Apple TV’s teaser for season three of Silo confirms we’ll be learning more about the past in order to understand the present. “Before we can know why we’re here. Before we can know why everything is as it is. Before we can know how it all will end. We need to understand how it all began,” says Juliette (Rebecca Ferguson) in a voice-over.
Also returning for season three are Common, Harriet Walter, Chinaza Uche, Avi Nash, Alexandria Riley, Shane McRae, Remmie Milner, Rick Gomez, Billy Postlethwaite, Clare Perkins, and Steve Zahn. Ashley Zukerman and Jessica Henwick debuted in the season two finale and are back for season three.
Newcomers include Laura Innes, Jessica Brown Findlay, Morven Christie, Reed Birney, and Matt Craven. Colin Hanks appears in a recurring role.
Apple TV’s set a July 3, 2026 premiere for the 10-episode season, with new episodes streaming on Fridays.
The official synopsis reads: “Season three of Silo continues the saga of a dystopian society of 10,000 people living underground under mysterious circumstances while revealing an origin story set centuries earlier. In the present, Juliette Nichols (Ferguson) survives her forced ‘cleaning’ but returns with memory loss as the silo recovers from rebellion and faces a dangerous new threat.
Meanwhile, in the ‘Before Times,’ journalist Helen Drew (Jessica Henwick) and Congressman Daniel Keene (Zukerman) uncover a conspiracy that pulls them into a chain of events with catastrophic, irreversible consequences.”

Rebecca Ferguson, Michael Dinner, Nina Jack, Joanna Thapa, Ferguson, Morten Tyldum, Howey, Amber Templemore, Fred Golan, Rémi Aubuchon, and AMC Studios also executive produce.
