When is 'Silo' Season 4 coming out?

Silo Season 3 delivered answers in a major way, showing viewers the nuclear explosion that sent people underground and revealing what's inside the sinister Silo 1. Of course, in true Silo fashion, its Season 3 finale also left us with some big questions. Most importantly: How in the world is Juliette Nichols (Rebecca Ferguson) going to bring down the powerful forces within Silo 1?

Luckily, there's one question we can get answers to right away, and that's the classic post-finale question of, "when can we see more?" That's because Apple TV has already unveiled the exact release date of Silo Season 4.

What is Silo Season 4's release date?

Silo's fourth and final season will premiere on July 9, 2027. That means you have a little under a year to hammer out all your theories for Juliette's upcoming confrontation with Silo 1's Daniel Keene (Ashley Zukerman), now memory-wiped and referred to as Troy.

Does Silo Season 4 have a trailer?

Apple TV has released a teaser for Season 4, giving us ample material for speculation and analysis in the months to come. Fair warning, though. It's incredibly spoiler-y, so watch and read on with caution.

The first look teases flashbacks to Helen Drew's (Jessica Henwick) first moments in Silo 18, right after the nuclear bomb went off. It also shows that Sheriff Paul Billings (Chinaza Uche) tells the entirety of Silo 18 the truth about the other silos, including how Silo 1 controls them and has led them to believe that the air outside the silos is poisonous.

Most intriguingly, the teaser gives us a flash of trillionaire Per Stensen (Colin Hanks), who's bee missing since the end of episode 9. Of course, the biggest reveal of all is that Juliette and Daniel/Troy will finally meet face to face.

How will all this play out? We'll have to wait until summer 2027 to find out. Start the countdown, and please theorize responsibly.

Silo Season 3 is now streaming on Apple TV. Silo Season 4 premieres July 9, 2027.
