General Matter, a startup based in Los Angeles, has raised US$50 million in funding to produce high-assay low-enriched uranium (HALEU) for advanced nuclear reactors.

The funding round was led by venture capital firm Founders Fund, with partner Peter Thiel joining the board.

Co-founded by Scott Nolan, a former SpaceX engineer and Founders Fund investor, and Lee Robinson, a former Defense Department energy specialist, the company aims to enrich uranium to 19.75%.

General Matter has assembled a team of approximately two dozen engineers, nuclear scientists, and safety experts, pulling talent from national labs and the private sector.

🧠 Food for thought

1️⃣ The critical national security dimension of domestic HALEU production

General Matter’s entry into HALEU production addresses a significant vulnerability in the U.S. nuclear supply chain that has drawn substantial government attention.

The Department of Energy recently awarded contracts worth up to $2.7 billion for HALEU enrichment services to four companies, including General Matter, highlighting the strategic importance of domestic production capacity1.

This initiative comes as the U.S. works to reduce dependence on foreign HALEU supplies, particularly from Russia, which has historically been the primary global source.

Just last week, the DOE issued conditional commitments to supply HALEU to five U.S. nuclear developers (TRISO-X, Kairos Power, Radiant Industries, Westinghouse Electric, and TerraPower) to support their immediate fuel needs for advanced reactor deployment2.

The timing of General Matter’s funding coincides with the DOE’s goal to distribute 21 metric tons of HALEU by June 2026, establishing a secure domestic supply chain for this critical material3.

2️⃣ Venture capital making strategic bets amid a nuclear renaissance

General Matter’s $50 million funding round signals growing private investor confidence in nuclear energy at a time when global interest in the sector is surging.

The nuclear energy sector is projected to experience significant growth, with global nuclear power generation increasing by nearly 3% annually through 2026, and an additional 29 GW of nuclear capacity expected to come online worldwide in the coming years4.

This investment comes as many countries are reassessing nuclear power’s role in their energy portfolios, with the IAEA highlighting that nuclear energy has prevented approximately 70 gigatonnes of CO2 emissions over the past five decades5.
