Google, Facebook, Amazon, LinkedIn, Facebook Inc and Twitter are in talks to buy Facebook Inc for $2 billion, the companies said in a joint statement.
The deal will be the first since Google and Facebook announced their $1.5 billion acquisition of WhatsApp in March.
Google is paying $2,062 million in cash, plus $1 billion in share repurchases, the company said in the statement.
Facebook said it will receive $1bn in cash and share repurchase.
The companies said the transaction is expected to close in the second half of 2019, although the timing is subject to regulatory approvals.
Google and Facebook were already discussing their next moves, they added.
The Facebook deal follows the announcement by Facebook CEO Mark Zuckerberg last week that the social network would spend $100 billion to buy the largest Internet company in the world.
Facebook shares have risen more than 14% this year, helped by a push by Zuckerberg to get people to use its platform to send messages.
The social network is valued at $72 billion, according to data provider Morningstar.
Shares of LinkedIn, which are the world’s biggest employer and recruiter network, rose 1.6% to $27.25 on Wednesday.
