Hyperliquid is moving to open up its HIP-4 prediction markets with a permissionless deployment model, starting on testnet and headed to mainnet after community feedback and testing. The key change: validators will no longer need to approve each new market. Instead, they will vote on standardized outcome templates that define how markets must be structured. Those templates will be stored and enforced on-chain, letting anyone launch markets that conform to approved formats rather than requiring individual validator sign-off for every listing. Market deployers will build and settle individual markets according to an approved template. Validator-run “canonical markets” will still exist but are expected to be rare — Hyperliquid anticipates fewer than 10 such outcomes per year created via validator votes. To deter low-quality or malicious listings, deployers must stake 500,000 HYPE. Validators may partially or fully slash that stake if markets are poorly specified, settled incorrectly, or left unresolved for more than a week. The stake will be locked for six months (consistent with HIP-3), and deployers must settle all outstanding markets before withdrawing their locked HYPE. Each deployer initially gets capacity for 100 outcomes (equivalent to 200 outcome tokens); multi-outcome markets consume more capacity, while settled markets free up capacity for new deployments. Hyperliquid also plans an auction mechanism that will let deployers increase their allocation. Market creators will be able to charge fees of up to 50% on their markets. The team emphasizes the proposal is preliminary and may be adjusted after community input. This permissionless push builds on Hyperliquid’s May rollout of HIP-4, which brought prediction markets to the network and recorded roughly $100 million in trading volume in its first month. The update arrives as Hyperliquid’s profile grows in both DeFi and traditional finance: Bitwise recently added HYPE to its Bitwise 10 Crypto Index ETF (BITW) with about a 0.95% allocation. Bitwise’s inclusion followed Hyperliquid’s reported $1.34 trillion in trading volume and $320 million in revenue during the first half of 2026, per Bitwise’s index update and prior reporting. Next steps: the permissionless deployment will appear on testnet first so the community can vet the mechanics and parameters before a mainnet rollout. Hyperliquid is soliciting feedback and may refine the proposal based on community response.

Summary
Hyperliquid has launched permissionless prediction markets on testnet, using on-chain data to enable market deployers to launch via on-chain templates. A 500,000 HYPE stake is required, with slashing for poor execution. The update follows the May HIP-4 rollout, which saw $100 million in first-month volume. Bitwise added HYPE to its BITW ETF with a 0.95% allocation. The model will be tested before mainnet deployment.
