[Hyperliquid Mainnet Launches Outcome Markets, Introducing the First Daily BTC Settlement Prediction Market] Hyperliquid announced that Outcome Markets (HIP-4) has officially launched on the mainnet, currently as an initial version with limited functionality. Outcome Markets is a fully collateralized contract that settles within a fixed range, suitable for scenarios such as prediction markets and range options. It does not involve leverage or liquidation mechanisms, with the primary goal in the first phase being to validate technical implementation. The first market to go live is a daily binary Outcome contract, which will settle at 06:00 (UTC) each day based on the BTC mark price on Hyperliquid. The official statement noted that additional features and market types will be introduced in phases, and community feedback is welcomed.
