What Is A Lay Bet?
When you lay a bet, you are offering odds on an outcome not occurring, and someone else backs that outcome by matching your offer. If the outcome does not happen, you keep their stake. If it does happen, you pay them out.
🔒 How A Lay Bet Works
In matched betting, a back bet (betting for an outcome at a bookmaker) is paired with a lay bet (betting against that same outcome on an exchange). Matching the two locks in a predictable result no matter what happens in the event.
Lay bets are placed on peer-to-peer exchanges such as Betfair, rather than with traditional bookmakers, who only accept back bets.
📋 Key Terms
| Term | What It Means |
|---|---|
| Lay Odds | The price at which you are betting an event will not happen. Usually shown in pink on exchanges. |
| Lay Stake | The amount you would win if the outcome does not happen. This is what the backer is risking against you. |
| Liability | The cash you need in your exchange account to pay the backer if your lay bet loses. |
📈 Example
Say you lay “Team A to win” at odds of 3.00 with a $50 lay stake:
- If Team A loses or draws, you keep the backer’s $50 stake as profit.
- If Team A wins, you pay the backer $100, which is their stake multiplied by the odds, minus their original $50, giving a liability of $100.
❓ Frequently Asked Questions
Is a lay bet the same as a back bet?
No. A back bet wins if the outcome happens. A lay bet wins if the outcome does not happen. They are opposites, and matched betting uses both together.
Where can I place a lay bet?
Lay bets are placed on betting exchanges, such as Betfair, rather than with standard bookmakers.
What happens to my liability if I lay a bet?
Your liability is held in your exchange account until the event finishes. It is released back to you if the outcome you laid against does not happen.
