How token unlocks move a token's price, with real examples and numbers

A project's website says "circulating supply: 400 million." A year later it's 900 million, and the price is down 60% even though nothing about the product changed. That gap is almost always token unlocks doing their job, quietly, on a schedule set at launch.

What exactly is a token unlock

Most tokens aren't fully liquid on day one. Teams, early investors, and advisors get allocations locked in a vesting contract, usually with a cliff (say 12 months of nothing) followed by monthly or quarterly releases over 2-4 years. When a lock period ends, those tokens become transferable and can hit exchanges. That event is the unlock.

Take Arbitrum's ARB token. At the March 2023 airdrop, circulating supply was about 1.275 billion out of a 10 billion total. In March 2024, a cliff unlock released roughly 1.1 billion ARB to the team and investors, nearly doubling circulating supply in a single event. Arbitrum's own tokenomics page lays out the four-year vesting schedule investors could have checked well before that date. ARB dropped from about $1.35 to under $1.00 in the weeks around that unlock, though a broader market pullback was mixed in too.

Why does more supply hurt the price

This is basic supply and demand, but the mechanics matter. Unlocked tokens usually go to two kinds of holders: team members whose paper wealth just became liquid, and VC funds that bought in at a steep discount during a seed or private round. Both have a rational reason to sell. A VC that paid $0.10 per token and can now sell at $1.00 has a 10x already locked in, no matter where the price goes next. Vesting doesn't create new buyers to absorb that supply; it just creates new sellers. Unless daily trading volume and organic demand can soak up the added float, price finds a lower equilibrium.

The size of the move tends to track the unlock as a percentage of circulating supply, not the percentage of total supply. A 5% unlock relative to total supply sounds small, but if circulating supply is only 15% of total, that unlock could be a 30%+ jump in tradable tokens overnight. Token Unlocks tracks these ratios for most major tokens if you want to check a specific date.

Does the market always sell off

Not always, and that's the part traders get wrong by assuming unlocks are automatically bearish. Solana's SOL had large monthly unlocks through 2021-2022 that mostly got absorbed during the bull run because demand from new buyers outpaced the added supply. The direction of the move depends on three things: how much of the unlock is actually sold versus staked or held, what the broader market is doing that week, and whether the unlock was already priced in by traders front-running the date. Sophisticated funds often short a token in the days before a known unlock and cover after, which means some of the damage happens before the tokens even move on-chain. By the time retail notices the calendar date, the selling pressure may already be reflected in price.

There's also a mechanical wrinkle: some "unlocks" release tokens to a foundation or treasury, not directly to sellers. Those don't hit the market immediately, and conflating every scheduled release with a dump is a common reading error.

What should you check before an unlock date

Look up the exact unlock size as a percentage of current circulating supply, not total supply, using a tracker or the project's own vesting docs. Check who receives the tokens: team and insiders behave differently than a DAO treasury or staking rewards pool. Look at 30-day average trading volume against the unlock's dollar value; if the unlock is worth more than a few days of volume, it's a real liquidity test. And check whether the price has already drifted down in the two to four weeks before the date, which suggests the move is partly priced in already. None of this predicts direction with certainty, but it tells you whether you're looking at a rounding error or a supply shock.
