Market Cap and FDV: What Changes as Token Supply Grows
Market cap uses circulating tokens, while FDV applies today’s price to a broader supply. Track unlocks and price separately to see what each figure can tell you.

Market cap multiplies a token’s current price by its circulating supply; fully diluted valuation (FDV) multiplies that price by a broader supply figure, often the maximum supply. To compare them as supply changes, check which tokens count in each figure, then separate the effect of new circulating tokens from any change in price.
The calculation has two moving parts. A market data service takes a token’s quoted price and multiplies it by the number of tokens it classifies as circulating. For FDV, it uses the same price but substitutes the maximum supply when one is defined. If there is no known maximum, services may use another supply figure, so check the definition before comparing sites. For the chart side of watching several tokens together, this Poocoin multi-chart walkthrough covers how to keep pairs visible at once; supply figures still need their own check.
What does market cap measure?
Market cap estimates the value of tokens currently in circulation at the latest quoted price. If a token trades at $2 and 10 million tokens count as circulating, its market cap is $20 million. The price comes from trading; the circulating count comes from a supply definition maintained by the project or data provider.
That count can include tokens held by users and exclude tokens that remain locked or are not yet released. Providers may differ in how they classify restricted, vested, or otherwise unavailable tokens. So market cap is an estimate based on a stated supply method, not a count that is automatically identical across every dashboard.
When tokens unlock and enter circulation, the market cap calculation can rise even if the price stays unchanged: the multiplying supply number has increased. But an unlock does not mechanically set the token’s price. If the price falls, market cap can decline despite the larger circulating count. Read the two inputs separately.
What does FDV add to the comparison?
FDV shows what the valuation would be if the chosen broader supply were priced at today’s market price. It is a calculation, not a forecast of what the token will be worth when all tokens are released. If the maximum supply is fixed at 100 million, a $2 price produces a $200 million FDV whether 10 million or 50 million tokens are circulating.
The gap between FDV and market cap points to supply that is not currently counted as circulating under that provider’s method. A large gap means more tokens could enter circulation over time, but the ratio alone says neither when they will arrive nor whether the price will hold. Check the release schedule and the supply definition alongside the headline figures.
Think of market cap as pricing the seats currently occupied and FDV as pricing every seat at today’s ticket price. The analogy stops there: tokens can unlock on a schedule, and their trading price can move before or after release.
How should you compare them over time?
Compare the same token across dates, using the same source and definitions where possible. A simple record of price, circulating supply, market cap, and FDV helps show which input changed. If you compare projects, make sure their supply figures are defined on a similar basis.
- If price rises while circulating supply is steady, market cap rises with it.
- If supply enters circulation while price is steady, market cap rises because the counted supply grew.
- If price falls as supply grows, market cap can rise, fall, or stay near its old level depending on which change is larger.
- If the maximum supply and price are unchanged, FDV stays unchanged even as tokens unlock into circulation.
For practical reading, start with market cap to see the valuation implied by the supply currently counted as circulating. Use FDV to understand how much broader the supply basis could be, then examine release timing and price changes before drawing a conclusion. Neither figure, by itself, measures demand, liquidity, or the likely effect of future token releases.
