Ares Management (ARES), Amazon (AMZN) and Ken Griffin are set to score large gains from X-Energy's (XE) initial public offering, which is expected to take place Friday at a valuation of over $9 billion, The Wall Street Journal reported, citing people familiar with the matter.

Griffin is poised to register paper gains of about $300 million on a $100 million investment he made about 18 months ago, the people told the media outlet. Ares, which invested over $160 million in X-Energy, is set to make over four times that amount, other people familiar with the matter reportedly said. Amazon owns close to 20% of the nuclear and fuel company, the report said.

Ares, Amazon and Griffin didn't immediately reply to requests for comment from MT Newswires.
