Season 6 of Slow Horses does not have an official, exact release date yet, but multiple industry outlets and fan discussions expect it to arrive sometime in 2026, most likely in the fall (with some speculation it could drop earlier, around late spring or summer).

Quick Scoop

  • There is no confirmed day-and-month premiere date for Slow Horses season 6 yet.
  • Apple TV+ has officially renewed the show through at least season 6 (and even season 7), and season 6 has already been filmed.
  • Most reputable reports place the expected window in 2026, often described as “fall or winter 2026,” though some informed fan speculation suggests it could arrive earlier in mid‑2026 because filming wrapped in 2025 and the show has a history of relatively short gaps.

What the outlets are saying

  • Entertainment and TV news sites note that:
    • There is no official premiere date announced.
* Season 6 is already shot, which usually points to a 2026 release rather than later.

* Several previews and explainers explicitly phrase the window as “fall or winter 2026” while being clear that this is expectation, not a locked date.
  • One detailed breakdown of past premiere dates highlights the pattern:
    • Season 1: April 2022
    • Season 2: December 2022
    • Season 3: November–December 2023
    • Season 4: September–October 2024
    • Season 5: September–October 2025
      From that, many commentators infer that season 6 will follow roughly an annual cycle.

Fan and forum chatter

  • Fans on TV and Apple TV+ subreddits point out that:
    • Seasons tend to be shot in pairs, then released roughly a year apart, which would support a 2026 drop for season 6.
* Some users argue season 6 might come **earlier than “fall 2026”** , suggesting May–June 2026 based on how quickly earlier filmed seasons moved to air.

In short: expect Slow Horses season 6 in 2026, probably in the back half of the year, but be prepared for the possibility of an earlier‑than‑fall surprise if Apple sticks to its tighter gaps between paired seasons.
