Apple TV’s Silo Season 3 Trailer Reveals a Bigger World and New Secrets

Jun 23

Apple TV has released the trailer for season three of Silo, offering a sharper look at the mystery expanding beneath—and beyond—the underground refuge.

Rebecca Ferguson, Avi Nash, Rick Gomez, Common and Harriet Walter in "Silo," premiering July 3, 2026 on Apple TV.

The season premieres July 3, with weekly episodes through September 4. Rebecca Ferguson returns as Juliette Nichols, whose search for answers has exposed the lies holding the silo together.

Following season two’s rebellion, Juliette has survived her forced “cleaning” but returns with memory loss. The trailer positions that damage at the center of an unstable community, as fallout from the uprising strains the silo’s fragile order. And with a new threat looming, Juliette’s missing memories may hold answers residents need most.

Silo Heads Back to the Beginning

Season three also reaches into the “Before Times,” shifting centuries earlier to investigate the events that created the world entombed underground. Jessica Henwick joins as journalist Helen Drew, while Ashley Zukerman plays Congressman Daniel Keene. Their investigation into a widening conspiracy connects the show’s present-day unrest with the catastrophe that reshaped humanity.

Based on Hugh Howey’s bestselling Silo trilogy, the Apple TV drama is created by Graham Yost, who serves as showrunner and executive producer. The returning ensemble includes Common, Harriet Walter, Chinaza Uche, Avi Nash, Alexandria Riley, Shane McRae, Remmie Milner, Rick Gomez, Billy Postlethwaite, and Clare Perkins. New cast members include Laura Innes, Jessica Brown Findlay, Morven Christie, Reed Birney, and Matt Craven, while Colin Hanks will recur and Steve Zahn returns.

Apple has also renewed Silo for a fourth and final season, which means there’s still plenty more chaos to come. Seasons one and two are now streaming on Apple TV.
