Elon Musk’s SpaceX is already one of the most valuable private companies in the world. Now, it’s set to be worth more than half of Tesla — the electric-vehicle maker he also runs — and is said to be exploring going public.
The rocket maker is planning a secondary share sale that would value it at $800 billion, the Wall Street Journal reported on Friday, citing people familiar with the matter. SpaceX was valued at about $400 billion after its last share sale.
