Can sportsbooks change odds after you place a bet?
Understand sportsbook odds policies and how arbitrage betting secures guaranteed profits without risk from changing odds.
Can sportsbooks change odds after you place a bet?
Once you place a bet, sportsbooks do not change the odds on that specific wager; the odds are locked in at the time of your bet confirmation.
Sportsbooks can adjust odds before you place a bet to manage risk and balance action, but after your bet is accepted, the original odds remain fixed regardless of later changes.
Arbitrage betting removes the uncertainty of changing odds by finding guaranteed profit opportunities across different sportsbooks, ensuring the odds you see are the odds you get.
How Sportsbooks Set and Adjust Odds
Sportsbooks set odds based on statistical models, expert analysis, and market demand. They monitor betting patterns and may adjust odds to balance the book and reduce potential losses. These adjustments happen in real-time before bets are placed to attract bets on both sides of an event.
- •Odds are influenced by team/player performance, injuries, and other factors.
- •Bookmakers adjust odds to ensure a balanced book and guaranteed profit via the vig or juice.
💡Odds Adjustment Before Bet Placement
If too many bets are placed on one side, a sportsbook may lower those odds to discourage further bets and raise the odds on the other side to attract action.
If Team A's odds change from +150 to +130 before betting closes, new bets will reflect the +130 odds, but existing bets keep their original +150 odds.
Can Sportsbooks Change Odds After You Place a Bet?
After your bet is accepted, sportsbooks do not retroactively change the odds on that wager. Your bet is locked in with the odds at the time of acceptance. This protects bettors from unfair changes and ensures clarity on potential payouts. However, sportsbooks continue to adjust odds for new bets based on evolving circumstances.
- •Odds are fixed for your individual bet once placed.
- •Subsequent odds changes affect only new bets, not existing ones.
💡Fixed Odds Guarantee
If you place a bet at odds of +120, even if the odds change to +110 minutes later, your payout is calculated using the original +120 odds.
A $100 bet at +120 odds returns $220 regardless of any later odds adjustments.
Exceptions and Special Cases
While most sportsbooks lock odds after bet placement, some live betting markets allow odds to fluctuate continuously. In these cases, bets are matched instantly at the current odds. Additionally, if a bet is voided due to event cancellations or errors, the wager is refunded. Arbitrage betting helps manage risks from these exceptions by focusing on guaranteed outcomes rather than fluctuating odds.
- •Live bets have dynamic odds but are matched instantly at accepted odds.
- •Void bets result in refunds, not adjusted odds.
- •Arbitrage betting circumvents risks by capitalizing on fixed discrepancies.
💡Live Betting Odds Fluctuation
In a live match, odds change every few seconds, but your bet is matched at the exact odds when placed. If the market moves after, it does not affect your settled bet.
A live bet accepted at -110 odds pays out based on that value regardless of subsequent changes.
Challenges in Traditional Sports Betting
Traditional sports betting carries risks such as changing odds before placing a bet, potential bookmaker bias, and market volatility that can reduce potential profits. Bettors often struggle to time bets perfectly to capture the best odds. Arbitrage betting offers a solution by identifying price differences across sportsbooks, locking in profits regardless of individual odds movements.
- •Timing bets to get the best odds is difficult and risky.
- •Market volatility can erode value quickly.
- •Bookmaker adjustments can disadvantage bettors.
💡Missed Opportunities Due to Odds Changes
A bettor targets +200 odds but delays placing a bet, and the odds drop to +170, lowering potential profit.
This uncertainty is eliminated with arbitrage betting, which locks in profit by exploiting fixed price discrepancies.
How Arbitrage Betting Addresses Odds Uncertainty
Arbitrage betting involves placing bets on all possible outcomes across different sportsbooks where odds differ sufficiently to guarantee a profit. This eliminates the risk of odds changing after placing bets because arbitrage requires locking in all bets simultaneously.
