About TerraPower
TerraPower is a nuclear power company creating a smarter, safer, and more efficient way to generate power to reduce carbon emissions in the 21st century.
The company was founded by Bill Gates and “like-minded” investors. It aims to fully scale its nuclear reactor design by the end of the decade.
As the world population grows and the global economy shifts toward electric vehicles, renewable fuels such as solar and wind will not be enough to support clean energy demand.
Modernized nuclear power and possibly fusion technology from the likes of Helion Energy and Tae Technologies are innovative solutions to power the planet more cleanly and efficiently.
TerraPower’s design uses less radioactive fuel and reduces safety risks and waste. It uses molten sodium to store energy, giving it the flexibility to release energy when demand increases.
This webinar gives an excellent overview of the technology.
The company is in the early stages of prototyping and building its 345-megawatt sodium-cooled Natrium power plant in Wyoming and plans to build a second facility in Idaho. The U.S. government will fund about half of the $4 billion Wyoming project.
The video below explains more about the case for nuclear power.
Ownership
TerraPower shareholders include Bill Gates, the billionaire founder of Microsoft, and venture capital investors including Intellectual Ventures, SK Group, HD Hyundai, ArcelorMittal, NVentures (Nvidia), and CRV.
It also raises funds for operations through federal grants.
IPO Potential
The TerraPower IPO date is currently unknown. The company is likely several years away from an IPO.
Building nuclear power plants is capital-intensive and takes many years due to safety and environmental concerns. The designs are highly complex.
Therefore, TerraPower is likely at least five years away from generating any power or revenue.
We won’t get a better sense of the TerraPower IPO date until we learn about its progress in verifying its prototypes.
These other events down the line can also give us clues as to when the IPO is nearing:
- The company announces another funding round
- New information about the TerraPower IPO date leaks to the financial press
- TerraPower announces (or leaks) that it filed an S-1 confidentially with the SEC
- The SEC releases a publicly available TerraPower S-1 filing
- Announcement (or press leak) of a forthcoming SPAC merger
- TerraPower selects a lead underwriter or banking partner for the IPO
These milestones and announcements will serve as supporting evidence of progress toward a forthcoming public offering. But again, the author doesn’t expect an IPO for at least five years.

How to Buy TerraPower Stock in the Future
Generally, it’s challenging to acquire shares of high-demand pre-IPO companies. Most investors will need to settle for buying the stock after it begins trading.
IPO underwriters typically give their best customers access first, then allocate shares to certain institutions and brokers often tied by existing relationships.
When the largest brokers receive IPO shares, they divvy them up amongst their eligible customers, prioritizing their most valued customers first (wealthiest).
For high-demand deals, most investors will not get shares.
Here are three potential ways to own TerraPower stock when the company is closer to becoming publicly traded.
1. Attempt to acquire TerraPower Pre-IPO
Over the past decade, a handful of pre-IPO investing platforms have emerged to provide liquidity to early equity owners (e.g., employees).
Prominent marketplaces in the space include Hiive, EquityZen, Forge Global, and Linqto.
Shares also become available when employees or other early investors want to liquidate a portion of their shares without waiting for the IPO.
To be eligible to buy pre-IPO shares, investors must first be accredited, meaning a net worth above $1 million (not including primary residence) or an income above $200,000 (or $300,000 with a spouse).
Investors must also be registered and approved on pre-IPO investing platforms to receive notifications when shares become available.
Non-accredited retail investors can gain exposure to startup equity via pre-IPO venture capital funds like the Fundrise Innovation Fund (review).
However, you cannot select individual pre-IPO companies, and TerraPower stock is not in the portfolio at this time.
The author has seen no evidence of pre-IPO access to TerraPower since its founding.

2. Buy the stock during the TerraPower IPO
Interested investors may find opportunities to invest during the IPO. That means acquiring shares at the IPO price the night before the company begins trading.
However, the IPO is likely several years away.
Once reserved for Wall Street’s wealthiest customers, IPO access has become more attainable to retail investors in the past five years.
Online brokers such as the following give customers free access to IPOs, even with low account balances.
TradeStation has a longer track record of accessing more than 360 IPOs and secondary offerings via its partnership with ClickIPO.
Robinhood has the advantage of Silicon Valley networks and a history of getting allocations for high-profile IPOs.
Check out this list of best brokers for IPO investing to learn more about IPO access for retail investors.
3. Buy TerraPower stock after it begins trading
Most investors will not be able to own TerraPower stock until after the IPO. We have no idea when the IPO will occur at this early stage.
It’s likely years away.
The Wyoming powerplant is not expected to begin operating until 2030, presumably marking the onset of significant revenue generations.
With the deep-pocketed and purpose-driven Bill Gates being a primary investor, TerraPower does not need individual investors’ dollars. Venture capital and private investors will be eager to invest before an IPO.
Unfortunately, investors will struggle to become investors soon unless TerraPower becomes available on a pre-IPO platform. Even then, shares will be limited.
By the time the IPO arrives, the private valuation will be fair and several billion dollars higher than where it is today. At the IPO, it will become a typical utility stock (slow growth, reliable cash flow) and probably not a fast-growing company.
Frequently Asked Questions (FAQs)
Is TerraPower Stock Publicly Traded?
No. TerraPower is not publicly traded. It is a private company.
What is the TerraPower Stock Price?
Since TerraPower is not publicly traded on a stock exchange, there is no TerraPower stock price yet.
Private stock price information is becoming more available and reliable based on pre-IPO marketplace data and other sources.
However, TerraPower is not an active private stock on pre-IPO exchanges. Investors like Bill Gates have a very long-term outlook on the company and are not interested in liquidating shares.
What is the TerraPower Stock Symbol?
TerraPower has not yet submitted public filings to the SEC. Therefore, we don’t know what the TerraPower stock symbol will be or if it will ever go public at all.
But we can speculate. Here are a few stock symbol suggestions available in the U.S.
- TP
- TPWR
Can you Invest in TerraPower Stock Today?
No. We’ve seen no evidence of pre-IPO marketplace activity for TerraPower stock. That could change if the company raises a private funding round and equity-holding employees want to cash out.
Where is the TerraPower S-1 Filing?
The TerraPower S-1 filing is not yet available. Once it is public, we’ll post it here.
Startups often file their S-1s confidentially a few months before the public release. News of a confidential filing will help determine the TerraPower IPO date.
You can find a real-time SEC feed of the latest IPO filings from companies on the recent S-1 filings page.
