Look up PUMP on two sites and you can see two different dollar valuations at the same moment, and each one is defensible. Every valuation multiplies the same price by a different pile of coins, so the answer depends entirely on which coins you count. Market cap uses the coins actually circulating, while fully diluted value uses a larger base that includes supply still to come. For PUMP those bases disagree by a wide margin, and one of them is the issuer's original headline number that the blockchain has since moved past.
Market cap and fully diluted value
The choice of market cap versus fully diluted value comes down to one thing: which pile of coins you multiply the price by. Two figures get thrown around as if they mean the same thing, yet they measure different things. Market cap is the price times the coins in circulation right now, so it answers a narrow question: what the tradable part of the supply is worth today. Fully diluted value multiplies the same price by the whole supply, including coins still locked or waiting to be minted, so it answers a broader question: what the whole thing would be worth if every coin were already in the market at this price. The wider the gap between circulating and total supply, the further these two numbers sit apart.
Why PUMP has three supply denominators
PUMP offers three different totals to multiply by, and each one produces a different valuation. All figures below are as of the date shown and move with the price, so check them live before you rely on them.
The first base is the circulating supply, around 415 billion PUMP. At a price near $0.0044 that gives a market cap of roughly $1.84 billion (source: CoinGecko). The second base is the amount actually minted on-chain, about 835 billion, and multiplying that by the same price gives a fully diluted value near $3.7 billion, which is how CoinGecko builds its FDV, on the on-chain total rather than the stated maximum.
The third base is the issuer's original stated total of one trillion, published on the coin's own page (source: pump.fun) and used as the fully diluted base by CoinMarketCap (source: CoinMarketCap). One trillion at the same price is about $4.44 billion.
Same token, same second, three defensible valuations sit side by side: roughly $1.84 billion, $3.7 billion, and $4.44 billion.
Where the gap comes from
The gap between the last two numbers is a real, checkable mismatch rather than a rounding quirk. The issuer's page still states the original one-trillion total, while the mint on Solana reports well below that, around 835 billion, because supply has fallen since launch. That difference of roughly 165 billion coins is concrete: at the current price it is worth about $730 million of fully diluted value, purely from which total you decide to trust.
This is why you can find "two" fully diluted values live at once: one built on the stated one trillion, one built on the smaller on-chain number. Both are honest, and they simply count different coins, a split PUMP tokenomics and supply lays out in full.
The arithmetic, so you can redo it
Anyone can check this by hand, because fully diluted value is simply the price times a supply number that you choose yourself.
Say you are checking PUMP at a price of $0.0044. Take the on-chain total first, where 835 billion times $0.0044 works out to about $3.7 billion, then take the stated total, where one trillion times $0.0044 works out to about $4.44 billion. Subtract one from the other and the gap is about $730 million. Do the same with the circulating supply, 415 billion times $0.0044, and you land near $1.84 billion, which is the market cap. Three multiplications give three numbers, and you can see exactly which coin count drives each one, so when the price changes you simply redo the multiplication with the new figure.
What the burn does to each base
PUMP's supply shifts over time. Coins get bought back and burned, which lowers both the amount in circulation and the amount minted on-chain, a process PUMP buyback and burn explained covers in detail.
Burning pulls down the real bases, so the circulating figure and the on-chain total both fall as coins are destroyed. The one number that stays fixed is the issuer's stated one trillion, because it is a published headline rather than a live on-chain count. The more that gets burned, the wider the gap grows between a fully diluted value based on the stated total and one based on the coins that actually exist, so a valuation resting on the one-trillion figure drifts further from reality with every burn.
If you decide to act on any of these numbers, the PUMP/USDT market is where the token changes hands, and because the live bases keep shrinking, the running cost of holding a position matters as much as the headline valuation, which BloFin lists on its fee schedule.
Which number should you use
Each valuation answers a different question, so pick the base that matches yours instead of accepting whichever one a site shows first. If you care about what is liquid and tradable today, the circulating market cap is the honest figure. If you care about dilution, meaning how much value is implied when the whole real supply reaches the market, use a fully diluted value built on the on-chain total instead of the stated one. Treat the one-trillion-based number as a ceiling that assumes coins the chain has already burned away. What moves any of these figures day to day is covered in what moves the PUMP price.

Frequently asked questions
Why does PUMP show different market caps on different sites?
Because each site multiplies the price by a different supply number. Some use the circulating supply, some use the on-chain total, and some carry the issuer's stated total. The price is the same everywhere, so the differences come entirely from which pile of coins each site counts.
What is the difference between market cap and FDV for PUMP?
Market cap is the price times the circulating supply, around $1.84 billion at recent prices. Fully diluted value multiplies the price by a larger base, either the roughly 835 billion minted on-chain or the stated one trillion, which puts it near $3.7 billion or $4.44 billion. The price stays the same, but a bigger coin count produces a bigger number.
Why is there a gap between PUMP's stated supply and its on-chain supply?
The issuer's page still lists the original one-trillion total, while the mint on Solana reports around 835 billion because supply has been reduced since launch. That mismatch of roughly 165 billion coins is worth hundreds of millions of dollars of fully diluted value at the current price, depending on which total you use.
Which valuation of PUMP is the correct one?
All three answer different questions, so each is right for its own purpose. Use the circulating market cap for what is tradable now, and a fully diluted value based on the real on-chain supply for dilution. The figure built on the stated one trillion is best read as an upper bound.
How do I calculate PUMP's fully diluted value myself?
Multiply the current price by whichever total supply you want to test. At a price near $0.0044, the on-chain total of about 835 billion gives roughly $3.7 billion, and the stated one trillion gives about $4.44 billion. Redo the multiplication whenever the price changes.
