Betting arbitrage (“miraclebets”,”surebets”, sports arbitrage) is an example of arbitrage arising on gambling markets due to either bookmakers’ differing opinions on event results or errors. When conditions permit, by placing one bet per every result with different betting companies, the bettor can create a profit whatever the outcome. Mathematically arbitrage occurs when there are a set of chances, which signify all mutually exclusive results that pay most of state space chances (i.e. all outcomes) of the event, whose suggested probabilities add up to less than 1. [1] From the bettors’ slang an arbitrage is frequently referred to as an arb; people using arbitrage are known as arbers. [citation needed]

Arbitrage betting involves relatively large quantities of money, given that 98 percent of arbitrage opportunities return less than 1.2%. [2] The clinic is generally detected immediately by bookmakers, who typically hold an unfavorable view of it, and this can lead to half an arbitrage bet being pinpointed. Arbitrage betting is always insufficiently rewarding due to detection, unreliable gambling websites, restricting of bets, hackers, and scammers that use high percent arbitrages to deceive bettors into supplying security credentials. [citation needed]

Bookmakers generally disapprove of betting arbitrage, and restrict or shut the accounts of those who they suspect of participating in arbitrage betting. [citation needed] Although arbitrage gambling has existed since the beginnings of bookmaking, the development of the world wide web, odds-comparison sites and betting exchanges have produced the practice simpler to perform. On the flip side, these changes also made it easier for bookmakers to keep their chances in accord with the marketplace, because arbitrage bettors are basically acting as market makers.

In Britain, a practice has developed in which highly experienced”key men” employ other people to put bets on their benefit, in order to prevent detection and boost accessibility to retail bookmakers and permit the financiers or crucial arbitragers to remain in a computer to keep an eye on market movement.

Arbitrage is an extremely fast-paced procedure and its effective performance requires lots of time, expertise, dedication and discipline, and especially liquidity.
