Supply Overhang
Supply overhang is the stock of tokens still to come, both locked on a published schedule and locked with no date attached, measured against today's circulating supply. It is the anticipatory weight the market carries before anything is released, as distinct from the selling that happens when tokens actually land.
TradFi parallel: Like the block of restricted shares an IPO leaves hanging over a stock: SpaceX's listing left roughly 95% of shares locked on a staggered schedule. The analogy stops short, since a lockup covers shares that already exist and token overhang counts supply that does not yet.
Key Takeaways
- 01Overhang is locked supply measured against today's circulating supply, so the ratio matters far more than the raw token count
- 02It merges dated locked supply with TBD supply that has no published release date, which a schedule-only view leaves out entirely
- 03It is cumulative: the weight comes from the aggregate of everything still to come, not from the next date on the calendar
- 04Overhang is the anticipatory weight on price, while supply pressure is the realised selling once tokens are circulating and sold
- 05Only a burn removes tokens permanently: a release converts overhang into float, a buyback retires nothing unless the tokens are burned or locked, and extensions only move the date
How It Works
Overhang is a ratio, not a token count. What matters is locked supply measured against the float it will eventually join, because the same absolute number is trivial against a large circulating base and existential against a small one. Pump.fun is the clean case: roughly 487.5B PUMP, about 120% of today's circulating supply, sits locked or unscheduled behind its first insider cliff. LayerZero's ZRO has run a similar profile, with around 150% of circulating supply scheduled for release over a twelve month window and the majority of it going to insider cohorts. In both cases the market can size the claim on future float long before a single token moves.
What separates overhang from a straight schedule reading is that it deliberately merges two categories the calendar keeps apart. Dated locked supply has a release date you can plot. TBD locked supply has none: Pump.fun's 240B community bucket carries a TBD allocation type with no published date or mechanics, flagged since July 2025 and still undelivered, which the research treats as a distinct overhang from the dated insider lock. A model that counts only what is dated understates the claim on future supply, because undated tokens do not stop existing. They simply refuse to appear on the calendar.
Overhang is also cumulative rather than event driven. Sui's structural overhang comes from the aggregate of monthly releases running through 2030 rather than from any single date on the calendar, which is why reading the next unlock in isolation misses the weight. That is the line between overhang and supply pressure: supply pressure is the realised downward force once tokens enter circulation and are sold, while overhang is what the market prices in advance of that, and it is at its heaviest precisely when nothing has been released yet.
Only a few things actually move overhang. A release converts it into float, clearing the overhang and creating supply pressure in the same moment. A burn removes tokens permanently, while a buyback takes them off the market but only retires them if the tokens are burned or credibly locked, because treasury holdings can be redeployed. Either way the offset has to be large enough to matter: Pump.fun's burn runs at a shrinking 101B a year against that 487.5B. Everything else reschedules rather than removes. Huma Finance's team and major investors voluntarily extended their May 26 investor cliff by six months to November 26, and Hyperliquid recipients have repeatedly claimed a fraction of what the schedule permits, cutting one $675M scheduled release to a $38M claim. Both reduce what reaches the market in the near term. Neither reduces the token count still waiting behind the lock.
Real World Examples
Pump.fun: 120% of the float still locked or unscheduled
View →Roughly 487.5B PUMP, about 120% of today's circulating supply, remains locked or unscheduled behind the July 2026 insider cliff. The token has no emission and a fixed 1T cap, so none of this is new issuance. It is existing supply waiting to move from locked to available, and the burn offsets only a shrinking 101B a year against it.
LayerZero: a release schedule larger than the float
View →ZRO was set to release around 150% of its circulating supply over a twelve month window, with the majority allocated to private investors and core team members. Because the distribution flow originates with early stakeholders rather than community incentives, the research reads it as a structural overhang the market has to absorb rather than a single dated event.
Sui: the weight is in the aggregate, not the date
View →With vesting extending through 2030 and roughly 40% of total supply released to date, Sui's overhang comes from the sum of its monthly releases rather than from any one entry on the calendar. Reading only the next unlock, which is often modest in isolation, understates a claim on future float that accumulates month after month.
Hyperliquid: restraint shrinks the release, not the lock
View →One $675M scheduled release was cut to a $38M claim after the recipients committed to leaving the bulk unclaimed, taking the effective release from 2.54% of circulating supply to roughly 0.14%. That turns a major near-term event into a modest one, but the unclaimed tokens stay behind the lock and remain part of the overhang.
SpaceX: the same structure in equities
An IPO that floated under 5% of the shares left roughly 95% of them locked, a staggered overhang against a very small free float. The mechanics mirror the cliff-and-vest structures crypto investors track weekly, and equity markets have long priced that overhang into the stock well before any lockup expires. The parallel is not clean, though: a lockup covers restricted shares that already exist, while token overhang also counts supply that has not been minted or allocated yet.
Frequently Asked Questions
How is supply overhang different from supply pressure?
Overhang is the stock of supply still to come and the weight the market attaches to it in advance. Supply pressure is the flow: the realised downward force once tokens are in circulation and being sold. A token can carry a heavy overhang for years with nothing released, and a token can face acute supply pressure from a release that barely dents its remaining overhang. Overhang tells you the size of the claim on future float; supply pressure tells you what a specific release does to the order book.
Why count tokens that have no unlock date?
Because they still exist and still have a claim on future float. Pump.fun's 240B community bucket carries a TBD allocation type with no published release date or mechanics, which the research treats as a distinct overhang alongside the dated insider lock. Excluding undated tokens produces a comfortable number that is wrong in one direction only. On Tokenomist, TBD locked supply is labelled separately from dated locked supply, so you can see how much of the overhang has no calendar entry at all.
Does a large overhang mean the price will fall?
No. It quantifies how much supply demand will eventually have to absorb, not the outcome. Tokens with strong demand catalysts have absorbed large releases without a decline, and the reverse also happens: TRUMP fell more than 80% from its peak before any major unlock occurred, repricing without the supply event at all. Overhang is a risk measure that sets the size of the problem. Liquidity, demand and positioning decide how it resolves.
How do I measure a token's overhang on Tokenomist?
Start from the gap between market cap and FDV, which is the market's priced version of the overhang, then decompose it on the Emission Screener and the Allocation Screener: how much locked supply is dated, how much is TBD, which beneficiary categories hold it, and what all of that equals as a percentage of current circulating supply. The percentage against float, not the dollar figure, is what makes two tokens comparable.
Can a project reduce its overhang?
Only a burn removes tokens permanently. A release converts overhang into float rather than retiring it, and a buyback takes tokens off the market but only retires them if they are burned or credibly locked, since treasury holdings can be redeployed. Everything else reschedules it. Voluntary lockup extensions, like Huma Finance's six month extension of its investor cliff, and voluntary restraint on claiming push the timing out and are read as alignment signals, but the token count behind the lock is unchanged. Treat those moves as a change in timing and intent, not as a reduction in eventual dilution.
