DraftKings’ ability to provide instant payout withdrawals is at the discretion of both the card brand (Visa, Mastercard, American Express, or Discover) and payment issuer (your financial institution).
If you aren’t able to use your card on file for this withdrawal type, it may be because your card brand or payment issuer hasn’t approved instant payout withdrawals for DraftKings.
All cards saved on your account will be listed, however, any grayed out card hasn’t been approved for instant payout withdrawal by either the card brand or payment issuer.
