Overview
- Hyperliquid published an official fee schedule for its event‑betting outcome tokens, signaling progress toward the HIP‑4 rollout.
- Under the plan, opening a position is free and fees apply only when traders close or settle a contract.
- Outcome contracts are live on testnet and the company has not announced a mainnet date.
- HIP‑4 would let traders hold event bets and perpetual futures in one account on Hyperliquid’s L1, using the same collateral for cross‑margining.
- Competitors are converging on similar features, with Kalshi preparing a perpetuals product and Polymarket adding 10x leverage, in a market that saw $63.5 billion in 2025, while observers warn that oracle reliability, resolution disputes and a trader‑centric interface could limit retail uptake.
