According to Techub News, Hyperliquid will introduce Portfolio Margin in its upcoming network upgrade, a feature already launched in pre-alpha mode on the testnet. Under Portfolio Margin, margin for spot and perpetual contract trading will be completely unified, significantly improving capital utilization efficiency. Furthermore, the Portfolio Margin account will automatically generate returns on all lendable assets not actively used for trading. All HIP-3 DEXs are included in the Portfolio Margin calculation, but not all HIP-3 DEX collateral assets are lendable. Future HyperCore asset classes and derivatives primitives will also support Portfolio Margin. Users can provide liquidity to eligible quoted assets to earn returns.
