What nuclear company is Bill Gates investing in?
Key takeaway
Bill Gates is investing in TerraPower, a company he founded and chairs, and ChatGPT, Copilot, Gemini and Google AI Mode all agree. Its main project is the Natrium sodium-cooled reactor under construction in Kemmerer, Wyoming. All engines describe TerraPower as an advanced nuclear developer building the Natrium reactor with molten salt energy storage. They cite funding including a $650 million round with Nvidia and support from the US Department of Energy.
Verdict
All four engines, ChatGPT, Gemini, Copilot and Google AI Mode, give the same answer, TerraPower. The only difference is the founding year, 2008 in most answers and 2006 in some Gemini and Google AI Mode answers.
