The standard framing of US equities is that they trade about 32.5 hours a week and the rest is dead time: pre-market thinness, after-hours prints on a handful of names, nothing on weekends. The framing is half right. The price of $NVDA now moves 168 hours a week on a market where it is the single largest contract, and it does so on an order book anyone with a wallet can read. The stock is closed; the price of the stock is not.
That market is xyz, a set of perpetual futures on equities, indices and commodities deployed on Hyperliquid. This piece is the mechanical explainer: what a stock perp is and is not, how a price is produced for a stock whose exchange is shut, what the position costs, where the risk sits, and who cannot use it. The live board of every instrument on this site's map that carries one is at /hyperliquid.
The TL;DR. A stock perp is a synthetic exposure to a share price, settled in USDC, that never closes. On Hyperliquid the equity perps live on
xyz, a third-party-deployed dex that did USD 2.76B a day across 103 markets when this desk measured it, with NVDA and SK Hynix as its two largest contracts. The perps track their underlying within about 0.3 % during market hours, and the interesting part, and the risky part, is what happens in the other 135 hours of the week. Fees are low, leverage is capped when the stock market is closed, US persons are excluded, and the collateral is yours to lose.
What xyz is, measured
Hyperliquid's own perp dex lists crypto. Under HIP-3, its builder-deployed-perps framework, third parties can stake HYPE and deploy their own markets with their own oracle, and xyz, operated by Trade.xyz, is the one that matters for anyone who trades equities. When this desk measured the venue on 2026-08-28: 10 HIP-3 sub-dexes existed, and xyz did 43 times the volume of the next one. It carried 103 markets, USD 2.76B of 24-hour volume and USD 3.43B of open interest. The top five markets were NVDA (USD 379M a day), SK Hynix (USD 304M), the XYZ100 index, silver, and the S&P 500.
Two things about that list are worth noticing. First, the largest stock perp market in crypto is not a meme; it is the most-traded share on earth. Second, 48 % of xyz volume, USD 1.33B a day across 26 markets, is the AI, memory and semiconductor complex this site maps in its semiconductors and memory bubbles. Of the instruments on QuantAbundance's map, 68 have a liquid perp (more than USD 100k a day) on xyz, which is why their /stocks pages carry a live perp mark and funding rate alongside the exchange close.
A perp is not a share
A perpetual future is a contract that tracks a reference price with no expiry, kept honest by funding: when the perp trades above the reference, longs pay shorts every hour; when it trades below, shorts pay longs. Hyperliquid's version is margined and settled in USDC. That is the whole instrument, and it implies everything a stock perp does not carry:
- No dividend, no vote, no claim. A long NVDA perp pays nothing on the ex-date, though the deployer may adjust the reference for corporate actions on its own terms.
- No shares change hands. Nobody borrows stock to short it, which is why a stock that is hard to borrow on a prime broker can be shorted here at the same fee as a long.
- A counterparty that is a book, not a broker. The other side is whoever is on the book, and the clearing is the protocol's liquidation engine, not a clearing house.
- A price that is produced, not discovered, when the underlying is closed. This is the part that deserves its own section.
How a closed market gets a price
Trade.xyz's relayers compute and push three inputs roughly every three seconds: an oracle price, a mark price and an external reference. Hyperliquid's own price feed contributes one component of the mark; the deployer supplies the rest. While the underlying exchange is open, the oracle is the live stock price and the perp tracks it tightly. This desk measured the ratio of perp mark to underlying on six names during market hours: NVDA 1.001, $MU 0.998, $AAPL 1.000, $AMD 1.003, $TSM 1.002, $META 0.999. Same prices, to within a third of a percent.
When the exchange closes, the deployer's oracle switches to a closed-market mechanism and the perp becomes the only place the price is being formed. Three consequences follow:
-
Funding does the anchoring. Every hour the perp is pulled back toward the reference through payments between longs and shorts. Positive funding means the leveraged crowd is paying to be long that name right now, which is also why this site shows the funding rate on each covered
/stockspage: it is a live read on positioning that the stock market itself cannot offer at 3 a.m. - Leverage is capped overnight and over weekends. Because the protocol is not discovering the underlying price in those hours, the deployer imposes tighter limits when oracle data is thin. The same position that ran at high leverage on Wednesday afternoon may not be openable at that size on Saturday.
- The open gap is already in the perp. By the time the stock prints its first trade on Monday, the perp has been pricing the weekend's news for 65 hours. The stock market "gaps"; the perp has simply moved.
The failure mode is real and has already happened. In 2026 an oracle anomaly on the SK Hynix market triggered roughly USD 57M of liquidations in minutes, and Hyperliquid published an explanation afterwards. A stock perp can diverge from its stock because of funding, thin liquidity, an oracle update, a trading halt, a corporate action or a deployer setting. Anyone treating the perp as the stock with longer hours has skipped this section.
What it costs
- Trading fees. Hyperliquid's base perp schedule at the time of writing is 0.045 % taker and 0.015 % maker, reduced by 14-day volume tiers (the first tier starts at USD 5M), by HYPE staking (5 % to 40 % off) and by a referral discount of 4 % on the first USD 25M of volume. The discounts stack multiplicatively. The full schedule and what the referral is worth in dollars is in Hyperliquid fees, explained. On HIP-3 markets the deployer keeps a share of the fee; the trader's rate is what the venue shows.
- Funding. Not a fee but a transfer, paid or received hourly. On a heavily long name it is a real carry cost for a long held through the weekend.
- Deposits and withdrawals. Deposits are native USDC on Arbitrum only, minimum 5 USDC. Withdrawals back to Arbitrum cost a flat 1 USDC. The European on-ramp is mapped in Funding Hyperliquid from Europe; the exit rail, which is the harder half, in Getting money off Hyperliquid.
- Leverage. The fastest way to lose money in any stack this site describes. A perp position is marked continuously and liquidated by rule, at 3 a.m. as readily as at 3 p.m. Size as if the position will be wrong.
Who can use it, and who cannot
There is no KYC: connect a wallet and the book is open. That is a feature or a liability depending entirely on where you sit and what your own compliance position is. Hyperliquid's terms exclude US persons and residents of Ontario, and the app geo-blocks US IP addresses; sanctioned jurisdictions are excluded as well. The exclusion runs on IP and on the terms rather than on documents, which does not make it less of an exclusion. A European trader is inside the perimeter; a US one is not, whatever the routing.
Self-custody is the other half of the eligibility question. There is no password reset and no desk that can reverse a signature. A lost key is a lost balance. If that sentence produces discomfort, the discomfort is the correct reading and this is not the venue.
How this desk uses it
Three ways, none of them a strategy. First, as a price source: the perp mark and funding rate appear on every covered /stocks page and on the 24/7 board, which is the only price feed on this site with no redistribution constraint attached (the exchange feeds arrive under contracts that forbid it). Second, as a positioning signal: hourly funding on NVDA or MU is a direct measure of what the leveraged crowd is paying to hold a side, updated while the stock market sleeps. Third, as a venue for the desk's own perp flow, alongside IBKR for the shares themselves; the honest record of the one Hyperliquid strategy this desk built and killed is on the stack page.
What to watch
-
xyzmarket count and depth. 103 markets when measured; the list grows and the long tail is thin. Volume concentrates in a few names, and a perp with USD 100k a day is not the same instrument as NVDA's USD 379M. - Oracle incidents. Each one resets what "tracks the underlying" means in practice. The SK Hynix episode is the reference case.
- Closed-hours leverage rules. The cap is the deployer's setting and can change; it decides what a weekend position can be.
- Competing deployers. HIP-3 lets anyone with the stake list equities; a second liquid equity dex would split the book and change the funding picture.
- Regulation of synthetic equities. A perp on a US stock, offered without KYC to non-US persons, sits in a space regulators have not finished describing.
Disclosure, so the incentive is on the table: the Hyperliquid link on this site is a referral link. If a reader opens an account through it, this desk earns a share of the fees that reader pays, and the reader's own fee schedule is reduced by the referral discount, not increased. Applying without the link costs nothing and changes nothing except that discount. This desk trades on the venue for its own account, and that is the reason it appears here; the referral is the incentive, and it is stated rather than hidden.
