The main football markets
Over/Under goals (totals)
5 min
The Over/Under market ignores who wins and asks a different question: how many goals will the match contain in total? It's one of the most popular football markets.
How the line works
The book posts a number — most commonly 2.5 — and you bet whether the combined goals finish over or under it.
- Over 2.5 wins if the match has 3 or more goals (e.g. 2–1, 3–0, 2–2).
- Under 2.5 wins if it has 2 or fewer (e.g. 1–0, 1–1, 0–0).
The .5 is deliberate: with a half-goal line there's no such thing as landing exactly on it, so there's never a push. Whole-number lines like 2.0 can push — if exactly two goals are scored, your stake is returned.
Why 2.5 is the anchor
Because the average league match lands near 2.5–2.8 goals, the 2.5 line sits right at the coin-flip and is the most traded. Books also offer 1.5, 3.5 and beyond for higher- or lower-scoring expectations.
What drives the number
Totals are about attacking quality, defensive solidity and game state. Two free-scoring teams with leaky defences push the line up; two cautious, defensive sides pull it down. League context matters too — some leagues simply average more goals than others. This is exactly what a goal model estimates, which we cover in Chapter 4.
