PayPal is offering $45 billion to acquire Pinterest. If the deal goes through it could bring financial technologies closer to social media in e-commerce.

This may be the largest acquisition of a social media company, surpassing Microsoft Corp.'s acquisition of LinkedIn. This transaction was about $26.2 billion in 2016, according to sources heard by Reuters.

One of the big social media trends is the ability to buy directly from Instagram or TikTok, for example. Users discover articles on the pages of brands and influencers and immediately purchase those that generate the most interest.

The acquisition of Pinterest would allow PayPal to capture the growing flow of e-shopping through social media, as well as diversify its revenue through advertising revenue.

In any case, a verdict on Paypal's possible purchase of Pinterest should come out on November 8. On that day, Paypal will also present its quarterly results.
