What Is HIP-4? Hyperliquid Outcome Markets Explained
HIP-4 brings outcome-market primitives to Hyperliquid. Searchers often compare it with Polymarket, but the key idea is a bounded payoff contract that settles based on a defined outcome.
Direct answer
HIP-4 is Hyperliquid's outcome-market framework. Instead of a perpetual contract with funding and liquidation mechanics, an outcome market is built around a defined event or condition and a bounded payoff. It can resemble a prediction market in search results, but the contract rules, settlement source, collateral, and venue access decide the actual risk.
What makes outcomes different
- The payoff is bounded by the contract terms.
- There is usually a defined expiry or settlement event.
- The market price can be read as an implied probability only after considering fees, spreads, and settlement risk.
- There is no simple one-to-one mapping between outcome markets and vanilla options.
Live HIP-4 contract board
Public Hyperliquid contract metadata and raw Yes/No side mids. A side mid is a market price, not a verified probability or forecast.
Resolution rules require a separate check
The public response currently provides class, target or thresholds, expiry, side labels, and mids for 199 contracts, but not the full oracle and comparison rule. HypeBasis shows those raw fields while withholding verified-probability labels and contract-specific EV links.
Standalone binary contracts
Each row uses the target, expiry, side labels, and mids returned for the current contract id.
