Hyperliquid’s HIP-4 (Hyperliquid Improvement Proposal 4) is making waves as the biggest challenge Polymarket has seen so far. This upgrade, now in public testnet, adds native outcome trading—prediction-style contracts—to Hyperliquid’s fast L1.
What HIP-4 Delivers
- HIP-4 introduces binary and fixed-range contracts that settle at 0 or 1, depending on real-world events like elections, BTC price targets, sports, or macro news.
- All positions are fully collateralized with no leverage and no risk of liquidation. The most you can lose is your initial stake.
- Prediction contracts work smoothly with perpetuals and spot markets, all in a single margin account. This setup allows for better hedging and more efficient use of capital.
- You may pay no fees to open positions, with fees charged only when you win or exit.
Hyperliquid, a leading decentralized exchange, is testing a new system upgrade called HIP-4, allowing traders to bet on real-world outcomes, marking its entry into prediction markets and potentially challenging incumbents like Polymarket and Kalshi.

Why Analysts Call It a Game-Changer
- Traders can hold prediction contracts and high-leverage perpetuals together, without needing to move funds between different platforms.
- This approach removes the problem of ‘dead capital’ that often happens on standalone apps like Polymarket.
- User Base Overlap: 14% of top Polymarket tradersAbout 14% of top Polymarket traders are already using Hyperliquid, with around $1.43 billion in trading volume. This overlap makes it very easy for users to switch.en via buybacks and staking.
Arthur Hayes and others have called HIP-4 a possible ‘weapon’ for prediction market dominance because it offers deeper liquidity, faster execution, and built-in DeFi integration.
Current Status
The testnet is live with outcome tokens. The mainnet launch is expected soon, and Polymarket users are already betting on when it will happen. The HYPE token has responded well to the news.
2026 Outlook
HIP-4 changes prediction markets from separate apps into a fully integrated DeFi building block. If it draws in more retail users beyond the current power users, it could quickly take volume from Polymarket and Kalshi. Governance, oracle reliability, and regulatory issues—especially for U.S. users—are still important to watch.
This upgrade puts Hyperliquid in a strong position to gain more of the fast-growing prediction market sector, where monthly volumes are already in the tens of billions. Competition for on-chain event trading is getting intense.
