Here’s how much YouTube is worth by Ben Geier @FortuneMagazine May 27, 2015, 12:27 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons An analyst at Bank of America thinks your favorite place for cat videos is worth big money. Analyst Justin Post wrote a note this week saying that YouTube, the popular video streaming site bought by Google in 2006, is worth about $70 billion on its own. That’s a higher value than all but 66 of the companies listed on the S&P 500, according to Bloomberg. Post also thinks that YouTube could still grow, with a valuation of up to $90 billion possible—which would leave only 55 S&P 500 companies beating it. The 2006 deal was for $1.65 billion.
