Valve's pattern of expanding trade-up eligibility in CS2 has reshaped the economy, with the October 2025 Covert-to-knife update and May 2026 souvenir inclusion driving sharp repricing and new input demand. These changes demonstrate Valve's willingness to alter core mechanics without prior signals, often triggering rapid market adjustments similar to roster shifts or rule tweaks in major tournaments. No confirmed plans or leaks point to sticker trade-ups as of early October 2026, though ongoing Major sticker shops and community discussion around older collections keep the possibility alive. Any implementation would likely favor high-supply items and pressure legacy sticker values, with the next major client update or event serving as the primary catalyst for sentiment shifts.
