HyperCore Proposal HIP-4: Building Native "Outcome Transaction" Infrastructure for On-chain Prediction Markets

February 2nd, Hyperliquid officials announced via social media that HyperCore will support Outcome Transactions (HIP-4). An outcome is a fully collateralized contract with a settlement price constrained to a fixed range. A generic, foundational trading building block, it applies to prediction markets and bounded option-like instruments. User demand in these two areas is already substantial, and developers are expected to build innovative applications as well. Outcome Transactions introduce a non-linear payoff structure, forward contracts, and a form of derivative trading free of leverage or forced liquidation. This foundational element expands HyperCore’s expressive power and can integrate with other core elements (such as Portfolio Margin and HyperEVM). The Outcome Transactions feature remains in development and is currently being tested on the testnet. A standard market tied to an objective settlement source will launch once technical development concludes, with pricing in USDH. After gathering user feedback, this infrastructure will expand to a permissionless open deployment model.
