Yes, you can upgrade Venture to Venture X if you’ve had your Capital One Venture account open for at least six months. Give customer service a ring using the number on the back of your card, and they’ll help with the upgrade.  If your credit score and income have improved since you first got the card, your chances of getting the upgrade are even better. And Capital One will sometimes offer you the upgrade without you asking. Unfortunately, upgrading probably means you won’t be eligible for any initial bonuses that come with the Capital One Venture X card (unless they specifically include it in the upgrade offer). But here’s some good news: The Capital One Venture card upgrades don’t require a hard inquiry on your credit report, so it won’t affect your credit score.
