Market cap is price multiplied by circulating supply. Fully diluted value is price multiplied by total supply — everything that exists or will exist, including tokens locked, vesting or held back. For most Solana memecoins the two numbers are identical because the entire supply is minted at launch and immediately circulating. When they differ, the gap is the whole story: it measures how many tokens are waiting to reach the market, and every one of them is future sell pressure priced as though it were already there.
Key Facts
- Market cap = price × circulating supply. FDV = price × total supply.
- Identical numbers mean everything is already in circulation, typical for fair-launch memecoins.
- A large gap means locked, vesting or reserved tokens will enter the market later.
- Neither figure reflects how much money is actually in the pool — that is liquidity, a separate number.
- Both are calculated from the last trade price, so a thin pool produces a large but meaningless cap.
- Burned tokens should be excluded from both, but some data sources still count them.
- Pump.fun graduation happens at roughly $69,000 market cap, which is the same as FDV there.
Why the Gap Matters
Suppose a token trades at a $10M market cap with a $40M FDV. That means three quarters of the eventual supply is not yet circulating — held in a team allocation, a vesting contract, or an unreleased treasury. Whoever holds those tokens acquired them before the public market existed, so they can sell profitably at prices far below where anyone buying today entered.
Buying at market cap when FDV is four times higher is buying into a queue. The current price reflects demand against a quarter of the supply; the remaining three quarters arrives on a schedule you did not set. This is the arithmetic behind why presale allocations matter, and why fair launches, where the two numbers match by construction, remove the question entirely.
The Three Numbers That Get Confused
| Market cap | FDV | Liquidity | |
|---|---|---|---|
| Formula | Price × circulating | Price × total supply | Actual assets in the pool |
| What it measures | Value of tradable supply | Value if everything circulated | What you can actually exit into |
| Can be inflated by a thin pool | Yes | Yes | No |
| Predicts future sell pressure | No | Via the gap | No |
| Determines your exit price | No | No | Yes |
The bottom row is the one that costs money. A token can show a $5M market cap with $30,000 of liquidity in the pool, which means the headline number is a multiplication of a price nobody can actually transact at in size. Market cap and FDV both derive from the last trade, and one small buy against a shallow pool can move that price a long way. Reading market cap on a launchpad is only meaningful alongside the pool depth behind it.
The Comparison Trap
“This token is only $2M, DOGE is $20B, so it could do a thousand x” is the most common bad reasoning in memecoin trading, and the FDV distinction is half of why it fails. The other half is that market cap is not money invested. A $2M cap does not mean two million dollars entered the token — it means the last trade price times supply equals two million, and the actual capital in the pool might be $40,000. Growing that cap tenfold requires real buying pressure against real depth, not a re-rating of a number.
Comparing tokens honestly means comparing three things at once: FDV for the supply picture, liquidity for the exit picture, and holder distribution for the concentration picture. Reading the top holder list completes what the cap numbers leave out, because a low FDV with 40% in three wallets is worse than a higher FDV that is genuinely distributed.
Where to Read Them Accurately
CoinGecko shows market cap and FDV side by side for listed tokens, which makes the gap immediately visible. For unlisted memecoins, DEXScreener shows market cap, FDV and pool liquidity on the same pair page — read all three together rather than any one. Watch for burned supply being counted: if a project burned 40% of tokens, honest figures exclude them, and a source that does not will overstate both cap and FDV significantly.
Why $DOLAN’s Two Numbers Are the Same
DOLAN Duck ($DOLAN) has a fixed 98.3M supply, all of it minted at launch and circulating, held across roughly 10,700 holders. Market cap and FDV are therefore identical, which is not an achievement so much as a consequence of fair launching with no vesting schedule — there is no tranche to unlock, so there is nothing for the gap to measure. The useful habit this illustrates applies to any token: check whether the two figures match before anything else, because a match closes an entire category of question in one glance, and a mismatch tells you to go find out who holds the difference and when it unlocks. Then check liquidity separately, because neither number says anything about what a price on a chart actually means if the pool behind it is thin.
Market cap is price times circulating supply. FDV is price times total supply, including tokens that are locked, vesting or not yet released. The gap between them is future sell pressure.
Because the entire supply is usually minted at launch and immediately circulating. With no vesting or reserved allocation, there is nothing outside circulation for FDV to count.
No. Both are the last trade price multiplied by a supply figure. The actual capital in the pool is liquidity, a completely separate number that is often a tiny fraction of market cap.
It means most of the supply has not reached the market yet. Whoever holds it acquired it before public trading and can sell profitably far below where current buyers entered.
Liquidity. Market cap and FDV describe supply valuation; only pool depth determines what you can actually sell into and at what price impact.
They should be excluded from both figures, but some data sources still count them. A project that burned a large share of supply will show inflated numbers on any source that does not adjust.
Compare FDV rather than market cap, then check pool liquidity and holder concentration alongside it. A low FDV with supply concentrated in a few wallets is worse than a higher, well-distributed one.
