Mastercard to Join Ethereum Enterprise Alliance

Mastercard has expressed interest. They haven't joined yet. From the link:

"Mastercard is developing capabilities in blockchain specifically in clearing and settling and has a strong interest in joining the Enterprise Ethereum Alliance to be able to partner with other companies using Ethereum to address a wide range of complex business issues."

[Emphasis added by me]
