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.
