Facebook increasingly wants to be a platform where people buy and sell goods and services, besides connecting with friends. The company over the past year asked JPMorgan Chase JPM 0.37% & Co., Wells Fargo & Co., Citigroup Inc. C 0.01% and U.S. Bancorp USB 0.70% to discuss potential offerings it could host for bank customers on Facebook Messenger, people familiar with the matter said. ...
As part of the proposed deals, Facebook asked banks for information about where their users are shopping with their debit and credit cards outside of purchases they make using Facebook Messenger, the people said. ...
Alphabet Inc.’s Google and Amazon.com Inc. also have asked banks to share data if they join with them, in order to provide basic banking services on applications such as Google Assistant and Alexa, according to people familiar with the conversations.
