Every CS2 case ranked by real expected value. We price each possible drop at the cheapest live listing across 26 marketplaces, weight it by the true unbox odds, and compare the result against the case plus key cost. The honest takeaway: almost every case loses money on average. This shows which lose the least, and where the big upside actually sits.
ROI is the average return per open (case + key cost). A negative ROI is the long-run house edge, not a guaranteed loss on a single open. Want to feel it? Try the case opening simulator.
For almost every case the expected value of the drops is lower than the case-plus-key cost, so opening at scale loses money on average. The exception is a handful of older or discontinued cases whose rare special items have appreciated; our ranking flags any case where live drop value beats the open cost.
Each open follows the published rarity odds: Mil-Spec (blue) 79.92%, Restricted (purple) 15.98%, Classified (pink) 3.2%, Covert (red) 0.64%, and a rare special item (knife or gloves) at 0.26%. Each item also has roughly a 10% chance to roll StatTrak.
The rare special item slot — knives in weapon cases, gloves in glove cases — drops at about 0.26%, or roughly 1 in 400 openings. Which exact knife, finish, pattern, and float you then get is randomized again, so high-value blue gems or low-float Doppler phases are far rarer still.
No case reliably profits, but the strongest value is usually a discontinued case with high-priced Covert skins and rare knives relative to its low buy price. Our list ranks cases by current ROI so you can see which holds the best value at today's prices instead of guessing.
Cases trade on the Steam Community Market and most third-party CS2 marketplaces, with prices that drift over time and differ between sites. SkinWise compares the same case across 24+ markets so you can buy at the lowest current price and check fees before you commit.
