Overview
Predly uses AI models to independently calculate outcome probabilities for prediction markets on Polymarket and Kalshi, then compares its estimates to actual market prices. When a significant discrepancy is detected — when the market price diverges from what the model believes is the true probability — Predly generates an alert with the market, the mispricing direction, and the estimated edge.
