What is fully diluted valuation (FDV)?

Fully diluted valuation, or FDV, is the market capitalisation a cryptocurrency would have if every token that will ever exist were already in circulation at today’s price. Where ordinary market cap uses only the circulating supply, FDV uses the maximum (or total) supply, which makes it a projection of size under full dilution rather than a measure of the market today.

This article explains how fully diluted valuation is calculated, how it differs from market cap, and where it can mislead. It is educational only and describes a metric; it is not a valuation judgement or a reason to act.

What fully diluted valuation measures

The formula mirrors market cap but swaps the supply input:

FDV = current price × maximum supply

Maximum supply is every token the protocol will ever create, including those still locked in vesting, held in reserve, or not yet minted. By pricing all of them at the current market price, FDV answers a hypothetical question: if the entire supply were circulating today and the price stayed the same, how large would this asset be? Because it counts tokens that are not yet tradable, FDV is almost always larger than market cap — sometimes by a small margin, sometimes by many multiples.

An illustrative example

These figures are invented to show the arithmetic. They are not market data and do not describe any real asset.

Here only 10% of the supply is circulating, so FDV is ten times the market cap. The remaining 900 million tokens are scheduled to enter circulation over time. That gap between the two numbers is the whole point of looking at FDV: it makes visible how much supply is still to come.

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 pending. A large gap means a big share of tokens is still locked and will unlock later, through vesting schedules, staking emissions, or ongoing minting. As those tokens reach the market, circulating supply rises and market cap converges toward FDV — but only if the price holds, which it need not.

This is why the two figures should always be read together. Market cap reflects what is priced and tradable today; FDV reflects the size implied by the full supply. We cover the inputs separately in what is market cap in crypto and what is circulating supply. Neither number is the “true” value — they answer different questions.

Reading the FDV-to-market-cap ratio

One practical way to use FDV is as a ratio against circulating market cap. Dividing FDV by market cap — or equivalently comparing maximum supply to circulating supply — gives a quick sense of how much of the eventual supply is already in the market:

• A ratio close to 1 means market cap and FDV are nearly equal, so almost all tokens are already circulating and little future dilution is pending.
• A large ratio (FDV several times market cap) means only a small slice of supply is circulating and a lot is still locked, so significant dilution is scheduled ahead.

Neither reading is inherently good or bad; they simply describe where a token sits in its distribution. A high ratio is not a criticism and a low ratio is not an endorsement — both are just facts about supply that put the headline numbers in context.

How the gap closes: an illustrative timeline

These figures are invented to show the mechanism, not real data. Imagine a token where 10% of supply circulates today and the rest unlocks evenly over four years. Each year, more tokens enter circulation:

Holding the price fixed at $1 for illustration, market cap climbs toward FDV as tokens unlock, and the two converge once the full supply circulates. In reality the price will not stay fixed — new supply must find buyers — which is exactly why FDV is a projection rather than a promise. The timeline behind the gap is as important as the gap itself.

The limitations of FDV

FDV is useful for spotting pending dilution, but it rests on assumptions that often do not hold, and it is easy to misuse:

• It assumes today’s price across all supply. Applying the current price to tokens that will only arrive years from now is a strong assumption. Prices change, and the market that must absorb a much larger supply may not sustain the same price per token.
• Emission schedules vary and can change. The pace at which locked tokens unlock differs by project, and some schedules can be altered by governance. A single FDV number hides the timeline entirely.
• “Maximum supply” is not always well defined. Some tokens have no hard cap, so their supply grows indefinitely; for these, FDV is ambiguous or effectively meaningless, and providers may use total supply instead.
• Low-float, high-FDV distortions. A project with only a small circulating float can show a modest market cap alongside an enormous FDV. The large FDV can make an asset look bigger than its actual traded market, and the coming unlocks represent supply that will need buyers.

Because of these limitations, FDV is best read as a supply-awareness tool, not as a target or a fair-value estimate.

FDV vs circulating market cap: which to use

There is no single correct choice; the two serve different purposes:

• Use market cap to compare the size of assets as they trade today, based on what is actually in circulation.
• Use FDV to understand how much additional supply is still to come and how diluted the current holders could become as it does.

Reading only one of them is where mistakes happen. A low market cap can look appealing while a towering FDV signals heavy future dilution; a market cap close to FDV signals that most of the supply is already circulating. The relationship between the two is more informative than either figure alone.

Why FDV became a talking point

FDV draws particular attention around new token launches, and the reason is structural. A newly launched token often circulates only a small fraction of its supply at first, with the bulk released over subsequent years. In that setting, market cap can look modest while FDV is very large, and the difference between the two is essentially a preview of the supply that early holders will be diluted against. Reading only the market cap in such cases can give a misleadingly small impression of the token’s scale. This is why FDV is frequently cited alongside market cap for recent launches: not because it is a better number, but because it exposes information that the circulating figure alone hides. As always, it is context rather than a verdict — a way to ask how much supply is still to come, and over what period, before drawing any conclusion.

The bottom line

Fully diluted valuation extends today’s price across a coin’s entire eventual supply, producing a projection of size under full dilution. It is valuable for seeing pending supply that ordinary market cap hides, but it assumes a static price across tokens that may not exist for years, it depends on emission schedules that vary and can change, and it is undefined for uncapped tokens. Treat FDV as one lens among several: always compare it with circulating market cap, and understand the unlock timeline behind the gap rather than reading the headline number on its own.
