How many episodes are in Silo season 3?

Ten. The season premiered on 3 July 2026 and released one episode a week on Fridays, ending with episode 10 on 4 September. There is no split-season break; the run was continuous.

Do I need an Apple device to watch Silo?

No. The Apple TV app runs on Roku, Amazon Fire TV, Google TV, Android TV, PlayStation and Xbox consoles, and Samsung, LG, Sony, Vizio and Hisense smart TVs, as well as in a web browser. An Apple account is required, but Apple hardware is not.

How much does Apple TV cost to watch Silo?

$14.99 a month in the US, after the price increase Apple applied in August 2026. New subscribers get a seven-day free trial, and the service is also sold inside Apple One and as a bundle with Peacock.

Will there be a Silo season 5?

No. Apple confirmed when it renewed the show in December 2024 that season four would be the final season, completing the adaptation of Hugh Howey's three-book series. Nothing beyond season four has been announced.

When does Silo season 4 come out?

Apple has confirmed a summer 2027 window and nothing more specific. Filming wrapped in March 2026, since seasons three and four were shot back to back, so the date is a post-production schedule rather than an estimate.

Silo Season 3 Finale Is Out Now on Apple TV

What time did the Silo season 3 finale drop?

Apple releases new episodes at the same moment worldwide, so the finale unlocked simultaneously everywhere rather than at local midnight. In the major zones that works out to:

12:00 a.m. PT — US West Coast, Friday 4 September

3:00 a.m. ET — US East Coast, Friday 4 September

8:00 a.m. BST — United Kingdom

9:00 a.m. CEST — Western Europe

12:30 p.m. IST — India

4:00 p.m. JST — Japan

5:00 p.m. AEST — Eastern Australia

If the episode is not showing yet, the usual cause is a cached library rather than a delayed rollout. Force-quitting the Apple TV app and reopening it, or pulling down to refresh on mobile, normally surfaces it within seconds.

Where can you watch it?

Silo is an Apple original, so the only legitimate home for it is the Apple TV app. That app is not locked to Apple hardware: it ships on iPhone, iPad, Mac and the Apple TV box, and it is also available on Roku, Amazon Fire TV, Google TV, Android TV, PlayStation and Xbox consoles, and the smart TV platforms from Samsung, LG, Sony, Vizio and Hisense. There is a browser version too, which is the fallback worth remembering if your TV app is misbehaving.

A subscription runs $14.99 a month in the US, following the increase Apple applied last month — we covered what changed with Apple TV and Apple One pricing at the time. New accounts get a seven-day free trial, which is enough to watch the whole of season 3 in one sitting if you have not subscribed before. Apple also sells the service inside a bundle with Peacock, which is worth pricing up if you already pay for both separately.

Is Silo coming back for season 4?

Yes, and it will be the last one. Apple renewed the series for seasons three and four together back in December 2024, and stated at the time that the fourth season would complete the adaptation of Hugh Howey's three-book series. In July Apple confirmed a summer 2027 window for that final run — no exact date has been announced, and nothing narrower than the season has been made official.

Production is already well ahead. Seasons three and four were filmed back to back, with work on the final season wrapping in March 2026. That is a long runway for an effects-heavy show, and it is the reason a 2027 date is a schedule rather than an aspiration. Apple has also attached a Season 4 sneak peek to the show's bonus content, so there is something to watch immediately after the credits roll on episode 10.

What else is worth queueing up on Apple TV?

The gap after a finale is the point at which a lot of people cancel, so it is worth knowing what is next. Slow Horses returns on 16 September with weekly episodes running into late October, which covers most of the rest of the quarter. If you are watching on Apple's own box rather than a TV app, there is also a new Apple TV 4K and Siri Remote referenced in Apple's own code, which is relevant if you were about to buy the current model.

A note on spoilers

Because Apple drops episodes globally at one moment, viewers in Asia and Australia finish hours before the US wakes up. Social feeds and forum threads carry finale detail long before most American subscribers press play, so mute the show's name for the day if you cannot watch straight away.
