Market capitalization is the total value of all tokens currently in circulation, while fully diluted valuation (FDV) is the hypothetical total value if every token that will ever exist were circulating today. The gap between these two numbers is one of the most important — and most overlooked — signals in crypto analysis.
Imagine two projects, each with a token priced at exactly one dollar. Project A has 10 million tokens in circulation and no more will ever be created. Project B also has 10 million tokens circulating, but its schedule calls for 990 million more to be released over the next five years. Same price, same current market cap — but wildly different stories. Understanding that difference is what this guide is about.
What market cap actually measures
Market cap is calculated by multiplying the current token price by the number of tokens currently in circulation.
Market Cap = Current Price x Circulating Supply
“Circulating supply” means tokens that are freely tradeable right now — held by the public, on exchanges, or in active wallets. It excludes tokens that are locked, vested, or not yet minted.
Market cap is useful because it lets you compare projects by size rather than price alone. A token priced at $0.001 is not necessarily “cheap” if there are a trillion of them in circulation. Conversely, a token priced at $50,000 is not necessarily expensive if only a handful exist. Market cap cuts through the noise of raw price.
This is the same concept used in traditional finance for stocks, where you multiply share price by shares outstanding. It is a reasonable snapshot of the market’s current view of a project’s worth.
What fully diluted valuation measures
FDV takes the calculation one step further:
FDV = Current Price x Maximum Possible Supply
The maximum possible supply — sometimes called “max supply” or “total supply” depending on the project — includes every token that could ever exist: tokens already circulating, plus all tokens that are locked in vesting contracts, reserved for a team or treasury, earmarked for future staking rewards, or simply not yet minted.
FDV asks a pointed question: if all those future tokens were liquid and trading right now, at today’s price, what would the entire project be worth?
That question matters because those tokens will, in many cases, eventually hit the market. When they do, they expand the circulating supply — and unless demand grows proportionally, the price tends to fall.
Why the gap between them is a warning sign
A large gap between market cap and FDV signals that significant supply inflation lies ahead. Consider this comparison:
| Metric | Project A | Project B |
|---|---|---|
| Token price | $1.00 | $1.00 |
| Circulating supply | 10 million | 10 million |
| Market cap | $10 million | $10 million |
| Max supply | 10 million | 1 billion |
| FDV | $10 million | $1 billion |
| FDV / Market Cap ratio | 1x | 100x |
Project B’s FDV is 100 times its market cap. This means 99% of its tokens are not yet circulating. Holders of Project B are, in effect, betting that demand will grow fast enough to absorb nearly a billion new tokens without crushing the price. That is a significant assumption to make.
This dynamic is sometimes called token dilution, and it works the same way stock dilution works for companies that issue lots of new shares. The existing holders own a smaller slice of the total pie with each new issuance.
Where the missing tokens are
Understanding what drives the gap requires knowing the common sources of non-circulating supply. These are worth examining when you research any project — you can often find them in a project’s documentation or tokenomics page.
Team and investor allocations
Early backers and founding teams typically receive tokens at a steep discount, locked under a vesting schedule — a timeline that releases their tokens gradually, often over one to four years. These locked tokens are not in the circulating supply today but will be. See vesting and token unlocks for a deeper look at how these schedules work in practice.
Treasury and ecosystem funds
Many projects reserve a large portion of supply in a treasury or foundation wallet, intended to fund future development, grants, or partnerships. These tokens may be released slowly or all at once depending on governance decisions.
Staking and emissions rewards
Some blockchains continuously mint new tokens to pay validators or stakers. These tokens gradually expand circulating supply over time, which is a form of ongoing inflation. You can read more about how this works in inflation and emissions.
Not-yet-minted tokens
Some protocols have a defined maximum supply that has not yet been fully minted. Bitcoin, for example, has a max supply of 21 million coins, but a meaningful number have yet to be mined and will trickle into circulation through block rewards over many decades. In this case the FDV gap is real but the release pace is predictable and slow.
How to use these numbers together
Neither market cap nor FDV is the “right” number — they answer different questions.
Market cap tells you what the market values today, at current liquidity. It is the more comparable figure when sizing one project against another in the present.
FDV tells you what the market is implying about the project’s future if price holds steady. A very high FDV relative to market cap is not automatically disqualifying, but it should prompt questions: When do the locked tokens unlock? Who holds them, and what incentive do they have to sell? Does the project’s growth trajectory justify that implied future valuation?
A healthy rule of thumb: be more cautious when the FDV/market cap ratio is very high (10x or more) and token unlocks are near-term rather than years away. For background on what-is-tokenomics and crypto supply explained, those pages offer a fuller picture of how supply design shapes long-term value.
It also helps to look at the vesting cliff dates — specific moments when large tranches of locked tokens become liquid all at once. These events can create strong selling pressure even when a project is fundamentally healthy.
Key takeaways
- Market cap equals price times circulating supply — it reflects the current, tradeable value of a project.
- Fully diluted valuation equals price times maximum possible supply — it shows the implied value if all tokens were in circulation at today’s price.
- A large gap between market cap and FDV means significant new supply is coming, which can put downward pressure on price unless demand grows to match.
- Common sources of non-circulating supply include team vesting schedules, treasury reserves, ecosystem funds, and unminted tokens.
- Neither number alone is sufficient — use both together, and pay attention to when and how locked tokens are scheduled to unlock.
- FDV is not a reason to avoid a project outright, but a high FDV/market cap ratio demands careful scrutiny of the unlock schedule and growth assumptions.
