Hyperliquid has enabled permissionless deployment of HIP-4 outcome markets on mainnet, letting outside builders create prediction markets without requiring validators to approve each listing. Deployers must still use market templates approved by Hyperliquid validators and meet the protocol’s staking requirements.
The change expands HIP-4 beyond its earlier validator-controlled model, where validators determined which outcome markets could be deployed. Hyperliquid first introduced outcome markets on mainnet in May before testing permissionless deployment and moving the feature to mainnet on August 29.
Deployers Must Meet 500,000 HYPE Staking Requirement
Permissionless HIP-4 deployers must meet a 500,000 HYPE staking requirement, with the stake subject to a six-month lock. Validators can slash part or all of the stake if markets are poorly defined, settled incorrectly or remain incorrectly unsettled for more than one week. Hyperliquid said:
“Permissionless deployments are especially important for the growth of outcome markets.”
Builders define and settle individual markets according to the criteria in their selected templates. The mainnet rollout starts with conservative limits. Each deployer can maintain up to 100 concurrent outcomes and create as many as 500 new outcomes per day, with Hyperliquid planning to raise those limits after the system stabilizes.
Validators Still Approve Market Templates
Permissionless deployment does not mean builders can create any type of prediction market. Validators continue to approve standardized templates, while deployers can launch individual markets that fit within those structures without seeking a separate validator vote.
At launch, approved templates are focused mainly on financial outcomes, including asset-price movements and policy-rate decisions. Sports-market templates used during earlier HIP-4 testing are not currently included in the mainnet permissionless template set.
Outcome and Skew Begin Deploying Markets
Outcome and Skew are among the first builders using the new system. Available markets include questions tied to Bitcoin, HYPE, stock indexes, commodities and Federal Reserve decisions, while Skew has introduced shorter-term Bitcoin price markets.
The upgrade shifts responsibility for creating individual markets toward third-party deployers while validators retain approval authority over the available templates. Further expansion will depend on additional templates receiving validator approval and the protocol increasing its initial deployment limits.
