Hyperliquid expands capabilities with HIP-4 outcome markets

Hyperliquid just added prediction markets to its playbook. The Layer-1 blockchain launched HIP-4 on May 2, 2026, introducing native outcome markets where contracts settle based on real-world events, essentially binary bets that resolve to either 0 or 1.

The first day wasn’t quiet. Over 6.05 million contracts changed hands on launch day.

How HIP-4 actually works

Each contract trades as a probability, priced somewhere between 0.001 and 0.999. If the outcome you bet on happens, your contract settles at 1. If it doesn’t, it settles at 0.

The first market deployed was a daily binary outcome based on Bitcoin’s mark price, managed by builders like Outcomexyz/Outcome.

Unlike traditional perpetual futures or leveraged positions, these outcome markets are fully collateralized. That means no funding rates and no liquidation risk.

Hyperliquid also built these markets with merged order books, meaning the Yes and No tokens share liquidity rather than fragmenting it across separate pools.

Initial trading fees are set to zero for the testing phase, though builder fees still apply to sell orders.

The rollout plan and competitive context

HIP-4 is deploying in two phases. The current phase features curated canonical markets. Phase two will open the gates to permissionless deployment, letting any builder create new markets and making them accessible through any wallet interface.

Future plans also include multi-outcome markets, which would expand beyond simple yes/no binaries into scenarios with three or more possible results.

The announcement of HIP-4 on February 2, 2026, preceded the actual launch by several months. During that announcement window, Hyperliquid’s native token HYPE jumped approximately 10% within 24 hours.

A testnet deployment ran earlier in 2026 before the mainnet launch.

What this means for investors

The merged order book design means Yes and No tokens share liquidity rather than splitting it across separate pools, giving Hyperliquid a structural advantage over standalone prediction platforms that need to bootstrap liquidity from scratch.

The zero-liquidation-risk design opens the door to a different type of trader. Perpetual futures attract leverage-hungry participants. Outcome markets, by contrast, could pull in users who want exposure to event-based risk without the complexity of managing margin positions.

Risks are worth noting. Outcome markets require reliable settlement mechanisms, and the transition to permissionless deployment introduces questions about market quality and potential manipulation in thinly traded contracts. Builder curation in phase one mitigates this, but phase two will test the protocol’s governance and oracle infrastructure.
