The Scripted Guide to Laying the Bet: Play the Villain
Lay betting does not involve predicting which teams will win.
Lay betting is actually finding a selection that is priced above its true value (overpriced) and selling this bad bet to the general public.
Understanding how a bookmaker thinks helps you to understand lay betting.
In this guide, we cover what lay betting is, how to use exchanges for lay betting, why favorites are typically the most profitable lays, and how to effectively manage your risks to survive long enough to collect your winnings.
What Is Lay Betting?
Lay betting means betting against a selection.
Instead of betting that a team will win, you bet that they will not win.
When you place a lay bet on a betting exchange, you are acting as the bookmaker. You accept another bettor’s wager and agree to pay out only if they are right.
If they’re wrong, you keep their stake.
Backing vs Laying: The Fundamental Difference
Backing (traditional betting):
You bet on something to happen.
Laying (exchange betting):
You bet on something not to happen.
| Role | Outcome |
|---|---|
| Backer | Limited upside, total loss if wrong |
| Layer | Small profit, larger defined risk |
Backing is guessing outcomes.
Laying is pricing mistakes.
How Lay Betting Works in Practice
Example: Laying Arsenal to win
- You lay Arsenal at odds of 2.00
- Another bettor backs Arsenal
- You accept their bet
Outcomes:
- Arsenal wins → you pay the payout
- Arsenal draws or loses → you keep their stake
You don’t need the underdog to win.
You only need the favourite to fail.
Stake vs Liability: The Most Important Concept in Lay Betting
This is where most beginners get wiped out.
When you lay a bet, your stake is your profit, but your liability is your risk.
The Golden Rule
Liability = (Odds − 1) × Stake
Example:
- Lay odds: 10.0
- Stake (profit): £10
- Liability (risk): £90
You are risking £90 to win £10.
If you don’t understand this relationship, do not lay bets yet.
Why Favourites Are Often the Best Lay Bets
Public money distorts prices.
Popular teams, star players, “must-win” narratives, and televised matches attract emotional betting. Odds shorten. Margins disappear.
When you lay a favourite:
- You don’t need them to lose
- Draws work in your favour
- Late chaos benefits the layer, not the backer
This is why professional traders focus on short-priced favourites, not longshots.
Liquidity: Why Some Lay Bets Don’t Get Matched
Lay betting only works if someone is willing to take the other side.
Liquidity is the amount of money available at a given price.
If there isn’t enough:
- Your bet won’t be matched
- Or it will be partially matched
- Or it will get matched later at a bad time
Rule:
Never force a lay in a thin market.
Unmatched Bets: The Silent Risk
An unmatched lay bet is not active.
This creates two dangers:
- The event starts and nothing happens
- The bet gets matched after a goal, red card, or momentum shift
Best practice:
- If it doesn’t match immediately, adjust or cancel
- Never leave ghost orders sitting unintentionally in-play
If it’s not matched, you are not the bookmaker yet.
Commission: The Hidden Cost of Lay Betting
Betting exchanges charge commission on net winnings.
This directly affects profitability, especially on low-margin lays.
Always factor commission into:
- Expected value
- Long-term strategy
- Favourite lays with small edges
Lower commission helps, but liquidity matters more.
Risk Management: Thinking in Exposure, Not Bets
Professional layers don’t think in “bets won or lost.”
They think in liability exposure.
Key principles:
- Never risk more than a small % of bankroll on one liability
- Avoid stacking correlated lays
- Prioritise survival over aggression
One badly sized lay can erase weeks of progress.
Where to Lay Bets
Lay betting is only possible on betting exchanges.
The main platforms are:
- Betfair
- Smarkets
- Matchbook
- Betdaq
Choose liquidity first. Commission second.
Lay Betting FAQ (User-Facing)
What does it mean to lay a bet?
It means betting against a selection. You profit if it does not win.
Is lay betting riskier than backing?
Only if you ignore liability. With proper sizing, risk is controlled and visible.
Can beginners use lay betting?
Yes, but only after fully understanding stake, liability, and liquidity.
Why do lay bettors focus on favourites?
Because favourites are often overpriced due to public money and media bias.
Do I need the underdog to win?
No. A draw or loss both pay the layer.
What happens if my lay bet is unmatched?
It is inactive. You have no exposure unless it gets matched.
