Woofun AI reports that Melee, a prediction market protocol within the Solana ecosystem, has published a litepaper detailing its Parimutuel Market Maker (PMM) mechanism. This trading model is engineered specifically for permissionless prediction markets, aiming to resolve the dilution of early participant returns inherent in traditional parimutuel systems. The PMM framework integrates dynamic pricing curves and establishes a minimum-return floor, enabling market launches immediately upon initial funding without reliance on professional market makers. Settlements occur peer-to-peer among participants, while early investors and presale contributors receive liquidity rewards from counterparties.

Additionally, non-directional capital can be withdrawn via the cashout LP vault to generate returns. Melee previously secured $3.5 million in Pre-Seed funding in September 2025, with backing from DBA, Variant, and angel investors, followed by the launch of its Alpha version in October 2025.
