Goldman Sachs Said to Invest $450 Million in Facebook

Facebook Inc. received a $500 million investment from Goldman Sachs Group Inc. and Russia’s Digital Sky Technologies that values the social-networking company at $50 billion, according to three people familiar with the matter.

Goldman Sachs, which invested $450 million, also made an arrangement that lets its clients buy Facebook equity worth as much as $1.5 billion, said two of the people, who asked not to be identified because the deal is private. Digital Sky invested $50 million, boosting an earlier stake, the people said.
