Frequently Asked Questions

What does a sports arbitrage scanner do?

It continuously compares odds across multiple sportsbooks and prediction markets, finds events where the combined implied probability of opposing bets is less than 100%, and surfaces the resulting risk-free profit opportunity.

How often do sports arbitrage opportunities appear?

On a busy NFL or NBA day, expect 20-50 windows per hour at 0.5-2% edge. Smaller leagues (MLS, college basketball) often produce larger edges (3-5%) due to thinner market efficiency.

Will sportsbooks ban me for arbitraging?

Aggressive arbing can trigger account limits at retail sportsbooks. PredictEngine's smart sizing keeps individual sportsbook activity within normal bettor patterns to minimize this risk.

Can I run a sports arbitrage scanner for free?

PredictEngine offers a free tier with scanner access. Auto-execution and higher-frequency scanning unlock with paid plans starting under $30/month.
