Betfair Lay Betting - What is lay betting?
We cast our eye over the Lay Betting option with Betfair.
Why Lay Bet With Betfair
Sometimes it can be easier to find a horse or sporting team that won't win opposed to finding the actual winner of the race or match itself.
Can't find the winner but you're confident that a certain candidate or even multiple runners can't win? Lay Betting with Betfair is your answer.
What is a Lay Bet?
Lay betting is completely unique to Betfair Exchange. When you place a Lay bet you are betting on an outcome NOT to happen.
You are effectively offering a price that other users can Back Bet with you.
Examples of a Lay Bet include:
- Angel Capital NOT to win the Australian Guineas
- Carlos Alcaraz NOT to win the French Open
- Penrith Panthers NOT to win the 2025 NRL Premiership
What do the Odds Represent?
The odds you will see in the pink column of the market view, the Lay price, is the price that someone wants to place a Back Bet at but is yet to be matched (an offer).
You have the opportunity to take this offer straight away rather than putting your own odds up. Alternatively, you can enter your own odds, and see if it gets matched.
What are the Key Components of Lay Betting?
The three main cores of a Lay Bet are:
- Lay odds - the odds which you are prepared to give someone wanting to place a Back Bet.
- Backers Stake - the amount you are prepared to let the backer bet with you. This is your potential winnings.
- Liability - (Lay Odds) x (Backer’s Stake) – (Backer’s Stake). This is the amount you are risking.

An example on Golf:
You don’t think Jordan Spieth can win the US Masters and you see the Lay odds are $8. You decide to Lay Jordan Spieth for a Backers Stake of $50.
This means your liability is $8 x $50 = $400 – $50 = $350. So if Jordan Spieth doesn’t come first, you will make $50 (the Backers Stake).
If Jordan Spieth does win, you lose $350.
An added benefit of lay betting with Betfair is the ability to ‘trade out’ of an earlier bet that you may have had.

Betting exchanges allow users the flexibility to find odds and markets they want rather than risking a bookmaker who can dictate the stake and price for a selection.
