PUMP has two supply forces working against each other, and which one wins depends entirely on which supply you measure. The buyback burns tokens and removes them for good, a process covered in the mechanics of the buyback and burn, while scheduled unlocks release tokens that were locked and add them to the pool people can trade. So is the supply shrinking or growing? On one basis PUMP looks "net deflationary", and on another it looks like the float is expanding, yet both numbers are true at the same time.
The two forces, side by side
The burn is straightforward: pump.fun uses about half of its revenue to buy PUMP on the open market and destroy it, which permanently retires those tokens and pushes supply down (source: pump.fun).
The unlocks work the other way, because a large part of the supply was locked at launch and is released on a multi-year schedule, set out in the full release schedule. When a batch unlocks, those tokens can move for the first time, so the amount available to trade goes up: one force subtracts and the other adds.
Basis one: on-chain supply is falling
The total minted supply, the number recorded on the Solana blockchain, is about 835 billion PUMP against a maximum of one trillion. That means roughly 165 billion PUMP, about 16 percent of the original mint, has already been bought back and burned, and this figure only goes down because burning is permanent while the mint stays capped at one trillion.
On this basis PUMP is deflationary: the on-chain supply is smaller today than it was last month, and it will be smaller again next month.
Basis two: the trading float is rising
Circulating supply measures a different thing, the tokens actually free to trade, so trackers strip out coins they judge to be locked or project-held. On this basis PUMP has been going the other way, with circulating supply climbing in recent weeks from around 390 billion to about 415 billion (source: CoinGecko).
The float moves in the opposite direction because unlocks are adding tokens to it faster than the burn is removing them. About 57 percent of the supply was still on vesting at launch, part of the full supply breakdown and who holds it, and that locked amount is released over time on a schedule reconstructed by third-party trackers (source: DropsTab). Each release moves tokens out of the locked bucket and into the freely trading pool, so the trading float grows even while the total minted supply shrinks.
Why two true numbers point opposite ways
Both statements are correct, since total minted supply is falling while circulating supply is rising, and they describe different things, so they can disagree while each stays accurate. When a source says PUMP is "net deflationary", the first question to ask is which supply it means, and over what window.
The window matters as much as the basis, so avoid turning this into a smooth daily rate, because unlocks arrive in uneven lumps that sometimes sit months apart. Over one short window the burn can outpace the tokens that unlocked, so the numbers look deflationary, then a large batch unlocks and over a longer window the float has still grown. Pick a different window and you can get a different sign.
The buyback shrinks as the price rises
The buyback is measured in dollars, so the same daily spend retires fewer PUMP as the price climbs and more PUMP when the price falls. The burn is therefore a moving number of tokens per day, running inversely with the price, and that is another reason the burn-versus-release margin keeps shifting rather than holding at a rate you can quote once and trust forever.
In round numbers, imagine a fixed daily buyback budget: on a day when the price is low, that budget might retire 150 million tokens, and if the price then doubles, the very same budget retires only about 75 million. Nothing changed except the price, yet the number of tokens burned was cut in half, which is why last month's burn rate is a poor guide to this month's.

So is PUMP deflationary?
The only accurate answer is that it depends on which basis and which window you choose. On total minted supply it falls every day, while on circulating supply the float has been rising as unlocks land. Whether that net picture should move the price is a separate question that nobody can answer honestly, so the practical step is to always check which supply a source is quoting before you accept the word "deflationary".

Frequently asked questions
Is PUMP a deflationary token?
It depends on which supply you measure. The total minted supply on-chain is falling as tokens are bought back and burned, while the circulating, tradable float has been rising as scheduled unlocks release locked tokens faster than the burn removes them, so both are true at once.
How much PUMP has been burned?
About 165 billion PUMP, roughly 16 percent of the one-trillion original mint, has been bought back and burned so far, which is why the on-chain supply sits near 835 billion, short of a full trillion, and that burned amount only rises over time.
If tokens are being burned, why is circulating supply going up?
Because two different things happen at once: burning removes tokens from the total minted supply, while unlocks move previously locked tokens into the trading float, and for now the unlocks are releasing coins more quickly than the burn is retiring them, so circulating supply climbs.
Does a bigger buyback always burn more tokens?
A bigger dollar buyback does not always burn more tokens, because it is measured in dollars, so a fixed spend covers fewer coins once the price has risen, and the number of PUMP burned per day moves inversely with the price and behaves as a moving token rate.
Which number should I trust for supply?
Both, as long as you know which is which: use the on-chain minted supply to see the effect of the burn, and use circulating supply to see the tradable float, because problems only start when a source quotes one and calls it the other.
