The Infrastructure Behind Prediction Markets
Platforms like Kalshi, Polymarket, and Metaculus built their own prediction market engines from scratch — spending millions and years of development. PredictAPI gives you that same technology as a ready-to-integrate API.
Like Kalshi — For Your Brand
Kalshi built a CFTC-regulated exchange from scratch. You don't need to. PredictAPI gives you the same order-book matching, binary event contracts, and settlement engine — white-labeled under your brand.
Like Polymarket — Without the Crypto Complexity
Polymarket pioneered on-chain prediction markets. PredictAPI brings the same UX and market mechanics, but without requiring blockchain integration. Support any currency, any payment method.
Like Metaculus — With Monetization Built In
Metaculus excels at forecasting questions. PredictAPI turns forecasts into tradeable markets where your users put real money behind their predictions, creating deeper engagement and revenue.
