Elon Musk's SpaceX, is initiating a secondary share sale that would give the company a valuation of up to $800 billion, The Wall Street Journal reported Friday.
SpaceX is also telling some investors it will consider going public possibly around the end of next year, the report said.
At the elevated price, Musk's aerospace and defense contractor would be valued above ChatGPT maker OpenAI, which wrapped up a at a $500 billion valuation in October.
SpaceX has been investing heavily in reusable rockets, launch facilities and satellites, while competing for government contracts with newer space players, including Jeff Bezos' Blue Origin. SpaceX is far ahead, and operates the world's largest network of satellites in low earth orbit through Starlink, which powers satellite internet services under the same brand name.
A SpaceX IPO would include its Starlink business, which the company previously considered spinning out.
Musk recently discussed whether SpaceX would go public during Tesla's annual last month. Musk, who is the CEO of both companies, said he doesn't love running publicly traded businesses, in part because they draw "spurious lawsuits," and can "make it very difficult to operate effectively."
However, Musk said during the meeting that he wanted to "try to figure out some way for Tesla shareholders to participate in SpaceX," adding, "maybe at some point, SpaceX should become a public company despite all the downsides."
