In the stock market, knowing in advance that an avalanche of shares is about to flood the market would be considered insider information and would land whoever used it in court. In crypto, that same information is published for free on a website, with the exact date and time—and yet retail investors still buy in right before and take the hit. A token unlock is the scheduled release of a portion of the supply that was contractually restricted: coins reserved for the team, early investors, and the project treasury that could not be sold from day one. The mechanism that holds them is called vesting (deferred delivery over time); the initial period where nothing is released is called the cliff; and the number the project wants you to look at—the circulating supply, coins already on the market—is almost always a fraction of the total yet to come. This guide teaches you how to read that calendar like a fund does: how to distinguish a linear trickle from a wall of supply, how to interpret an unlock website column by column, why market cap (capitalization by circulating supply) is misleading while FDV (fully diluted valuation, assuming all coins are in circulation) tells the truth, and why the price usually moves weeks before the event, not on the day itself. Market cap tells you what it's worth today; the unlock schedule tells you who is going to sell tomorrow. Only one of those is "insider" information—and it's the free one.

What are vesting and cliff, and why do they exist?

Think about how a tech company pays a key employee with stock options. They don't hand over the entire package on the first day: it is released over four years, and usually nothing is given in the first year. If they leave after six months, they walk away empty-handed; if they stay, they become the owner of a larger portion each month. This structure has a name in the crypto world identical to Silicon Valley: vesting, the deferred delivery of an asset in exchange for staying with the company or meeting a deadline.

A token is born the same way. At the Token Generation Event (TGE), the project sets how many coins will exist in total—the maximum supply—and divides that total into buckets: one for the public, one for the founding team, one for seed investors, and another for the treasury to fund the ecosystem. Only the public bucket circulates from the start. The others are frozen by smart contract (self-executing programmed contracts) and are released according to a pre-written schedule.

The initial period in which these buckets release nothing is the cliff. The name is literal: for months, the available supply does not move, and when the cliff date arrives, an entire tranche drops at once. The specific day one of those frozen portions becomes transferable—sellable—is the token unlock.

Why does all this exist? To align incentives. If the team could sell on day one, they would have no reason to build anything afterward: they would cash out and leave. Vesting ties their net worth to the project for years. The problem—and here begins the thesis of this guide—is that the same calendar that protects the project is a public map of when new supply will appear that someone will want to sell. The lockup following an IPO works with this same logic: we analyze it in detail in how the SpaceX IPO lockup replicates crypto vesting mechanics.

Linear vesting, cliff, or milestones: why the shape matters as much as the date?

Two tokens can release the exact same number of coins and have an opposite impact on the price. What changes is not how much, but how. There are three basic forms, and the difference between them is pure arithmetic.

Imagine a project that must release 1 billion tokens reserved for its team. In linear vesting, that volume is distributed in a constant trickle: if distributed over 12 months, it's about 83 million per month, or about 2.7 million per day. The market absorbs that supply continuously and predictably; every day there is a little more, but never a jump. In a cliff, the same volume appears on a single date: 1 billion all at once. Compared to the daily linear trickle, that concentrates in an instant what the linear would have taken 365 days to release. The total supply is identical; the selling pressure per unit of time is hundreds of times higher. That's why a cliff easily sinks the price while a linear release is rarely noticed.

The third form is milestone vesting: coins are released not on a date but when a condition is met—trading volume, user count, or a sustained price. Its advantage is that supply only arrives when the project is performing; its problem is unpredictability: no one knows the exact day, so the market cannot price it in advance.

Unlock TypeSelling PressurePredictabilityReal Example
LinearLow and constant (daily or monthly trickle)High: fixed date and amountHYPE: up to ~9.92M per month on the 6th (calendar maximum; actual distribution has been lower)
CliffHigh and concentrated (all on one date)High: exact date knownPUMP: investor tranche on July 12, 2026, according to public calendar
MilestoneVariable, linked to performanceLow: depends on meeting the conditionConditional tranches by price or usage (common in IPO lockups and some TGEs)

There is a nuance that almost no one looks at: a linear release can be neutralized if the project burns more coins than it releases. Hyperliquid (HYPE token) releases a monthly linear tranche to its contributors, but its buyback and burn mechanism removes tokens from the market in parallel; the net effect on supply is not the gross unlock figure. We expand on this interaction between release and burning in the analysis of Hyperliquid architecture (HyperCore and HyperEVM). The general lesson: always look at the net supply, not just the tranche being unlocked.

How to read an unlock calendar step-by-step?

There are free websites that compile the vesting schedules of hundreds of tokens by reading them directly from the contracts: the best known used to operate as TokenUnlocks and now does so as Tokenomist (token.unlocks.app), and there are alternatives on CoinGecko, DefiLlama, Cryptorank, or Coinglass. They all present more or less the same columns. Knowing how to read them is what separates those who buy blindly from those who know what's coming.

  • Unlock Date. The day the tranche becomes transferable. In a linear release, you will see a continuous trickle; in a cliff, an isolated spike on the chart. What matters is not just the date: it's how many days are left, because the price usually moves beforehand (see below).
  • Amount and % of Circulating Supply. The absolute number of tokens matters less than its relative size. An unlock of 50 million coins says nothing on its own; an unlock equivalent to 20% of the circulating supply is an alarm signal, because it means the supply available to sell suddenly grows by a fifth.
  • Who they go to. A tranche for the ecosystem treasury—which will likely be used for grants and not dumped on the market—is not the same as a tranche for seed investors who bought at a fraction of the current price and have been waiting two years to sell. The recipient predicts the probability of a sale.
  • Recipient's Entry Cost. An investor who entered at $0.01 and sees the token at $1 has a massive incentive to take profits as soon as they can. The greater the difference between their purchase price and the market price, the higher the expected selling pressure.
  • Committed Buyers. Sometimes a tranche goes to a strategic partner or an agreement with an additional lockup. That cushions the blow: the supply is contractually released but not sold.

A case for practice: the unlock of a large tranche of PUMP (pump.fun token) to investors is dated July 12, 2026, exactly one year after its initial sale, and releases to a bucket with an entry cost far below the market price—the maximum selling pressure profile. We cover the context of the project behind that token in the analysis of pump.fun revenue as an on-chain casino. Reading that calendar before buying is seeing the hit coming; ignoring it is being the one who takes it.

Why market cap is misleading: Circulating Supply vs. FDV

Here is the vanity metric that sustains almost all retail investor self-deception. Market cap is calculated by multiplying the price by the circulating supply: the coins already on the market. It is the figure that appears large on all websites, the one used for rankings, the one the project wants you to look at. And it is, systematically, the smaller half of the story.

The figure that tells the truth is FDV, fully diluted valuation: the price multiplied by the maximum supply, assuming all coins that will ever exist were already circulating. The gap between market cap and FDV is exactly the supply that is still locked waiting for its unlock.

A numerical example makes it clear. A token with a market cap of $100 million and an FDV of $2 billion has only 5% of its supply in circulation. The other 95%—$1.9 billion at today's price—is locked in vesting schedules and will hit the market in tranches. For the price to hold when that supply enters, the market would have to provide $1.9 billion in new demand just to absorb it without falling. That demand almost never appears. That's why a very low market cap/FDV ratio—say, below 0.2—is a red flag: it means most of the value has not yet hit the market and the current price rests on an artificially scarce supply.

MetricSupply-Scarce TokenMature Token
Market cap$100 M$1,600 M
FDV$2,000 M$2,000 M
Circulating Supply5%80%
Supply yet to unlock$1,900 M$400 M
Market cap / FDV Ratio0.050.80

Two tokens with the same FDV of $2 billion are not the same bet. The one on the left has almost all its value ahead of it in the form of supply that someone will sell; the one on the right has already gone through almost all its unlocks and its price reflects real supply. The risk of dilution from new supply is one of the least monitored structural risks of spot investing, and we address it in the general framework of how to understand risk in crypto and alongside other metrics in the DeFi metrics guide (TVL, APR, APY), which covers performance indicators but not FDV.

How does price react before and after an unlock?

Retail intuition is usually: the unlock is on day X, so the price will fall on day X. It is exactly the opposite. Since the calendar is public, participants who know how to read it don't wait for the event: they position themselves beforehand. The result is an empirical pattern—a trend observed in many cases, not a law—that should be formulated cautiously: the market tends to price in the unlock in the preceding weeks, so that by the time the date arrives, much of the move has already occurred.

The causal mechanism is direct. Those who already own the token and anticipate new supply entering have an incentive to sell before that supply, not after. Short sellers open positions anticipating the pressure. And the unlock recipients themselves, if they can, hedge their exposure in advance. All this activity pushes the price down in the weeks prior, not on the day. When the event finally occurs, one of two things happens: if the selling is as expected, not much happens because it was already priced in; if the selling is less than feared—because part of the supply was not dumped on the market—there may be a relief bounce, the classic "sell the rumor, buy the news."

The practical consequence for the reader is twofold. First: buying right before a large cliff is buying against a known current. Second: the unlock date is not the moment of danger; the danger starts weeks before. None of this predicts the price—a project with real demand can absorb its unlock without flinching, and a bull market covers many unlocks—but ignoring the calendar is giving up the only informational advantage the crypto investor has for free. That's why vesting schedules are a top-tier risk in spot investing, as we argue in the guide to spot investing in a bear market.

How much new supply actually enters each month?

To size the phenomenon, it is useful to look at the aggregate, not a single token. According to public calendars compiled by Tokenomist as of June 21, 2026, scheduled unlocks for June 2026 totaled around $580 million spread across some 144 projects, with the bulk concentrated in a handful of large tokens. The danger is not in the total but in the relationship between each unlock and the size of the token emitting it: an unlock of tens of millions is noise for a large-cap token and an earthquake for a mid-cap one.

  • HYPE (Hyperliquid): monthly linear tranche to contributors on the 6th of each month, with a calendar maximum of ~9.92 million tokens (the whitepaper projects 238 million over 24 months, although actual distributions have been significantly lower), and the bulk of vesting completing toward late 2027 (24 months from the November 2025 TGE). An example of how a large linear release in absolute value is modest in relative dilution for a token of its size.
  • PUMP (pump.fun): investor tranche dated July 12, 2026, with around 41-42% of the supply still locked by then according to public calendars (a percentage that decreases with accumulated linear vesting). An example of a cliff with a fixed date on a low entry-cost bucket.
  • The rest of the monthly aggregate is made up of infrastructure and mid-cap tokens where a single unlock can equal a double-digit percentage of their circulating supply—the profile where the calendar carries the most weight.

The exercise that separates the informed investor from the rest is trivial to do and almost no one does it: before buying a token, open its unlock calendar, look at when the next large tranche is, who it goes to, and what percentage of the circulating supply it represents. Five minutes of reading public information. We follow the market context of these unlocks in the June 2026 crypto events and scenarios playbook.

Can vesting be slowed down or canceled?

Yes, and it's worth knowing because it breaks the idea that the calendar is immutable. Vesting lives in a smart contract, but who controls that contract varies. In some projects, the conditions are rigid and cannot be touched by anyone; in others, governance—the set of token holders who vote—can modify, delay, or even suspend a tranche.

The most discussed case was Jupiter (JUP token) on Solana, whose team decided to suspend their own team token vesting, removing supply from the calendar that the market expected—a signal of alignment with holders that the market read as positive. This is the context we cover in the analysis of Jupiter as the Solana superapp. The lesson is not that unlocks are canceled often—it rarely happens—but that the calendar you read today can change, and that a project that voluntarily cuts or freezes insider supply is sending a different signal than one that releases every tranche on the dot. It is worth checking the calendar periodically, not just once.

What does an informed investor look at before buying a token?

The retail investor who loses money on an unlock doesn't lose it due to a lack of information, but by looking at the wrong metric—market cap, the scarce and pretty figure—instead of the one with a delivery date—FDV and the calendar. The shape of the unlock matters as much as the date; the recipient predicts the sale; the price moves before, not on the day; and the supply that hasn't arrived yet is as real as the one already circulating, it's just not visible yet. The action that separates the informed investor from the rest takes five minutes: open the token's calendar, see when the next big tranche is, who it goes to, and what percentage of the supply it represents.

Market cap tells you what it's worth today; the unlock calendar tells you who is going to sell tomorrow. Only one of those is insider information, and it's the free one. It's the closest you'll ever get to having the insider's edge without breaking any laws.
