That would be quite a play. Stripe, PayPal, Venmo, Braintree, Xoom all under one umbrella. The Herfindahl-Hirschman Index (HHI) for online card-not-present (CNP) checkout on that is going to be absurdly high and this will take a lot of convincing to beat antitrust. They will probably have to unwind Venmo and Braintree.
