What a lot of people don't realize is that Musk is way undervalued at a net worth at $350B. If and when he takes SpaceX public, he has the potential to go to One Trillion.
To put it in perspective, right now Musk's networth is greater than the GDP of 151 of the 190 countries of the world.
SpaceX is one of the few companies I would add postion to, if I could.
