Hyperliquid's (HIP-4) is cool: If Outcomes compose with perps, you can long ETH + buy an 'ETH below $2k' outcome as a hedge, and your margin drops because the positions offset each other. Polymarket or Kalshi can't do this. Another innovation is permissionless deployment. Polymarket curates its markets but if Hyperliquid lets anyone create markets, the long tail of degen markets opens up. I'd like governance vote events or maybe degen memecoin events? Probably will require some HYPE staking like HIP3? Otherwise 'murder events' pose risk for HL. Another one is settlement. Polymarket suffers from oracle quality. What is their "Objective settlement sources"? That could be real innovation that Poly/kalshi suffer from. Plus, HL is much faster than Polymarket's Polygon.(Ignas | DeFi)
