Hyperliquid HIP-4: Outcome Markets
Hyperliquid HIP-4 introduces fully collateralized outcome markets directly on the Hyperliquid blockchain, allowing users to trade YES/NO contracts tied to real-world events and market outcomes. Unlike traditional leveraged derivatives, these markets settle within a fixed range, removing liquidation risk while still offering real-time probability pricing. Built natively into HyperCore, HIP-4 combines prediction market functionality with Hyperliquid’s high-speed trading infrastructure, shared liquidity, and unified margin system.
Short history
HIP-4 launched as Hyperliquid’s native framework for fully collateralized outcome and prediction markets.
Introduced through Hyperliquid Improvement Proposal 4 (HIP-4), outcome markets expanded Hyperliquid beyond perpetual futures into fully collateralized YES/NO event contracts. Unlike standalone prediction market platforms, HIP-4 is built directly into the HyperCore trading engine, sharing liquidity, order books, and portfolio margin with spot and perp markets. The first rollout focused on recurring BTC and HYPE outcome markets, with broader event markets planned over time.
