Totalis is a platform that allows users to combine multiple prediction markets into a single parlay trade. Unlike traditional sports betting parlays, Totalis enables cross category combinations across crypto prices, politics, economic indicators (e.g., Fed rate cuts), weather, and other event types. Users select outcomes from different markets, combine them into one position, and receive a custom payout multiplier based on the combined probability. The platform provides a custom pricing engine that gives instant quotes from market makers rather than using a rigid order book.
