Market Cap vs. FDV: The Meme Coin Math Traders Skip
By Alphacino Editorial Team ·
Quick Take
Market cap tells you what a meme coin is worth right now; FDV tells you what it could be worth once every token hits the market, and the gap between them is where bags get diluted.
Every token page flashes two big numbers: market cap and FDV. Most meme traders glance at the first, ignore the second, and ape. That works until it doesn't.
Market cap is circulating supply multiplied by current price. It's what the market is actually paying for the tokens that are tradable today. Fully diluted value, or FDV, is total supply multiplied by the same price. It's the theoretical valuation if every single token were already out in the wild, including anything locked, vested, or sitting in a team wallet.
Here's the good news for Solana degens: on a standard pump.fun launch, the two numbers are usually identical. The entire supply is minted at launch and sold along the bonding curve, so there's no hidden pile of tokens waiting to unlock. When market cap equals FDV, what you see is what you get.
The trouble starts when they don't match. A meme coin showing a $5M market cap but a $50M FDV means only a tenth of supply is circulating. The rest is coming eventually, whether through vesting schedules, team allocations, or so-called community treasuries. Every unlock is fresh supply hitting the order book, and unless buyers grow just as fast, price has to give.
So make it a habit. Before you buy, check whether market cap and FDV line up. If they don't, find out who holds the gap and when it unlocks. A big spread isn't automatically a rug, but it's a dilution risk you should price in, not discover after the dump.
