Prediction Market Arbitrage
Calculate cross-venue arbitrage: gross spread, fee-adjusted net edge, capital required, and the minimum spread needed to survive fees. A 5% gross spread on Polymarket/Kalshi yields roughly 3% net after Kalshi's parabolic taker fee.
Not financial advice. Arbitrage opportunities are transient and may disappear before execution. Verify current prices and fees with each venue. This tool does not access live prices or execute orders.
