No, Capital One Venture miles do not expire for the life of the account. As of March 2026, Capital One maintains a very consumer-friendly policy: as long as your account remains open and in good standing, your miles are yours to keep. However, you will lose all your miles immediately if you close the account without first redeeming them or transferring them to another active Capital One rewards card. If you are planning to close a Venture card but want to save your points, a popular 2026 strategy is to "downgrade" to a no-annual-fee card like the VentureOne, which allows you to preserve your balance indefinitely. You can also transfer your miles to one of Capital One’s 15+ travel partners (like British Airways or Choice Privileges) before closing the account to ensure the value isn't lost. Note that "misuse" of the account—such as fraudulent activity or failing to make payments for several months—can also lead to an involuntary account closure and the subsequent forfeiture of all accumulated rewards.
