Prediction markets just got a new competitor, and it’s one that already knows how to handle serious trading volume. Hyperliquid launched HIP-4 on its mainnet on May 2, 2026, introducing binary outcome contracts to a platform that has spent the past year quietly becoming one of crypto’s most important derivatives venues.
The upgrade is a bigger deal than a routine protocol patch. HIP-4 lets anyone create a market on a real-world event outcome, fully permissionless, without needing Hyperliquid’s approval. That’s the same philosophy that made HIP-3’s permissionless perpetual trading such a hit, applied now to the prediction market vertical that Polymarket and Kalshi have largely owned.
What HIP-4 actually does
Binary outcome markets settle to either 0 or 1. In English: you’re trading on whether something happens or doesn’t, and when the event resolves, every contract pays out accordingly.
These contracts are fully collateralized, meaning the money to cover every possible outcome is locked in from the start.
