Hyperliquid activated HIP-4 Outcome Markets on mainnet on May 2, 2026, adding fully collateralized onchain prediction markets to the same trading account users already use for spot and perpetuals. The launch puts Hyperliquid directly into competition with prediction market platforms such as Polymarket and Kalshi, with the protocol leaning on a notably aggressive fee model: zero fees to open or mint outcome positions.
The first live contracts are daily BTC threshold binary markets, giving traders a way to take YES or NO positions on recurring bitcoin price outcomes. By embedding these products inside Hyperliquid’s native trading stack rather than outsourcing them to a separate app layer, the protocol is attempting to turn prediction markets into just another instrument within a unified onchain trading environment.
A New Primitive Separate From HIP-3
HIP-4 is distinct from HIP-3, which launched on mainnet on October 13, 2025 and focused on builder-deployed perpetual futures tied to equities, commodities, foreign exchange, and other real-world assets. While HIP-3 is built around continuous price discovery and the needs of leveraged perpetual trading, HIP-4 introduces a different contract primitive designed specifically for event-based markets.
That difference is more than cosmetic. Perpetuals under HIP-3 depend on continuously updated oracle feeds and are built to support ongoing trading with mechanisms such as funding and liquidation. Event markets, by contrast, revolve around discrete outcomes that resolve at expiry. Elections, economic releases, sports results, and threshold-based crypto events do not fit neatly into a structure optimized for smooth price updates and leveraged exposure.
HIP-4 therefore uses fixed-range settlement. Binary and multi-outcome contracts settle to exactly 0 or 1 at expiration, depending on the outcome supplied by an authorized oracle source. There is no ongoing funding rate and no liquidation engine, making the product structurally different from the perpetuals Hyperliquid users may already know.
How HIP-4 Markets Work
In HIP-4, traders buy YES or NO exposure as tokens representing the market-implied probability of an event. Prices trade continuously between 0.001 and 0.999 before expiry. The payoff is straightforward: if a trader buys YES at 0.60 USDH and the event occurs, the contract settles at 1, generating a 0.40 gain per contract. If the event does not occur, the position settles at 0 and the trader loses the 0.60 paid to enter.
All positions are fully collateralized in USDH, Hyperliquid’s native stablecoin. Because positions are fully funded rather than leveraged, the product does not expose traders to liquidation risk. Hyperliquid also ties this design back to its broader protocol economics, arguing that settlement demand increases USDH usage and feeds into the existing mechanics that support HYPE buybacks.
Fee Structure Built to Pull Volume
The fee model is one of the clearest signals that Hyperliquid wants to win market share in prediction markets rather than merely experiment with the category. According to the launch details, users pay no fee when opening or minting an outcome position. Fees are only charged when traders close, burn, or settle a position.
For makers, the design is also unusual. Orders in outcome markets that might ordinarily qualify for rebates instead receive neither a rebate nor a charge, effectively operating at zero. At the same time, staking-aligned fee discounts still apply, including the possibility of a 20% reduction in taker fees under the protocol’s existing structure.
This combination is clearly meant to make HIP-4 competitive with established players in the event trading segment. Rather than relying solely on decentralization or composability as selling points, Hyperliquid is pairing onchain settlement with lower friction for trade entry.
Initial Markets and Expansion Plans
At launch, the first markets are curated and validator-deployed. The initial live products focus on recurring daily BTC price threshold events that reset at 2 a.m. Hyperliquid said future categories are expected to include politics, sports, macroeconomic releases, crypto-native events, and entertainment.
That staged rollout mirrors the protocol’s broader product development strategy: begin with more controlled market creation, then gradually move toward a broader builder ecosystem once the market structure has proven stable in production.
Permissionless Deployment Comes Later
In a later phase, builders will be able to deploy their own outcome markets in a permissionless manner, but only by posting meaningful economic stake. Each market slot requires 1,000,000 HYPE to be staked. That stake is slashable and can be burned if validators determine that the deployer manipulated the oracle, introduced invalid state transitions, or caused prolonged downtime.
One staked slot can support rolling and recurring markets, and the slot can be recycled after settlement. The design attempts to balance openness with accountability: builders can eventually launch markets without centralized approval, but they must put substantial value at risk if they fail to maintain market integrity.
Auction Design and Matching Engine
Each new market begins with an approximately 15-minute single-price clearing auction. During that window, users submit limit orders, but no execution occurs until the auction clears at the price that maximizes matched volume. Any unfilled orders then roll into continuous trading on the same central limit order book that powers Hyperliquid’s spot and perpetual venues.
This matters because HIP-4 is not being launched as a separate system. The architecture runs natively inside Hypercore, sharing the same matching engine, order types, and the platform’s stated throughput of roughly 200,000 orders per second. In practical terms, traders are not switching into an isolated prediction market app; they are using a new contract type within the same high-performance exchange environment.
Unified Account Experience
Outcome positions live inside the same wallet as a trader’s spot and perpetual holdings and are incorporated into unified portfolio margin. That integration could become a major differentiator if Hyperliquid succeeds in turning event contracts into a natural extension of broader trading activity.
The protocol also said that, once permissionless deployment matures, volume and open interest from outcome markets will count toward protocol-wide fee tiers. That creates an incentive loop where active prediction market traders may also qualify for lower rates in perpetuals through the same account, reinforcing the idea of a single trading identity across products.
Frontend Support Already Emerging
Several frontends are already integrating the new product set. Hyperliquid named Outcomexyz and Stratium among the interfaces supporting HIP-4, with Stratium presenting outcome markets alongside HIP-3 perpetuals in one interface. Dedicated analytics and tracking dashboards, including the loris.tools suite, are also expected to add HIP-4 data in the near future.
That ecosystem support may prove important. Prediction markets often depend not only on contract design, but also on discoverability, market curation, and clear analytics. If HIP-4 can tap into the existing user flow and liquidity habits of Hyperliquid traders, it may gain traction faster than a standalone venue trying to build both infrastructure and audience from scratch.
Why the Launch Matters
Hyperliquid’s HIP-4 launch represents a notable attempt to bring event trading into the same onchain execution stack as spot and derivatives. The product combines full collateralization, zero-fee entry, a central limit order book, and eventual permissionless market creation backed by HYPE staking. Whether that is enough to dislodge incumbent prediction market platforms remains to be seen, but the strategy is clear: compete on market structure, user experience, and account-level integration rather than on novelty alone.
For now, the protocol has started with BTC daily binaries and a validator-managed launch phase. If liquidity builds and the permissionless deployment phase arrives smoothly, HIP-4 could become one of the most consequential expansions of Hyperliquid’s trading stack beyond perpetual futures.
