Why It Matters

Supporting multiple prediction market venues typically requires separate APIs, unique market models, different authentication methods, and custom trading logic for each platform. OpenMarkets removes this complexity by normalizing market data, pricing, and execution into a single developer interface. Teams can build once against a unified API while accessing multiple venues for market discovery, account connectivity, pricing, and trade execution, significantly reducing engineering effort as new venues are added.
