When evaluating a crypto asset, two numbers often appear together:
- Circulating Supply
- Fully Diluted Valuation (FDV)
Understanding the difference between them is essential for assessing potential dilution, tokenomics structure, and long-term valuation risk.
They measure two different versions of value — present and theoretical future.
What Is Circulating Supply?
Circulating supply refers to the number of tokens currently available and tradable in the market.
It excludes:
- locked tokens
- team allocations under vesting
- treasury reserves not yet released
- future emissions
Market capitalization is calculated using circulating supply:
Market Cap = Current Price × Circulating Supply
This reflects the asset’s current live valuation.
What Is Fully Diluted Valuation (FDV)?
Fully Diluted Valuation assumes that all tokens that will ever exist are already in circulation.
It uses the total maximum supply instead of circulating supply:
FDV = Current Price × Maximum Supply
FDV represents the project’s theoretical valuation if every token were unlocked today.
It reflects future supply potential.
Why the Difference Matters
A large gap between market cap and FDV signals significant future token unlocks.
If many tokens are scheduled to enter circulation:
- supply may increase over time
- dilution risk rises
- selling pressure may appear during unlocks
High FDV relative to current market cap suggests more tokens are coming.
Example Scenario
If:
- Circulating Supply = 100 million
- Maximum Supply = 1 billion
- Token Price = $1
Then:
- Market Cap = $100 million
- FDV = $1 billion
This means only 10% of total supply is circulating.
Future releases could impact price if demand does not grow proportionally.
Dilution Risk
Projects with:
- large vesting schedules
- heavy emission programs
- long-term token unlocks
may experience gradual supply expansion.
If demand remains stable while supply increases, price pressure may occur.
Dilution is structural, not speculative.
When FDV Is Less Concerning
If:
- most supply is already circulating
- emissions are minimal
- vesting schedules are nearly complete
then FDV and market cap may be close.
Lower future supply expansion reduces uncertainty.
Investor Perspective
Circulating supply shows current valuation.
FDV shows potential future valuation.
Evaluating both helps answer:
- How much supply remains locked?
- When will it unlock?
- Can demand absorb future tokens?
Long-term sustainability depends on supply trajectory.
Final Thoughts
Circulating supply measures current tradable tokens and determines market capitalization.
Fully diluted valuation estimates total valuation if all tokens were released.
The gap between the two highlights potential dilution risk — and helps investors assess how future supply expansion may influence price stability.
