Hyperliquid said its HIP-4 upgrade will support permissionless deployment of prediction markets in a future enhancement, allowing anyone to list event contracts on the decentralized exchange, according to a statement the team posted on Telegram on Sunday.
To deploy, builders will be required to stake 500,000 HYPE — about $30 million at the token's current price near $60, per CoinGecko — which validators can slash through a vote if they determine a market was poorly defined or settled incorrectly. Deployers will earn up to 50% of the revenue from trading fees on their markets.
HIP-4 introduced "outcome trading" to Hyperliquid and went live on mainnet in May. Prediction markets currently remain under the authority of validators, who approve each listing.
Under the planned change, validators will instead vote on standardized outcome templates that define how markets are structured and enforced on-chain, letting deployers launch new markets using approved formats without per-listing approval. Permissionless markets will roll out first on testnet and later on mainnet.
Validator-controlled markets will continue to exist but are expected to be rare — "ideally" fewer than 10 per year, Hyperliquid said.
