Polkadot mints about 10.5M DOT over the next 90 days as staking rewards under a newly reduced 2.5% yearly issuance rate, while nothing burns or buys DOT back — no buyback, and every fee and treasury burn was switched off in March 2026. New supply has no offset, so the framework reads about +0.62% net. Our supply monitor reads +0.654% realized over the last 90 days; the gap of 0.03 percentage points is within tolerance, so no monitor-gap chip is needed. DOT is now capped at 2.1 billion and mildly inflationary.
The verdict, in one paragraph
For the 90-day window ending July 14 2026, the MrNasdog Pressure Framework reads DOT at about +0.62% net on the forward view, driven entirely by Polkadot's staking inflation with no buy-side offset of any kind. Our supply monitor reads the realized last-90-day change at +0.654%, against the framework's +0.62% read for the same window — a gap of about 0.03 percentage points, well within the half-point tolerance, so no monitor-gap chip ships. Both reads land on the same picture: Polkadot now issues DOT at roughly 2.5% a year, down from the old ~10%, after a March 2026 governance overhaul capped supply at 2.1 billion and cut gross issuance by 53.6%. DOT is mildly inflationary by continuous staking emission, with no burn or buyback to brake it.
Sell pressure: where new DOT comes from
Sell #1 — protocol inflation — is the whole story, at about 10.5M DOT over the next 90 days. Polkadot mints new DOT every block as staking rewards; on-chain inflation now reads about 2.5% a year, a sharp drop from the old roughly 10% emission. The cut came from OpenGov Referendum 1710, the "Capped & Stepped" supply schedule enacted in the March 12 2026 runtime upgrade, which cut gross issuance 53.6% at the March 14 2026 step, holds that level for two years, then reduces the remaining supply by 13.14% every two years — the "Pi schedule" — toward the hard 2.1 billion cap. New DOT is paid to validators and nominators as staking rewards, but all of it is newly issued, so it counts once, here.
Sell #2 — vesting unlocks — is zero: the 2020 genesis sale, the 2020 redenomination and every early-backer allocation finished vesting years ago, so Polkadot's total supply already equals its circulating supply and no cliff hits the market. Sell #3 — Foundation and unscheduled unlocks — is also zero as a flow; the on-chain Treasury holds about 33M DOT but has no scheduled deployment, and any spend needs a passing governance vote. Sell #4 — long-term locked or bankruptcy — is zero, because no bankruptcy estate or court distribution applies to DOT, and bonded DOT is merely subject to a 28-day unbonding period rather than a long-term lock.
Buy pressure: where new DOT goes
The buy ledger is empty, and after March 2026 that is more true than ever. Buy #1 — programmatic buyback — is zero: staking rewards are paid from new emission, not by purchasing DOT back from the market. Buy #2 — protocol fee burn — is also zero, and this is the big change: the new Dynamic Allocation Pool, live since March 12 2026, halted every burn. Transaction fees, coretime sales revenue and validator slashes that used to be destroyed now flow into a governance-controlled pool instead, and the old unspent-treasury burn was removed outright. Buy #3 — Foundation buy — and Buy #4 — new long-term lock — are both zero, with no discretionary open-market buying or new escrow announced in the window. With no offset at all, every minted DOT is net new supply.
Foundation and overhang
DOT has no classic unlock overhang — the token is fully distributed, with total supply equal to circulating supply. The balances worth naming are the on-chain Treasury, holding about 33M DOT and now funded through the Dynamic Allocation Pool, and the Web3 Foundation reserve. Neither is a stockpile scheduled to dump: Treasury spending is gated by OpenGov referenda, and Foundation deployments are discretionary and infrequent. The framework books no discretionary release beyond protocol inflation and re-checks the on-chain issuance rate, total supply and Treasury balance on a roughly bi-weekly walk; if the Treasury balance falls between refreshes, that outflow enters Sell #3 at the next refresh.
How DOT compares to other uncapped proof-of-stake chains
Until 2026, DOT belonged squarely to the class of uncapped proof-of-stake L1s with continuous staking emission — the same family as Cosmos Hub — where there is no hard cap, just a dynamic inflation band that mints rewards to keep the chain secured. The March 2026 overhaul moved DOT out of that box: it now carries a hard 2.1 billion supply cap and a stepped, disinflationary issuance curve, which makes it look more like a capped asset approaching a ceiling than an open-ended emitter. At roughly 2.5% a year, DOT's issuance now sits below high-emission peers still running near 10%, and well below its own former rate.
The contrast worth drawing is with fee-burning chains that can flip net-deflationary at high activity. DOT does not: since the Dynamic Allocation Pool switched off coretime and fee burns, Polkadot destroys nothing under current rules, so it cannot go deflationary no matter how busy the chain gets — the cap only bounds the top, it does not remove supply already issued. For an inflation lens specifically, that means DOT reads as mildly, steadily inflationary — the staking emission is the only force on the page, and it points in one direction, just far more gently than before. The next scheduled easing is the March 2028 Pi step, which would cut issuance again.
What to watch in the next 90 days
Watch the on-chain issuance rate itself, the single number that decides Sell #1 — it should hold near 2.5% until the next Pi step in March 2028. Watch any OpenGov referendum that would re-enable a burn: the Dynamic Allocation Pool routes coretime and fee revenue to governance, so a future vote could send some of it to a burn and add the first buy-side row in DOT's current model. Watch coretime demand, since rising usage is the lever most likely to pressure governance toward burning revenue again. And watch the Treasury balance of about 33M DOT, the only governance-controlled stockpile that could reach the market through a spend vote.
Summary
DOT is a proof-of-stake staking token whose supply now grows by continuous emission at roughly 2.5% a year — down from the old ~10% after a March 2026 governance overhaul that capped supply at 2.1 billion and cut gross issuance 53.6%. Polkadot mints about 10.5M DOT over the next 90 days, while no buyback and no burn remove any — the fee, coretime and treasury burns were all switched off when the Dynamic Allocation Pool went live — leaving the framework at about +0.62% net. Our supply monitor reads +0.654% realized, a gap of about 0.03 points, so the framework and the monitor agree and no chip is flagged. DOT stays mildly inflationary with no offset — the key thing to watch is whether governance ever routes Dynamic Allocation Pool revenue back into a burn.
