Arbitrage Friendly Bookmakers
Which ones are arbitrage friendly?
Arbitrage friendly bookmakers are all sharp bookmakers, betting exchanges and almost all Asian bookmakers. They will never limit you or close your account for betting on sport arbs. Exactly the opposite - their odds margin is lower than soft bookies and they welcome arbitrage bettors. Examples for arb friendly bookies are: Pinnacle, 188bet, SBObet, 12bet, Betfair Exchange, Matchbook, Smarkets, Cmd368, Dafabet, Ibcbet and etc. The most famous and reputable one from the mentioned is Pinnacle.
Why are they so positive about arbers?
Sharp bookmakers are operating in a different way than the soft bookmakers (soft bookmakers will do anything to block you if they suspect you are arbing). They count on a high volume of bets with a low margin, which means lower risk for losses and higher odds. Their odds are moving automatically depending the total placed bets and amount on each outcome for the event. Low margin means better value for you, so both you and the bookie is happy at the end. Margins is a complicated thing for a newbie to understand but here is one good article in Pinnacle, which describes it very well - odds margin or in the unit "What is Odds Margin?". Examples for soft bookmakers are: Bet365, Bwin, William Hill, Tempobet, Marathonbet and etc. Almost all Asian bookies are sharp bookmakers.
What about betting exchanges?
Betting exchanges literally don't care if you are arber or not. They are taking up to 6% commission from your winnings and they don't care the way you will win. The most famous betting exchange is Betfair.
We suggest you consider Pinnacle as a "must have" on your list with bookmakers. It will never limit you or close your account. Arbs between sharp bookmakers are really rare and disappear fast, so soft bookmakers are also required as 99% of the arbs are between sharp and soft bookies.
