A trade-up contract in CS2 is a built-in Steam feature that consumes 10 items of the same rarity grade (Consumer, Industrial, Mil-Spec, etc.) and outputs one random item from the next rarity tier. The output item comes from the same collection as the majority of the input skins. This mechanic creates arbitrage opportunities: if you can buy the 10 input skins for less than the expected value of the output, you turn a profit over time.
Float values also matter—the output float is the average of the input floats, so using low-float inputs can yield a Factory New or Minimal Wear result that sells for a premium. Collections like The 2021 Dust 2 Collection and The 2021 Mirage Collection are popular because their high-tier skins (e.g., M4A1-S | Printstream, Desert Eagle | Printstream) command high prices, while the lower-tier filler skins are cheap.
