In a significant development, Hyperliquid has unveiled its fee structure for outcome tokens, paving the way for a potential mainnet launch. This move is particularly noteworthy given the explosive growth of the prediction market sector, which has seen trading volumes skyrocket by over 300% in 2025 to $63.5 billion. Hyperliquid is strategically positioning itself to compete with established players like Kalshi and Polymarket by building a robust infrastructure.
A key feature of its fee structure is that opening a position is free, with fees only applicable when closing or settling a trade. The company has outlined six scenarios covering minting, trading, burning, and settlement, with traders using aligned quote tokens benefiting from better rates, including 20% lower taker fees and 50% higher maker rebates. The introduction of outcome tokens, as part of the HIP-4 upgrade, will enable users to trade binary contracts on real-world events, alongside perpetuals and spot positions, all within a single account, thereby enhancing its competitiveness against platforms like Polymarket.
Following the success of its previous upgrade, HIP-3, which has accounted for over 35% of the platform's trading volume since its introduction in October 2025, Hyperliquid is now gearing up for the next phase of its growth.
