Hyperliquid is accelerating its entry into the prediction market arena, planning to compete with platforms like Polymarket and Kalshi through its newly launched "outcome tokens" mechanism. According to its latest fee structure, Hyperliquid adopts a "zero-fee opening, fee-based closing or settlement" model for event trading, covering various scenarios including minting, trading, burning, and settlement. The platform also offers lower trading costs for "aligned quote tokens," including increased market-making rebates and fee discounts. This feature will be introduced through the HIP-4 upgrade, allowing users to trade binary contracts based on real-world events within the same account and integrating with the existing spot and perpetual contract system to form a unified trading environment. The prediction market has grown rapidly in recent years, with a total trading volume exceeding $63.5 billion by 2025. Hyperliquid's previously launched HIP-3 has already driven its permissionless perpetual contract market to account for over 35% of the platform's trading volume. The event token is currently in the testnet phase, and the mainnet launch date has not yet been announced. However, it is widely believed in the industry that it will become a crucial infrastructure for Hyperliquid to challenge the existing prediction market landscape. (CoinDesk)
