Elon Musk has said says he wants to take Tesla private. The electric car company’s chief executive announced he was considering as much with an impulsive tweet Aug. 7, and expanded on his thinking in a letter to employees, a blog post and an interview. What is not clear is how, exactly, Musk would pull off such a deal. Tesla is publicly traded on Nasdaq and has a market value of about $55 billion. Were Musk to take Tesla private at his proposed price of $420 a share, Tesla would be valued at about $71.6 billion.
