The best bookmakers for arbitrage betting — ranked by real data
Every "best bookies for arbing" list on the internet is someone's opinion. This one isn't. Our scanner logged 791 real arbs between April and September 2026 — so we simply counted which bookmakers appeared in them. If you're deciding which accounts to open first, open the ones that actually show up.

Counted from our scanner's log, 5 April – 30 September 2026. An "appearance" means the bookmaker priced at least one leg of a locked-profit arb. We've left out 109 arbs we now treat as stale prices: gaps of 4.5% or more between two soft bookmakers, with no exchange involved. The scanner holds those back from subscribers too.
Why exchanges dominate the top of the table
Three of the top four are betting exchanges, and that's no accident. An exchange's prices come from other punters, so they move faster than any bookmaker's — and whenever a slow bookmaker lags behind the market, the exchange is the other half of the arb. Two structural advantages make exchanges the foundation of any arbing setup:
- They never limit winners. Exchanges earn commission on your winnings — they want you to win. Your exchange accounts are the one part of your toolkit that lasts forever.
- They're half of most arbs. Back at a soft bookmaker, lay at the exchange — the classic back/lay arb. In our data an exchange was one leg of 83% of arbs.
Commission matters when comparing them: Matchbook and Smarkets charge 2% of net winnings, Betfair 5% (negotiable with volume). Our alerts already account for commission in every profit figure.
The soft bookmakers worth opening
BoyleSports is the standout — third overall and by far the most arb-prone traditional bookmaker in our data, pricing aggressively on tennis, cricket and football. 888sport, Betway and Paddy Power follow, close together. The pattern from 20 years inside a bookmaker: brands that recruit customers with big prices produce the most arbs, because marketing sets their odds as much as the trading desk does.
Which accounts should you open first?
- Foundation (open all three): Betfair Exchange, Matchbook, Smarkets — the never-limited backbone
- First soft books: BoyleSports, 888sport, Betway — the top of our leaderboard
- Then add: Paddy Power, William Hill, Unibet, Casumo — each extra account catches more alerts
You don't need all 20+ books we scan. Those first six accounts would have let you place about 4 in 10 of our 791 arbs in full; adding Paddy Power, William Hill and Unibet takes it to about 6 in 10. Add more as your bankroll grows.
A note for Irish readers
Every bookmaker in the table above is licensed in Ireland except Grosvenor, which is UK-only (as is Virgin Bet, further down the list). BoyleSports and Paddy Power are Irish companies to begin with. The full rundown is in our arbitrage betting in Ireland guide.
Keep your accounts alive
Soft bookmakers do eventually restrict arb accounts — it's the cost of doing business. How fast that happens is largely under your control: stake in round numbers, don't only bet arbs, and spread your action. We wrote the insider's version in how bookmakers spot arbers.
