Totals (Over/Under)

A totals market asks a different question from who wins. The sportsbook posts a number, such as 2.5 goals or 47.5 points, and customers bet whether the actual figure exceeds it. Half-point lines prevent ties; whole numbers can push. Because the market is independent of the winner, it appeals to customers with a view on pace, style or conditions rather than on the outcome itself.

Totals are also where weather, injuries and tactical information often show up first. A forecast of high wind will move an American football total before it moves the spread, and a key defensive absence can move a basketball total sharply. The market extends naturally into player props and team totals, which now form a large part of in-play and same-game parlay volume. For traders, totals and spreads must stay mutually consistent, since an implausible combination of the two is quickly arbitraged.
