# Prediction Market Arbitrage: 12 Live Opportunities Surfaced by StartupHub.ai Engine _StartupHub.ai's cross-venue engine has identified 12 live prediction market arbitrage opportunities as of August 2, 2026, allowing users to lock in guaranteed payouts._ **Published:** 2026-08-02 **Source:** https://www.startuphub.ai/ai-news/prediction-markets/2026/prediction-market-arbitrage-12-live-opportunities-surfaced-by-startuphub-ai-engine --- Today, August 2, 2026, StartupHub.ai's proprietary cross-venue engine has surfaced 12 live prediction market arbitrage opportunities. These opportunities arise when the same real-world event is priced differently across two or more prediction market venues, such as Polymarket, Kalshi/Robinhood, and PredictIt. An arbitrage lock occurs when buying a 'YES' contract on one venue and a 'NO' contract on another for the same event costs less than $1 combined, guaranteeing a profit regardless of the outcome. While our engine continuously monitors for these spreads, they can close rapidly as market participants capitalize on the mispricing. The opportunities detailed below are live as of this writing; any others that opened in the last few hours may have already closed. It is crucial to remember that this information is not financial advice, and factors like fees, KYC requirements, and withdrawal limits can impact actual returns. Arbitrage ROI by event.
