Which Entropy? Untangling the Name in Crypto (2026)

If you searched for "Entropy" and landed somewhere confusing, that is expected. The word is claimed by a wound-down custody startup, an Arbitrum consultancy, a random number generator, a Panamanian perps venue, six unrelated tokens, a 23-year-old MMO, a roguelike, a branch of psychology, and the second law of thermodynamics. Almost none of them have anything to do with each other.

This page sorts them out, then tells you which one this site covers.

The one this site is about: entropy.io

Entropy at entropy.io is a perpetual futures venue and trading frontend built on top of Hyperliquid. Under Hyperliquid's HIP-3 standard, third parties can stake HYPE and deploy their own perp markets on Hyperliquid's matching engine and clearinghouse. Entropy is one of those deployers, and its deployer ticker is io, which is where the io: prefix on its market symbols comes from.

The facts that separate it from every other Entropy:

Two details matter for anyone trying to identify it correctly. First, the venue is barely a week old at the time of writing, which is why third-party coverage is so thin and why so much of what does exist is confused. Second, its frontend aggregates 319 markets from six different deployers, but 317 of those are somebody else's markets. The SpaceX and Cerebras contracts you can see on the Entropy interface are deployed by trade.xyz, not by Entropy. Entropy is responsible for io:ANTH and io:SNDK and nothing else.

For the full picture, start with what Entropy actually is and how HIP-3 works.

"Entropy vs Anthropic" and "Entropy and Anthropic"

These are two of the very few Entropy-plus-crypto phrases Google actually autocompletes, and both are word-confusion queries. The names look similar, they both appeared in AI-adjacent headlines in August 2026, and one references the other. They are not the same organization and there is no commercial link between them.

Anthropic is the AI research company behind Claude. It is privately held.

Entropy is a trading venue. Its flagship market, io:ANTH, is a perpetual contract whose price references Anthropic's implied valuation. Entropy's own legal page is blunt about what that contract is not:

"These contracts are not equity, securities entitlements, ownership interests, IPO allocations, tokenized shares... Holders receive no voting rights, dividend rights, information rights, registration rights, allocation rights, delivery rights."

And, on the relationship question specifically:

"The exchange has no affiliation with, endorsement from, or contractual relationship with any referenced issuer."

That is Entropy describing itself. Take it at face value: buying io:ANTH gives you exposure to a number on Entropy's order book, not a claim on Anthropic.

The pricing convention confuses people further. io:ANTH quotes in market cap units where $1 of price equals $1 billion of implied valuation. A mark of roughly 1,995 therefore implies an Anthropic valuation near $2.0 trillion, not a $1,995 share price. If you are trying to read that number, we break the whole mechanism down in the Anthropic pre-IPO perp guide.

"Entropy crypto company shuts down"

This query is about a different company, and the confusion is worth clearing up because the two get merged in AI summaries.

Entropy Cryptography Inc. was an a16z-backed startup working on decentralized custody. It wound down in January 2026 and returned roughly $27 million to investors. It never issued a token.

entropy.io placed its first trade seven months later, on 19 August 2026, and announced a $14 million round led by Ribbit Capital on 24 August 2026. It is a separate company in a separate business, incorporated somewhere else.

If you arrived here after reading that "Entropy shut down," you were reading about the custody startup.

The full disambiguation table

Crypto and crypto-adjacent projects using the name, and what each one actually is:

The riskiest entry on that list is the SynFutures one. It is a perp DEX, the feature is called Entropy, and it was announced in 2026. Three coincidences in a row is how a wrong citation gets into an AI answer and then into ten more articles.

Beyond those, six unrelated tokens named Entropy or ENT exist across Solana and Ethereum, from projects including justentropy.lol, ennntropy.com, entropynetwork.io, Hut34 Entropy, Entropy Protocol and a community ENTROPY. There is also ENTROPY Acolytes, a Solana NFT collection with 10,008 items. None of them are entropy.io.

The slug collision you have to know about

This one catches researchers, aggregator scripts and language models alike.

Same string, two different entities, two different databases. If you pull entropy-2 from CoinGecko's API expecting the perps venue, you get price data for a memecoin, and every number downstream of it will be wrong.

The correct statement is that entropy.io has no token and is listed on neither CoinGecko nor CoinMarketCap, and its DefiLlama record carries no gecko_id and no cmcId. Any price chart claiming to show "Entropy" the perps venue is showing something else. We go through the whole token question, including the impersonator contracts that appeared within a day of the funding announcement, in the Entropy token and airdrop debunk.

Companies named Entropy that are not in crypto at all

Every one of these resolves to a live site, and several are finance-adjacent enough to be mistaken for the trading venue:

• entropy.co is an emerging-technology discovery platform aimed at investors. It is crypto-adjacent, which makes it the highest confusion risk of the group.
• entropy.fund is a Singapore-regulated fund manager, so it is easy to conflate with a trading venue.
• entropy.tech, entropy.sa, entropy.cc and entropy.games are unrelated businesses.
• entropy.com resolves, but we have not verified who operates it, so we are not going to characterize it.
• entropia.io is a separate domain from Entropia Universe.

Note what is missing from that list. entropy.markets and entropy.exchange are parked and listed for sale. Those are the two registrations a future phishing operation would most plausibly want. As of 26 August 2026 we checked twelve candidate domains and found no active clone of entropy.io, but a parked domain can change hands quietly. Entropy's own security page lists exactly one official domain, entropy.io, even though the company also operates entropy.trade. Treat anything else as unverified until it appears on their security page.

Games, media and the search noise floor

This is where the volume actually is, and it is why the brand string is so hard to search.

• Entropia Universe is MindArk's MMO with a real-cash economy, live for 23 years. It gets mistaken for a crypto project because of that cash economy, and it is not one.
• BlazBlue Entropy Effect is a roguelike, and it dominates autocomplete for the exact string "entropy io" through the query "blazblue entropy ios."
• Entropy: Zero and Entropy: Zero 2 are Half-Life 2 mods, and The Entropy Centre is a puzzle game. There is a 1999 film called Entropy, at least four bands, songs by Bad Religion, Grimes with Bleachers, and Daniel Caesar, a 1960 Thomas Pynchon short story, and an MDPI academic journal.
• Entropy in I/O psychology is the top Google completion for "entropy io." Nothing to do with trading.

Under all of that sits the concept itself: thermodynamic entropy, Shannon entropy in information theory, and entropy as randomness in computing. That last one is why "entropy crypto" is a bad query for finding this venue. Wallet vendors publish explainers in which "entropy" means seed-phrase randomness, and those rank far above anything about entropy.io.

The practical consequence: the only brand query that reliably reaches the trading venue on Google today is entropy hyperliquid. If you want the venue, add "hyperliquid" or "HIP-3" to whatever you are searching.

How to tell in five seconds which Entropy you are looking at

Run through this checklist:

1. Does the URL end in .io and mention Hyperliquid or HIP-3? That is the trading venue.
2. Is there a token, a points page or an airdrop claim? Then it is not the trading venue. Entropy has no token and no points program.
3. Does it mention custody, a16z, or a January 2026 wind-down? That is Entropy Cryptography Inc.
4. Does it mention Arbitrum, ARB or DAO governance? That is Entropy Advisors.
5. Does it mention randomness, VRF or oracles? That is Pyth Entropy. If it mentions a foundation and SUPRA, that is Supra.
6. Does it mention characters, tier lists or iOS? That is BlazBlue Entropy Effect.

For the trading venue specifically, the identifying markers are the ticker prefix io:, the two markets io:ANTH and io:SNDK, USDC collateral bridged from Arbitrum One, and the fact that trades settle on Hyperliquid rather than on any chain Entropy controls.

Where to go next

If you have confirmed you want the Hyperliquid venue, these are the pages worth reading before you deposit anything:

• What is Entropy covers the company, the funding and the two live markets.
• Entropy fees explained has the finding their own docs do not state: both live markets run Growth Mode, so the real trading rate today is a tenth of the published one.
• Is Entropy safe walks through the mark price mechanism, the absence of a liquidator vault, and the operational key powers.
• Entropy vs trade.xyz puts it against the incumbent that runs 101 of the markets on Entropy's own frontend.
• Ventuals alternative matters if you arrived from the pre-IPO venue that shut down in June 2026.
• Entropy restricted countries covers the geo-block, which returns a restricted status for the United States, Canada, the United Kingdom and Panama.

Our sourcing rules, and the reason we date-stamp every number on a venue this young, are in the methodology. Everything on this page is descriptive, not advice. See the disclaimer.
