Cases · CS2 Index

The CSMarketCap Cases index tracks the combined cheapest-cross-market value of every Cases item in CS2. It updates every six hours and aggregates prices from Buff163, CSFloat, Steam, DMarket, Skinport, Waxpeer, and Youpin. The chart on this page shows how the Cases category has traded daily over the past year, while the table below ranks every Cases skin we track by 30-day price movement weighted by liquidity. Use it to spot which Cases skins are moving and gauge the overall direction of the Cases market.

For every Cases item we take the lowest available price across the seven trusted CS2 marketplaces we monitor, filter out outlier listings priced more than 3× above the cheapest market, then sum that one-of-each price across all Cases skins. The result is a single USD value that moves with the entire Cases segment of the CS2 economy. The 30-day median percent on the page is calculated the same way as the breadth: we order every Cases item by its individual 30-day change and pick the middle value, so outliers don't skew the headline number.

Category-wide moves typically reflect a few drivers: a new Counter-Strike 2 operation injecting supply into the market, an esports event boosting sticker or souvenir demand, Steam Market policy changes, broader skin-economy sentiment, or large-volume trades from key holders. The breadth indicators on this page tell you whether the move is broad-based — most Cases items moving together — or concentrated in a few popular skins. The biggest-gainer and biggest-loser cards above the table highlight which specific Cases items drove the headline change.

The Cases index refreshes every six hours, in sync with the price-statistics cron that powers all of CSMarketCap. Item-level prices in the table come from continuous polling — typically every few minutes per marketplace. The hero chart shows daily aggregates going back over a year, sourced from the same ClickHouse table that powers every per-item price chart on the site, so the Cases curve is consistent by construction with the individual item charts inside the category.

Every Cases item in CS2 that has price data on at least one of our seven indexed marketplaces (Buff163, CSFloat, Steam, DMarket, Skinport, Waxpeer, Youpin). The number on this page header reflects how many Cases items currently have valid 30-day price statistics — that's the universe the index is calculated against. Items that have never traded, Steam-only items with no third-party data, and a handful of special variants (sticker slabs, souvenir charms) are excluded so the index reflects real liquid Cases pricing.

CSMarketCap is a price-tracking tool, not investment advice. That said, the Cases index gives you data to form your own view: 30-day trend, breadth (how many items are participating in the move), volume signals from sales-per-week, and which specific Cases skins are the biggest movers. Skins are volatile, illiquid for high-tier items, and depend on Valve's evolving policies. Use the index to time entries, diversify across items, and avoid concentration in a single high-value skin.
