Silo Season 4 is officially happening, and yes, the cameras are about to start rolling soon. Even before Season 3 is released, the creators are already moving forward with the fourth and final season of the series.
Cinematographer Baz Irvine has confirmed the news, and fans of the show can breathe a sigh of relief knowing the story's pace isn't slowing down after Season 3. So, what's the latest behind-the-scenes update? How close are we to a Season 4? Let's break it all down right here just for you!
Filming prep for Silo Season 4 is already underway!
Although Season 3 hasn't premiered yet, the gears for Silo Season 4 are already shifting.

Cinematographer Baz Irvine spoke to ScreenRant in an interview shared:
"Three is actually just finished... [and they're] actually about to start season four."
While Irvine isn't returning for this season, his comments made it clear that the production isn't wasting time. Season 3 wrapped up in May 2025, and just weeks later, plans for the 4th season have been made with a yes.
The fact that Apple TV+ renewed Silo for Seasons 3 and 4 in one go is a big win for the show's vision. Irvine described Season 2's filming experience as long and intense, saying;
"It ended up being 15 months... a lot of that time is spent in subterranean sets, going slightly crazy due to lack of sunlight."
He further added;
"I wanted to experience some other things..."
And this is why he withdrew from the final installment. His honest insight shows how demanding the production has been but also how much attention to detail is involved.

With director Michael Dinner continuing, the next chapter of Silo Season 4 appears to benefit from consistent behind-the-scenes work, ensuring the tone is maintained for the big finale. For now, all indications suggest a smooth production with no delays expected.
Timelines hint at a 2027 release for Season 4
Since Season 3 just wrapped and hasn't been released yet, the timeline for Silo Season 4 naturally extends into the future. But if everything goes as planned and expected, fans might see the final season sometime in early or late 2027.
Michael Dinner's involvement helps maintain the show's creative consistency. While the books hint at what might come next, the show has already taken several sharp deviations from the source material.
What happens in Silo Season 4 could be unpredictable, which makes it even more exciting for fans. However, Apple TV+ has made no official statement about what comes after this season. But given the show's popularity and its vast universe, fans can hope for spinoffs or prequels once the main story concludes.
For now, Silo Season 4 is moving full speed ahead. With the production team already getting into gear and no major setbacks in sight, fans of this series have plenty of reason to be excited. The final season might still be a little while away, but it's already shaping up to be worth the wait.
