Arbs

What it is

Arbs are arbitrage opportunities: two or more bets across different books that, when staked correctly, guarantee a profit regardless of outcome. They exist because books disagree on prices, and our scanner catches those disagreements in real time.

When to use it

How to read it

ColumnMeaning
Profit %Guaranteed profit as a percent of total stake (across both legs).
Sport / LeagueWhat event this arb is on.
MarketMoneyline arb, spread arb, total arb, prop arb.
Side A / Side BThe two opposing selections at the two books.
Stake A / Stake BHow much to put on each side to lock in the profit (auto-computed for your bankroll).

Worked example

Example

NHL: Rangers vs Bruins moneyline arb

Side A: Rangers +150 (DraftKings)
Side B: Bruins  -135 (FanDuel)
Bankroll: $1000
Stake A:  $410 on Rangers
Stake B:  $590 on Bruins
Profit if Rangers win:  $410 * 2.50 - $1000 = $25
Profit if Bruins win:   $590 * 1.741 - $1000 = $27
Guaranteed profit ~2.5%

Place both at the same time. Verify both confirmed before celebrating. If one leg moves before you placed it, the arb is gone.

Common mistakes

  1. Treating arbs as risk-free. Books void bets, suspend lines, and limit accounts. Operational risk is real.
  2. Hitting the same arb across multiple promo screens. Books pattern-match. Big arb volume on the same matchup attracts limits.
  3. Forgetting line shop after the first leg lands. If the second leg moves between clicks, recompute or kill the trade.
  4. Over-staking on live arbs. Live odds move in seconds. The arb you saw may already be dead. Smaller is safer.
  5. Ignoring withdrawal friction. Arbs are useless if you cannot get your money out. Test withdrawals on every book first.
