What is HIP - 4 Upgrade and its Special Features to Watch out in 2026 ?

# What is HIP - 4 ? **HIP-4 (Hyperliquid Improvement Proposal 4)** is a major protocol upgrade that enables **outcome markets** on Hyperliquid. Instead of trading only perpetual futures, users can trade fully collateralized YES/NO contracts tied to **real-world events**, **cryptocurrency price targets**, **economic indicators**, or other verifiable outcomes. Once an event is resolved, each contract settles to a fixed outcome according to the protocol’s predefined rules. By bringing **prediction market functionality directly onto Hyperliquid’s high-performance Layer 1 blockchain**, Hyperliquid’s HIP-4 expands the platform beyond traditional crypto trading into decentralized prediction markets. **Key Features of the Hyperliquid HIP-4** * Outcome Contracts  * USDH-Based Settlement * Fully Collateralized & Risk-Defined Trading * CEX-Like Trading Experience * Collective Market Intelligence * Unified Trading Infrastructure * Binary Settlement Model * HyperCore Integration * Isolated Margin Framework * Opening Price Auction * Transparent Resolution Framework * Permissionless Market Creation * Customizable Fee Sharing * Composable Trading Strategies Hyperliquid HIP-4 proves that the next phase of DeFi isn’t about launching more products — it’s about unlocking entirely new markets. It’s more about expanding opportunities. By integrating prediction markets into its ecosystem, Hyperliquid is creating a unified platform where traders can access multiple market opportunities without leaving the protocol.
