Hyperliquid's HIP-4 Goes Permissionless on Testnet — Can it Capture Midterm Volume for HYPE?

Executive summary

Hyperliquid's HIP-4, which enables outcome markets for binary events, has moved to permissionless deployments on testnet as of July 31st, according to Bankless. This upgrade aims to transition from a validator-controlled system, where validators deploy every market, to one where external deployers can create and operate their own outcome markets. The previous iteration of HIP-4 experienced its most significant success with World Cup-related markets, which accounted for approximately 48% of its trading volume to date. However, following the conclusion of the tournament, open interest has declined by over 90%, with current volume described as trivial compared to the activity spurred by sports events.

The preliminary mainnet design for permissionless HIP-4 involves validators approving market templates, which deployers then use to launch specific markets by providing details such as the question, outcomes, and resolution criteria. Deployers will be responsible for market settlement and are required to stake 500,000 HYPE tokens, locked for six months, with potential slashing for incorrect settlements. They will also be eligible to receive up to 50% of the trading fees from their markets. The primary near-term target for these new markets is the U.S. midterm elections, an event historically known to generate substantial interest in prediction markets on platforms like Kalshi and Polymarket.

Why it matters

The transition to permissionless deployments for HIP-4 represents a critical structural change for Hyperliquid, aiming to diversify its market offerings and reduce reliance on a centralized validator team for market creation. If successfully implemented on mainnet before the U.S. midterms, this could significantly impact capital flows and liquidity within the Hyperliquid ecosystem. The requirement for deployers to stake 500,000 HYPE tokens, valued at approximately $27.3 million at the current HYPE price of $54.67, could create substantial buy pressure and reduce the circulating supply of HYPE. This mechanism is designed to incentivize responsible market creation and settlement while also acting as a demand driver for the token.

From a liquidity perspective, opening up market creation to external deployers has the potential to dramatically increase the breadth and depth of outcome markets on Hyperliquid. The current low open interest post-World Cup suggests a supply-side constraint, which permissionless deployments could alleviate. Attracting institutional-grade market makers or specialized prediction market teams as deployers would enhance market efficiency and liquidity. The ability for deployers to earn up to 50% of trading fees provides a strong economic incentive, potentially attracting professional entities. However, the exact timeline for mainnet deployment remains uncertain; HIP-3, a prior upgrade, took 164 days from testnet MVP to mainnet, and HIP-4 currently lacks mainnet-level bug bounties, suggesting a potentially lengthy development period. Missing the midterm window would mean Hyperliquid loses a prime opportunity to demonstrate the viability of its permissionless model and attract initial deployer capital, potentially delaying sustained trading volume growth for the HIP-4 segment.
