Hyperliquid has launched validator-settled prediction markets through its HIP-4 upgrade, transforming its validator set into an on-chain oracle for real-world events. This upgrade allows Hyperliquid to support outcome markets for off-chain events without relying on external oracles. Validators assess market rules and quality, ensuring market resolution remains within Hyperliquid's network. The same validators that secure over $3 billion in deposits now serve as the source of truth for event outcomes. The HIP-4 upgrade distinguishes Hyperliquid from competitors like Polymarket and Kalshi by integrating market settlement directly into its blockchain operations. Outcome contracts are fully collateralized and settle within a fixed range, allowing traders to hold positions in both outcome markets and perpetual contracts within the same account. Hyperliquid's first off-chain event market, launched on May 2, showed $11,268 in volume, demonstrating the potential for pricing public events like economic data releases.
