Important distinction
Prediction-market availability and legality are jurisdiction-specific. Do not use VPNs or other workarounds to bypass restrictions.Direct answer
A prediction market is a venue or app where users trade event outcomes. An outcome market is the contract format underneath one of those trades. Hyperliquid HIP-4 is best understood as infrastructure for outcome contracts, not as a complete substitute for every prediction-market platform.
