Formula

Surebet Check: Sum of (1 / Odds) for all outcomes < 1

ROI = (1 / Sum of Inverses - 1) × 100%

Individual Stake = Total Investment × (1 / Odds_i) / Sum of Inverses

Guaranteed Profit = Total Investment / Sum of Inverses - Total Investment

Frequently Asked Questions

What is a surebet?

A surebet (also called arbitrage bet or arb) is a situation where you can bet on all possible outcomes of an event across different bookmakers and guarantee a profit regardless of the result, by exploiting differences in odds.

How is a surebet different from arbitrage?

They are the same concept. Surebet is the more common term in European markets, while arbitrage betting is the more technical/American term. Both involve backing all outcomes across different bookmakers for a guaranteed profit.

What ROI can I expect from surebets?

Typical surebet opportunities offer 1-5% ROI. Higher margins are rare and tend to disappear quickly. Even small percentages can be profitable with larger investments and high volume.

Can bookmakers ban me for surebetting?

While surebetting is legal, bookmakers may limit or close accounts of suspected surebet bettors. Using multiple accounts, varying stake sizes, and mixing surebet activity with regular bets can help reduce detection risk.
