Thales' main breakthrough is the ability to offer Parimutuel Markets on Optimism, Polygon and Arbitrum networks. In Parimutuel Markets, collateral is placed in a single shared pool, and that pool is awarded to winning participants after a market-settling event has occurred. Market-settling event can be one of the two mutually exclusive outcomes (e.g. Thales Positional Markets), or it can be one of many mutually exclusive outcomes (e.g. Thales Exotic Market with multiple options). The payoff for these types of markets can be easily understood as the total pool (minus the house fee) shared across all winning positions.
