Frequently Asked Questions
What is a surebet?
A surebet, also referred to as an arbitrage bet or arb, arises when you can back every possible outcome of an event across different bookmakers and lock in a profit no matter the result, by capitalising on discrepancies in the odds.
How does a surebet differ from arbitrage?
They describe the same concept. Surebet is the term heard more often in European markets, while arbitrage betting is the more technical, American label. Both rest on backing all outcomes across different bookmakers to secure a guaranteed profit.
What sort of ROI should I expect from surebets?
Typical surebet opportunities deliver an ROI of 1-5%. Larger margins are uncommon and tend to vanish swiftly. Even modest percentages can prove profitable when paired with sizeable investments and high volume.
Can bookmakers ban me for surebetting?
Although surebetting is legal, bookmakers may restrict or close the accounts of those they suspect of it. Spreading activity across multiple accounts, varying your stake sizes, and blending surebet activity with ordinary bets can all help lower the risk of detection.
