What is arbitrage betting?
Arbitrage betting ("arbing") means backing both sides of the same market at two different sportsbooks whose odds disagree enough that you lock in a profit no matter the outcome. If one book has the Over at +105 and another has the Under at +102, the right stakes on each side guarantee a return. The opportunities are real — books move lines at different speeds and disagree constantly — but they vanish fast, which is why finding them by hand doesn't work.
This arbitrage finder scans 40+ sportsbooks and betting exchanges around the clock — moneylines, spreads, totals, alternate lines and player props across the NFL, NBA, MLB, NHL, college sports, soccer, tennis, golf, UFC and esports. Every arb shows both legs, the guaranteed profit percentage, and a built-in stake calculator that sizes each bet from your total stake. You can restrict results to specific book pairs, filter by league, market, odds range and time to start, and push notifications to your phone or browser the second a new arb clears your thresholds.
A free account includes a live preview of arbs up to 0.5% profit; paid plans unlock every arb, live in-game markets and real-time alerts.
