OpenMarkets

OpenMarkets is the infrastructure layer for cross-market trading. Prediction markets and sports trading venues each quote their own prices for the same event. OpenMarkets connects those venues into one network, normalizes their data in real time, and surfaces the best available line across every market.

For traders, that means one place to compare prices instead of a browser full of venue tabs. For operators and developers, it means a single platform and API instead of a venue-by-venue integration effort. The platform covers cross-venue price data, order-book depth, liquidity metrics, and execution routing. Venues like Kalshi and Polymarket are already integrated, and the data model stays consistent as more venues join the network, so you integrate once and every new venue arrives for free.

The design is asset-light and global. Trading, liquidity, KYC, and wallets stay with the venues themselves, while OpenMarkets provides the connectivity and intelligence layer on top. The platform does not hold customer funds and does not run its own order books. That keeps it focused on what it does best: normalized real-time prices, depth and liquidity analytics, and routing to the best available line across every connected market.

OpenMarkets is built operator-first and agent-native. The same API that powers the platform is open to developers, so an app, a trading desk, or an AI agent can read prices, compare markets, and route orders through one integration instead of many. Developers can start today at app.openmarkets.ai.

If you trade across prediction markets, or you are building a product that needs clean cross-venue market data, OpenMarkets gives you the best lines and odds across all markets from a single point of access.
