Hyperliquid disclosed its HIP-4 upgrade, introducing a new product primitive called Outcome Contracts—also referred to as “Event Perpetuals”—and shipping an initial testnet build on its HyperCore engine. The update is positioned as a way to bring prediction-market style trading onto the platform in a more structured, risk-contained format, and it coincided with an immediate uptick in market attention for the HYPE token.
At its core, HIP-4 pitches Outcome Contracts as objective, bounded instruments designed to eliminate liquidation dynamics and broaden event-driven trading beyond casual “social betting.” The proposal argues that by constraining exposure and anchoring settlement to verifiable sources, the product can support more institutional-style hedging and bespoke risk transfer.
HyperCore will support outcome trading (HIP-4). Outcomes are fully collateralized contracts that settle within a fixed range. They are a general-purpose primitive that are useful for applications such as prediction markets and bounded options-like instruments. There has been…

A cleaner wrapper for event risk
HIP-4 defines Outcome Contracts as fully collateralized, time-bound contracts that settle inside a predetermined price band on a preset date. In practice, that means participants post the maximum possible loss up front, and the contract resolves to a value within a fixed range at settlement, rather than floating indefinitely like a standard perpetual.
The practical design goal is to make event exposure behave more like a controlled instrument than a levered position that can be forcibly unwound mid-trade. Compared with margin-based perpetuals that typically rely on leverage, funding mechanics, and liquidation pathways, the Outcome Contract framing shifts the user experience toward explicit downside caps and event-specific outcomes, with room for non-linear payoff profiles.
The proposal also highlights a platform strategy: keep the primitive general-purpose so third parties can permissionlessly build prediction markets or bounded, option-like structures on top of it. That builder-first posture is meant to turn HIP-4 into reusable market infrastructure rather than a single flagship market.
What’s driving attention and what still needs to land
The announcement was met with a visible market response, with some outlets reporting the HYPE token gained more than 9% in the hours after HIP-4 surfaced. Hyperliquid has also indicated that “canonical” markets are intended to follow once the work around objective settlement sources is complete, while the testnet phase continues.
Sam Ruskin of Messari captured the thesis succinctly, arguing that “Outcome Contracts solve the ‘oracle problem’ and eliminate liquidation risk,” which is why the concept can be more attractive for professional liquidity. The underlying bet is straightforward: if settlement is robust and the exposure profile is clean, market makers and institutional desks may be more willing to treat event outcomes as a legitimate hedgeable surface.
Execution risk remains concentrated in two areas: the strength of the settlement-oracle design and whether third-party builders actually create compelling markets at scale. Even with full collateralization and integrity-focused settlement language, prediction-market products can still invite legal and compliance scrutiny depending on jurisdiction and participant profile.
