The Post has reached out to SpaceX for comment. Johnsen also told workers that SpaceX was a secondary share sale that would set a pre-IPO valuation of $800 billion – entrenching the company as the world’s most valuable privately-held firm and approximately doubling its current valuation. SpaceX is known for its rocket and satellite launches as Musk works with NASA and the federal government to return US astronauts to the moon. The billionaire has said he eventually wants to establish a colony on Mars. The firm also offers Starlink satellite-based internet, which supplies high-speed service to remote areas and has notably seen use by Ukraine’s military during the Russian invasion.
