Can You Buy TerraPower Stock? No — But Here's How to Get Exposure
60-second answer: No. TerraPower is a private company founded by Bill Gates, funded by Gates, SK Group, NVIDIA's venture arm, and other private investors, plus US Department of Energy cost-share. There is no TerraPower ticker and no announced IPO. The closest listed exposure runs through its fuel chain: Centrus Energy (LEU) enriches the HALEU its Natrium reactors burn, GE Vernova (GEV) hosts fuel fabrication through Global Nuclear Fuel, ASP Isotopes (ASPI) signed on as a future HALEU supplier, and Uranium Energy Corp (UEC) holds an agreement to explore supplying Wyoming uranium.
You searched for a TerraPower stock price. There isn't one. TerraPower is private, it has stayed private through fifteen years and multiple billion-dollar funding rounds, and nothing public suggests that changes soon.
That answer takes one sentence. The useful part takes the rest of this page: what TerraPower is building, whether an IPO is plausible, and which listed companies genuinely benefit when TerraPower succeeds, ranked by how direct the link really is.
Why TerraPower Has No Stock Price
TerraPower was founded in 2008 by Bill Gates, who remains its chairman and largest backer. Capital has come from Gates himself, South Korea's SK Group, HD Hyundai, NVIDIA's venture arm NVentures, and other private investors, alongside roughly $2 billion in US Department of Energy cost-share for the Natrium demonstration. Private companies with patient billionaire capital and government co-funding face little pressure to tap public markets. So the shares you can buy simply do not exist.
What TerraPower Actually Builds
Natrium is a 345 MWe sodium-cooled fast reactor paired with a molten salt energy storage system that can push output to 500 MWe for over five hours. That storage twist matters: the plant can flex around wind and solar, which no conventional reactor does well.
The first unit is real concrete, not renderings. Construction began at Kemmerer, Wyoming in April 2026 on the site adjacent to a retiring coal plant, with commercial operation targeted around 2030 to 2031. In January 2026, Meta signed on for eight future Natrium plants to power data centers. The order book is the strongest in advanced nuclear. It just isn't one you can buy directly.
Will TerraPower IPO?
No filing exists, and the company has said nothing firm. The honest read: an IPO becomes plausible once Kemmerer approaches completion and the Meta-scale orders need serial production capital. That points years out, not quarters. Treat any "TerraPower IPO date" content you find elsewhere as guesswork.
Six Listed Ways to Get TerraPower Exposure
1. Centrus Energy (NYSE: LEU). The most direct link. Natrium burns HALEU, uranium enriched to just under 20%, and Centrus operates the only NRC-licensed HALEU cascade in the United States at Piketon, Ohio. TerraPower and Centrus signed agreements to scale commercial HALEU production, and in January 2026 the DOE awarded Centrus a $900 million task order to expand capacity. If Natrium plants multiply, someone enriches every core. Full breakdown in our enrichment stocks guide.
2. GE Vernova (NYSE: GEV). Natrium fuel will be fabricated at the Natrium Fuel Facility on the Global Nuclear Fuel Americas site in Wilmington, North Carolina. GEV is a giant, so this is diluted exposure, but it collects on TerraPower's success and runs its own BWRX-300 SMR program besides.
3. Uranium Energy Corp (NYSE: UEC). TerraPower and UEC hold an agreement to explore Wyoming-mined uranium as Natrium feedstock. Early stage and non-binding, but it is the only listed miner with a named TerraPower connection.
4. ASP Isotopes (NASDAQ: ASPI). TerraPower signed a term sheet to invest in ASP's planned HALEU enrichment facility in South Africa and purchase its output. Small company, binary outcomes, real contractual link.
5. Berkshire Hathaway? The proxy that doesn't work. A persistent piece of internet folklore says Berkshire gives you TerraPower exposure. It doesn't. The confusion comes from geography: Kemmerer sits beside a coal plant owned by PacifiCorp, a Berkshire utility, and PacifiCorp has studied hosting future Natrium units. Berkshire owns no stake in TerraPower, and a first-of-a-kind reactor rounds to zero inside a trillion-dollar conglomerate. Skip it.
6. The fuel-side basket. The most robust logic of all: you do not need to know whether TerraPower, Oklo, or NuScale wins. Every advanced reactor buys uranium and enrichment. A basket across miners, Centrus, and physical uranium vehicles gets paid by the whole race, not one horse.
The Risk Section Nobody Writes
Proxy investing has a failure mode: the proxy carries its own risks that dwarf the TerraPower link. Centrus still depends on government contracting cadence. ASPI is a micro cap building first-of-a-kind plants. UEC's TerraPower agreement is exploratory. Size positions on each company's own fundamentals, with the TerraPower connection as upside, not thesis.
FAQ
Is TerraPower publicly traded? No. It is a private Delaware company. Any site quoting a "TerraPower share price" is showing you a different security or private secondary-market estimates you cannot act on.
Who owns TerraPower? Bill Gates (founder and chairman) plus private investors including SK Group, HD Hyundai, and NVentures, with DOE cost-share funding the Natrium demo.
Can I buy pre-IPO TerraPower shares? Accredited investors sometimes find secondary platforms listing private nuclear names. Availability, pricing, and legitimacy vary wildly, and this site does not cover or endorse that route.
Next Step
The pattern here repeats across nuclear: the most exciting builders are private, and the listed money is in their supply chains. See the sibling explainers on Westinghouse and fusion companies, then follow the fuel through the reactor tracker.
