Spread Betting Definition

Spread betting, otherwise known as index betting, is a type of unfixed bet that allows gamblers to predict the outcome of a game or match, and then “back” their decision against the spread by the bookmaker. This “spread” refers to a scoring range; if you believe the range is too high or too low you can bet accordingly.


One example can be seen in a Rugby match. Say South Africa beats New Zealand 31 to 18. South Africa’s winning margin is 13 points. If you had bet “lower than 15” for instance then you will have won. The odds will vary from team to team and will be provided by the bookmaker or actual betters on bet trading websites. In terms of index betting, the odds might fall or rise in proportion to the point difference.

Spread Betting Pros and Cons
  • People who are clued up will be able to more consistently win with spread betting as the odds are more in the punter’s favor.
  • It’s possible to trade odds on spread betting on bet trading websites for an easy profit once the game starts.
  • Sometimes the “spread” is limited and the most likely outcome will always have very low odds. This might lead punters to gamble for unlikely outcomes.
