FDV vs Market Cap: How to Actually Value a Solana Memecoin

Two numbers sit at the top of every DexScreener page, and most traders read one of them by accident. "Market cap" and "FDV" look like the same idea dressed up twice, so people glance at whichever is smaller, decide the token is "still cheap," and buy. That habit is exactly how a token with a tiny circulating float and a mountain of locked supply talks you into paying a top price. Understanding what each number measures — and what the gap between them is telling you — is the difference between valuing a memecoin and guessing at one. This is how to read both and run a quick valuation check before you press buy.

Two numbers, two questions

Market cap and fully diluted valuation answer different questions, and the trap is treating them as interchangeable. Market cap is the value of the tokens in circulation right now: circulating supply multiplied by the current price. It answers "what is the market valuing the float at today?" FDV — fully diluted valuation — is total (or maximum) supply multiplied by the same price. It answers "what would this project be worth if every token that will ever exist were already trading at this price?"

The formulas are simple:

• Market cap = circulating supply × price
• FDV = total / max supply × price

Notice that price is the same in both. The only thing that changes is which supply number you multiply by. So whenever FDV is bigger than market cap, it is because some of the supply is not circulating yet — it is locked, vested, reserved, or otherwise sitting off to the side waiting to come online. The size of that gap is the whole story.

Why for most memecoins they are almost the same

Here is the part that surprises people: for the typical pure memecoin, market cap and FDV are roughly equal, and the distinction barely matters. That is a function of how these tokens are minted. A standard Pump.fun-style launch creates a fixed supply of about one billion tokens, and effectively all of it is put on the bonding curve from the start. There is no team tranche vesting over two years, no seed-round allocation unlocking next quarter — the supply is fully out in the open. Total supply equals circulating supply, so circulating × price and total × price land on the same figure.

When the mint authority has been revoked (no new tokens can be created) and the supply is fully on the curve, market cap and FDV converging is the expected, healthy reading. DexScreener reflects this: it looks for a self-reported circulating supply and uses that for market cap, and for tokens that do not hold back supply, FDV and market cap come out identical. (When a token does not report a circulating supply, some trackers fall back to total supply for the market-cap figure, so the two can match by default rather than because the float genuinely equals the total — worth keeping in mind.) The takeaway: for a fair-launch memecoin, do not overthink the split. It is the tokens where the two diverge that demand your attention.

Where the gap actually bites: low float, high FDV

The distinction stops being academic the moment a token has locked, vested, team, or treasury allocations. Picture a token where only ten percent of the supply is circulating and the other ninety percent is held back for the team, early investors, and a "community treasury" on a vesting schedule. A small float means a relatively small amount of buying walks the price up fast — and that inflated price is then multiplied across the entire supply to produce a headline FDV that looms far above the market cap.

That is the low-float, high-FDV setup, and it is where holders get hurt. A thin slice of circulating tokens props up the price while a huge reservoir waits in the wings. As those locked tokens unlock — often in a cliff, where nothing releases for months and then a big tranche hits at once — they pour in as fresh sell pressure. The people receiving them (team, advisors, seed investors) frequently have a cost basis near zero, so selling at almost any price is rational. You are diluted, and the float that was holding the price up is suddenly competing with a wave of supply that has every reason to sell.

This is why a "cheap, low market cap" can be a trap. A token showing a four-million-dollar market cap might carry a forty-million-dollar FDV. You think you are buying something small with room to run; in reality the market already values the full project at forty million, and the next year of unlocks is a structural headwind on the price unless real demand grows faster than supply arrives. The headline that looked cheap was the circulating slice; the price you are really paying into is the FDV.

How to actually check supply and concentration

You do not have to take the headline numbers on faith — the data is on-chain and a couple of tabs away. Before sizing a position, pull these:

• Circulating vs total supply. On the DexScreener pair page, compare the market cap and FDV fields directly. If they are close, the supply is largely circulating. If FDV is a multiple of market cap, a large share is locked or unissued — find out how much and on what schedule. Learning to read the page field by field is covered in our DexScreener walkthrough.
• Holder concentration. Open the token on an explorer and look at the top-holder list. A handful of wallets holding the bulk of the supply means a few actors can dump on you regardless of what the chart says. Solscan shows the holder distribution and lets you check whether the top wallets are an exchange, a locker contract, or just somebody's personal stash.
• Mint and freeze authority. If the mint authority is still active, the supply number is not even fixed — more tokens can be created, which is dilution with no schedule at all. Confirm it has been revoked.
• Liquidity vs market cap. A small pool under a large cap means the price is fragile no matter how the supply is split. Liquidity decides whether you can exit, and that is its own red-flag check — see the due-diligence checklist.

Reading the chart matters too, but the chart only shows where the price has been. Supply and concentration tell you what can happen to that price next. If you want to pair the two skills, reading the chart and reading the supply are the two halves of the same decision.

Compare by market cap, not token price

Once you can read the numbers, here is how to use them: compare tokens by market cap, never by per-token price. "This one is only $0.0000004, it has so much more room than the $0.04 one" is the single most expensive misconception in memecoin trading. Price per token is meaningless on its own — it depends entirely on how many tokens exist. A token at four-millionths of a dollar with a billion supply and one at four cents with a hundred-thousand supply can have the exact same market cap. The number of zeros tells you nothing about how big the project already is.

Market cap is the apples-to-apples figure, and it is also how you set a realistic target. Instead of "I hope this pumps," ask: what would have to be true for a 10x? A token at a four-million market cap doing a 10x reaches forty million — the range of mid-tier established memecoins, which takes real, sustained attention and volume. A token already at eighty million doing the same 10x would need eight hundred million, which is a small handful of tokens in the entire market. Framing the target as a market cap forces you to confront whether the move you want is plausible or fantasy. And when a token has a low float, run that math on the FDV too — the unlocks coming online are part of what your 10x has to fight through.

The limits of these numbers for memecoins

Stay honest about what market cap and FDV can and cannot do. For blue-chip assets these figures are a reasonable proxy for value. For memecoins they are a starting frame, not a verdict — and two things matter more than either headline number.

The first is liquidity and exit-ability. A token can show an attractive market cap and still be a roach motel if the pool is thin: you get in, but any meaningful sell craters the price and you cannot get out near the quoted value. A realistic cap on a deep pool is worth far more than a flashy one on a puddle. The second is that a memecoin's "value" is mostly attention and narrative, which no supply formula captures. Market cap and FDV tell you how the supply is structured and what dilution is coming; they do not tell you whether anyone will still care tomorrow. Use them to disqualify traps — enormous hidden FDV, mint still live, top wallets holding everything — more than to confirm winners.

A quick pre-buy valuation checklist

Before you size a position, run through this — it takes under a minute once it is habit:

1. Compare market cap to FDV. Close together is healthy. A large gap means hidden supply — find the unlock schedule before you buy.
2. Confirm the mint authority is revoked. If it is live, the supply is not fixed and "FDV" is a moving target.
3. Check holder concentration. If a few wallets hold most of the supply, assume they can and will dump on you.
4. Judge the cap, not the token price. Ignore the zeros. Ask whether the current market cap is reasonable for what the token actually is.
5. Frame your target as a market cap. Decide what a 2x or 10x means in absolute valuation and whether that number is plausible. Run it against FDV too if the float is low.
6. Confirm you can exit. Check that liquidity is deep enough to sell into. A valuation you cannot realize is not a valuation.

How MoonHydra fits

A valuation thesis is only useful if you can act on it cleanly, and that is the part MoonHydra handles. It is a non-custodial Solana trading bot that lives in Telegram: your keys are encrypted with AES-256-GCM and never leave your control, and every swap routes through Jupiter for best execution — there are no custom contracts in the path, just the established Solana DEX infrastructure. Pricing is a flat 1% per trade on buys and sells, with no subscription, so the cost of acting on your read is predictable.

Once you have decided a token's market cap is reasonable and its FDV is not hiding a dilution cliff, MoonHydra lets you execute the plan. Position cards show your actual holdings and live PnL so you can track the thesis as it plays out, and wallet tracking lets you watch the wallets you care about — including whether large holders start moving toward an exit. Limit orders and TP/SL let you encode your valuation targets in advance: set a take-profit at the market cap you decided was your 10x, and a stop in case the unlock-driven sell pressure you flagged actually arrives. The numbers tell you what to do; the bot is how you do it without watching a chart all day.

Bottom line

Market cap is circulating supply times price; FDV is total supply times price. For a fair-launch memecoin with a fixed, fully circulating supply, the two are nearly identical and the distinction is minor. The distinction matters when a token has locked, vested, or team allocations: a small circulating float can prop up the price while a huge FDV looms overhead, and every unlock dilutes you. A "cheap low market cap" is a trap when the FDV is enormous. Always compare tokens by market cap rather than token price, frame your targets as absolute valuations, and remember that for memecoins, liquidity and exit-ability outweigh any headline number. The cap is a frame for the decision, not the decision itself.
