According to BlockBeats, on July 20, Hyperliquid announced plans to introduce a permissionless prediction market deployment mechanism through HIP-4, requiring developers to stake 500,000 HYPE tokens (approximately $30.4 million) to create a prediction market.

The mechanism aims to reduce the risks of low-quality markets, erroneous settlements, or malicious market creation through capital thresholds and penalties.

According to Hyperliquid's announcement, the permissionless deployment feature will first be available on the testnet and will be deployed to the mainnet via network upgrades in the future. Validators will vote to determine standardized result templates, and developers can create marketplaces based on these templates, with each deployer initially creating a maximum of 100 result options.

Deployers are responsible for defining market rules and completing settlements according to the template requirements. Staking HYPE will be locked for 6 months. If the market definition is unclear, the settlement is incorrect, or the correct settlement is not completed within one week, validators can reduce their staked assets through voting.

Hyperliquid stated that compared to spot and perpetual contract markets, the range of predictable events is broader, making permissionless prediction market deployments crucial for expanding on-chain application scenarios. The relevant rules may be further adjusted before the testnet launch.
