How are startup shares worth more than the total investment funding?
He is worth $17.5 billion today Note that he is worth that dollar figure, but he doesn't have that many dollars. That's the worth of his stake in the company (number of shares he owns times the assumed value per share), i.e. assuming its total value being several hundreds of billions, as pundits assume. However, it is not a publicly traded company, so we don't really know much about its financials.
