How X-energy's valuation is determined
Private company valuations aren’t quoted on an exchange — they’re established in moments: a priced funding round sets a post-money valuation, secondary trades print at a price per share, and SEC-registered funds holding the stock report fair-value marks in their N-PORT filings.
For X-energy, we compose those signals into the PA Mark — a weighted composite of 6 recent pricing inputs, decayed by age and reset on new rounds. The implied valuation multiplies the mark by shares outstanding. Full methodology →
