Apple TV+ has renewed its popular sci-fi series Silo for both Season 3 and Season 4. Season 4 will be the show’s final season.
The series follows Rebecca Ferguson as Juliette, an engineer who discovers dark secrets in a massive underground shelter. The show adapts Hugh Howey’s dystopian novels.
Production Updates
Season 3 filming started in October 2024 and finished in June 2025. The production team decided to film Seasons 3 and 4 back-to-back to speed up the process.
Season 4 filming began right after Season 3 wrapped up in May 2025. The cast and crew are currently working on the final season.
When to Expect New Episodes
Season 3 will likely arrive in late 2025 or mid-2026. Previous seasons took 8 to 12 months to release after filming ended.
Season 4 should follow sometime after Season 3 airs, possibly in late 2026 or early 2027. Since both seasons filmed close together, fans might not wait as long between them.
What Comes Next
The story will continue exploring why humans live underground and what happened to the outside world. Season 2’s ending set up major reveals about the silo’s purpose.
Season 4 will wrap up the entire story based on Howey’s three-book series: Wool, Shift, and Dust.
The show has earned praise for its storytelling, visual design, and Ferguson’s performance. Fan interest remains strong as the series heads toward its conclusion.
Silo viewers can expect two more seasons that will complete the dystopian mystery. With filming already underway, the wait for answers is getting shorter.
