How many bookmaker accounts do I need?

An arbitrage needs both of its legs to be at YOUR bookmakers. With three accounts you will watch most opportunities pass by because one side sits at a book you do not have. Every account you add multiplies the combinations, and the effect compounds fast in the beginning.

Why ten, not three and not thirty #

The curve flattens. Going from 3 to 10 accounts multiplies your reachable arbs many times over; going from 20 to 30 adds little, because the extra books are smaller, slower and rarely on the best side of a price. Meanwhile every account is real overhead: KYC documents, deposits parked, terms to remember, withdrawal rules.

Ten well-chosen books cover the bulk of what a scanner like OddStorm will show you day to day. Grow past that only when your bankroll and routine are ready for it.

Which ones to open first #

Order matters more than the exact list:

• Sharp anchors first: Pinnacle plus a betting exchange (Betfair). They sit on one side of a huge share of arbs, they take large stakes, and they do not limit winners.
• Then the biggest soft bookmakers licensed in your country: the household names with big turnover. Big books move slower and produce the pricing disagreements you feed on.
• Then one or two regional specialists your market favors. Local books often lag international odds, which is exactly what an arber wants.

Check each candidate against our live supported list first: a bookmaker OddStorm does not scan cannot bring you scanner arbs, however good it is otherwise.

Get verification out of the way on day one #

Every bookmaker will eventually demand identity documents (KYC), usually exactly when you try to withdraw. Do not let that surprise you mid-arb:

• Upload your documents immediately after registering, before the first deposit if the book allows it.
• Use identical personal details everywhere: name as in your ID, one address, your own payment methods. Mismatches freeze accounts.
• Do a small test deposit AND withdrawal early. A book that pays you EUR 20 smoothly will pay EUR 2,000.

When to grow the list #

Add accounts when you keep seeing good arbs die because one leg is at a book you lack, and your existing accounts are verified, funded and routine. That is a signal of lost profit, and it names the exact bookmaker to open next: the one that keeps appearing on the missed side.

Where to go next #

With accounts in place, the next questions are how much money to spread across them and how to behave so the soft books keep you around.
