The next season of Slow Horses is expected to arrive sometime in 2026, most likely in the fall or early winter, but there is no officially confirmed premiere date yet as of January 2026.

Whatā€™s known right now

  • Season 6 has already finished filming, so a 2026 release is strongly expected rather than a later year.
  • Apple has been releasing roughly one season per year, which lines up with predictions for a fall/winter 2026 launch.
  • Recent coverage and fan discussions describe the date as speculative, with outlets and forums repeatedly stressing that Apple TV+ has not announced a specific day or month yet.

Best current estimate

  • Several entertainment sites and news pieces suggest a fall 2026 window (Septemberā€“November) as the most likely timeframe, based on the pattern of previous seasons and Appleā€™s oneā€‘seasonā€‘perā€‘year approach.
  • Some fan speculation leans toward late summer or early fall 2026, but this is not official and should be treated as informed guesswork rather than a firm schedule.

Quick ā€œforum-styleā€ take

ā€œSlow Horses fans are basically in waiting mode: Season 6 is shot, 2026 is almost a lock, but Appleā€™s keeping the exact date under wraps. Expect the usual: another gritty, funny spy run sometime around fall 2026ā€”unless Apple surprises everyone with an earlier drop.ā€
