survives a forced “purge” but suffers memory loss. In parallel, the series adds a centuries‑old “Before Times” plot in which journalist Helen Drew (Jessica Henwick) and Congressman Daniel Keene (Ashley Zukerman) uncover a conspiracy that led to the original catastrophe. Returning cast members include Common, Harriet Walter, Chinaza Uche, and others, while newcomers such as Laura Innes, Jessica Brown Findlay, Morven Christie, Reed Birney and Matt Craven join the ensemble. A fourth and final season has already been confirmed.
