As of my last update, on DraftKings Sportsbook, once a bet has been placed, it generally cannot be canceled. Once you confirm and submit your bet, it is considered final and will stand as is, win or lose.
However, there are some specific scenarios where a bet might be voided or canceled by DraftKings:
1. **Technical Issues:** If there is a technical issue with the platform that affects the bet, DraftKings may void the bet.
2. **Rule Violations:** If a bet is placed in violation of the sportsbook’s rules, it may be canceled.
3. **Game Cancellation:** If the event you bet on is canceled or postponed and does not occur within a specified time frame, the bet may be voided.
4. **Line Errors:** If there is a mistake in the odds or lines, DraftKings may cancel the bets placed on those错误的 odds.
It’s important to check the specific terms and conditions of DraftKings Sportsbook for the most current policies, as they can change, and different states may have different regulations. If you need to inquire about a specific bet, you should contact DraftKings customer service directly for assistance.
