About General Matter
General Matter is a U.S. uranium enrichment startup aiming to produce high-assay low-enriched uranium (HALEU) and low-enriched uranium (LEU) for advanced nuclear reactors.
Founded in 2024 by former SpaceX engineer Scott Nolan and energy-defense veteran Lee Robinson, the company was incubated at Peter Thiel’s Founders Fund and unveiled in April 2025.
Its core business is enriching uranium hexafluoride into LEU and especially HALEU, addressing a domestic supply gap and growing demand from small modular reactors.
General Matter focuses solely on enrichment, not mining, conversion, or fuel fabrication. Headquartered in San Francisco, it plans its first major facility in Paducah, Kentucky, repurposing a former gaseous diffusion plant site.
Competitors include Urenco USA, Orano USA, and Centrus Energy, but General Matter stands out as the first privately funded U.S. firm building a full HALEU enrichment plant with scalable, lower-cost technology.
Backed by DOE support, a $1.5B Paducah investment, and ongoing regulatory approval, it targets commercial operations by decade’s end, positioning itself to strengthen U.S. energy security and nuclear supply chains.
Here’s an interview with CEO Scott Nolan on the Shawn Ryan Show.
Ownership
General Matter is a venture-backed private company. Investors include the founders, employees, and two prominent venture capital firms: Founders Fund and IQT.
General Matter has raised at least $50 million and has signed a lease to repurpose an existing Kentucky plant with a $1.5 billion investment.
The startup will likely raise a new round of private funds from a more diverse investor base to secure the necessary investment capital for repurposing the plant, in addition to securing government funding.
Valuation
A General Matter valuation is not yet publicly known.
IPO Potential
The General Matter IPO date is currently unknown and unlikely in the next several years.
How to Invest in General Matter Stock
Retail investors will struggle to find investment opportunities in General Matter at this stage of growth.
Its valuation is unknown, and the first broadly accessible investment round has not taken place yet.
Accredited investors can monitor pre-IPO platforms for direct investment opportunities as more shares become available as the company grows.
General Matter is an early-stage startup with a small number of current investors. Scarcity makes investment opportunities unlikely to come by until it raises more funds.
As the company grows, investors can monitor pre-IPO investing platforms such as Hiive, Augment, EquityZen, Nasdaq Private Markets, and Forge Global for share availability.
These platforms enable employees and early shareholders to sell their shares when there is limited liquidity in other markets.
Accredited retail investors may also have the opportunity to invest, often at lower valuations.
Investment minimums typically range from $10,000 to $50,000 or more on these platforms, though the availability of a company of this size will be limited.
Investors can register for free access to pre-IPO data, receive alerts, and monitor the availability of startup shares.
Another way to invest in pre-IPO companies is via the Fundrise Innovation Fund.
Ordinary investors can own startups like Databricks, Canva, Anthropic, Anduril, and others through the Fund. General Matter is not part of the portfolio at this time.

Conclusion
General Matter represents a rare venture-backed push into a sector long dominated by government contracts and legacy players.
Its decision to anchor operations in Paducah, KY, revives a site once central to U.S. nuclear capacity, signaling both continuity and renewal for domestic enrichment.
While the startup remains months, if not years, away from revenue, the early involvement of the DOE and a $1.5 billion facility plan provide credibility beyond a typical pre-IPO narrative.
For investors, scarcity is both the obstacle and the attraction: few shares will change hands before larger rounds, but those who gain exposure may benefit from a structural supply gap in HALEU.
The company’s trajectory will depend not only on technology execution but also on navigating a complex regulatory environment that can slow or accelerate its timeline.
Competitors with entrenched infrastructure will not stand still, yet General Matter’s private funding model and singular focus on enrichment give it a distinct angle.
Interested investors must be patient for new funding rounds complete, potentially opening opportunities to invest in General Matter stock.
