The next series of Slow Horses does not have an officially confirmed release date yet, but season 6 is expected to arrive sometime in 2026, most likely in the second half of the year.

What’s officially known

  • Season 6 has been filmed, and reporting indicates that production wrapped in early–mid 2025.
  • Apple TV+ has not announced a precise premiere date, only that season 6 is on the way and due in 2026.
  • The show is already renewed beyond that, with at least a season 7 in development.

Likely release window

  • Trade and TV sites note that recent seasons have formed a pattern: Season 3 (late 2023), Season 4 (Sept–Oct 2024), Season 5 (Sept–Oct 2025). This points to a 2026 release for season 6, probably around autumn.
  • Some fan discussions suggest it could arrive a bit earlier (late spring or summer 2026) because filming is complete and seasons 5 and 6 were shot close together, but this remains speculation, not an official date.

Quick answer recap

  • Is there a confirmed date? No, not yet; only “sometime in 2026.”
  • Most realistic expectation right now? A 2026 premiere, with many outlets and fans expecting late 2026 unless Apple TV+ surprises viewers with an earlier slot.
