Cache has already come to CS2 Premier: Valve confirmed Cache for the Active Duty pool in Premier Season Five , with the swap happening when Premier Season Four ends on July 6, 2026.

What that means

  • Cache is joining the competitive map rotation, replacing Overpass.
  • The Season Five pool will include Dust 2, Inferno, Mirage, Nuke, Ancient, Anubis, and Cache.
  • Pro play is expected to start using the updated pool at BLAST Bounty on July 21, 2026.

Quick note

Earlier reports in April said Cache was returning to CS2 more broadly, and later coverage confirmed the Premier Active Duty timing.

Bottom line

If you mean Premier specifically, the answer is July 6, 2026 for the pool change, with Cache becoming part of the Premier rotation then.
