Cross-venue prediction-market arbitrage board

The same real-world events priced on Polymarket, Kalshi/Robinhood, and PredictIt side by side, with a live arbitrage flagged whenever the combined cost of locking a $1 payout drops under $1. Refreshed every 30 minutes. Free, no API key; a paid Bearer key unlocks each leg's direct trade URL. Informational only: verify each market's resolution rules, fees, and withdrawal terms before trading.
