What is fully diluted valuation (FDV)?

Fully diluted valuation, or FDV, asks a blunt hypothetical: what would a coin be worth if every token that will ever exist were already trading, right now, at today’s price? Ordinary market cap only counts the tokens actually circulating. FDV counts the lot — the maximum (or total) supply — which makes it a projection of size under full dilution rather than a picture of the market as it stands today.

What follows is a walk through how FDV is calculated, how it differs from market cap, and the places it quietly misleads people. It’s educational, and it describes a metric. It isn’t a valuation judgement or a nudge to act.

What fully diluted valuation measures

The formula copies market cap and swaps one input:

FDV = current price × maximum supply

Maximum supply means every token the protocol will ever create — the ones still locked in vesting, sitting in reserve, or not yet minted. Price all of them at the current market price and you get an answer to a made-up question: if the whole supply were trading today and the price didn’t budge, how big would this asset be? Because it counts tokens that aren’t tradable yet, FDV comes out larger than market cap almost every time. Sometimes by a hair. Sometimes by ten or twenty times.

An illustrative example

These figures are invented to show the arithmetic. They’re not market data and don’t describe any real asset.

Only 10% of the supply is circulating here, so FDV lands at ten times the market cap. The other 900 million tokens are scheduled to reach the market over time. And that gap between the two numbers? It’s the entire reason to look at FDV — it makes the pending supply visible instead of hidden.

Why the gap between FDV and market cap matters

The distance between market cap and fully diluted valuation is a rough gauge of how much future supply is still waiting in the wings. A wide gap means a big chunk of tokens is locked and will arrive later — through vesting schedules, staking emissions, ongoing minting. As those tokens reach the market, circulating supply climbs and market cap drifts toward FDV. But only if the price holds. It doesn’t have to.

So read the two together, always. Market cap reflects what’s priced and tradable today; FDV reflects the size implied by the full supply. We cover the inputs on their own in what is market cap in crypto and what is circulating supply. Neither is the “true” value — they just answer different questions.

Reading the FDV-to-market-cap ratio

One practical trick is to treat FDV as a ratio against circulating market cap. Divide FDV by market cap — the same thing as comparing maximum supply to circulating supply — and you get a quick read on how much of the eventual supply is already out there:

• A ratio close to 1 means market cap and FDV are nearly the same, so almost every token is already circulating and there’s little dilution left to come.
• A large ratio (FDV several times market cap) means only a sliver of supply is trading and plenty is still locked, so a lot of dilution is scheduled ahead.

Neither reading is good or bad on its own. They just describe where a token sits in its distribution. A high ratio isn’t an accusation and a low one isn’t a gold star — both are plain facts about supply that put the headline number in context.

How the gap closes: an illustrative timeline

Again, invented figures, shown to illustrate the mechanism rather than any real data. Picture a token where 10% of supply circulates today and the rest is released evenly over four years. Each year, more tokens join the float:

Hold the price fixed at $1 for the sake of illustration and market cap climbs toward FDV as tokens are released, the two meeting once the full supply trades. Real life won’t be that tidy — new supply has to find buyers — which is precisely why FDV is a projection and not a promise. The timeline behind the gap matters as much as the gap.

The limitations of FDV

FDV is handy for spotting pending dilution. But it leans on assumptions that often don’t hold, and it’s easy to abuse:

• It assumes today’s price across all supply. Stamping the current price onto tokens that won’t exist for years is a strong claim. Prices move, and a market forced to absorb far more supply may not hold the same price per token.
• Emission schedules vary and can change. The pace at which locked tokens arrive differs from project to project, and some schedules can be rewritten by governance. A single FDV number buries the timeline completely.
• “Maximum supply” isn’t always well defined. Some tokens have no hard cap, so their supply grows without end; for those, FDV is ambiguous or basically meaningless, and providers may fall back on total supply instead.
• Low-float, high-FDV distortions. A project with only a small circulating float can pair a modest market cap with an enormous FDV. That big FDV can make an asset look bigger than the market that actually trades it, and the supply still to come will need buyers.

So treat FDV as a supply-awareness tool — not a target, and not a fair-value estimate.

FDV vs circulating market cap: which to use

There’s no single right answer; the two do different jobs:

• Use market cap to compare assets by how they trade today, based on what’s genuinely in circulation.
• Use FDV to see how much extra supply is still coming, and how diluted current holders could become as it lands.

Reading only one of them is where people go wrong. A low market cap can look tempting while a towering FDV flags heavy dilution ahead; a market cap sitting close to FDV says most of the supply is already out. The relationship between the two tells you more than either figure by itself.

Why FDV became a talking point

FDV gets loud around new token launches, and the reason is structural. A freshly launched token often trades only a small fraction of its supply at first, with the bulk released over the following years. In that setup, market cap can look small while FDV runs very large, and the difference between them is essentially a preview of the supply early holders will be diluted against. Read only the market cap and you can walk away with a misleadingly tiny impression of the token’s scale. That’s why FDV gets quoted next to market cap for recent launches — not because it’s the better number, but because it exposes what the circulating figure hides. It’s context, not a verdict: a way to ask how much supply is still coming, and over what period, before you conclude anything.

The bottom line

Fully diluted valuation stretches today’s price across a coin’s entire eventual supply, giving you a projection of size under full dilution. It’s genuinely useful for surfacing pending supply that plain market cap keeps out of sight. It also assumes a static price across tokens that may not exist for years, depends on emission schedules that vary and can shift, and falls apart for uncapped tokens. So keep it as one lens among several — compare it with circulating market cap, and learn the release timeline behind the gap rather than reading the headline on its own.
