One key point to note on arbitrage betting is that it requires a large bankroll due to the fact the margins are relatively small. In most instances, the margin available for profit using this betting method lies between 2-5%. How much can you make from arbitrage betting The table above shows that if we were to cover all outcomes using a single bookmaker, we would make a loss as the combined market margin is above 100% (shown in red), giving the bookmaker an edge. However, if we back each outcome using the best odds from more than one bookmaker, the combined market margin drops to below 100% (shown in green), producing an arb.
Also consider that the rules between different books may not be the same. One of my favorite sports to bet on is cricket. If the game is shortened due to rain, bookmakers can have different interpretations and rules based on how much the game is reduced. This can lead to an otherwise winning bet voiding, and the losing bet continuing to lose. Make sure you know the rules of the books and sports you are betting, so that you don’t get caught out with an unhedged position. How Arbitrage Betting Works Bookmakers gub accounts in an attempt to ‘punish’ for ‘abusing’ bonuses. Unfortunately, many bookmakers see matched betting as bonus abuse. However, matched betting is a completely legitimate way to use bookie offers.
