The approach removes the need for third-party oracle systems. Hyperliquid developer Yaugourt
described the significance on X: "Hyperliquid just removed the need for external oracles on prediction markets. The validator set itself is now the oracle." He added that real-world event resolution is now a native chain function. This is a structural departure from how other major prediction platforms handle resolution.
Polymarket uses the Universal Market Access Optimistic Oracle, which allows participants to propose and challenge market outcomes before they are finalized. Kalshi operates under a more centralized model, with its internal team reviewing evidence and determining resolutions directly. Hyperliquid's validator-based system instead distributes that responsibility across the network's node operators.
Outcome markets on Hyperliquid are fully collateralized contracts that settle within a fixed range. They do not involve leverage or liquidations. HIP-4 was formally activated on May 2, when the team announced the initial limited-feature mainnet release for outcome markets. The update moves that feature into fuller operation with validator governance now live.
Hyperliquid launched its first active off-chain event market, titled "May CPI year-over-year," which had accumulated $11,268 in trading volume by the time of reporting. The contract is live on the platform's trading page and represents the first real deployment of the validator-governed settlement system against an actual macroeconomic data event.
HYPE was down 3.5% over the past 24 hours, trading at $60.25, while remaining up 26.8% over the prior seven days. The token's weekly gain reflects sustained market interest in the platform even as the broader
crypto market held in a narrow range during the same period.
