Spread Betting

Spread betting is a form of gambling on the outcome of any event where the more accurate the gamble, the more is won and conversely the less accurate the more is lost. A bet is made against a 'spread' (or index), on whether the outcome will be above or below the spread. The amount won or lost depends on the level of the index at the end of the event. The spread represents the index firms' margin.

The concept has a long history in American sports betting and was exported to the United Kingdom in the 1980s. In North America the bettor usually bets that the difference in the scores of two teams will be less than or greater than a value specified by the bookmaker. For example, if a bettor places a bet on an underdog in an American football game when the spread is 3.5 points, he is said to take the points; he will win his bet if the underdog's score plus 3.5 points is greater than the favourite's score. If he had taken the favourite, he would have been giving the points and would win if the favourite's score less 3.5 points was greater than the underdog's score.

Spreads may be specified in half-point fractions to avoid ties, or pushes. The winner of a North American spread bet wins the amount that he has bet, while a losing bettor loses the amount wagered plus the bookmaker's commission, which is commonly known as the vigorish or vig, and is usually 10 per cent of the original wager; in the United Kingdom both sides are held at odds of 9-10. In North American betting a push is treated as if no bet at all had been made, while in the United Kingdom "dead heat" rules apply, resulting in a net loss of
