Top 10 s&box skins by market cap

The biggest items in the s&box economy by total market value. Ranked by circulating supply times the current lowest ask. Live data from the Steam Community Market.

·Auto-refreshed per request

Market cap is the cleanest single number for ranking s&box skins by economic weight: circulating supply times current lowest ask. The theoretical value of every unit in circulation at today's price, and the metric traders and collectors use to benchmark any skin's real footprint in the wider economy.

It is not exit liquidity, you could not sell the whole supply at the floor without crashing the market. But it surfaces which skins actually dominate versus which are noise. A limited skin with 500 units at $80 each has a completely different profile than a permanent skin with 50,000 units at $1.50.

The ranking below is the current top ten, recomputed from live Steam Community Market data on every visit. Thin rows update as prices move, supply figures come from the s&box store metrics, and items without a supply estimate are excluded.

Methodology

How we calculate this

Market cap for each skin is supply × lowest ask. Supply is the cumulative units sold from the sbox.game store, net of refunds, pulled from each skin's daily sales chart. Lowest ask is the cheapest active listing on the Steam Community Market. Every s&box skin originates from the store, so almost every item has a supply figure, a small number of edge cases where our store data is incomplete get excluded to keep the ranking honest.

Rankings recompute on every page load. Historical market cap charts for the entire economy live on the market pulse page.

Caveats

What this number does not tell you

Not exit liquidity
You could not sell the full supply at the lowest ask. The next ten listings sit higher. Treat market cap as a headline, not a portfolio value.
Supply can grow
If an item is still being sold in the store, supply climbs every day. A growing supply drags market cap even when demand is steady.
Refunds are netted out
Supply subtracts refunded units using each skin's daily refund series from the store. What stays in circulation is what we count.
Store price is not market price
A skin at $3 in the store can sit at $9 on the market. Market cap uses market price, the price at which the next unit would actually change hands.
FAQ

Common questions

What is market cap for a skin?
Market cap is the circulating supply of a skin multiplied by its current lowest ask on the Steam Community Market. It represents the total theoretical value of every unit in circulation at today's price. A single rare skin priced at $500 with 100 units in circulation has a $50,000 market cap.
Where does the supply number come from?
Supply is the cumulative units sold from the sbox.game store, net of refunds, taken from each skin's own daily sales chart on sbox.game/metrics/skins. Every s&box skin originates from the store, so in practice almost every item has a figure. A small number of edge-case items where our store data is incomplete get excluded from this ranking to keep the numbers honest.
Why does market cap change between visits?
Both inputs move. Supply grows when a skin is still on sale in the store, and the lowest ask changes constantly as listings are added, bought, or canceled. This page reads live values from our database on every request.
Is market cap the same as liquidity?
No. Market cap is a theoretical number. You could not actually sell every unit at the current price, a sale of that size would crash the market. Liquidity, shown on each item page, measures how much can actually trade without moving the price.
How often is this page updated?
Lowest-ask prices refresh every 15 minutes from the Steam Community Market. Supply refreshes every 6 hours from the s&box store metrics. The ranking order is recomputed on every page load.
