What Is HIP-4?
HIP-4 is the fourth Hyperliquid Improvement Proposal — the upgrade that adds native prediction market primitives to Hyperliquid's Layer-1 blockchain. It extends Hyperliquid's
existing on-chain order-book infrastructure (originally built for perpetual futures) to support event contracts whose payoff depends on real-world outcomes.
HIP-4 turns Hyperliquid into a venue where users can trade both perpetuals and prediction markets from the same self-custody wallet, on the same on-chain order book, with the same matching engine and the same fast block times.
How Does HIP-4 Work?
A market is created on Hyperliquid for a defined future event with a resolution date.
The HIP-4 contract issues "Yes" / "No" outcome tokens that together always pay $1 in USDC collateral.
Users place orders directly on Hyperliquid's on-chain order book.
Matching, position tracking, and settlement happen on Hyperliquid's L1.
At resolution, an oracle posts the outcome on-chain and winning tokens redeem 1:1.
Users can withdraw collateral back to their self-custody wallet at any time.
Key Features of HIP-4
Native L1 Integration
Prediction markets settle on the same Hyperliquid L1 as Hyperliquid's perpetuals — no bridging.
On-Chain Order Book
HIP-4 markets use Hyperliquid's CLOB, preserving price-time priority and giving traders tight spreads.
USDC-Settled
Collateral, trading, and payouts use USDC, matching the rest of the Hyperliquid platform.
Same Wallet, Multiple Asset Types
Users trade perpetuals and prediction markets from a single self-custody wallet without switching venues.
High Throughput
Hyperliquid's L1 is designed to process tens of thousands of orders per second, making HIP-4 markets responsive even under load.
