The largest airdrops one year later: UNI, ARB and HYPE

93% of those who received the UNI airdrop in September 2020 sold all of their tokens, and more than three-quarters did so within the first seven days. That figure, measured wallet-to-wallet by Dune Analytics, is the outcome of one of the three largest free distributions in history (an airdrop is the delivery of tokens at no cost to users who have already interacted with a protocol). The other two — Arbitrum's ARB in 2023 and Hyperliquid's HYPE in 2024 — ended at opposite extremes: one plummeted suddenly and remains 97% below its peak; the other multiplied its value and remains the flagship asset of its protocol more than a year and a half later. This article contrasts the three with dated figures — distribution size, real retention, launch price versus current price, and the mechanism that sustains (or fails to sustain) the token — and explicitly states where the evidence of one is not comparable to another.

Why did the same mechanism produce owners in one case and sellers in another?

Three distributions, three opposite outcomes. Uniswap delivered UNI on September 17, 2020 (150 million tokens, 15% of the genesis supply), Arbitrum distributed ARB on March 23, 2023 (over 1 billion, around 12% of the supply), and Hyperliquid distributed HYPE on November 29, 2024 (310 million, 31%). The promise was the same in all three: to turn the wallets that had used the protocol before it had a token into aligned owners. The practice, measured over the years, was much more uneven: the same gesture produced communities that sold within hours and communities that still hold the token today as a central piece of their thesis.

The decisive difference came after the distribution and had nothing to do with its size or market timing: it depended on what the token received once distributed — a revenue flow from the protocol to back its value, or merely the expectation that someone else would pay a higher price. These three cases cover four years of that evolution and allow for a before-and-after comparison with verifiable data.

How many UNI airdrop recipients sold their tokens?

Uniswap distributed UNI on September 17, 2020, and reserved 15% of the genesis supply — 150 million UNI, of which about 100 million went directly to user wallets (the rest to liquidity providers and SOCKS holders) — with 400 UNI for each of the more than 250,000 wallets that had used the protocol. At the prices of those early days (between $2 and $4 per token), those 400 UNI were worth around $1,000; at the May 2021 peak, when UNI touched $44.92, the same allocation would have been worth nearly $18,000.

Almost no one waited to find out. The Dune Analytics analysis The Uniswap Airdrop — Lessons for the Industry tracked original recipients wallet-to-wallet and found that 93% had sold all of their UNI, more than 75% within the first seven days, and that only about 7% still held any tokens. Activity didn't stick around either: airdrop recipients who continued to trade weekly dropped from over 62,000 in September 2020 to about 10,000 a year later, and to barely 4,000 by September 2022, according to the same study.

The UNI data is the most solid of the three precisely because it comes from wallet tracking with a public date and methodology. It is the benchmark against which the other two cases are measured: a direct measurement, not a price average interpretable in various ways. This is why the Dune study became the industry's canonical example of how difficult it is to build community loyalty with a free distribution: giving away tokens is not the same as creating owners, and the gap between the two was quantified for the first time with that 93% figure.

What happened to ARB after the Arbitrum airdrop?

Arbitrum distributed over 1 billion ARB — around 12% of its supply — among some 625,000 wallets on March 23, 2023, in what was the largest airdrop for a Layer 2 network (a blockchain built on top of Ethereum to lower transaction costs) up to that point. The claim portal crashed and network gas fees skyrocketed during the first hour, with everyone selling, moving, or depositing their tokens at once. Within two hours, the token's market cap was near $1.7 billion, according to Fortune.

Here it is useful to separate two prices that are often conflated. In pre-listing markets — IOU contracts and futures traded before the token actually existed — some exchanges saw prices well above $10, and the first spot trades were equally chaotic, touching $3.99 on Uniswap, according to CoinDesk. The price stabilized around $1.40 in the first few hours, with a close near $1.25 on the first day. Those who bought into the pre-market euphoria lost most of it immediately; those who received the airdrop and sold on the first day did so near that $1.25 mark.

The rest is a long decline. ARB reached its all-time high of $2.40 on January 12, 2024, and has fallen steadily since then: in July 2026, it trades around $0.08, 97% below that peak, after hitting an all-time low of $0.07 in June 2026. There is no public wallet retention study for ARB equivalent to the one for UNI, so here the outcome is read through price, which serves as a proxy for recipient behavior.

Why did the HYPE airdrop retain value?

Hyperliquid distributed about 310 million HYPE — 31% of the total supply, the highest proportion of the three — among more than 94,000 wallets on November 29, 2024, with no prior investor round, no centralized exchange listing campaign, and no manual claim required. At the genesis event, each HYPE was valued at around $3.90; on the first day, the price moved between a low of $3.20 and nearly $7.56 in the first trades.

From there, the trajectory diverges completely from ARB. HYPE reached an all-time high of $76.70 on June 16, 2026, and as of July 28, 2026, it trades around $55. Taking the $3.90 genesis valuation as a base, that equals about 14 times the launch price; if the debut day low ($3.20) is used, the multiple approaches 17x. This is an important correction to the "28x over a $2 launch" figure circulating in some summaries: HYPE never traded at $2 — its all-time low was $3.20 on distribution day — so the real multiple is lower, though it remains the only one of the three clearly above its initial price.

There is another difference that doesn't appear on the price chart: nearly twenty months after the distribution, HYPE remains the central asset of Hyperliquid, not a governance token that most of the community abandoned. The distribution was done without a private investor round that had locked tokens waiting to be sold, and without the simultaneous listing on centralized exchanges that usually coincides with the first wave of selling. This design — more supply for users, less for intermediaries with an incentive to exit — is part of why the initial selling pressure did not resemble ARB's.

The piece that distinguishes HYPE is not the price itself, but what sustains it, and that connects with the analysis in the Hyperliquid vs. GMX vs. dYdX comparison: the token receives a structural revenue flow that UNI and ARB lacked for years.

UNI vs ARB vs HYPE: The Outcome Table

Placed in a table, the pattern is counterintuitive: the largest distribution in proportion to supply (HYPE, 31%) is the only one that retained value.

The price columns tell the broad story; the last row tells the fine detail. HYPE had a buyback mechanism from day 1; UNI added it in December 2025 and ARB announced it in July 2026.

Why isn't retention for UNI, ARB, and HYPE measured the same way?

An honest contrast requires stating that the three cases are not measured with the same yardstick, and this asymmetry is part of the analysis, not a flaw to be hidden. Only UNI has a primary seven-day wallet-to-wallet retention study: the Dune Analytics work that sets the 93% total sales figure. For ARB, there is no equivalent public study tracking how many recipients still hold the token; what exists is the immediate price drop on the first day and the 97% crash over three years, which is used here as a behavioral proxy, not a direct measure of wallet retention.

For HYPE, the situation is similar: there is no seven-day retention study comparable to UNI's, so its outcome is inferred from the price trajectory and the fact that it remains the central asset of its protocol nearly twenty months later; a census of wallets still holding it is missing. In summary: one direct seven-day measure for UNI (Dune, 93%), and two price proxies for ARB (−97%) and HYPE (−28% from peak).

Are UNI and ARB now copying the HYPE model?

The most revealing detail of 2026 is that the two airdrops that "failed" in retention are adopting, years late, the same idea that HYPE applied from genesis: connecting the token with real protocol revenue. Hyperliquid allocates 97% of protocol fees to its Assistance Fund, which buys HYPE on the open market automatically and continuously, without the need to vote on each buyback. Since launch, the protocol has accumulated over $1 billion in revenue, with an annualized rate of ~$700-840 million in mid-2026, and the fund had accumulated tens of millions of HYPE removed from circulation; in a validator vote on December 24, 2025, involving ~37 million HYPE (~$1 billion) and with 85% in favor, the community recognized those tokens as burned, reinforcing the deflationary effect. This is the mechanism that sustains the "users to owners" thesis developed in the analysis of Hyperliquid revenue fundamentals.

On the other hand, Uniswap activated its fee switch — the so-called UNIfication — in December 2025: since then, a portion of protocol fees is used to burn UNI and give holders a claim on that revenue. Arbitrum went a step further in July 2026: Offchain Labs, through Steven Goldfeder on July 9, 2026, announced that 100% of Arbitrum One fees and 10% of each Orbit chain's fees would flow into the treasury controlled by ARB holders — not a direct distribution — which pushed the token up 13% on the announcement. The irony is evident: both protocols are now building, with the original community already sold out, the revenue backing that HYPE had from minute one. The mechanics of why the absence of such backing subjects a token to continuous selling pressure are explained in the guide on token unlocks.

What do UNI, ARB, and HYPE teach airdrop farmers in 2026?

The question asked by those accumulating points today on new perpetuals platforms (futures without expiry) is not whether the airdrop will arrive, but what will happen to the token after the distribution. The three historical cases offer a measurable pattern, not a recommendation:

1. The percentage of supply distributed did not predict the result: HYPE distributed twice as much as ARB in proportion and fared better.
2. Pre-market euphoria was a poor indicator: ARB IOUs above $10 evaporated to $1.40 within hours.
3. What did separate the three was whether the token received a revenue flow from the protocol that gave a reason to hold it beyond speculation.

That is the framework with which to read the next generation of distributions. Aster, Lighter, and edgeX recently crossed that line — they held their TGE (Token Generation Event) on September 17, 2025, December 30, 2025, and March 31, 2026, respectively; Lighter saw $250 million withdrawn in the first 24 hours — but they have only just started the clock: we will only know if they create owners or sellers when their tokens have been trading for months or years and someone can track the wallets, as Dune did with UNI. Until then, the dated history of UNI, ARB, and HYPE is the only testbed with real results on the table.
