Dec 5 (Reuters) – SpaceX is kicking off a secondary share sale that would value the rocket-maker at $800 billion, the Wall Street Journal reported on Friday, citing people familiar with the matter.

SpaceX’s finance chief, Bret Johnsen, told investors about the sale in recent days, the report said. The $800 billion valuation is double the $400 billion value it fetched in a recent secondary share sale.

The company, founded by Elon Musk, did not immediately respond to a Reuters request for comment.
