Arbitrage

Opposite sides priced so every outcome profits — stake plan for $100 shown

How the Arbitrage board works

An arbitrage exists when two books price opposite sides of a market so far apart that the implied probabilities add up to less than 100%. Bet both sides in the right proportion and the payout is the same whichever side wins, and larger than the total staked.

The board lists every one TrueEdge finds, with the margin, both books and prices, and the stake on each side for the amount you want to put down.

Exchange legs are priced after fees, and the board can be limited to books licensed in your state.

Worked example

Book A offers Team X at +110 (decimal 2.10). Book B offers Team Y at -102 (decimal 1.9804).

Implied probabilities: 1 ÷ 2.10 = 47.62% and 1 ÷ 1.9804 = 50.50%, which add to 98.11%. The 1.89-point gap is the arbitrage.

With $1,000 to stake: $485.34 on Team X and $514.66 on Team Y.

Either result returns about $1,019.21 — roughly $19 of profit, a 1.9% return, provided both bets stand at those prices.

Frequently asked questions

Is arbitrage betting profitable?

Each arbitrage returns a small, known margin if both bets stand at the prices you took. The risks are a price moving before your second bet, a book voiding a bet, stake limits, and books settling the same event differently.

How are the arbitrage stakes calculated?

Each side's stake is proportional to its implied probability, so both outcomes pay back the same amount. TrueEdge solves the split for the total you enter.

Why do arbitrage opportunities disappear so quickly?

Because the book that is out of line corrects its price, often within seconds to minutes. That is why the live board refreshes continuously.
