Valve's measured update cadence and recent Cache addition to the active duty pool in mid-2026 continue to anchor low implied probabilities for a near-term Cobblestone return. The map has remained absent from competitive and Premier rotations since its 2018 removal, with Valve prioritizing tested layouts over community calls for the castle-themed classic. Persistent datamined assets, including snowy visual layers and environmental files, signal active development, yet the 17-month gap between Train and Cache underscores Valve's preference for thorough iteration before rotation changes. Upcoming Premier seasons or major patches could accelerate testing, though roster form and meta shifts rarely influence map decisions directly. Traders note that any addition requires official Active Duty confirmation, not just workshop or casual play.

If Cobblestone is added to the Active Duty pool, it must remain there continuously for at least 48 hours for the relevant market to resolve to "Yes". Temporary additions (e.g., for testing) that are reversed within 48 hours will not count. If Cobblestone is added after the deadline, the relevant market will resolve to "No", even if the addition was announced earlier.
For the purpose of this market, "Valve" refers to Valve Corporation, the developer and publisher of the Counter-Strike series.
For the purpose of this market, the "official map pool" refers to the Active Duty map group in Counter-Strike 2 (CS2), which consists of the maps eligible for both competitive matchmaking and professional tournaments.
The primary resolution source for this market will be official information from Valve; however, a consensus of credible reporting may also be used.
