The #1 Arbitrage Betting Tool

Arbitrage betting (also called surebetting or arbing) is when you place bets on all possible outcomes of an event across different sportsbooks, locking in a guaranteed profit regardless of the result. It works because sportsbooks set odds independently, and price differences between them create opportunities where the combined implied probability is less than 100%.

Individual surebets typically yield 1-5% profit per bet. While each arb is small, there is zero risk involved. With sufficient capital spread across multiple sportsbooks and consistent daily volume, monthly returns compound quickly. Many arbers treat this as steady income rather than gambling.

Yes, arbitrage betting is completely legal everywhere. You are simply placing bets at different sportsbooks using publicly available odds. No laws prohibit this. However, sportsbooks can limit or close accounts that they identify as arbing. Using multiple books and varying your bet sizes helps extend account longevity.

The calculator tells you exactly how much to place on each side to guarantee equal profit regardless of the outcome. Bet Hero also shows calculated stakes directly on every surebet alert.

Surebets (arbitrage) guarantee profit on every single bet by covering all outcomes across different sportsbooks. There is zero risk. Value bets identify wagers where the odds exceed the true probability, giving you a mathematical edge, but individual bets can still lose. Value betting has higher long-term ROI but comes with short-term variance. Many bettors do both.

Eventually, some will. Sportsbooks track betting patterns and may limit accounts that consistently exploit price differences. This is normal and expected in arbitrage betting. The strategy is to maintain accounts at as many books as possible, vary your bet sizes, and avoid arbing only the most obvious opportunities. Bet Hero covers 400+ sportsbooks so you always have options.

Tennis is the best sport for arbitrage due to two-outcome markets, tight margins, and extensive global sportsbook coverage. Soccer is second with hundreds of leagues creating price differences across books. Basketball, esports, and table tennis also produce frequent surebets. The more sportsbooks that cover a market, the more likely a pricing gap exists.

You can start with as little as a few hundred dollars, but most serious arbers work with $5,000-$20,000 spread across 10-20 sportsbook accounts. More capital means you can take larger positions and compound faster. The key is having funds available at multiple books so you can act on opportunities the moment they appear.
