In a significant development, Hyperliquid has unveiled its fee structure for outcome tokens, paving the way for a mainnet launch and marking a crucial step towards competing with established players like Kalshi and Polymarket in the burgeoning prediction market space. With a staggering 300% surge in trading volume in 2025, reaching $63.5 billion, Hyperliquid is strategically building its infrastructure to capitalize on this trend.
A key feature of the platform is the absence of fees for opening positions, with charges only applying when trades are closed or settled. The fee structure encompasses six distinct scenarios, including minting, trading, burning, and settlement, with traders utilizing Hyperliquid's aligned quote tokens eligible for preferential rates, including 20% lower taker fees and 50% higher maker rebates.
The introduction of outcome tokens, as outlined in the HIP-4 upgrade, will enable users to trade binary contracts on real-world events alongside perpetuals and spot positions from a single account, positioning Hyperliquid to rival platforms like Polymarket. Following the successful introduction of permissionless perpetuals for developers via the HIP-3 upgrade, which now accounts for over 35% of the platform's trading volume since its launch in October 2025, Hyperliquid is cementing its presence in the market. Currently, outcome tokens are available on testnet, with a mainnet launch date yet to be confirmed.
