Unlike some reward card siblings, we’ve heard from Capital One that if you’re a current Venture cardholder that you can apply for the Venture X and hold both at the same time. We haven’t heard whether eligible Venture cardholders will also be able to qualify for the Venture X sign-up bonus, but keep in mind that Capital One limits applying cardholders to one new card every six months and you can only hold two personal Capital One cards at once. So if you already have one of the issuer’s cash back cards, it’s likely worth letting go of the Venture since the Venture X would make it redundant anyway.
