What was the approximate purchase price Yahoo paid for Tumblr in 2013?

Yahoo paid approximately $1.1 billion to purchase Tumblr in 2013. Yahoo announced the all-cash deal on May 20, 2013, and the acquisition was completed on June 20, with Tumblr founder David Karp remaining as chief executive.

The purchase was one of Yahoo CEO Marissa Mayer's most prominent acquisitions. Yahoo hoped Tumblr's large, highly engaged audience would help it compete with newer social-media companies and attract younger users. At the time, Tumblr was a rapidly growing blogging and social-networking service, even though it had not established a strong revenue model.

The deal is often remembered because its eventual results contrasted sharply with the original price. Yahoo later wrote down much of Tumblr's value, and Verizon Media sold Tumblr to Automattic in 2019 for a reported amount far below Yahoo's purchase price. The $1.1 billion figure refers to the announced acquisition value, substantially paid in cash, rather than Tumblr's later resale value.
