Surebet & arbitrage software

What is surebet (arbitrage) software?

A surebet, also called an arbitrage or arb, happens when different bookmakers price the same event far enough apart that backing every outcome guarantees a profit. Doing this by hand is slow and the gaps vanish in seconds, so arbitrage software does the heavy lifting: it pulls live odds from hundreds of bookmakers and exchanges, compares every market, and surfaces only the bets where the combined implied probability falls below 100%. That gap, expressed as a percentage below 100, is your guaranteed margin. A 2% arb means that no matter which outcome wins, you collect approximately 2% of your total combined stakes as profit.

The best tools go beyond simple scanning. They add stake calculators, value-bet and middle detection, bookmaker filters, and alerts so you can act before the price moves. For matched bettors and value bettors, the same engines highlight positive expected-value bets by comparing soft bookmaker lines against a sharp reference price from an exchange or a market-maker book.

How surebet software works

Scanners connect to bookmaker and exchange feeds, normalise the odds into a common format, and continuously calculate the implied margin across each market. When the total implied probability drops below 100%, the difference is your guaranteed edge, and the tool shows the exact stakes to place on each side to lock in that return.

Refresh rate, sometimes called latency, is how quickly the scanner detects a price change and updates its display. A tool that refreshes in near-real time gives you a longer window to act before a bookmaker adjusts its line. In practice, an arb appearing with a healthy margin on a fast-refreshing scanner is far more actionable than the same margin on a tool that updates slowly. The fastest commercial scanners pull odds continuously and show you how old each opportunity is, so you can judge whether it is still live before you log in and place the bet.

Account limits and bookmaker rules matter too. Bookmakers use their own monitoring to flag winning patterns, and an account that places too many arbitrage bets in suspicious patterns can be restricted or closed. This is why the better platforms let you filter out books known to restrict winners, and why rounding stakes to natural-looking amounts, a feature some tools include, can extend the active life of your accounts.

What to look for when choosing a tool

Market and bookmaker coverage: more sources mean more opportunities, especially if you bet on niche sports or in a specific country. A scanner covering a wide network of bookmakers will surface more arbs per hour than one limited to mainstream operators.

Refresh speed and reliability: arbs are short-lived, so low latency and accurate, de-duplicated odds protect your profit. Check whether a tool shows the age of each opportunity so you know how long it has been live before you act on it.

Value and middle detection: tools that also find positive expected-value (EV) bets and middles extend your edge beyond pure arbitrage. Value bets require backing one side rather than covering all outcomes, so they carry variance, but they are often easier to place without triggering bookmaker risk alerts.

Free tier versus paid subscription: free scanners typically cover fewer bookmakers, refresh more slowly, and surface lower-margin arbs. Paid tools add faster feeds, broader coverage, real-time alerts, and sometimes dedicated mobile access. For an active bettor the subscription cost is usually recovered quickly, but testing on a free trial before committing is sensible.

Account-longevity features: look for stake-rounding tools, the ability to filter out books known to restrict winners, and guidance on bet placement that extends account life. The scanner is only valuable as long as your bookmaker accounts remain active.

How we rank surebet software

Every tool on this page is scored on the same criteria: odds coverage, scan speed, value accuracy, ease of use, and price-to-value. The ranking is ordered by that overall score. We re-test regularly and adjust positions as features, pricing, and reliability change. For a detailed breakdown of each criterion and how we weight it, see our full rating methodology at /how-we-rate/.

Affiliate relationships do not affect scores or positions. A tool that earns a higher commission does not move up the ranking; one that earns no commission does not move down. The only input that changes a score is real-world performance across our standard test criteria.

Quick comparison: top surebet scanners

Sharkbetting (rated 9.8) is an odds-matching platform built around real-time back-versus-lay comparison across 20-plus sportsbooks, with live liquidity drawn directly from Orbit Exchange, Betfair (via BFB247), and SharkbetX. Its standout feature is showing available liquidity next to each lay price, so you can size your stake before opening a calculator. A free tier is available, and paid plans can be unlocked at no cash cost by generating qualifying activity on Orbit Exchange.

OddsJam (rated 9.7) is the primary scanner for bettors in the United States and Canada. It covers over 150 bookmakers across North America and global markets, and supports arbitrage, matched betting, middle betting, and positive-EV value bets. A free trial is available. The interface can feel information-dense for newcomers, and the higher-tier plans carry a meaningful monthly cost, but the depth of coverage in North American markets is unmatched among the tools we have tested.

BetBurger (rated 9.6) has been running since 2013, is operated by Aspira Limited (licensed in Malta), and scans more than 30 sports. It produces multiple surebet opportunities per minute and lets you filter arbs by ROI percentage, arb age, and start time. The customisable web interface includes push notifications and sound alerts for new opportunities.

RebelBetting (rated 9.2) focuses on pre-match betting and has built a large customer base since its launch in 2008. It is developed by Clarobet AB and covers both arbitrage and value betting. A notable feature is stake rounding, which produces bet amounts that look natural to bookmaker risk teams and helps preserve account longevity.
