Short version: you have placed the bookmaker bet and the exchange price has moved against you before you got the lay on. You are currently unhedged. The right move is almost always to lay at the new price and accept a bigger qualifying loss — the cost of waiting is that the position stays live, and live positions are how matched bettors lose real money.
What has actually happened
Exchange prices move continuously as people back and lay. Between you clicking confirm at the bookmaker and reaching the exchange, the lay price drifted up. The back and lay are no longer close, so covering the bet now costs more than the calculator told you it would.
Nothing has gone wrong with your account or the offer. This is normal market behaviour, and it happens most around team news, in the last hour before kick-off, and on thinly traded markets.
Your three options
1. Lay at the new price — usually right
Recalculate with the current lay odds and place it. Your qualifying loss will be larger than planned — perhaps £1.50 instead of 30p — and that is the whole cost. The offer still works, the free bet is still worth far more than the difference, and you are covered.
Run the numbers rather than eyeballing them. Our matched betting calculator will show the new lay stake and liability in a few seconds, and seeing the actual figure usually settles the decision.
2. Wait for the price to come back — rarely right
It might. It might also keep moving. While you wait you are holding an unhedged bookmaker bet, which means you are gambling on the outcome — the exact thing the lay bet exists to prevent.
There is a narrow case for waiting: the market is liquid, kick-off is hours away, and the move looks like noise rather than news. Even then, set yourself a price and a time at which you will lay regardless, and stick to it. “I’ll leave it and see” is how a 30p qualifying loss becomes a £40 one.
3. Lay part of it now — the middle ground
Lay enough to cover most of the exposure at the current price, and leave a smaller order at the price you wanted. You cap the damage while keeping some chance of the better fill. This is more fiddly than it is worth on a £10 qualifying bet, but it makes sense on a large free bet where the difference is real money.
When the move is large
Occasionally the price will have moved so far that laying locks in a loss bigger than the offer is worth. At that point do the arithmetic properly rather than reacting:
- Work out the guaranteed loss if you lay now.
- Work out what the offer is actually worth — a £30 stake-not-returned free bet is worth roughly £21 to £24 once extracted, not £30.
- If the loss is smaller than the offer’s value, lay it and move on. You are still ahead.
- If it is larger, you have a genuine choice between a known loss and an open gamble. Take the known loss. The alternative is not a strategy, it is hoping.
Stopping it happening again
- Have the exchange open before you place the back bet. Two tabs, exchange loaded, lay stake already calculated. The whole sequence should take seconds.
- Check there is enough money available at the price you need before backing, not after. A price you cannot get matched at is not a price.
- Avoid the last few minutes before kick-off unless the offer requires it. Prices move fastest exactly when you have least time to react.
- Prefer liquid markets. Match odds on a major fixture barely moves for a £10 bet. An obscure market can jump on a single order — our exchange comparison covers where the liquidity actually is.
If the problem is that your lay will not match at all rather than that the price moved, that is a different situation — see what to do when a lay bet will not match and partially matched lay bets.
