[Hyperliquid Plans to Explore Zero Opening Fee Prediction Market to Challenge Polymarket] Odaily Planet Daily News: Hyperliquid is accelerating its entry into the prediction market sector, aiming to compete with platforms like Polymarket and Kalshi through a newly introduced 'outcome tokens' mechanism. According to the latest disclosed fee structure, Hyperliquid adopts a 'zero opening fee, closing or settlement fee' model for event trading, covering multiple scenarios such as minting, trading, burning, and settlement. The platform also offers lower transaction costs for 'aligned quote tokens,' including enhanced market-making rebates and fee discount mechanisms. This feature will be introduced through the HIP-4 upgrade, enabling users to trade binary contracts based on real-world events within the same account and integrate them with the existing spot and perpetual contract systems, creating a unified trading environment. The prediction market has seen rapid growth in recent years, with overall trading volume exceeding $63.5 billion by 2025. Hyperliquid's previously launched HIP-3 has driven its permissionless perpetual contract market to account for over 35% of the platform's trading volume. Currently, outcome tokens are still in the testnet phase, and the mainnet launch date has not yet been announced. However, the industry widely believes this will become a critical infrastructure for Hyperliquid to challenge the existing prediction market landscape. (CoinDesk)
