HIP-4 upgrade allows external operators to launch markets on testnet ahead of mainnet rollout
Hyperliquid announced plans on July 19 to roll out HIP-4, an upgrade enabling external operators to launch prediction markets on its blockchain platform. Each deployer must stake 500,000 HYPE tokens, worth approximately $31.7 million at Monday’s token price, to participate.
The mechanism grants operators control over which questions they list and how markets settle, while Hyperliquid validators retain authority over broader rules, standardized templates, and penalties for unclear or improperly resolved markets. Contracts are fully collateralized and settle at 0 or 1 depending on event occurrence, with no leverage allowed, limiting maximum loss to the amount paid for a position.
Deployers receive initial capacity for 100 outcomes, represented by up to 200 tradable outcome tokens. Settled contracts free up capacity for future markets. Hyperliquid plans to add an auction mechanism for operators seeking larger allocations. The required HYPE stake remains locked for six months. Deployers must settle all outstanding markets before withdrawing their stake.
Validators can seize part or all of a deployer’s stake if the operator records an incorrect result, fails to resolve within one week, or launches a market with unclear settlement terms. Validators would approve standardized templates governing specific market types, with requirements stored and enforced on-chain.
Builder momentum in derivatives
HIP-4 extends Hyperliquid’s existing permissionless framework for market creation. The platform’s HIP-3 perpetual futures framework already permits independent developers to list customized derivative contracts. Builder-deployed contracts grew from 2% of volume at the beginning of 2026 to approximately 50% of daily trading volume.
TradeXYZ leads this expansion with perpetual contracts linked to the Nasdaq-100 and companies including Nvidia and Tesla. These contracts remain tradable at night and on weekends, unlike US-listed stocks.
Prediction-market landscape
Polymarket has built a wide catalog spanning politics, sports, digital assets, and cultural events with an interface designed around discovering and comparing questions. Kalshi uses its regulated US position to expand sports trading and deepen relationships with financial institutions.
Decentralized prediction venues processed over $311 billion in cumulative volume as of July 2026, across 1.65 billion transactions. The venues have drawn 4 million users. Prediction-market trading during the World Cup was equivalent to about 27% of legal US sports-betting volume, up from roughly 9% at the beginning of the year.
Bernstein forecasts annual prediction-market volume could reach $1 trillion by 2030, compared with $51 billion in 2025.
Operator economics
Operators can receive up to 50% of the fee share from markets they operate. The upgrade is slated to launch on testnet before mainnet deployment. Hyperliquid approaches prediction markets through its existing derivatives trader base, providing execution infrastructure while outside operators develop contracts and interfaces.
