4-way arbitrage explained

A 4-way arbitrage covers a market with four possible results. These show up in markets such as some Asian handicap lines, grouped result markets, or four-bucket correct-score splits. With four outcomes there is more to balance, but the principle is identical: if the four best prices give a sum of inverses below 1, the profit is guaranteed.

How the stakes are balanced

The calculator computes V = 1/odd₁ + 1/odd₂ + 1/odd₃ + 1/odd₄, then divides your stake so each outcome returns the same payout. Enter all four odds above and adjust the amount — the per-bet stakes and profit update instantly.

Frequently asked questions

When do 4-way arbitrage bets occur?
When a market splits into four outcomes — for example certain Asian handicap lines, combined result groups, or four-way correct-score buckets across different bookmakers.
Is a 4-way arb harder to find?
They are rarer than 2-way or 3-way arbs, but they exist whenever the four best prices together give a sum of inverses below 1.
Can I mix bookmakers?
Yes. You will normally take each of the four prices from whichever bookmaker offers the most, then enter them all here.
