Fully diluted valuation (FDV) is the theoretical market cap of a crypto project if every token that will ever exist were in circulation today. It equals the current token price multiplied by the total maximum supply. FDV is forward-looking: it tells you what the market would be worth if no tokens are burned and all scheduled emissions, team allocations, and vesting tranches have been released.
How FDV is calculated and why it matters
A token with 100 million in circulating supply, 1 billion in total max supply, and a price of $5 has a market cap of $500 million and an FDV of $5 billion. The $4.5 billion gap represents tokens that do not yet exist in the circulating market but will over the coming years. If demand stays constant as those tokens enter circulation, the price must fall by 90% just to maintain the same market cap. Growth in protocol usage and revenue can absorb some of that dilution; speculative demand rarely can.
Low circulating supply at launch (below 10%) combined with a high FDV means most of the token supply is in the hands of insiders at a cost basis far below the launch price. That is who will be selling when vesting schedules release.
What this means for traders
Comparing FDV across similar protocols gives a relative valuation metric. A protocol with $200 million FDV and $20 million in daily volume is cheaper than one with $2 billion FDV and the same volume by most metrics. FDV vs. market cap divergence is one of the clearest sell-pressure signals available before a major unlock event: a large gap between the two means substantial future supply is coming.
For the supply mechanics behind FDV, see tokenomics explained and token vesting explained. Those two articles cover the specific schedules that determine when the FDV converges toward market cap.
A concrete example
Protocol A launches with 50 million tokens circulating (5% of a 1 billion total supply) at $2 per token. Market cap: $100 million. FDV: $2 billion. Over three years, 950 million more tokens enter circulation through team vesting, investor unlocks, and emission rewards. For the FDV to remain correct at $2 billion, the protocol must grow its fundamental value by roughly 19x to absorb that supply without price dilution. If it grows 5x in genuine usage, price falls proportionally. If usage does not grow, the entire additional supply is pure dilution.
Frequently asked questions
Should I use FDV or market cap when comparing projects?
Use both and note the ratio. A project where FDV is within 2x of market cap has most of its supply circulating, with relatively low future dilution risk. A project where FDV is 10x market cap has substantial future supply incoming. Neither is automatically bad; it depends on whether the vesting timeline and growth trajectory justify the gap.
Is a low FDV always better?
Not necessarily. A low FDV can mean a depressed price, a small total supply with limited ecosystem role, or that very few tokens are yet circulating. Context matters. Check the circulating supply percentage alongside the FDV, and compare against similar protocols in the same category.
What happens to FDV when tokens are burned?
Token burns reduce total supply, which reduces FDV for protocols with ongoing burn mechanisms. Ethereum’s EIP-1559 burns a portion of every transaction fee. Binance burns BNB quarterly. For these protocols, FDV converges toward market cap over time rather than diverging, because the maximum supply shrinks rather than grows.
