Short answer: HIP-3 is the Hyperliquid standard that lets independent operators deploy their own perpetual futures markets on top of Hyperliquid’s infrastructure — which is how venues like trade.xyz now offer 24/7 perpetual contracts on stocks like Tesla, Nvidia, and Apple, plus indices like the S&P 500, with the same no-KYC, self-custody access as the rest of Hyperliquid. It’s not tokenized share ownership, it’s price exposure through an on-chain perpetual contract, available every hour of every day, including weekends, without a broker in the middle.
Traditional markets close. Your interest in them doesn’t
The stock market is open roughly 6.5 hours a day, five days a week, and closed for every major event that happens outside that window. Earnings drop after the bell, geopolitical news breaks over the weekend, and by the time Monday’s open rolls around, the price has already moved without you. On top of that, trading US equities as a non-US resident typically means opening an account with a broker, handing over identity documents, and accepting whatever hours and access restrictions that broker’s jurisdiction imposes.
HIP-3 removes both constraints. It’s a Hyperliquid standard that lets independent, HYPE-collateralized operators launch their own perpetual futures markets — including markets that track equities and indices — and those markets never close.
What HIP-3 actually is
Hyperliquid’s core protocol lists its own perpetuals (BTC, ETH, and dozens of other crypto assets) through validator governance. HIP-3 opens that up: any operator willing to stake a minimum of 500,000 HYPE can deploy their own perpetual DEX, with its own markets, its own front-end, and its own fee revenue, on top of Hyperliquid’s execution layer. The stake acts as a security bond — up to 100% can be slashed if the operator manipulates pricing or acts maliciously — which is the mechanism that keeps a permissionless system honest without needing a central listing committee.
The most visible result of this is trade.xyz, a HIP-3 venue offering perpetual contracts on equities like Tesla, Apple, and Nvidia, plus synthetic indices such as a Nasdaq-100 tracker and an S&P 500 perpetual licensed from S&P Dow Jones — all tradable 24/7, weekends included. As of August 2026, aggregate open interest across HIP-3 markets reached $3.6 billion, the large majority of it on trade.xyz.
What you’re actually trading — and what you’re not
It’s a perpetual contract, not the stock. A Tesla perp on HIP-3 tracks Tesla’s price through an oracle feed. You’re taking a leveraged long or short position on that price, not buying shares — no dividends, no shareholder vote, no share certificate. Be clear-eyed about that distinction before trading it.
No broker, no KYC for standard access. Same as the rest of Hyperliquid: connect a self-custody wallet and trade. No brokerage account, no jurisdiction-based access restriction layered on top by a third-party institution.
Markets never close. Earnings after hours, weekend news, a Monday gap you’d otherwise have to wait for — HIP-3 markets keep trading around the clock, so the price moves when the news does, not when an exchange happens to be open.
Fees vary by market. Builders set their own fee scale per market — most run at a base tier of 0.09% taker / 0.03% maker, with the operator keeping roughly half. Check the specific venue’s live fee schedule before sizing a trade; it isn’t uniform across every HIP-3 market the way core Hyperliquid perps are.
The real risk you’re taking on
Because HIP-3 markets are operator-managed rather than protocol-managed, they carry a different risk profile than Hyperliquid’s native perps. Each market depends on that operator’s own oracle feeds and liquidity provisioning — if either fails or thins out, fills can move against you. Positions on most HIP-3 markets are isolated-margin only, meaning each position is margined on its own rather than pooled with the rest of your account, so size and manage each one deliberately. And unlike core Hyperliquid markets, an operator can retire their own venue without a full validator vote. None of this makes HIP-3 markets untrustworthy — the HYPE stake and slashing mechanism exist precisely to keep operators honest — but it does mean doing your own check on a specific venue’s track record before trading size on it, the same diligence you’d apply to any new platform.
One account, every Hyperliquid market
HIP-3 markets run on the same Hyperliquid account and wallet as everything else on the platform — perps, spot, staking. There’s no separate sign-up for stock perpetuals specifically; if you already have a Hyperliquid account, you’re one click from trade.xyz or any other HIP-3 venue built on top of it.
Summary
HIP-3 turns Hyperliquid into infrastructure other operators can build their own perpetual markets on top of — which is how stock and index perpetuals with 24/7 access, no broker, and no KYC now exist on-chain. It’s price exposure through a perpetual contract, not real share ownership, and it carries operator-specific risk that core Hyperliquid perps don’t. For traders who’ve felt the limits of market hours and brokerage gatekeeping, it’s a genuinely different way to get exposure to the assets that move the news cycle, on your own schedule, through the same self-custody account you’d use for anything else on Hyperliquid.
