Odds can seem to shift at the worst moment, especially if you are weighing up a bet. It is natural to ask what happens if the price moves after you place your potential stake, and whether that affects what you might be paid.
With betting taking place both online and in shops, it could help to know how odds updates actually work. There are also consumer protection rules in the UK that shape how operators handle price changes.
Here is a clear look at what really happens when odds move, and what it means for bets that are already on. Read on to learn more.
Can Bookies Change Odds After Placing a Bet?
If your bet is accepted, the odds shown on your slip are the ones that apply to that wager. That price is the basis for any payout if your bet wins. If the market shifts after you have confirmed, those changes only affect new bets placed after the update, not yours.
Bookmakers do update prices throughout the day. They react to fresh information, trading volumes and market moves. Online, you may see settings like bet confirmation or accept odds changes. These give you control over whether you want your bet to proceed if the price moves just before you confirm. A quick glance at the slip before you click confirm could be worthwhile.
In shops, the current price is printed on your slip and staff will flag any difference before taking payment.
If you do decide to try your hand at the bookies, remember to do so responsible and within your means; never wager more than you can afford to lose.
How Betting Odds Work Before and After You Place a Bet
Before you potentially confirm, the price you see reflects how likely the bookmaker rates each outcome and what they are prepared to pay if that outcome wins. For example, a favourite might be 2/5 and an underdog 5/1. The shorter price suggests a higher estimated chance and a lower return per pound staked, while the longer price suggests a lower estimated chance and a higher return per pound.
Prices can move right up to the point of acceptance. Team news, injuries, weather, tactical changes or weight of money can all prompt an update. In a shop, screens and printed slips show the latest figure before you hand the bet over. Online, you may get a prompt if the price changes while you are building your bet.
If the operator accepts your bet, your price is fixed for that slip. As explained above, later market movements do not alter the settlement terms for that specific wager.

Why Do Bookies Change Odds?
Price changes are part of how bookmakers manage risk and respond to information. Three common drivers are:
- Balance of money. If a large volume of stakes lands on one side, odds may shorten for that outcome and lengthen for others to even out exposure.
- New information. A striker ruled out in the warm-up, a change in starting line-ups or a sudden downpour can shift the estimated chance of each result.
- Market competition and models. Operators use trading teams and pricing models, and they also watch competitors. If the wider market moves, an individual firm may adjust to stay aligned.
You will often hear the terms shorten and drift. Shorten means the price moves in, for example from 2/1 to 6/4. Drift means it moves out, for example from 6/4 to 2/1. These moves do not change the terms of bets that have already been accepted, but they do shape the prices offered to anyone betting next.
Do Changed Odds Affect Bets That Are Already Placed?
No. Once your bet is processed, your potential return is calculated using the odds on your slip at the point of acceptance. If the price shifts afterwards, only future bets are affected.
If you want to double-check, look at your bet receipt in your account history or the paper slip from the shop. That shows the stake and the exact price that will be used for settlement.
What Happens If Odds Change While a Bet Is Being Processed?
Prices can move quickly, especially around kick-off or major announcements. Online, most sites show a prompt if the price changes between selection and confirmation. You can usually accept the new odds or cancel before anything is finalised. Your bet only goes through once you confirm at the updated price.
In a shop, if the price differs from what you saw when you filled in the slip, staff will confirm the current odds before taking payment. That way you know exactly what you are agreeing to before the bet is accepted.
The key point is that a bet is not confirmed until both you and the operator agree to the live price at that moment. After that, your odds are locked for that slip.
Can Bookies Cancel a Bet After Changing the Odds?
Bookmakers are expected to honour accepted bets at the price shown on your receipt. Cancellations after acceptance are rare and usually relate to a clear and obvious mistake, often called a palpable error. A typical example would be a misplaced decimal that lists 100/1 where 10/1 was intended, or a technical fault that displays the wrong market.
If a bet is voided for a valid reason, the operator should explain what happened and refund your stake if appropriate. Details of how these situations are handled are set out in the site’s terms and help pages, and customer support can clarify the decision.
For most bets, the process is straightforward. You take a price, the bet is accepted, and it settles at those odds, regardless of how the market moves later. Always keep responsible gambling practises in mind.
