This probably comes as little surprise, but co-founder and CEO Elon Musk is the largest shareholder in Tesla. His holdings are even greater than those of the largest financial institution.

If he can manage to achieve his ambitious goals for the company, and build its market capitalization to $551 billion over the next ten years, that pile of paper will only grow. The board approved a compensation package that will award him 12 tranches of stock options equal to  1 percent of outstanding shares if he can hit the required high notes.

As of August 7, 2018, Musk had an estimated net worth of $21.2 billion.
