Editor’s Update: October 14, 2026. Ethena’s October 5 unlock has now passed. A CryptoTicker follow-up reports ENA fell about 11.6% over the week after it and that USDe supply stood near $4.8 billion, so the revenue-funded buyback (which needs $7.5 billion of USDe) is still switched off. The 1.41 billion versus 171.88 million disagreement is still not settled by Ethena itself: a KuCoin analysis on October 4 concluded the 171.88 million figure reflects the old monthly schedule and that the most consistent gross figure was about 1.5 billion ENA (roughly 1.40 billion accelerated investor tokens plus 93.75 million core contributor tokens), noting the Foundation has bought back some locked positions, so net tradable supply may be lower. For Arbitrum, the next 92.65 million ARB tranche is due mid-October; most trackers list October 16, while one source gives October 15. Treat dollar values with care: at roughly $0.20 per ARB the tranche is worth about $19 million, and higher figures in some alerts are older price snapshots. Recipient splits also differ between sources.
Editor’s review, October 1: Sui’s figure was re-checked (see the Sui section), 2Z’s 1.66 billion tokens, about $113 million and 47.69% of released supply were confirmed by a KuCoin News roundup, and tenses were updated for the Oct 1 and Oct 2 events. Ethena’s amount and Arbitrum’s exact date remain unconfirmed by the projects.
Quick answer: Four token unlocks dominate October 2026. Sui’s monthly tranche landed on October 1, DoubleZero (2Z) releases a 1.655 billion token cliff at 00:00 UTC on October 2, Ethena (ENA) was scheduled to free its final investor allocation on October 5 (trackers disagree on how many tokens that actually involved), and Arbitrum (ARB) releases its usual monthly batch in mid-October. By size against existing supply, 2Z (roughly 47.7% of circulating supply) and ENA (roughly 14%) are the big ones. SUI and ARB are small, routine tranches. Trackers disagree on several numbers, which this guide flags as we go. This is analysis, not a price call.
The October 2026 unlock calendar at a glance
Here’s the short version, using the figures that appear most consistently across the sources we checked. Dollar values move with price, so treat them as approximate.
- Oct 1, Sui (SUI): monthly unlock. Tokenomist-based coverage puts it near 13.26 million SUI (about 0.32% of released supply, roughly $17 million). One calendar lists about $61 million instead. More on that gap below.
- Oct 2, DoubleZero (2Z): 1.655 billion 2Z released in a single cliff, equal to about 47.7% of the circulating supply counted by CoinGecko in early September.
- Oct 5, Ethena (ENA): about 1.41 billion ENA, roughly 14% of circulating supply, the last investor tranche. The exact amount is a derived estimate, not an official Ethena figure. Update, October 6: now that the date has passed, trackers still don’t agree. DropsTab and a Cryptonomist roundup list about 171.88 million ENA (93.75 million to core contributors and 78.13 million to investors, around $41.5 million), which looks like the old monthly schedule, while CoinMarketCap-based coverage keeps the roughly 1.41 billion figure. We couldn’t confirm which applied from Ethena itself.
- Mid-October, Arbitrum (ARB): about 92.65 million ARB, around 1.4% of circulating supply. Sources give the date as October 15 or 16.
If you only remember one thing: the headline dollar number tells you very little. The percentage against what’s already trading, and who receives the tokens, tell you far more.
How to read an unlock: size versus circulating supply
A headline like “$114 million unlock” sounds enormous until you notice the token has a $4 billion market cap. Equally, a “$20 million unlock” can be a big deal for a coin with a thin market. So start with a ratio.
Unlock size divided by circulating supply is the first number to check. It shows how much new supply could reach the market relative to what’s already there. Under 1% is routine. Somewhere between 1% and 3% is noticeable. Anything above 10% is a structural event.
The second question is who gets the tokens. Tokens going to a foundation treasury, a validator set, or an early investor with a 3-year-old cost basis all behave differently. A recipient with a very low cost basis has a lot of room to sell at a profit. A recipient who needs the token for governance or operations may hold.
The third is cliff versus linear. A cliff dumps a lump sum on one date. Linear vesting drips out daily or weekly, so the market absorbs it gradually. Our explainer on token vesting and unlock schedules covers the mechanics in more detail.
And one honest caveat. “Circulating supply” isn’t written anywhere on a blockchain. It’s a label a data provider assigns, and providers draw the line differently. CryptoTicker’s 2Z analysis points out that CoinGecko counts Foundation tokens as circulating while DefiLlama doesn’t, which changes the dilution percentage materially. If two sites show different percentages for the same unlock, that’s usually why. For a broader grounding in supply design, see what tokenomics is and how to evaluate a supply model.
October 1: Sui’s monthly unlock
Sui uses a recurring monthly schedule, so this one isn’t a surprise. Tokenomist’s Sui page lists the October 1 event under the Community Reserve allocation, with a total supply of 10 billion SUI and roughly 4.1 billion circulating (about 41%).
The numbers disagree here, and it’s worth being upfront about it. A BeInCrypto weekly roundup, and a KuCoin news item citing PANews, both put the tranche at about 13.26 million SUI, worth roughly $17 million and 0.32% of released supply. In that breakdown, early contributors get about 7.19 million, the community reserve about 4 million, and Mysten Labs about 2.07 million. Tokenomist’s own dashboard, as we read it, also showed a small figure (around $15 million, 0.3% of circulating supply) for the week.
Meanwhile, CryptoTicker’s Q4 calendar lists the Sui unlock at about $61 million, and an independent governance report on GitHub lists 64.2 million SUI (about 1.57%) for October 1. We couldn’t reconcile these against Tokenomist or a project primary source. The gap may come from different tranche definitions or different data snapshots. Update: a KuCoin News unlock roundup published this week also lists 13.26 million SUI (about $16.84 million, 0.32% of released supply) for October 1, and Tokenomist’s Sui page now shows the next event as November 1, which fits an October 1 tranche that has already been processed. That makes the $61 million figure look like an outlier. Treat any single number with caution and check the live tracker.
Either way, this is the kind of unlock the market has seen every month. Under 2% of supply, a known schedule, and no change of pace.
October 2: DoubleZero (2Z), the cliff that stands out
DoubleZero is a network built around high-performance connectivity for blockchains, and its token is newer to the market, so its unlock calendar carries more weight than an established token’s would.
According to CryptoTicker and BeInCrypto, 1.655 billion 2Z unlocks on October 2 at 00:00 UTC in one cliff. CryptoTicker computes 47.7% by dividing by about 3.47 billion circulating tokens as of September 2, 2026. Total supply is 10 billion. Tokenomist’s page shows roughly 5.11 billion tokens in circulation at the time we checked, which suggests a different counting method, and which would make the same unlock a smaller percentage of the then-current float. That’s the definition problem from the previous section in action.
The recipients matter more than the headline. CryptoTicker’s breakdown lists:
- Jump Crypto: 575 million
- Malbec Labs: 350 million
- Institutions: 300 million
- Team: 250 million
- Contributors: 100 million
- Builders: 50 million
- Validators sale: 30 million
By that analysis, insiders hold about 74% of the cliff. Note that one calendar describes the recipients as “predominantly validators,” which doesn’t match the bucket breakdown above. We’d go with the bucket data, and we couldn’t verify the allocations against a DoubleZero primary document ourselves.
Dollar value also varies by source and snapshot: about $88 million at the September 2 price, $113-116 million in other coverage, and about $124 million in the governance report. After the cliff, six buckets also begin linear vesting at about 31.1 million 2Z a week, according to CryptoTicker.
October 5: Ethena’s final investor unlock
Ethena’s situation is a change of schedule rather than a surprise. According to a KuCoin blog summary of an August 27, 2026 announcement, and TokenPost’s September 28 report, Ethena is consolidating all remaining investor allocations into a single release on October 5. The original schedule would have run to roughly March 2028, at around 78 million ENA a month, so the new date pulls the finish forward by about 17 months.
The size: roughly 1.41 billion ENA. CryptoTicker states plainly that this number is derived by Unlocks from the published vesting schedule and hasn’t been confirmed by Ethena. Against Tokenomist’s circulating supply of about 10.095 billion ENA, 1.41 billion works out to roughly 14%, which matches the coverage.
The USD value is where sources split hardest, because ENA’s price differs across reports. CryptoTicker’s calendar gives about $381 million, while its dedicated article cites $210-240 million at $0.15-$0.17 a token, and the governance report says about $213 million. Tokenomist showed ENA near $0.26 when we looked. We can’t tell you which snapshot is right on the day. What’s solid is the token count and the percentage.
Two details add context. The Ethena Foundation reportedly bought out some seed investors who had already sold, though the buyout prices and amounts weren’t disclosed. And the revenue-funded buyback proposal won’t switch on October 5, since it needs USDe supply of $7.5 billion and reports put it near $4 billion. TokenPost also notes a StablecoinX holding address with about 3.03 billion ENA has its lockup restrictions removed on October 5, although sales reportedly need Foundation approval and five business days’ notice. A separate smaller 40.63 million ENA Foundation unlock is listed for October 2 on Tokenomist and PANews.
Mid-October: Arbitrum’s routine monthly batch
Arbitrum is the quiet one. Its team and investor allocations vest monthly at 92,645,833 ARB (56.125 million to the team, 36.52 million to investors, per CryptoTicker). The big cliff happened in March 2024, when 1.1 billion ARB was released at once, and the remaining monthly tranches are small by comparison.
Against Tokenomist’s circulating supply of about 6.79 billion ARB, 92.65 million is roughly 1.37%, in line with CryptoTicker’s 1.32-1.4%. Dollar value depends on price: around $19-20 million in the October calendars, at ARB near $0.20-$0.21. One Tokenomist alert we saw cited $41.2 million, which looks like an older price snapshot.
Date discrepancy: CryptoTicker’s schedule lists October 15, while its calendar and Tokenomist list October 16. Tokenomist’s page also labels the tranche as released to the DAO Treasury, which differs from the team and investor split elsewhere. We couldn’t resolve that from the pages available. The lockup is expected to finish between mid-February and end of March 2027 depending on how the vesting terms are read.
What unlocks can and can’t tell you
Unlock calendars are useful because they’re one of the few supply events you can see coming. Research cited in the governance report from Keyrock (16,000-plus historical unlocks) claims most unlocks create negative price pressure, but we haven’t verified that dataset ourselves, and a price effect still depends on demand, positioning, and how much was already priced in. Plenty of well-publicized unlocks have come and gone with muted reactions, and some have been followed by drops. A calendar entry isn’t a forecast.
A practical checklist when you see a new unlock headline:
- What percentage of circulating supply is it, and which provider’s circulating supply?
- Cliff or linear?
- Who receives it, and what’s their likely cost basis?
- Is it scheduled and known, or a change from the schedule (like Ethena’s)?
- Does the token have steady demand that can absorb the new supply?
We covered a smaller set of the same idea in Solana token unlocks to watch in September 2026.
FAQ
What is a token unlock?
It’s the date when previously locked tokens become transferable. Unlocking doesn’t mean the holder will sell, only that they now can.
Which October 2026 unlock is largest relative to supply?
DoubleZero (2Z), at roughly 47.7% of circulating supply by CryptoTicker’s calculation. Ethena’s final investor unlock is next at around 14%.
Why do different sites show different unlock numbers?
Mainly because of different circulating supply definitions, different price snapshots, and in some cases different tranche definitions. Always check the token count and the date on the tracker itself.
Is Ethena’s October 5 figure official?
Not the exact amount. The 1.41 billion ENA figure is derived by Unlocks from the vesting schedule, and Ethena hasn’t published it, according to CryptoTicker.
Does an unlock mean the price will fall?
Not automatically. It adds potential supply, but the outcome depends on recipients and demand.
Key takeaways
- Oct 1 SUI and mid-Oct ARB are small, scheduled monthly tranches, roughly 0.3-1.4% of supply.
- Oct 2 2Z is a 1.655 billion token cliff, about 47.7% of circulating supply on one calculation, with insiders holding most of it.
- Oct 5 ENA is a final investor unlock of about 1.41 billion tokens (roughly 14%), pulled forward by about 17 months. The exact amount is unconfirmed by Ethena.
- Always compare unlock size to circulating supply, check cliff versus linear, and look at who receives the tokens.
- Sources disagree on Sui’s amount, ENA’s dollar value, and ARB’s date. Verify on the day.
