Hyperliquid activated HIP-4 Outcome Markets, bringing on-chain prediction contracts directly into same account traders use for trading. The first live contracts cover recurring daily BTC price threshold events, opening or minting a position carries zero fees, a model designed to pull volume directly from Polymarket and Kalshi.

Within six hours of launch, Hyperliquid surpassed Polymarket's volume on the equivalent BTC Up/Down daily market — 89,253 shares traded on Hyperliquid vs. 79,500 on Polymarket.

Unlike standalone prediction platforms, HIP-4 runs inside Hyperliquid's unified margin account, allowing traders to hold outcome positions alongside perps and spot without moving collateral or switching interfaces.
