Understanding Back and Lay Bets
Back and lay betting are fundamental concepts in when learning about sports betting, particularly when using betting exchanges.
These two types of bets form the foundation of how betting exchanges operate and provide bettors with unique opportunities to profit from sporting events.
A back bet is the more conventional type of bet that most people are familiar with. When you place a back bet, you are betting on a particular outcome to happen.
For example, if you back Man City to win a soccer match, you win your bet if Man City wins the game. This is essentially what betting means in the traditional sense.
A lay bet is the opposite. When you lay a bet, you are betting against a particular outcome happening.
Using the same example, if you lay Man City to win, you are essentially betting that Man City will not win the match — meaning you win if they either lose or draw.
Lay betting is a unique feature of betting exchanges and is not typically available with traditional bookmakers.
The table below provides a basic summary of each bet type:
Aspect | Back Bet | Lay Bet |
---|---|---|
Position | Betting for an outcome | Betting against an outcome |
Role | Acting as bettor | Acting as bookmaker |
Profit | (Stake * Odds) - Stake | Backer's Stake |
How Betting Exchanges Work
Betting exchanges operate on a peer-to-peer model, allowing bettors to bet against each other rather than against a bookmaker.
This system facilitates both back and lay betting, creating a more dynamic betting environment.
Understanding how betting exchanges work is essential for anyone looking to engage in back and lay betting.
On a betting exchange like Betfair, every betting market has two sides: the back side and the lay side. Bettors can choose to either back or lay an outcome at the odds available, or they can offer their own odds. When a backer's odds match a layer's odds, the bet is instantly matched, and the exchange takes a small commission on the winner's profit.
The betting exchange acts as an intermediary, holding the stakes and distributing winnings after the event concludes.
This system allows for more flexibility in betting, as bettors can request better odds than those currently available, or even trade their position before the event ends.
For example, in a football game between the Kansas City Chiefs and Chicago Bears, you might see odds of -150 for the Chiefs to win. On a betting exchange, you could choose to back Kansas City at these odds, or you could offer to lay the Chiefs at slightly higher odds, hoping that someone will match your bet.
