Get prediction-market arbitrage
get_arbitrageRead-only
Live cross-venue prediction-market arbitrage board. Returns the same real-world events priced on Polymarket, Kalshi/Robinhood, and PredictIt side by side, with a real arbitrage flagged whenever the combined cost of locking a $1 payout drops under $1 (is_arbitrage=true, with roi_pct + profit_per_dollar). Each opportunity carries both legs (venue, price, direct trade URL), the combined cost, and when the arb last opened. Refreshed every 30 minutes. Free tool, no API key. Pass arbs_only=true to return only the live arbitrages. Built for trading agents that poll for tradeable spreads: informational only, verify each market's exact resolution rules, fees, and withdrawal terms before trading.
