Arbitrage
Also known as: Arb, Sure Bet
Arbitrage is placing bets on every possible outcome of an event across different sportsbooks at prices that guarantee profit regardless of result. It exploits pricing disagreements between books rather than predicting outcomes.
Arbitrage uses price gaps between books to guarantee a profit. When one book overprices side A and another overprices side B, a bettor can stake both sides in calibrated proportions and lock in a positive return no matter who wins.
The math is straightforward. For a two-way market, compute the combined implied probability across the best price on each side. If the sum is below 100%, an arb exists. The size of the arb is the gap. Stake allocation: distribute total stake so each side returns the same total amount.
Worked example. NBA game, Team A is +105 at Book 1 and Team B is +105 at Book 2. Implied probabilities: 48.78% + 48.78% = 97.56%, leaving a 2.44% arb. To lock $1000 total return: bet $487.80 on each side. Total stake = $975.60. Profit = $24.40, guaranteed.
Arbitrage is real but operationally hard. Books actively limit or close accounts that arb. Lines move within seconds, so the window is often gone before both legs are placed. Currency conversions, withdrawal fees, and account limits eat into theoretical profit. Most “arb” opportunities at retail US books vanish for any bettor with meaningful volume.
Elite Picks does not surface arbitrage opportunities because the platform isn’t an account-management tool. The model focuses on +EV (a probabilistic edge that pays out over volume) rather than arb (a structural edge that pays out per ticket but invites account scrutiny). Both are valid; they serve different bettor profiles.
Example
Book A offers Team X at +110, Book B offers Team Y at +110. Betting $476 on X and $476 on Y guarantees a return of $1000 either way, against a total stake of $952. Profit: $48, or about 5%.
