Pump.fun spends half of its revenue destroying its own token, and PUMP still put +9.78% of supply onto the market in 90 days. The reason is a calendar, not a printer: the PUMP mint on Solana has an empty mint authority, so nothing can be created, but the 12-month lock on the Pump.fun team and investor allocations expired in Jul 2026 and 64.2B PUMP of already-minted supply reached the float — 57.279B on Jul 15 2026 and 6.875B on Aug 12 2026 — against 25.8B PUMP bought on the open market and burned. Our supply monitor reads the same window at +10.26%, a gap of 0.47 percentage points, inside tolerance. Forward, the Pressure Framework reads PUMP at −1.31%: the one-off vesting cliff is behind it, and the buyback-and-burn is now larger than the monthly unlock.
The verdict, in one paragraph
For the 90-day window ending Aug 14 2026, the Pressure Framework reads PUMP at +9.78% net. Sell pressure totals 64.2B PUMP, all of it vesting unlocks; buy pressure totals 25.8B PUMP, all of it the revenue-funded buyback-and-burn; the circulating base is 392.4B PUMP. Our supply monitor reads the same window at +10.26%, a gap of 0.47 percentage points — under the half-point tolerance, so no data-conflict chip ships on the PUMP overview page. The residual is a base convention rather than a disagreement about events: the same net rise divided by the May float reads slightly higher than the same rise divided by today's float. Forward the number inverts to −1.31%, because the July cliff was a one-time release and what remains is a steady 6.875B a month against a burn currently running near 0.29B PUMP a day. PUMP is best characterised as a hard-capped token deflating its ceiling while its float finishes unlocking.
Sell pressure: where new PUMP comes from
Sell #1, protocol inflation, is zero in the strongest available form. The PUMP mint account on Solana was read directly this session: the mint authority field is empty and so is the freeze authority, so no party — not Pump.fun, not a governance vote, not a future upgrade — can create a single new PUMP, and there is no block reward, staking emission or rebase attached to the token. The cap is a fixed 1 trillion PUMP; what actually exists today is 840.7B, because roughly 159.3B has already been destroyed by the buyback contract. PUMP's ceiling is a one-way ratchet downward.
Sell #2, vesting unlocks, carries the entire sell side at 64.2B PUMP. The Pump.fun cap table allocates 20% (200B PUMP) to the team and 13% (130B PUMP) to existing investors, both behind a 12-month cliff from the Jul 2025 ICO followed by three years of linear release. The published calendar allowed roughly 82.5B PUMP at the cliff. What actually left the vesting contract on Jul 15 2026 was 57.279B PUMP, distributed across 121 wallets, with a single address taking 52.039B and a second taking 5.24B. The framework books the released figure, not the scheduled one — coins that vested on paper but never left the contract are not sell pressure yet. The second component is the first monthly linear tranche, 6.875B PUMP released on Aug 12 2026 and split 4.17B to the team and 2.71B to investors, which is exactly 330B divided by 48 months.
Sell #3, Foundation and unscheduled unlocks, is zero: no dated, sized discretionary release was observed inside the window. Sell #4, long-term locked or bankruptcy, is zero and structurally so — Pump.fun is a going concern with a treasury reported at $855M in stablecoins and $211M in SOL, so there is no estate, trustee or court-ordered creditor distribution that could release PUMP.
Buy pressure: where new PUMP goes
Buy #1, the programmatic buyback, is the whole buy side at 25.8B PUMP. Since Apr 28 2026 an irreversible one-year smart contract routes 50% of Pump.fun's net revenue — bonding curve, PumpSwap venue and terminal — into open-market PUMP purchases, and every coin bought is burned on arrival. That last detail is what makes it count fully: there is no accumulation wallet holding bought-back PUMP that could quietly return to the market, and the destination is verifiable because the on-chain supply of the PUMP mint falls with each burn. Over this window the programme spent $45.0M and destroyed 25.8B PUMP, roughly 0.29B a day. It replaced an earlier design that bought with 100% of revenue and merely held; that stockpile was itself burned in two transactions on Apr 29 2026, destroying 127.25B PUMP at once — before this window, so it is not booked here.
Buy #2, protocol fee burn, is zero as a bookkeeping decision rather than an absence: PUMP has no automatic burn inside the token contract, the only destruction route is the revenue-funded buyback above, and booking the same burn twice would double the buy side. Buy #3, Foundation buy, is zero — no Pump.fun entity disclosed a dated, sized open-market PUMP purchase for its own book, and the corporate treasury is held in stablecoins and SOL rather than in the token. Buy #4, new long-term lock, is zero: no lockup contract was deployed inside the window and PUMP has no staking that removes coins from the float.
Foundation and overhang
Outside the counted float sit 448.3B PUMP, and four pools inside it are tracked as team-controlled overhang. The largest is the community and ecosystem allocation, 24% of the cap or roughly 240B PUMP, with no published dated calendar; the ecosystem fund at 2.4% (~24B PUMP), the Pump.fun foundation at 2% (~20B PUMP) and the liquidity and exchange reserve at 2.6% (~26B PUMP) share that status. The fourth is the most specific: when the Jul 2026 cliff paid out 57.279B against a scheduled 82.5B, roughly 25.2B PUMP stayed undrawn inside the insider vesting contract, and that backlog can be claimed at any time without appearing on the monthly calendar. All four are refreshed by chain read plus a bi-weekly walk of project disclosures; the buyback needs no overhang line, because bought-back PUMP is destroyed rather than held. If any of these balances falls between refreshes, the outflow enters Sell #3 at the next refresh.
How PUMP compares to other revenue-buyback tokens
Against the class of exchange and launchpad tokens that spend revenue on their own supply, PUMP sits at the aggressive end on mechanism and at the awkward end on timing. The classic quarterly-buyback exchange token commits a share of profit, executes on a schedule the company controls, and in several cases holds rather than burns — which leaves a treasury balance that is float-neutral until it moves. PUMP's contract is stricter on all three counts: the rate is fixed at 50% of net revenue, execution is continuous rather than quarterly, and the destination is a burn that cannot be reversed, locked in for a year to Apr 2027. Measured against supply, that is a large programme — 159.3B PUMP, close to 16% of the 1T cap, has already been destroyed.
The contrast with a fee-burn L1 is about what funds the burn. An EIP-1559-style chain burns a share of every transaction fee, so the burn scales with usage and continues regardless of whether the issuer is profitable. Pump.fun's burn is paid out of company revenue, which makes it larger while the launchpad is busy and smaller when it is quiet: the week of Aug 3–9 2026 generated $10.03M in protocol fees, a record, and put $5.02M of it into burning 2.15B PUMP. Where PUMP differs from both classes is age. A hard-capped chain has no cap table and a mature exchange token finished vesting years ago; PUMP began its insider release only in Jul 2026 and still has 265.8B PUMP of team and investor supply scheduled to 2029 at 6.875B a month. That is why the trailing window reads +9.78% and the forward window reads −1.31%.
What to watch in the next 90 days
First, three dated vesting tranches of 6.875B PUMP each land on Sep 12 2026, Oct 12 2026 and Nov 12 2026; together they are the entire forward sell side at 20.6B PUMP. Second, whether the 25.2B PUMP left undrawn from the July cliff gets claimed — that backlog is off-calendar and would enter Sell #3 the moment it moves. Third, Pump.fun's weekly protocol fee run-rate: the burn is 50% of it, so a sustained fall from the current record would shrink the buy side and flip the forward reading back toward growth. Fourth, the Apr 2027 expiry of the one-year buyback contract, which is outside this window but is the single largest structural risk to the buy row. Fifth, any dated release from the community and ecosystem allocation, still the biggest unscheduled pool at roughly 240B PUMP.
Summary
PUMP cannot inflate: the mint authority on its Solana mint is empty, the cap is a fixed 1 trillion, and 159.3B PUMP has already been destroyed, leaving 840.7B in existence. Its supply pressure comes entirely from a cap table finishing its first year of release — 64.2B PUMP reached the float over the 90 days to Aug 14 2026, against 25.8B PUMP bought and burned with half of Pump.fun's revenue, for a Pressure Framework reading of +9.78% versus a monitor at +10.26%. The key risk is that the burn is funded by trading revenue rather than by protocol fees, and the contract behind it expires in Apr 2027; the key support is that the monthly schedule of 6.875B PUMP is now smaller than the burn, which is why the next 90 days read −1.31%.
