How Arbitrage Works

1. Books disagree. Every sportsbook sets its own prices. Now and then two of them disagree far enough on the same game that the best price on each side adds up to less than 100 percent.
2. You bet each side. Split your stake so every outcome returns about the same amount. Each card shows the split.
3. The result stops mattering. Whoever wins, the winning bet pays back more than both bets cost. It is arithmetic, not a prediction, so you can check it with a calculator before risking anything.

Sports with a draw: a no-draw bet covers both teams but not the draw. If the match ends level, both bets lose, so it is a bet that the game will not be drawn, not an arb. Each card shows the draw chance it breaks even at. Arbs marked guaranteed cover every outcome.

What it takes: funded accounts at two or more books, money tied up on both sides until the game settles, and the speed to get both bets down before a price moves. Check both numbers are still there before you place the second bet. Books also tend to limit accounts that only ever arb. None of that changes the math, but it does mean this is work rather than a button.
