TerraPower Stock Price: Private Valuation and Investment Guide

Investors tracking the terrapower stock price often find themselves at a crossroads between traditional equity markets and the exclusive world of private venture capital. TerraPower LLC, a leading nuclear innovation firm founded by Bill Gates in 2006, represents a frontier in carbon-free energy through its Natrium™ reactor technology. However, because it remains a privately held entity, there is no ticker symbol on the NASDAQ or NYSE, and no daily public stock price to monitor.

1. Company Profile: The Vision of Bill Gates

TerraPower is not a typical energy utility; it is a nuclear technology incubator. Headquartered in Bellevue, Washington, the company focuses on Small Modular Reactors (SMRs) and travel-wave reactor designs. Its flagship project, the Natrium plant in Wyoming, aims to revolutionize the power grid by integrating sodium-cooled fast reactors with molten salt energy storage. As of late 2024 and early 2025, the company has transitioned from theoretical design to active construction, significantly impacting its perceived market value.

2. Stock Availability and Public Status

2.1 Private Company Status

Currently, there is no official terrapower stock price available on public brokerage apps. The company has not filed for an Initial Public Offering (IPO). For retail investors, this means shares cannot be purchased through standard accounts at this time. The lack of a public ticker allows the company to focus on long-term R&D without the pressure of quarterly earnings reports.

2.2 Pre-IPO Trading Platforms

While not public, "pre-IPO" shares are occasionally traded on secondary marketplaces. On platforms such as Hiive, Forge Global, and EquityZen, the terrapower stock price (often identified under the internal symbol TEPO) reflects private transactions between employees or early investors and accredited buyers. According to data from secondary markets in late 2025, estimated prices for these private shares have fluctuated between $86.13 and $88.28 per share, though these figures are subject to low liquidity and high volatility.

3. Estimated Valuation and Funding History

3.1 Total Capital Raised

TerraPower’s valuation is driven by its massive capital raises. According to reports from CB Insights, the company has raised over $1.6 billion to date. A pivotal moment occurred in mid-2025 when the company secured an additional $650 million in funding to accelerate the Natrium project, further boosting its private valuation into the multi-billion dollar range.

3.2 Key Investors

The company's financial backing is a "who's who" of institutional and private wealth. Major investors include:

• Bill Gates: The primary founder and largest individual backer.
• SK Inc. and HD Hyundai: Major South Korean industrial conglomerates focusing on green energy.
• NVentures: The venture capital arm of Nvidia, highlighting the intersection of AI-driven energy needs and nuclear power.

4. Investment Requirements

4.1 Accredited Investor Criteria

To participate in secondary market trading and access the terrapower stock price directly, U.S. investors generally must meet "accredited investor" status. This typically requires an annual income exceeding $200,000 ($300,000 for couples) or a net worth exceeding $1 million, excluding a primary residence.

4.2 Indirect Investment Options

For those who do not meet accreditation standards, indirect exposure is the only path. This includes investing in TerraPower’s partners, such as Southern Company, or looking into ETFs that focus on uranium and nuclear technology. While this doesn't provide a direct link to the terrapower stock price, it allows investors to benefit from the broader growth of the SMR sector.

5. IPO Outlook and Future Milestones

5.1 The 2030 Roadmap

Industry analysts, including those from The Motley Fool, suggest that a TerraPower IPO is unlikely before the first Natrium reactor becomes operational. The current construction timeline in Kemmerer, Wyoming, targets 2030 as a key operational milestone. Successful energy generation at scale would serve as the ultimate catalyst for a public listing.

5.2 Regulatory and Technological Risks

The valuation remains sensitive to Nuclear Regulatory Commission (NRC) approvals and the supply of High-Assay Low-Enriched Uranium (HALEU). Any delays in the fuel supply chain or regulatory hurdles could downwardly pressure the private terrapower stock price before it ever hits the public market.

6. Publicly Traded Alternatives

If you are looking for immediate liquidity in the nuclear space, several competitors are already public:

• NuScale Power (SMR): The first company to receive NRC design approval for an SMR.
• Oklo Inc. (OKLO): A Sam Altman-backed company focusing on fast fission reactors.
• Cameco (CCJ): A major uranium producer essential for the fuel cycle.

As the energy landscape shifts toward sustainable solutions, keeping an eye on private giants like TerraPower is essential.
