Pump.fun burns roughly 17B PUMP over the next 90 days, funded by half its platform revenue, and no scheduled unlock lands inside the window — the last big cliff, about 19.17B PUMP to early investors, already released on Jul 12 2026. So the framework reads PUMP at about −4.2% net on the forward view — a quiet, deflationary window. The prior 90 days shrank far harder, about −30.8%, on the Apr 29 2026 mega-burn; our supply monitor reads that window at −31.95%. PUMP is a fixed-cap Solana launchpad token that swings between deep deflation and sharp inflation depending on whether a burn or an unlock dominates the quarter.
The verdict, in one paragraph
For the 90-day window opening Jul 14 2026, the MrNasdog Pressure Framework reads PUMP at about −4.2% net — deflationary. PUMP is the token of the Solana launchpad pump.fun; it has a fixed one-trillion supply cap and no protocol inflation, so the only forces on supply are scheduled vesting unlocks and a fee-funded buyback-burn. This window the buyback removes roughly 17B PUMP and no cliff unlocks against it, so the float falls. Our supply monitor reads the trailing 90 days at −31.95% — a much larger shrink than our own −30.8% book of that same past window, a gap of about 1.1 percentage points that ships a ⚠ monitor-gap chip. That gap is base convention plus a small excess in the monitor's price-derived supply drop over the confirmed on-chain burns; the flows themselves — the Apr 29 burn and the Jul 12 cliff — are primary. PUMP is by design a swing token, and this quarter the quiet side wins.
Sell pressure: where new PUMP comes from
Sell #1 — protocol inflation — is zero. PUMP is capped at one trillion and has no staking or block mint, so the protocol never creates new coins on its own. Every coin that will ever exist already exists; supply only moves as locked allocations vest into the float, or shrinks as the buyback burns.
Sell #2 — vesting unlocks — is zero inside this window, and that is the pivotal fact of the forward read. PUMP vests on a cliff schedule, not a smooth monthly drip, and the last cliff — about 19.17B PUMP, roughly 1.9% of total supply, to the early-investor bucket — released on Jul 12 2026, two days before this window opened. It therefore sits in the prior 90 days, not ahead. No scheduled unlock falls between Jul 14 and Oct 12 2026; the next material cliff is beyond the window, with the remaining locked buckets vesting through 2029. Sell #3 — Foundation and unscheduled unlocks — is zero, with no discretionary release pending outside that vesting calendar. Sell #4 — long-term locked or bankruptcy — is zero; no estate or court distribution applies to PUMP.
Buy pressure: where new PUMP goes
Buy #1 — programmatic buyback — is the entire buy side and the only active force this window, at about 17B PUMP over the next 90 days. Since late April 2026, half of all net revenue from the bonding curve, PumpSwap and the Terminal is automatically used to buy PUMP on the open market and burn it — the coins are destroyed, not held — locked into an irreversible one-year contract that runs without team discretion. Platform revenue has fallen sharply through 2026, running near $18M a month recently against a far higher 2025 pace, so the current buyback works out to only about 17B coins over the window. The much larger burn is already behind it: on Apr 29 2026, pump.fun destroyed about 127.3B PUMP in one event — 123.1B plus 4.15B tokens, the prior nine months of accumulated buybacks, worth roughly $370M and about 36% of circulating supply — which is why the last-90-day burns total near 142.9B. Buy #2 — protocol fee burn — is zero as a separate line: there is no base-fee burn, the revenue buyback is the only burn, and it is already counted in Buy #1. Buy #3 — Foundation buy — and Buy #4 — new long-term lock — are both zero, with no discretionary buying or new escrow announced.
Foundation and overhang
PUMP's overhang is unusually concentrated. About 448B PUMP — more than the entire circulating float — is still locked, split across the team (about 20% of total supply), community and ecosystem (about 24%), early investors (about 13%, now lighter after the Jul 12 cliff), and a foundation and ecosystem fund near 4% combined. These are team-and-insider allocations that release on a fixed vesting calendar rather than at will, so the framework does not book them as discretionary sell pressure — but it does watch them, and the Jul 12 2026 cliff was the most recent time a large slice moved from fully locked into the float. The bought-back PUMP does not add to this overhang: it is burned, permanently destroyed on-chain, not parked in a treasury that could later sell. If any locked balance falls between refreshes ahead of its scheduled unlock, the outflow enters Sell #3 at the next refresh. For now the buyback-burn is the only supply force in motion, and with no cliff against it the window reads cleanly deflationary.
How PUMP compares to other capped, buyback-burn tokens
PUMP belongs to the class of fixed-cap tokens with a revenue-funded buyback-burn — closer to an exchange token than to an inflation chain. Unlike an uncapped proof-of-stake coin, PUMP can never mint; unlike a passive fixed-supply token, it actively destroys coins out of revenue. What makes PUMP unusual is the size and timing of its unlocks: most buyback-burn tokens fight a slow, steady emission, but PUMP fights a small number of very large cliffs. The result is a token that whipsaws between deflation and inflation depending on which side fires that quarter — and because the buyback burns rather than accumulates, the deflation it produces is real and permanent, not a treasury overhang waiting to reverse.
The contrast worth drawing is with a token that burns continuously and unlocks continuously — there, the two forces roughly net out month to month. PUMP does not have that smoothness. Its buyback-burn is continuous but modest, and its unlocks are lumpy and huge, so any single 90-day read is dominated by whether a cliff lands inside it. For an inflation lens, that means PUMP's headline can swing from about −30.8% to about −4.2% in back-to-back windows with nothing wrong in the math — one window held a record burn and a cliff, the next holds only the quiet ongoing burn.
What to watch in the next 90 days
Watch platform revenue first, because the buyback-burn is fixed at 50% of it — a stronger launchpad quarter means a bigger burn and a deeper deflation, and the recent revenue slide cuts the other way, shrinking the only active force on supply. Watch that the one-year burn contract keeps running to its term without being unwound. Watch for the next vesting cliff beyond the window: the moment a dated unlock enters the forward 90 days, Sell #2 turns on and the read can flip inflationary again, exactly as the Jul 12 2026 cliff did in the prior window. And watch whether any of the locked team, community or investor buckets moves ahead of schedule, which would surface as discretionary Sell #3 pressure the framework is not currently booking.
Summary
PUMP is a fixed-cap Solana launchpad token with no protocol inflation, a revenue-funded buyback-burn, and a few very large unlock cliffs. Over the next 90 days the buyback removes about 17B coins and no cliff unlocks against it, leaving the framework at roughly −4.2% net — a quiet, deflationary window. That is a calmer echo of the prior 90 days, when the Apr 29 2026 mega-burn of about 127.3B PUMP, net of the Jul 12 investor cliff, cut supply by about 30.8%, a shrink our supply monitor reads slightly deeper at −31.95%. PUMP swings between deep deflation and sharp inflation depending on which side fires, and this window there is no cliff — only the burn.
