OP Inflation Analysis · September 2026 · Supply growing, projected to keep growing
Optimism creates no new OP at all — the OP token's supply reading actually fell by a fifth of one coin across the last 90 days — and yet the Pressure Framework reads OP at +6.47% over the trailing 90 days and +3.63%over the next 90. Every point of that comes from a single mechanism: the 2022 investor, contributor and ecosystem allocations being released on the Optimism Collective's published calendar, which moved 147.9M OP from restricted into freely tradable. Sell pressure is 147.9M OP, buy pressure is 0 because the Superchain-revenue buyback settled nothing in the window, and the ceiling is a genesis-fixed 4,295.0M OP that has never been added to.
The verdict, in one paragraph
Against a circulating base of 2,288.0M OP, the framework books 147.9M OP of sell pressure and 0 of buy pressure over the trailing 90 days — a net of +6.47% — and projects +3.63%for the next 90 days on what remains of Optimism's published Year-5 unlock calendar. The inflation monitor reads +6.18% for the same window, a gap of 0.28 percentage points, which is inside the framework's 0.5pp tolerance and therefore ships with no warning chip. Two effects nearly cancel there: the monitor divides its change by the 90-day-old supply, which lifts it, while the framework counts 14.7M OPof late-August releases the project's own supply file has not published yet, which lifts the framework by more. The label for OP is a fixed-supply token whose float is still being handed out: Optimism cannot inflate OP without a governance vote, but it can keep releasing what it minted in 2022, and right now it does.
Sell pressure: where new OP comes from
It does not come from minting. The OP token is a predeploy on OP Mainnet, and its entire supply of 4,294,967,296 OP was created in one genesis event in 2022. Read at both ends of the window, the count of OP in existence was 4,294,963,292.4987497 at the start and 4,294,963,292.2994190 at the end — it fell, by 0.199331 OP. So Sell #1, protocol inflation, is 0. Optimism does not pay validators or stakers in new OP; the network is secured by Ethereum and funded by sequencer revenue. A mint function does still exist in the OP token and it still answers: calling it reverts with the contract's own message, “Ownable: caller is not the owner”, which proves a live, role-gated function rather than a dead stub. Optimism's MintManager permits governance to mint up to 2% of supply a year — a ceiling of 85.9M OP — and it has never been used. Its own timer, read live, unblocks that lever onOct 28 2026, inside the forward window; the rate governance has set for it is zero. Because that path is open, the row is watched rather than closed permanently.
The entire supply story is Sell #2, vesting unlocks, at 147.9M OP. Optimism has no on-chain vesting or escrow contract — every allocation wallet traced for this build is an ordinary externally-owned address, not code — so there is no lock balance to difference. The number comes from two readings instead. Optimism's own published circulating-supply file stood at 2,154.7M OP at the start of the window and 2,288.0M OP at the end, which is 133.2M OP; and because that file has not been rewritten since Aug 21 2026, it does not yet contain the 14.7M OP the contributor-and-investor distributor paid out on chain on Aug 28 2026 andAug 31 2026. Together, 147.9M OP. That distributor is worth naming precisely: its entire history is monthly batches to two fixed recipients, it went from 207.2M OP to 174.6M OP across the window, and its outflows close against that balance change with a residual of 0.08 OP. It is worth being precise about what an unlock is and is not: no OP is created by one, the coins were already counted inside the 4,295.0M ceiling, and a fixed ceiling does not protect a holder from it.
Sell #3, Foundation and unscheduled unlocks, is 0 for the trailing window, and that zero is proven rather than assumed: every identified Collective wallet was read at both window ends and the largest, holding 1,294.0M OP, did not move by a single unit. The one large movement, 142.0M OP on Aug 7 2026, went from one Collective safe to another safe opened a week earlier, and Optimism's published circulating figure did not move for it — both sides sit outside the float. Forward, the row is not zero: the Collective's own Year-5 budget plans 200M OP of ecosystem deployment and 10M OP from the governance fund across the year, which is 50.4M OP of the 83.1M OP projected for the next 90 days. Sell #4, long-term locked or bankruptcy, is 0 as well: OP has no bankruptcy estate, no trustee and no court-ordered distribution attached to it.
Buy pressure: where new OP goes
Nowhere, this window. Buy #1, programmatic buyback, is 0 — and this is the row most worth explaining, because the buyback is real. Optimism governance approved it on Jan 28 2026 with 84.4% in favour: half of net Superchain sequencer revenue is routed into open-market OP purchases across a twelve-month pilot that began in February 2026. Purchased OP is parked in the Optimism Collective treasury, not burned; the proposal deliberately left any future burn or staking use to a later vote. The receiving wallet held exactly 9,451,924.208178954 OPat both ends of the window, unchanged to the ninth decimal. Because a flat pair of boundary readings can also be a stale reading, the balance was closed against an independent surface: the wallet's complete transfer history is eight transfers on a single page, every one of them landing before the window opened — 1.57M OP on Mar 2 2026, 6.95M OP on Apr 1 2026 and 0.93M OPon May 1 2026 — and they sum to the measured balance with a residual of zero. The programme has settled nothing in the 128 days since, four monthly windows missed, while the Collective's own August update was still reporting February and March revenue. With Base having left the OP Stack in February 2026, the revenue behind those purchases is shrinking rather than growing.
Buy #2, protocol fee burn, is 0, and there is no fee burn on OP to be zero for: Optimism routes sequencer revenue to the Foundation to redistribute rather than destroying it. Both places where OP can disappear were read at both ends of the window anyway. The unspendable address rose from 19.727662088 OP to 19.727672572 OP, and the count of OP in existence fell by 0.199331 OP. The two surfaces disagree by four orders of magnitude, which is the finding rather than a problem: they are independent — a burn call cuts the supply count without touching any dead address, and a transfer to a dead address does the reverse — and both moved by amounts too small to register. Buy #3, Foundation buy, is 0: outside the buyback programme the Optimism Foundation bought no OP on the open market, and its wallets only moved coins between each other. Buy #4, new long-term lock, is 0 — OP has no staking contract that removes coins from the float, and no new lockup was announced or deployed.
Foundation and overhang
The overhang on OP is very large and only partly attributable. 2,007.0M OP — 47% of everything that exists — sits outside the tradable float. Of that, two Optimism Collective safes hold 1,294.0M OP and 318.5M OP, which is 80% of the bucket and the part that can be named with confidence; the first did not move by a single unit across the window. A third safe, opened on Jul 31 2026, received 142.0M OP from the second on Aug 7 2026 and still holds 134.0M OP. The buyback treasury holds a further 9.5M OP. The remaining roughly 394M OP of the excluded bucket could not be attributed to named wallets: a search over every holder above 5M OP returns several combinations that fit the total within a hundred coins, one of which requires an exchange hot wallet, so none of them is defensible. That reconstruction is reported as partial rather than dressed up as complete.
One governance item enlarges the discretionary end of this overhang. A vote that closed on Aug 19 2026 with about 62% approval moved 546.9M OP out of the user airdrop reserve into a newly created, Foundation-directed Strategic Ecosystem Fund for partnership deals and OP Mainnet incentives. No coins moved on chain — it relabels who directs them — but it converts a passive reserve into a spendable one with no release calendar. Every item here is read from the chain at each rebuild, and the trigger sentence applies to all of them: if any of these balances falls between refreshes, that outflow enters Sell #3 at the next refresh.
How OP compares to other fixed-supply layer-2 tokens
OP belongs to the class of governance tokens on Ethereum layer-2 networks whose entire supply was minted at genesis and distributed over several years — the same shape as Arbitrum's ARB or Starknet's STRK. None of these tokens inflates in the way a proof-of-stake layer-1 does. A Cosmos or Solana validator set is paid in newly issued coins, so those chains carry a real, mechanical issuance rate of anywhere from a fraction of a percent to double digits a year. Optimism issues nothing: its security comes from Ethereum, and its operating costs come from sequencer revenue. On the pure issuance axis, OP is stricter than almost every layer-1 in existence.
And yet OP reads +6.47% while a mature capped chain reads a fraction of a percent. That is the whole lesson of the comparison: a fixed ceiling constrains total supply, not tradable float, and those are different quantities that move independently. The honest peer for OP is not Bitcoin but a four-year token distribution still working through its schedule — which is exactly what Optimism is, with 47%of the supply still outside the float in year five. The difference from a classic investor vest is that Optimism's largest remaining pools are not on an investor calendar at all; they are ecosystem and Foundation-directed money, which means the release rate is a governance decision rather than a contract.
The other structural comparison is to exchange tokens that run quarterly buybacks and burns. Those offset issuance with a demand-linked removal that scales with usage, and their inflation readings can go genuinely negative. Optimism has the same shape of mechanism on paper — a buyback funded by real network revenue — but two things separate the mechanism from the outcome. It buys and parks rather than burning, so the coins stay inside the total; and at 9.5M OP bought in seven months against 147.9M OP released in three, it is one coin bought for roughly every forty released. That is the gap between a buyback existing and a buyback mattering.
What to watch in the next 90 days
First, the mint lock, which lifts on Oct 28 2026 inside this very window: the ceiling behind it is 85.9M OPa year and the rate governance has set is zero, so the thing to watch is a proposal to change that rate rather than the date itself. Second, the buyback wallet, which is the single thing that could flip this page's sign and is read at every rebuild: any movement off 9,451,924.208178954 OP shows up immediately, and a resumption covering the four missed months would be a meaningful buy row. Second, the remaining Year-5 calendar — 216.0M OP still scheduled to reach the float by Apr 30 2027, which is where the +3.63% forward reading comes from; a Foundation update revising that figure moves the projection directly. Fourth, the Strategic Ecosystem Fund created on Aug 19 2026: 546.9M OP that now has a spender rather than a schedule, and whose first deployment would be a genuine Sell #3 event. Fifth, the 118 wallets that received the 545.5M OP custody rotation on Jul 22 2026 — they are new, they are full, and where they send next is on no calendar. Sixth, Superchain sequencer revenue itself, which funds the buyback and which lost its largest contributor when Base left the OP Stack in February 2026.
Summary
The MrNasdog Pressure Framework reads OP at +6.47% over the trailing 90 days and +3.63% projected forward: supply growing, projected to keep growing. The structural mechanism is not inflation but distribution — Optimism minted 4,294,967,296 OP once in 2022, has created none since, burned none, and its supply count actually fell by a fifth of a coin over the window, while the published unlock calendar and the contributor distributor together moved 147.9M OP into the tradable float. The key risk is that the largest remaining pools are discretionary rather than scheduled: 2,007.0M OP sits outside the float, an Aug 19 2026 vote handed 546.9M of it to a Foundation-directed fund with no release calendar, and the buyback that could absorb any of it has settled nothing since May 1 2026. The ceiling is the one genuine comfort — a governance vote is needed to mint OP, not merely to stop minting it, and that vote has never been taken.
