Prediction Market Arb Scanner — Polymarket + Kalshi + PredictIt

FinancePolymarketKalshiPredictIt

Scans Polymarket, Kalshi, and PredictIt for matching binary prediction markets and surfaces every cross-platform pair where buying YES on one and NO on the other locks in a risk-free profit. Wider net than a single pair — three platforms means three pairwise comparisons per scan.
