The "Free Money" Engine
Arbitrage removes the gamble entirely. By finding scenarios where two sportsbooks disagree on the outcome, you can cover all possibilities and lock in a profit before the game even starts.
Automated Balancing
You don't need to do the math. Just type "I want to bet $500 total" into the toolbar. The app automatically calculates the perfect split (e.g., $255 vs $245) to maximize your return.
Anti-Suspicion Rounding
Betting weird numbers like $143.27 is a red flag to bookies. Our "Smart Rounder" adjusts your stakes to the nearest $1 or $5 to keep your account healthy.
"Fix Mode" Calculation
Already have $50 stuck in a sportsbook? Use "Fix Mode" to tell the calculator to use exactly that amount on Side A, and it will tell you what to bet on Side B to lock in the profit.
Pro Features Only
Because arbitrage opportunities are time-sensitive and highly valuable, this tool is strictly locked to Pro members. It is a professional-grade tool that can pay for the subscription cost in a single day.
Don't Get Limited.
Arbitrage isn't illegal, but sportsbooks hate it. If you bet exact cents (e.g., $153.42) to maximize every penny, you will be flagged immediately.
EdgeSlip's "Stealth Mode" automatically rounds your calculator outputs to look like recreational bets ($150 or $155). We sacrifice pennies of profit to buy you months of account longevity.
The Math Behind Arbitrage
An arbitrage opportunity exists when the sum of the implied probabilities of all outcomes is less than 100%. This typically happens when two sportsbooks have significantly different opinions on a game.
Example:
Book A has Knicks Moneyline at +110 (Implied 47.6%)
Book B has Celtics Moneyline at +105 (Implied 48.8%)
Total Implied Probability = 47.6% + 48.8% = 96.4%.
Because this is less than 100%, a guaranteed profit exists.
Our scanner finds these specific pairs instantly. Use the built-in Arbitrage Calculator to determine the exact stakes needed.
