How Arbitrage Works
When you bet both outcomes at the same sportsbook, the vig (house edge) ensures you lose money.
Sportsbooks are built to profit no matter who wins.
104 -115 100 -105 +$90 -$100 -$104 +$95Different sportsbooks post slightly different odds. Occasionally, a perfect combination appears.
With the right books, odds, and bet sizes, either outcome returns a profit at the listed odds.
80 +140
100 -105 +$112 -$100 -$80 +$95Each arbitrage is small — but there are hundreds every day.
Estimates based on your inputs. Actual results vary by experience, bankroll management, and market conditions.
A quick example
Book A has Team X at +110. Book B has Team Y at +105. Bet $49.40 on X and $50.60 on Y ($100 total). Whichever team wins, you get back about $103.73 — a 3.7% return. The tool finds these gaps and calculates the stakes for you.

Arbitrage works on math, but real-world execution matters. Here's what experienced arbers manage.
Odds move
Lines can change before you place the second bet. Place both sides quickly, and re-check the odds before you confirm.
Voids and rule differences
Books settle some markets differently (e.g. player not playing). Stick to markets where both books use the same rules.
Account limits
Some sportsbooks limit accounts that win consistently. Spreading action across many books helps.
