Why Arbitrage
What Arbitrage does for you
Spot price discrepancies between sportsbooks and bet opposite sides of the same market. When both sides are accepted at the listed prices, the stake split returns a profit whichever side wins. The board is built for speed, with a stake calculator and deeplinks that open both books at once.
Live board of opportunities
Scan pregame and live price discrepancies across sportsbooks in real time. Every row shows the ROI %, both sides with odds and books, and the calculated profit.
Arb calculator & auto stake sizing
Enter your total bet size and the calculator splits it across both books. See each stake, the payout, the profit, and ROI %, then apply the split to the whole table.
Settings & filters
Set min/max ROI %, total stake, market types (player props and game lines), min liquidity, leagues, and the books you actually have accounts with.
Fast execution
Deeplinks open both sportsbooks at once so you can place both legs before the prices move, on desktop or mobile.

FAQ
Common questions
Quick answers about Arbitrage.
Is arbitrage risk-free?
The math locks in a return only when both sides are accepted at the listed prices and settle under compatible rules. Prices can move, limits can apply, and books can void bets, so place quickly and check both legs.
Which plan do I need?
Arbitrage is included with Grinder and Syndicate, with pregame and live arbs and auto-refresh. Free and Scout accounts see a limited preview.
How does the arb calculator work?
Enter your total bet size and the calculator tells you how much to stake on each side at each book. It shows the total payout, profit amount, and ROI %.
How fast do arbs disappear?
Often within seconds as books adjust their lines. That's why the board auto-refreshes and deeplinks open both sportsbooks at the same time.
Can I filter by market type?
Yes. Filter between player props and game lines, and set min/max ROI %, total stake, min liquidity, leagues, and books.
