Hyperliquid Unveils Prediction-Market Fee Structure to Challenge Polymarket’s Lead

Hyperliquid, a decentralized trading platform best known for onchain perpetual futures, is seeking to expand into prediction markets through its HIP-4 upgrade. The permissionless model would allow third-party deployers to create markets tied to future events, potentially broadening the platform’s product mix and trading activity while using economic incentives to support liquidity, reliable pricing and market quality.

Hyperliquid said HIP-4 prediction markets will launch on testnet before a planned mainnet rollout, though it has not disclosed firm deployment dates. Each permissionless market deployer will be required to stake 500,000 HYPE tokens, creating a substantial financial threshold intended to discourage low-quality markets. In return, deployers may receive as much as 50% of the trading fees generated by their markets.

Hyperliquid began as an onchain venue for crypto perpetual futures. Through HIP-3, it now allows builders to launch round-the-clock markets for equities, commodities, foreign exchange and Pre-IPO assets, while HIP-4 marks its entry into event prediction. The strategy brings crypto assets, RWAs and outcome contracts under a single account, expanding its competitive field from CME Group to Kalshi and Polymarket.

HIP-4 went live on May 2, 2026, followed on May 25 by offchain event markets settled by validators. The first markets covered May's year-on-year CPI rate and the Federal Reserve's June interest-rate decision. FalconX said the 21Shares and Bitwise HYPE spot ETFs recorded combined net inflows of $53 million over several days. Hyperliquid's USDC partnership with Coinbase and Circle is estimated to generate $160 million in annual revenue.

On March 16, 2026, the U.S. Commodity Futures Trading Commission issued an advance notice of proposed rulemaking on prediction markets, RIN 3038-AF65, seeking input on market oversight and the public-interest boundaries governing event contracts. The Hyperliquid Policy Center was concerned that rules based on assumptions about centralized exchanges could leave non-custodial onchain markets without a lawful path to operate.

On April 30, 2026, the consultation deadline, HPC submitted a 15-page comment letter, CFTC No. 115408. It called for flexible, function-based rules, a clear legal pathway for U.S. users to participate in decentralized prediction markets and support for U.S. onchain financial innovation. The letter did not discuss any investment amount; its policy objective was to provide regulatory certainty for Hyperliquid and HIP-4 outcome markets.
