Hyperliquid HIP-4 Trails Prediction Market Rivals

Hyperliquid HIP-4 combines event contracts and perpetual trading in one account with shared margin, giving traders a way to hedge without leaving the platform. Markets can be launched by staking 500,000 HYPE, with settlement rules set before trading begins. Entry is free, while protocol fees are generally charged on exit. Adoption remains modest. From its launch on 2 May to 5 October 2026, HIP-4 recorded about $317 million in cumulative volume. September volume was around $51 million, compared with $59.3 billion on Kalshi and $13 billion on Polymarket and its US business combined. HIP-4’s volume was about 1,400 times smaller than Kalshi’s. Activity is concentrated in sports, which account for about two-thirds of open risk; crypto-price contracts make up 17%. Daily Bitcoin markets have also weakened. Three external venues have launched, but Outcome accounts for about 92% of their volume. Its $1 million incentive programme had paid out roughly $273,000 to 2,487 wallets by 5 October. The rewards may be propping up activity: Outcome is reportedly spending about $2.7 million a year on incentives, while HIP-4’s current fee level implies around $480,000 in annual trader payments. Liquidity is thin, and large orders can move prices by 2% to 3%, limiting the platform’s appeal for institutional-sized trades. HIP-4’s shared margin and hedging features make it a useful addition for Hyperliquid traders, but narrow market coverage, limited liquidity and reliance on incentives leave it far behind established prediction-market rivals. For now, HIP-4 appears more likely to remain a platform feature than to become a leading prediction-market business.
