Circulating Supply

Circulating supply is the number of coins or tokens that are publicly available and actively trading. It excludes tokens that are locked, reserved, or not yet released, and it is the figure used to calculate market capitalization.

How it works

Circulating supply sits between two other measures. Total supply counts all tokens that currently exist minus any that have been verifiably burned. Maximum supply is the hard cap that will ever exist, if one is defined. Circulating supply can grow over time as locked or unminted tokens are released through emissions, staking rewards or vesting schedules.

Why it matters

Because market cap depends on it, the circulating supply figure directly shapes how large an asset appears. Tokens with a small circulating supply but a large total supply can face future “unlock” pressure as more tokens enter the market, which is an important part of reading a project’s tokenomics.

Example

Bitcoin’s circulating supply rises slowly toward its fixed maximum of 21 million as miners receive block rewards.

Circulating Supply: Frequently Asked Questions

How is circulating supply different from total and maximum supply?
Circulating supply is the portion publicly available and trading. Total supply counts all tokens that currently exist minus any verifiably burned. Maximum supply is the hard cap that will ever exist, if one is defined. Circulating supply sits between these, and it is the figure used to calculate market cap.
Why does circulating supply matter for price?
Market cap is price multiplied by circulating supply, so the circulating figure directly shapes how large an asset appears. Two coins with similar prices can have very different market caps depending on supply. It is a key input when comparing valuations, but it should be read alongside total and maximum supply.
Can circulating supply increase over time?
Yes. Circulating supply can grow as locked or unminted tokens are released through emissions, staking rewards, or vesting schedules. Tokens with a small circulating supply but a large total supply can face future "unlock" pressure as more enter the market. Bitcoin's circulating supply, for example, rises slowly toward its fixed maximum of 21 million.
