Backed by Silicon Valley capital and national security insiders, companies like General Matter are reviving the nuclear sector as part of a broader push to restore America's industrial might read more
In the changing world of American tech ambitions, a new group of venture capitalists is shifting focus. Instead of just investing in digital technologies (known as 'bits'), they are now turning to real, physical industries (called 'atoms'). One clear example of this shift is a company called General Matter.
This startup is working in nuclear enrichment and is trying to change how America powers itself and protects its national security. According to an article in The Economist from April 20, 2025, General Matter is not only challenging old nuclear companies but is also becoming a key part of what could be America's next big industrial movement.

A new age of private nuclear enterprise
General Matter has a bold goal. It wants to be the first private company in the US to produce a special kind of nuclear fuel called Haleu (high-assay, low-enriched uranium). This fuel is very important for the next generation of nuclear reactors. Unlike older models, the new generation of nuclear reactors is compact, simpler to construct and designed to operate more efficiently.
Instead of using fuel enriched to just 5 per cent like conventional reactors, these advanced systems require uranium enriched up to 20 per cent. According to The Economist, the US Department of Energy asked General Matter to join its Haleu consortium back in 2023 — even before the company was officially created. This shows how important the government thinks the company is and it also hints at the strong political connections it has.
The company was started by Scott Nolan, who used to work at SpaceX and is now a venture capitalist, and Lee Robinson, who used to work in intelligence. Together, they represent a mix of Silicon Valley smarts and national security know-how.
They're backed by the Founders Fund, led by Peter Thiel, which has supported big, bold tech ideas for years, and is a strong Trump-backer. But General Matter shows something new — it's a hands-on move into critical industries that affect both energy and defence in America.
Political proximity and strategic intent
The success of General Matter isn't happening in isolation. It's closely connected to the growing political and ideological support for nuclear energy during the Trump administration. In February 2025, The National Interest magazine reported that people like Preston Wells Griffith III, who worked on Trump's National Security Council, and Brandon Williams, a nuclear entrepreneur who now advises the Department of Energy, have played a big role in pushing policies that focus on American-made energy technologies.
Under their leadership, the Department of Energy has shifted its funding and rules to speed up the development of the domestic Haleu supply chain.
Thiel's group of investors and political supporters has seized this moment to position nuclear enrichment as not just an industrial chance, but as a national mission. Trae Stephens from Founders Fund told The Economist that the goal is to make sure America doesn't fall behind authoritarian countries in the nuclear race.
A return to Cold War roots
The support behind General Matter represents a return to a history that Silicon Valley has often tried to move away from. As historian Margaret O'Mara explained to The Economist the early tech companies in the Bay Area grew out of Cold War defence contracts, many of which were related to atomic weapons and missile systems.
Over time, Silicon Valley moved away from military projects and adopted a more libertarian mindset. But now, with companies like General Matter and Anduril — another defence startup backed by Thiel — there's a new focus on working with the government, but this time to promote technological nationalism.
O'Mara described this shift as 'a Space Age, brought to you by Ayn Rand,' which refers to the contradiction in Thiel's approach. The philosophy may be libertarian, but the work relies heavily on government support — like DOE grants, national security exemptions and faster rules for getting things done. Even so, The Economist noted that these new industrialists don't see a problem with this. They think the government isn't an obstacle but a vital partner in helping America reclaim its industrial power.

Is energy security venture capital's next frontier?
General Matter's rise fits into a bigger plan that Thiel and his supporters are working on. As Stephens told The Economist, their investment strategy has evolved over time: Palantir changed intelligence operations, Anduril is changing defence and now General Matter aims to do the same for nuclear energy. E
ach of these companies is about using private money and advanced technology to reshape important areas of the government.
The push for this is driven by the belief that the US is too dependent on foreign suppliers for important infrastructure. Right now, Russia provides about 35 per cent of the enriched uranium used in American reactors.
This has become a bigger problem since the war in Ukraine. General Matter makes it clear that every part of its business is designed and funded in the US. The company positions itself as a patriotic choice compared to the foreign-controlled uranium supply chain, as mentioned in The Economist article.
Bureaucratic realities and technical hurdles
However, turning this vision into reality won't be easy. General Matter has not yet applied for a Nuclear Regulatory Commission (NRC) license, which is required before any uranium enrichment can begin. Getting this license takes time and the regulations are strict—especially for something as politically and environmentally sensitive as uranium enrichment.
While General Matter talks about new centrifuge designs that promise more efficiency, it still has to compete with companies that already have the infrastructure in place.
For example, Centrus Energy began producing small amounts of Haleu in 2023, the first in the US in seven decades, as The Economist pointed out. On top of that, General Matter faces another challenge: small modular reactors, which need Haleu, are still mostly in the development stage. There isn't much demand for enriched fuel until these reactors get broader commercial approval.

Tariffs and trade-offs
Even though the Trump administration strongly supports nuclear energy, some of its other economic policies might hurt the industry's ability to compete. A February 2025 analysis in The National Interest warned that tariffs on materials like steel, aluminium and other industrial goods could make it more expensive to build nuclear reactors. These tariffs are meant to protect American manufacturing, but they might also make US nuclear projects too costly — both inside the country and overseas.
This problem gets worse because of rising tensions with allied countries. Trade disputes with Canada and European partners could make it harder to work together on important projects and supply deals that the Haleu fuel chain depends on. The Council on Foreign Relations has warned that if the US doesn't create a clear international plan, it could end up isolated—just when it's trying to lead the world in nuclear energy again.
Nuclear weapons versus Trump's pragmatism
Interestingly, while the Trump administration sees nuclear energy as a key part of national strength, it has taken a more cautious approach to nuclear weapons. In February 2025, President Trump questioned the need to expand the US nuclear weapons arsenal.
Trump said the current stockpile is already enough to protect the country. He also criticised the $1.7 trillion plan to modernise the arsenal that started under earlier presidents and said he was open to new arms control talks with Russia and China.
This change in attitude was explained by Lucas Ruiz and Geoff Wilson in the Bulletin of the Atomic Scientists. They pointed out that there is a split between some Republicans who want to upgrade weapons and a president who sees more value in peaceful, nonmilitary nuclear technology.

For Trump, building up the country's civilian nuclear power might be a stronger symbol of America's comeback than showing off military force.
The atomic gamble
General Matter's story represents a bigger change happening in US. It's a test to see if private companies — working with government support — can bring back an industry that many thought was outdated. It's also a test to see if the future of American technology will be built not just in app stores and cloud servers, but through nuclear tools like centrifuges, control rods and containment systems.
General Matter is supported by investors with strong beliefs, backed by powerful political supporters and lifted by a growing sense of techno-patriotism—a belief that technology can help rebuild national pride.
The company is betting everything on the idea that America's next big achievement will come from nuclear energy. But whether this gamble works won't just depend on technology or money — it will also depend on how well they deal with global politics, government rules and public opinion.
If they succeed, what some are calling the 'Manhattan Beach Project' could become the most important industrial story of the 2020s.
