What is the difference between market cap and fully diluted valuation (FDV)?

Short answer

Market cap is the token's price times its circulating supply. Fully diluted valuation (FDV) is the same price times the total or max supply, as if every token were already out.1,2 A big gap between the two means many tokens are still to be released.2,3

Market cap

CoinGecko's formula for a token's market capitalisation, or market cap, is its current price times its circulating supply.1 CoinMarketCap uses the same formula.2

CoinGecko gives its own example. With 583,209,787 ZRX tokens circulating at $0.25 each, the market cap is $145,802,446.75.1

Fully diluted valuation

Fully diluted valuation, or FDV, asks a different question. What would all the tokens be worth together if every one of them were already in circulation, at today's price?4

The sites don't all agree on what "every token" means.4,5,2

CoinMarketCap says that for most tokens, total supply and max supply are the same number, so FDV is clear. For some they differ a lot.7 CoinGecko's guide adds that some tokens show no FDV at all, because they have no max supply.4

The ratio

CoinGecko shows a "Market Cap / FDV" figure. The closer it is to 1, the closer market cap is to FDV.4 CoinMarketCap turns it upside down: FDV ÷ market cap, which it says shows how much issuance is still ahead.2

The price cancels out. Market cap ÷ FDV is simply circulating supply ÷ the supply used for FDV.4,2

On 7 October 2026, CoinMarketCap measured FDV ÷ market cap at 1.00 for Ethereum and 2.63 for Worldcoin. Bitcoin was just above 1.00, because about 4.3% of its coins are still to be mined.2 CoinMarketCap added: "That is not a prediction about price."2

Low float, high FDV

In May 2024, Binance Research, the research arm of the Binance exchange, published a report called "Low Float & High FDV". By low float it meant tokens launching "with low circulating supply" and high valuations.3

  • The numbers. It put the market cap to FDV ratio of tokens launched so far in 2024 (data to 14 April 2024) at 12.3%. Among several recent launches it picked as examples, circulating supply was as low as 6% and none was above 20%.3
  • Its view. It said a large amount of tokens coming onto the market poses selling pressure unless buying demand grows to match.8
  • A warning about FDV. It also said FDV on its own does not paint a complete picture.3

CoinGecko's guide says whether an FDV is realistic is "a mere presumption" with a wide margin of error.4

How we work out market cap and FDV

Market cap = price × circulating supply. FDV = price × total supply, or price × max supply; say which.1,4,5

Example: 160,000,000 tokens circulating, a max supply of 1,000,000,000, and a price of $0.25. Market cap = $40,000,000. FDV = $250,000,000. Market cap ÷ FDV = 16%. The quizzes use these methods.

Our viewFDV is a calculation, not a price anyone has paid. Its real use is to show how much supply is still to come.
