Market cap vs FDV: what’s the difference?

Reading on-chain data·5 min read·Updated August 14, 2026

Market capitalisation and fully diluted valuation (FDV) are two of the most quoted — and most confused — numbers in crypto. They answer different questions, and the gap between them can quietly hide enormous future sell pressure. Reading both is essential before you value any token.

The two definitions

Market cap = current price × circulating supply — the tokens actually in the market today. FDV = current price × total (or maximum) supply — the value if every token that will ever exist were already trading. When a large share of supply is still locked or unminted, FDV can dwarf market cap.

Why the gap is a warning sign

A token with a $50M market cap but a $2B FDV has 40× more supply waiting to enter circulation. As those tokens unlock — team, investors, emissions — they add sell pressure that the current price may not survive. A wide market-cap-to-FDV gap is one of the clearest structural risks in a token.

  • Market cap ≈ FDV → most supply is already liquid; fewer unlock shocks ahead.
  • FDV ≫ market cap → heavy future dilution; check the unlock schedule.
  • Neither number tells you whether a price is tradeable — that takes liquidity.

Why liquidity beats both

Market cap and FDV both multiply price by a supply number, so a thin, manipulable price inflates them equally. On-chain liquidity is harder to fake: it is real value locked in pools. That is why CoinVerum leads with liquidity — read reading on-chain liquidity for how to judge whether a valuation is real.

Frequently asked questions

Which matters more, market cap or FDV?

Both. Market cap reflects today’s tradeable value; FDV warns you about future dilution. A healthy project has a manageable gap between them and a transparent unlock schedule.

Why is FDV sometimes misleading?

FDV assumes all supply is valued at today’s price, which rarely holds — large unlocks usually push the price down. It is a ceiling scenario, not a prediction.

How does CoinVerum calculate market cap?

CoinVerum multiplies its on-chain-derived price by circulating supply, so the figure inherits the verifiability of an on-chain price rather than a blended or CEX-led feed.
