About CS2 Skin Predictor
CS2 Skin Predictor is a free, independent tool that applies machine learning to the CS2 skin market. Every day, our models analyse price history, trading volume, and market momentum for over 8,000 Counter-Strike 2 weapon skins and produce forward-looking price forecasts across four time horizons: 7, 30, 60, and 90 days.
The site was built for CS2 players and collectors who want a data-driven edge when deciding whether to buy, sell, or hold a skin. We don't offer financial advice — skin prices are volatile and no model is perfect — but we do give you a rigorous, consistent framework to inform your decisions rather than relying on gut feeling or social media hype.
All predictions are updated daily and are free to use. There is no login, no paywall, and no subscription required.
How it works
Data collection
Our collector runs every night, pulling daily price and volume data from the Steam Community Market for every active CS2 weapon skin. This gives us a rich time series going back several years for the most established skins. We track the median sale price and daily trading volume, which together give a clear picture of both where a skin is priced and how liquid the market for it actually is.
Feature engineering
Raw prices alone are not particularly predictive. Before training, we transform the price history into a set of features that capture the patterns a model can learn from. These include:
- Log returns over multiple windows (7, 14, 30, 60, 90 days)
- Rolling price volatility — how much the price has been swinging
- Volume trends — whether trading activity is rising or falling
- Price momentum signals — is the skin accelerating or decelerating in price?
- Relative price position — where is the current price relative to its historical range?
In total we generate 24 features per skin per day. These are the inputs the model uses to make its prediction.
The model
We use LightGBM, a gradient boosting framework that is well suited to structured tabular data like market time series. Rather than predicting a single price, the model uses quantile regression — it outputs a low estimate (25th percentile), a mid estimate (50th percentile), and a high estimate (75th percentile) for the price at each horizon. This gives you a realistic range rather than a false sense of precision.
We train a separate model for each time horizon (7, 30, 60, 90 days), since the signals that predict short-term moves are different from those that predict longer-term trends. Models are retrained periodically as new market data accumulates.
Backtesting
Every model is backtested against real historical data — we run it against past price history and check how often the actual price ended up inside our predicted range, and how often we correctly predicted the direction of movement (up or down). These results are published openly on the homepage accuracy widget and are updated each time the model runs. We don't cherry-pick results.
Across our best horizon (90 days), our model correctly predicted price direction approximately 73% of the time in backtesting — compared to 50% if you simply guessed. Range accuracy (the actual price landing inside our low-to-high band) sits around 54%. These numbers will change as the model is retrained with fresh data.
Understanding the signals
Each skin is given a signal based on the predicted price change over the chosen horizon:
Predicted to rise by more than 5%
The model expects the skin's price to increase meaningfully over the horizon period. This does not guarantee a rise — it means the historical patterns present in this skin's data are similar to patterns that preceded price increases in training data.
Predicted to fall by more than 5%
The model expects the skin's price to decline meaningfully. If you currently own this skin, a Bearish signal is worth considering — though market conditions can change rapidly and the model cannot account for surprise game updates or case releases.
Predicted to stay within ±5%
The model sees limited movement expected in either direction. The skin may be a reasonable hold, but may not be the best candidate for short-term trading.
The 5% threshold is used to distinguish meaningful price moves from normal noise. A 2% move in a skin's price is often within the spread of the market and not significant enough to act on.
How to use this site
Searching for a specific skin
Use the search bar on the homepage to find any skin by name. The skin page shows its full price history, our predictions for each time horizon, and a commentary explaining what the model is seeing.
Browsing by signal
The Catalogue lets you filter all 8,000+ skins by signal (Bullish, Bearish, Neutral), weapon type, wear, and price range. This is useful if you're looking for buying opportunities across the whole market rather than checking individual skins.
Choosing a time horizon
Shorter horizons (7 days) are noisier but more actionable for active traders. Longer horizons (90 days) are more accurate in backtesting and better suited to collectors deciding whether to hold or sell. The "Most Accurate" badge on each skin page highlights which horizon has performed best for that model in backtesting.
Reading the prediction range
Each prediction shows a low, mid, and high price. Think of this as a confidence interval — the model expects the price to land somewhere in this range about 54% of the time. The mid price is the model's best single estimate.
Frequently asked questions
How often are predictions updated?
Predictions are recalculated every night after the latest market data has been collected. By the time you visit the site each morning, the forecasts reflect yesterday's closing prices.
Why does the model sometimes get it wrong?
No model can predict the future perfectly, especially in a market as sentiment-driven as CS2 skins. The model learns from historical price patterns but cannot anticipate surprise events — a major game update, a new case release, or a streamer going viral with a particular skin can all move prices in ways that have no historical precedent. Always treat predictions as one data point, not a guarantee.
Are StatTrak skins included?
Yes. StatTrak versions of skins are tracked and predicted independently from their standard counterparts, since they trade at a premium and can have different price dynamics.
Are knives and gloves included?
Not yet. The current model covers weapon skins only. Knives and gloves will be added in a future update.
Where does the price data come from?
All price and volume data comes from the Steam Community Market. We collect it directly each night. We are not affiliated with Valve or Steam — we simply use the publicly available market data.
Is this financial advice?
No. CS2 Skin Predictor is an informational tool only. Nothing on this site constitutes financial advice. Skin prices can be highly volatile. Never spend money on skins that you cannot afford to lose in value.
