Entropy.io brings perpetual futures tied to private companies, public stocks, and ETFs into one trading interface on Hyperliquid. That makes an unusual mix of markets easy to explore. It also makes it easy to miss a crucial distinction: a contract linked to Anthropic is not an Anthropic share, and a stock perp does not behave exactly like an ETF perp. This review looks at what Entropy offers, how the interface feels in use, what trading might cost, and where the risks become harder to see.
The public side of the platform is genuinely useful. Prices, order books, funding, and order controls are visible before sign-in, and moving between markets takes only a few clicks. The tougher part is understanding the contract behind each ticker. Entropy makes the tools accessible; it still asks the user to do a fair amount of homework on pricing rules, leverage, and fees. Experienced USDC perp traders will find more to like here than someone hoping to buy private-company shares before an IPO.
What is Entropy.io?
Entropy is a trading interface for perpetual markets deployed through Hyperliquid HIP-3. Its deployment is called io. Entropy's terms identify Bursa Global Inc. as the operator of the interface, while Hyperliquid supplies the underlying trading infrastructure. Positions use USDC as collateral and give traders long or short exposure to a reference market. They do not convey ownership of the referenced company, fund, or index.
The project's X account says it raised $14 million in a round led by Ribbit Capital and launched with a $40 million HYPE stake on August 24, 2026. Those are company claims, useful as background but not a substitute for judging the product itself. The more immediate question is whether Entropy helps users understand the markets they are about to trade.
Which markets can you trade?
Entropy's market selector has tabs for Entropy, HIP-3, commodities, crypto, FX, indices/ETFs, pre-IPOs, and stocks. On October 28, the search box showed 329 live markets across the wider interface. Switching to the Entropy tab brought the visible count down to 12 in our capture. The larger number should not be read as the number of markets deployed by Entropy; both counts are a snapshot, not a permanent catalogue.
The order form looks familiar across these markets, but the contracts do not share one pricing playbook. Stock perps use a public-market reference during the underlying exchange's session and a different oracle regime outside those hours. Pre-IPO perps deal with private-company data and have their own resolution rules. That distinction matters more than the convenience of seeing every ticker in one menu.
Using the public trading interface
Finding a market
Selecting OAI changed the trade page to io:OAI, with a new chart, mark price, oracle price, and order book. We also opened io:SNDK and io:DRAM. All three pages loaded without an account, making it possible to compare a pre-IPO market, a stock perp, and an ETF perp before starting the sign-in flow.
Each trading page puts the mark, oracle, funding countdown, 24-hour volume, and open interest above the chart. The order book and trade form sit beside it. Recent trades also updated while we watched the Trades tab. This is a strong first impression for someone assessing a market before logging in.
The missing piece is context. Last trade, mark, and oracle prices can diverge, yet the trading screen does little to explain why. For pre-IPO markets, the mark feeds unrealized PnL, margin, liquidation, and TP/SL triggers. A busy tape or high 24-hour volume does not tell you what a large order would actually cost at the top of the book.
Order controls: capable, but easy to rush
The public Market form shows Long/Short, a USDC size field, isolated margin, leverage set to 5×, Reduce Only, and TP/SL. Max Slippage was enabled at 8.00% on the screens we opened. That is the maximum slippage the form would permit for a market order, not a prediction of the fill. It is one of the first settings worth checking, particularly on a thin market.
Opening the leverage control on the Anthropic market showed a 1×–15× range on October 28. The SNDK page displayed 15× and DRAM 25×; Entropy's DRAM specification also lists 25×. Higher leverage lowers the initial collateral needed for the same position size, but losses consume that collateral more quickly.
Turning on TP/SL revealed fields for target and stop prices, gain, and loss. Hyperliquid's order guide says the mark price triggers these orders; the eventual fill may differ, and a limit-based exit may not fill at all. The controls are useful, but they are not a guaranteed exit price.
The Limit tab adds a price field and time-in-force choices: GTC, IOC, and ALO (Post Only). Those settings determine whether an order can rest on the book or whether its unfilled portion is cancelled; Hyperliquid documents the differences. Entropy's Pro menu also lists Chase, Scale, Stop Market/Limit, Take Profit Market/Limit, and TWAP. This is a substantial toolkit for an experienced trader, although seeing a menu option says nothing about fill quality under live conditions.
Signing in and account-only features
Log in opens a Privy panel with email and wallet options. The wallet list includes MetaMask, OKX Wallet, Coinbase Wallet, Rainbow, and Phantom. Entropy's quickstart describes funding an account with USDC and enabling an agent wallet after sign-in. Our session ended at the wallet selection screen, so the deposit and trading flow remains outside this hands-on assessment.
The Leaderboard is public, with 1D, 7D, and 30D views plus PnL and volume columns; the 7D table loaded 100 rows and pagination in our session. It offers a look at activity on the venue, not a forecast of anyone else's returns. Referrals and account-specific Funding ask for login, so their personal balances and rewards are not visible from the public interface.
Fees, funding, and rebates
Entropy's published pre-IPO, stock, and index fee pages give a standard HIP-3 base rate of 0.030% maker and 0.090% taker on notional value. Volume tiers, staking discounts, rebates, and a market's growth-mode status can change the effective rate.
For a 1,000 USDC notional position, opening and closing as a taker at that base rate would cost about 1.80 USDC in trading fees. At 5× leverage, the simple initial-margin calculation comes to roughly 200 USDC. Neither figure includes spread, slippage, funding, or price movement; it is an illustration, not an account-specific quote.
Entropy's referral documentation describes a self-rebate, a reward for referring traders, and a benefit for referred traders. The published percentages apply to Entropy's share of trading fees, not the entire fee. A self-rebate and referred-user benefit do not stack on the same trade. The login gate prevented us from checking a real account's rebate balance or withdrawal.
Funding can be a cost or a payment received, and it moves with the market. On Entropy's pre-IPO contracts, it settles hourly between longs and shorts under a market-specific multiplier. A rate visible in one screenshot should not be projected across an entire holding period or copied to every market type.
Risks that matter beyond the order form
The oracle changes with the asset class. Entropy's pre-IPO oracle combines order-book information with private-market data supplied onchain by RedStone. Stock and index markets also have to account for hours when their underlying exchanges are closed. Seeing an oracle number on screen is not the same as understanding how it was produced.
Leverage makes execution risk more expensive. Entropy's margin guide explains how collateral is allocated, while its liquidation and ADL pages cover what happens when a position runs out of room. Some markets support isolated margin only. TP/SL and slippage limits help define an order, but the order book and the market's rules still determine the outcome.
Holding through a major event calls for a different kind of reading. Pre-IPO contracts have rules for a listing or a no-IPO outcome. Stock perps have separate treatment for acquisitions, delistings, and splits. A familiar company name does not tell you how its derivative will be settled.
Access and account safety deserve a check before funding. Entropy's security page names entropy.io as its official domain, describes Privy authentication, and says the platform never asks for a seed phrase or private key. Its terms warn that users can lose their entire collateral and that access may be restricted. Public pages loaded in a session using a Vietnamese IP, but Entropy's restricted-jurisdiction list and account checks still determine who can use the service.
A closer look at Anthropic's market
ANTH illustrates why the contract specification matters. On October 27, the trading page showed ANTH-USDC; on October 28, the header showed ANT-USDC, while the chart and Hyperliquid metadata still identified the market as io:ANTH. The new label resembles ANT, the stock symbol Anthropic plans to use if it lists. Yet Entropy's pre-IPO specification is clear: this is a cash-settled contract on implied market capitalization, not a share or an IPO allocation.
The live form and our October 28 metadata snapshot showed a 15× maximum for ANTH, while Entropy's asset directory still listed 6×. That gap matters more to a trader than the choice of ticker label. The practical habit is to read the rules for the exact market and check the current order form before placing a trade; a number in an older article or documentation page may no longer match the venue.
What Entropy does well, and where it stumbles
The appeal is straightforward: one interface opens a window onto several markets that traditional stock brokers do not offer as 24/7 perps. The learning curve is also real. Traders have to understand the instrument, its price source, and the consequences of leverage; finding the Place Order button is the easy part.
Entropy.io vs. the Competition
trade[XYZ] is another HIP-3 deployer covering real-world markets on Hyperliquid. Ostium pursues a similar audience through a different setup on Arbitrum. The meaningful differences are in market coverage, pricing and execution design, and what a position costs to hold.
For a pre-IPO trade on Hyperliquid, Entropy and trade[XYZ] deserve a contract-by-contract comparison. Their prices should not be read as interchangeable: Entropy explicitly quotes implied market capitalization, while trade[XYZ] describes a different reference and post-listing transition. For FX or commodities, trade[XYZ] and Ostium document broader coverage than the Entropy markets examined here. Ostium's RFQ and rollover model also makes a simple maker/taker fee comparison misleading. The better choice depends on the exact market, its price source, and the total cost of entering and holding the position.
Verdict
Entropy.io is a capable public trading desk for several kinds of USDC-margined perpetuals. We found it easy to browse markets, inspect the order book, and prepare an order without signing in. Its biggest weakness is the distance between a polished trade screen and the contract knowledge needed to use it well. The ANTH leverage discrepancy adds a practical reason to verify live parameters instead of relying on a static asset page. The interface earns a positive assessment for discovery and trading controls; execution quality, actual account fees, and withdrawals remain questions for a funded-account test.
Frequently Asked Questions
1. Does Entropy.io sell Anthropic or OpenAI shares?
No. Its pre-IPO perpetuals are cash-settled derivatives on implied valuation. A position carries no share ownership, dividend, voting right, or IPO allocation.
2. What kinds of markets does Entropy offer?
Entropy documents pre-IPO, stock, index/ETF, and pre-listing contracts. Its selector also displays other Hyperliquid markets, which are not all Entropy deployments.
3. Do I need an account to see prices and order books?
No account was needed to open the public charts, order books, market selector, or Leaderboard in our session. Account features lead to email or wallet sign-in; Entropy's quickstart explains what follows.
4. What are Entropy's trading fees?
The published HIP-3 base rates are 0.030% maker and 0.090% taker. Tiers, growth mode, and rebates can change the effective rate. Funding, spread, and slippage also affect a position's total cost.
