Yes, odds can change after a bet is placed. This is a common occurrence in sports betting and other forms of gambling where odds are set based on various factors such as the likelihood of an event occurring, the amount of money wagered on each outcome, and new information that could affect the outcome of the event.
Here are a few reasons why odds might change after a bet is placed:
1. **Market Movement**: If a large amount of money is bet on one side of an event, the bookmaker or sportsbook may adjust the odds to balance out the action. This is known as “line movement.”
2. **New Information**: New developments, such as injuries to key players, weather conditions, or changes in team strategy, can cause the odds to shift.
3. **In-Play Betting**: In live betting, odds change dynamically as the event unfolds. For example, in a football match, the odds can change after a goal is scored or a red card is given.
4. **Market Efficiency**: As more information becomes available to the public, the collective betting behavior of individuals can lead to more accurate odds, causing them to change.
5. **Bookmaker Strategy**: Bookmakers may adjust odds to attract more bets on a particular outcome to ensure they make a profit regardless of the event’s outcome.
It’s important to note that once a bet is placed, the odds at the time of the bet are locked in for that particular wager. If the odds change later, it does not affect the payout for the original bet. The bettor will receive the payout based on the odds in place when the bet was made, assuming the bet is successful.
