Valve’s October 2025 and May 2026 updates expanded trade-up contracts to include Covert skins for knives/gloves and Souvenir items for standard upgrades, sharply repricing large segments of the CS2 skin economy without touching stickers. No patch notes, official communications, or credible leaks since then indicate sticker trade-ups—defined as combining lower-tier stickers for higher-tier results—are under development. Valve’s deliberate release cadence and silence on the topic have kept community speculation contained, with the Polymarket contract reflecting an 8% implied probability of implementation by the October 31, 2026 deadline. Any future change would likely follow the same pattern of sudden, low-profile rollout seen in prior contract expansions.
