Hyperliquid has officially activated HIP-4 Outcome Markets on mainnet, adding a new prediction-market primitive to the same trading environment where users already manage perpetual futures and spot positions. The launch, which went live on May 2, 2026, marks a meaningful expansion of the protocol’s product suite and places Hyperliquid in more direct competition with established prediction-market platforms such as Polymarket and Kalshi.
The first live markets are based on recurring daily BTC price threshold events, giving traders a binary structure for expressing a view on short-term outcomes. Instead of requiring users to move to a separate platform, Hyperliquid is positioning prediction contracts inside its existing account architecture, allowing traders to hold event positions alongside their spot and perps exposure.
A Different Primitive From HIP-3
HIP-4 is distinct from HIP-3, which previously introduced builder-deployed perpetual futures for assets such as stocks, commodities, foreign exchange, and other real-world asset references. While HIP-3 was designed for continuous leveraged trading supported by ongoing oracle updates, HIP-4 is built specifically for binary and multi-outcome contracts that resolve to exactly 0 or 1 at expiry.
That design difference is important. Perpetual markets depend on continuously updated pricing and mechanisms such as funding rates and liquidation logic. Outcome markets do not. Under HIP-4, contracts use fixed-range settlement and avoid the need for a liquidation engine entirely. This makes the structure better suited for discrete events such as election results, macroeconomic releases, sports outcomes, or crypto-specific developments.
Users buy YES or NO positions that trade between 0.001 and 0.999 during continuous trading. At settlement, an authorized oracle source determines the final result. If a trader buys YES at 0.60 USDH and the event occurs, the position settles at 1, implying a 0.40 gain per contract. If the event does not occur, the trader loses the 0.60 paid to enter.
Fully Collateralized With USDH
All HIP-4 positions are fully collateralized in USDH, Hyperliquid’s native stablecoin. Because of that design, the new market type does not introduce liquidation risk in the way margin-based leveraged products do. The collateral model also reinforces Hyperliquid’s broader protocol economics: settlement demand increases USDH usage, and according to the report, that demand feeds into the protocol’s existing HYPE buyback mechanics.
The integrated setup may appeal to active traders who want to manage multiple strategies inside one account. Outcome positions are held in the same wallet environment as perps and spot balances, and they are included in Hyperliquid’s unified portfolio margin framework. This allows the protocol to present prediction markets not as a standalone side product, but as another native market format within its trading stack.
Zero Fees to Open Positions
One of the clearest competitive signals in the HIP-4 rollout is its pricing model. Hyperliquid says there are zero fees to open or mint an outcome position. Fees are charged only when users close, burn, or settle a position. In addition, makers on outcome orders, who might normally receive rebates in other market structures, instead face a zero-fee schedule here.
Staking-aligned fee discounts still apply, including a potential 20% reduction in taker fees. The result is a fee structure that appears explicitly designed to attract prediction-market volume away from incumbent venues. In practical terms, Hyperliquid is using low-friction access and account-level integration as its opening argument against specialized competitors.
How Markets Open and Trade
Each new HIP-4 market begins with an approximately 15-minute single-price clearing auction. During that auction window, users can submit limit orders, but no trades execute until the auction clears at the price that maximizes matched volume. Any remaining orders then continue into standard continuous trading on the same central limit order book infrastructure used by Hypercore’s spot and perpetual markets.
This architecture matters because HIP-4 is not built as a separate application layer with isolated liquidity mechanics. It runs natively inside Hypercore, sharing the same matching engine, order types, and the protocol’s stated throughput of roughly 200,000 orders per second. For traders, that means prediction markets are being delivered with the same performance assumptions as the rest of Hyperliquid’s exchange environment.
Validator-Curated Today, Permissionless Later
At launch, outcome markets are curated and deployed by validators. The initial focus is on repeatable event contracts such as daily BTC threshold markets, which reset at 2 a.m. Planned category expansion includes politics, sports, macro data releases, crypto events, and entertainment.
Over time, Hyperliquid intends to move toward permissionless builder deployment, following a phased path similar to HIP-3. To deploy an outcome market, builders will need to stake 1,000,000 HYPE per slot. That stake is slashable: if validators determine that a deployer manipulated an oracle, introduced invalid state transitions, or caused prolonged downtime, the staked HYPE can be burned.
One staked slot can support rolling and recurring markets, with the slot becoming reusable after settlement. This structure is designed to create economic accountability for market creators while still offering an eventual route to broader market participation and decentralized expansion.
Ecosystem Integration and Competitive Positioning
Several frontends are already integrating the new market type. The report names Outcomexyz and Stratium among early interfaces, with Stratium reportedly placing HIP-4 outcome markets alongside HIP-3 perpetuals in a unified interface. Additional tracking dashboards, including tools in the loris.tools suite, are expected to add HIP-4 coverage as the product matures.
Another strategic detail is that volume and open interest from outcome markets count toward protocol-wide fee tiers. That means an active prediction-market participant could potentially qualify for lower trading costs on perpetuals through the same account. In effect, Hyperliquid is using account unification and fee-tier portability to turn prediction trading into a contributor to its larger exchange ecosystem.
Viewed more broadly, HIP-4 represents Hyperliquid’s attempt to make prediction markets a native component of onchain trading infrastructure rather than a separate vertical. By combining full collateralization, zero opening fees, centralized-order-book style execution, and a future permissionless deployment path, the protocol is making a direct push into a category where user experience, liquidity, and trust in settlement are all critical. Whether that will be enough to pull sustained volume from established rivals remains to be seen, but the launch clearly signals that Hyperliquid wants a serious share of the onchain prediction-market market.
