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.

Outcome markets can look like options or prediction markets, but the exact payoff, collateral, settlement source, and market rules decide the real risk.

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.

Outcome market data

This uses public Hyperliquid outcome data and available side prices. Treat implied probability as market-price context, not a forecast or trade recommendation. Recent-change context appears only when enough saved price history exists for the same side.

Risk notice
Outcome markets are high-risk event contracts. A market price is not a verified probability, the full cost can be lost, and resolution, settlement, liquidity, fees, and eligibility rules may alter the real risk.
