When Will TerraPower Go Public? IPO Outlook and Alternatives
No, TerraPower is not publicly traded. Retail investors can’t buy TerraPower stock directly today, so the realistic paths are waiting for an IPO, using accredited-only private secondary markets, or looking at public nuclear peers like OKLO, SMR, and LEU.

TerraPower is getting more attention because it sits at the intersection of advanced nuclear power, AI-era electricity demand, and industrial decarbonization. The company has also been busy: it raised $650 million in June 2025, added strategic investors, and later announced a deal with Meta to develop up to 8 Natrium plants in the U.S.
That kind of momentum is exactly why retail investors keep searching for TerraPower stock. The catch is simple: there is no public listing to buy today. Here’s what TerraPower does, whether it’s public, what an IPO would require, and the closest ways investors can get exposure now.
What is TerraPower?
TerraPower is a nuclear innovation company founded in 2006 and headquartered in Bellevue, Washington. Its flagship program is Natrium®, an advanced reactor paired with energy storage that TerraPower says is designed to deliver carbon-free electricity and support industrial decarbonization. The company also has an isotopes business focused on radioisotopes for cancer treatment.
This is a private, founder-backed company rather than a utility. Bill Gates is chairman, Nathan Myhrvold is vice chairman, and TerraPower says it was founded by Gates and a group of visionaries. TerraPower does not disclose revenue on its website, and a primary-source employee count was not found. The company’s customer and partner base includes names like Meta, SK, KHNP, and Centrus Energy, which matters because TerraPower’s commercialization depends on both reactor deployment and fuel supply.
Is TerraPower publicly traded?
No, TerraPower is currently a privately held company and does not trade on NYSE or NASDAQ. TerraPower’s own site identifies it as TerraPower, LLC, with headquarters in Bellevue, Washington.
Because it is private, there is no public float, no retail brokerage ticker, and no ordinary way for most investors to buy shares directly. Ownership is not fully disclosed, but the company is clearly founder-influenced and backed by strategic investors rather than public shareholders.
When will TerraPower go public?
There is no S-1 filing for TerraPower on SEC EDGAR, and I found no public statement from the company saying it plans to go public. I also didn’t find credible banking or analyst chatter in the reviewed sources suggesting an IPO is imminent. The company’s recent activity looks like a private company still raising capital and signing strategic partnerships.
The most recent disclosed valuation I found was a $400 million estimate from September 2024, but that appears to be a database estimate rather than a company-announced valuation. TerraPower’s June 18, 2025 fundraise brought in $650 million, but the company did not disclose a valuation. If TerraPower ever files to list, investors should watch for an S-1, underwriter announcements, and a clearer path to commercial deployment.

For retail investors, the first option is to wait for an IPO. If TerraPower ever goes public, you’d typically participate the same way you would with any new listing: through a brokerage account once shares begin trading, or through an IPO allocation if your broker offers access. Right now, that path is hypothetical.
The second option only applies if TerraPower had a public parent, which it does not. So there is no parent ticker to buy here. The third option is what most retail investors end up doing: buy publicly traded companies that are closest to TerraPower’s business, especially advanced nuclear names like OKLO, SMR, and LEU.
A fourth route exists for accredited investors only: private secondary markets. TerraPower is listed on private-market platforms such as Forge Global and Hiive, but access is limited, pricing can be opaque, and these venues are not open to most retail investors. That makes them a niche option, not a mainstream workaround.
Closest publicly-traded alternatives
The closest public proxy is Oklo (NYSE: OKLO). It’s another advanced nuclear developer, so investors looking for TerraPower exposure often start there because both are trying to commercialize next-generation reactor technology.
NuScale Power (NYSE: SMR) is another relevant comp. It’s also an advanced nuclear technology company, though its reactor approach differs from TerraPower’s Natrium program. Centrus Energy (NYSE American: LEU) is the third key comp because it is not a reactor developer, but it is central to advanced nuclear fuel supply, and TerraPower has a supply agreement with Centrus for HALEU. These are the public names investors usually compare against TerraPower when they want a tradable nuclear-tech basket instead of a private-company stake.
Recent news
TerraPower’s biggest recent move was its June 18, 2025 fundraise, which brought in $650 million and included Nvidia’s NVentures alongside existing backers such as Bill Gates and HD Hyundai. That was followed by more strategic momentum in 2026, including a January 9 agreement with Meta to develop up to 8 Natrium plants in the U.S.
The company also said KHNP joined its investor base on January 20, 2026, and on March 4, 2026, TerraPower said the NRC voted to award the first Natrium plant, Kemmerer Unit 1, a construction permit. Those are the kinds of milestones investors watch because they move TerraPower from concept toward deployment.
Verdict
If you want TerraPower specifically, the honest answer is that you can’t buy it like a normal stock today. It’s private, there’s no IPO filing, and there’s no clear public timetable.
For most retail investors, the practical move is to watch for an eventual listing while using public proxies in the meantime. OKLO, SMR, and LEU are the closest tradable names investors look at when they want exposure to the same advanced nuclear theme.
