Optimism mints no OP — its only supply growth is vesting, and that schedule ends around Jun 28 2026 with a final ~31M OP unlock. On the other side, a new program buys OP with 50% of Superchain sequencer revenue (~17M / 90 days), held in the treasury. Net next-90-day reading: about +0.65%, heading toward flat as vesting finishes.
The verdict, in one paragraph
For the trailing 90-day window ending June 14 2026, the MrNasdog Pressure Framework reads OP at +1.53% net, and the inflation monitor reads +1.67% — a gap of 0.14 percentage points, so no data-conflict chip is raised. Looking forward, the picture cools sharply: vesting ends around Jun 28 2026, the final ~31M unlock lands ~Jun 30, and the sequencer-revenue buyback (~17M / 90 days) offsets most of it, leaving a next-90-day net of about +0.65%. OP is a supply approaching structural flatness as scheduled emission runs out and a demand-linked buyback comes online.
Sell pressure: where new OP comes from
Sell #1 — protocol inflation — is zero. OP is the governance token of a Layer 2; there is no staking emission and no protocol mint. New OP has only ever entered through vesting.
Sell #2 — vesting unlocks — is the live flow, and it is nearly spent. The token-vesting schedule ends around Jun 28 2026; a final ~31M OP unlock (~1.4% of circulating) lands ~Jun 30, after which scheduled vesting is complete and this row falls toward zero. Sell #3 — Foundation and unscheduled unlocks — is zero as a flow: Retroactive Public Goods Funding (20% of supply), the unallocated Ecosystem Fund (8.8%) and the Partner/Seed/Governance funds are tracked overhangs, most completing vesting by Jun 28 2026, with no discretionary release booked. Sell #4 — long-term locked or bankruptcy — is zero; there is no bankruptcy estate.
Buy pressure: where new OP goes
Buy #1 — programmatic buyback — is now live and material. A January 2026 governance vote directs 50% of net Superchain sequencer revenue to monthly OP buybacks (started February 2026), running at roughly 17M OP over 90 days at recent prices. The bought OP goes to the Collective treasury — held, not burned — so it leaves the tradable market but could be redeployed later by governance; conversions pause if monthly revenue falls below $200K. Buy #2 — protocol fee burn — is zero; L2 transaction fees are paid in ETH to cover L1 data costs, not in a burned OP. Buy #3 — Foundation buy — is zero; the sequencer-revenue buyback is the accumulation mechanism. Buy #4 — new long-term lock — is zero.
Foundation and overhang
OP's overhang is the set of allocations that have been vesting since the 2022 genesis: Retroactive Public Goods Funding (20%), the unallocated Ecosystem Fund (8.8%), and the Partner, Seed and Governance funds. The defining fact in June 2026 is that the scheduled vesting for these completes around Jun 28 — so the overhang stops growing the circulating float on a fixed timetable. The framework books no discretionary release beyond the final scheduled unlock. The buyback treasury is a new, opposite-direction pool: OP bought with sequencer revenue accumulates there and is monitored, since governance could later burn it, redistribute it as rewards, or hold it.
How OP compares to other Layer 2 governance tokens
OP belongs to the class of Layer 2 governance tokens, alongside names like Arbitrum's ARB — tokens with no protocol emission whose supply is driven entirely by a multi-year vesting schedule. What distinguishes OP in mid-2026 is timing plus mechanism: its vesting schedule is essentially complete, and it has added a revenue-linked buyback, which most L2 tokens lack. That combination flips an L2 token from "steady unlock-driven dilution" toward "flat-to-deflationary," depending on how sequencer revenue and price move.
The mechanism nuance worth flagging is buyback-and-hold versus buyback-and-burn. OP's bought tokens go to the treasury, not a burn address, so the immediate effect is removal from the tradable float rather than a permanent supply cut. If governance later votes to burn the accumulated OP, the buy side becomes structurally deflationary; until then it is a treasury accumulation that could re-enter circulation. That is a softer form of absorption than a hard fee burn, and the framework tracks the destination accordingly.
What to watch in the next 90 days
The clearest event is the final vesting unlock around Jun 30 2026 (~31M OP) — after it, scheduled vesting is done and Sell #2 should fall to near zero. Watch Superchain sequencer revenue, which sets the buyback size (the program scales with revenue and pauses below $200K/month). Watch any governance decision on the accumulated treasury OP — a burn vote would turn the buy side structurally deflationary. And watch for any new emission or incentive program, which would reopen the sell side that vesting is about to close.
Summary
OP is a Layer 2 token whose supply is approaching structural flatness. There is no protocol emission; vesting — its only sell flow — ends around Jun 28 2026 with a final ~31M unlock, while a new buyback spends 50% of Superchain sequencer revenue on OP (~17M / 90 days) into the treasury. The trailing 90 days read +1.53% against the monitor's +1.67% (0.14pp apart, no chip), and the forward reading cools to about +0.65%. The key variables are whether sequencer revenue sustains the buyback and whether governance eventually burns the accumulated OP — the difference between flat and deflationary.
