ArbMonster — prediction market & sportsbook arbitrage scanner

ArbMonster is a market-data analytics service. It displays observed pricing across public venues and does not place trades, hold funds, or provide betting, investment, or wagering advice.

Cross-venue market pairings labeled “AI-matched” are assessed automatically and shown with a confidence score. Markets on different venues can resolve differently in edge cases. It is your responsibility to verify both markets' resolution criteria before acting; ArbMonster accepts no responsibility or liability for resolution differences between venues or for decisions made using this data.

ArbMonster is a research and educational data tool. Venue availability varies by state; verify what is available where you live. You must be of legal age in your jurisdiction (21+ in most US states) to trade on the venues shown.
