Apple TV has become a go-to service for sci-fi fans, with shows like Severance and Pluribus proving big hits. Another popular series is dystopian thriller Silo, which has a season 3 coming later this year. Here’s everything we know so far about Silo season 3.
Season 3 expands the story outside the silos
Silo season 2 ended on a bit of a cliffhanger.
While the series to this point has been set almost exclusively inside underground silos, the season 2 finale shook things up.
Creator and showrunner Graham Yost confirmed that’s a sign of things to come:
“Yes, we will be outdoors, and we will be in the world, and there will be sunshine,” Yost said, speaking to the parts of Season 3 that will be brighter.
As anyone who has read the full series of Silo books knows, it’s a safe bet that there will be lots of non-silo scenes coming in season 3.
New lead actors join the cast
Related to that finale cliffhanger, Silo season 3 will add two new lead actors to the cast.
As first seen in season 2’s closing scene, Ashley Zukerman and Jessica Henwick join the current ensemble in a big way next season.
Juliette and the rest of the Silo characters you know and love will still be around, but with some new faces in the mix too.
Four seasons coming in total, with full Apple TV greenlight
Silo is based on a trilogy of books by Hugh Howey, so the show’s creators have a pre-set template to follow.
Book 1’s story was split over both seasons 1 and 2 of the show. It’s expected that books 2 and 3 won’t be followed strictly chronologically in the TV adaptation. Instead, the events of both books will be intertwined during the upcoming seasons 3 and 4.
Apple TV has already greenlit all four seasons of Silo. And once season 4 airs, the series will be complete.
“It has been a richly rewarding experience to adapt Hugh’s epic novels with our partners at Apple, and we are thrilled to have the opportunity to bring this complete story to the screen over the course of four seasons,” said showrunner and executive producer Graham Yost. “With the final two chapters of ‘Silo,’ we can’t wait to give fans of the show an incredibly satisfying conclusion to the many mysteries and unanswered questions contained within the walls of these silos.”
When to expect Silo season 3 on Apple TV
Apple TV announced back in May 2025 that Silo season 3 had officially wrapped shooting.
Post-production work shouldn’t take more than a full year, which means we’re expecting to see Silo season 3 premiere around summer or fall 2026.
In theory it could arrive sooner, but Silo’s absence from Apple TV’s big media event last week makes that unlikely. However, as mentioned in a recent interview with star Rebecca Ferguson, 2026 is definitely the plan.
You can watch the first two seasons of Silo here on Apple TV.
Apple TV is available for $12.99 per month, or you can get it discounted through the Apple One bundle.
