Market Cap vs FDV: Why the Difference Matters

Market cap and fully diluted valuation (FDV) are two different ways to value a cryptocurrency: market cap multiplies the current price by circulating supply (tokens actually available in the market today), while FDV multiplies the current price by maximum supply (every token that will ever exist), and the gap between the two reveals how much future dilution a token still carries.

Both figures are useful, but they answer different questions. Market cap tells you the current, tradable size of an asset. FDV tells you what that valuation implies once every token is unlocked and in circulation. Relying on only one without the other gives an incomplete picture.

Defining each metric precisely

Market cap = current price × circulating supply. This is the standard figure quoted on most price-tracking sites and reflects only tokens that are actually liquid and available to trade right now, distinct from the total or locked supply covered in /blog/circulating-vs-total-vs-max-supply.

FDV = current price × maximum supply. This figure includes tokens still locked in vesting contracts, unminted future issuance (where a max supply is defined), and any reserved treasury allocations not yet released, explained in more depth in our dedicated /blog/fully-diluted-valuation-explained guide.

A worked example

Consider a hypothetical token launching with the following structure:

Metric	Value
Current price	$0.50
Circulating supply	200 million
Max supply	5 billion
Market cap	$100 million
FDV	$2.5 billion

At first glance, a $100 million market cap might appear to be a small, early-stage opportunity. But the $2.5 billion FDV shows that, if the market maintained this same per-token price as the remaining 4.8 billion tokens unlock, the project would eventually be valued 25 times larger than its current headline market cap suggests. That's a meaningful amount of future dilution priced against a token that, on the surface, looks inexpensive.

Why the ratio between the two matters more than either number alone

The FDV-to-market-cap ratio is often more informative than either figure in isolation. A ratio close to 1 means most of the supply is already circulating, so there's limited future dilution ahead. A ratio of 10, 20, or higher means the vast majority of the eventual supply is still locked, and each future unlock event, tracked using methods described in /blog/how-to-track-upcoming-token-unlocks, represents a meaningful addition to the market's available supply.

FDV / Market cap ratio	Interpretation
~1x	Most supply already circulating; low future dilution
2x – 5x	Moderate remaining unlock schedule
10x or higher	Majority of supply still locked; high dilution risk

Why this matters more for new tokens

Newly launched tokens are especially prone to large FDV-to-market-cap gaps, since it's common for only a small fraction of total supply to be circulating at launch, with the rest allocated to team, investors, and ecosystem funds under long vesting schedules, discussed in /blog/token-unlocks-explained. Established, mature tokens that have already fully unlocked their supply — where market cap and FDV converge — carry much less of this particular risk, though they naturally carry other risks of their own.

Practical takeaways for research

When comparing two tokens, don't rely on market cap alone to judge relative size or "cheapness." Check FDV alongside it, understand what portion of supply is still locked, and factor in the vesting timeline before assuming a low market cap represents genuine value. This kind of comparison fits into the broader /blog/what-is-tokenomics-crypto framework of evaluating supply, distribution, and utility together, rather than any single number in isolation.

Where to find both figures

Reputable data aggregators generally display market cap and FDV side by side for any listed token, along with the circulating and max supply figures used to calculate them, as covered in /blog/circulating-vs-total-vs-max-supply. It's worth checking a project's own published tokenomics documentation as well, rather than relying solely on a third-party aggregator, since discrepancies between a project's stated max supply and what's reflected on a given data platform can occasionally arise, particularly for newer or less widely tracked tokens.

Bottom line

Market cap shows a token's current, liquid valuation, while FDV shows what that valuation implies once fully unlocked — and the gap between them is a critical, often overlooked piece of due diligence. Always check both figures together, especially for newer tokens with large unvested allocations, before judging whether a project is genuinely undervalued or simply appears that way because of its supply structure.
