SpaceX, the space transportation and satellite making company run by Elon Musk, is preparing to sell its insider shares in a transaction that would value it at higher than $500 billion, Bloomberg reported quoting people familiar with the development. This means that SpaceX is on its way to break OpenAI's record, which had sold its shares to have a $500 billion valuation — a first in history. According to the people quoted by Bloomberg, the insider share selling could increase the valuation of SpaceX to about $800 billion.
