## Why it is interesting

X-energy is one of the few advanced-nuclear developers with a public stock price and separately documented pre-IPO financings. Its 2026 IPO price, later trading price, revenue-plus-grant disclosures, proposed Amazon-backed power projects and lengthy reactor-delivery milestones should be kept distinct. Alumni Ventures identifies X-energy as a historical portfolio company, but realized AV returns are undisclosed.
