What General Matter does

General Matter is a privately held American uranium enrichment company founded in 2024 and publicly launched in April 2025, headquartered in San Francisco. Its core business is producing Low-Enriched Uranium (LEU, 3–5% U-235) and High-Assay Low-Enriched Uranium (HALEU, 5–20% U-235) from uranium hexafluoride gas using a novel, scalable, cost-competitive enrichment process that targets the middle step of the nuclear fuel production cycle. The company operates two physical sites: a 100-acre multi-decade DOE lease at the former Paducah Gaseous Diffusion Plant in Kentucky (the first privately developed, U.S.-owned enrichment facility, with a $1.5B planned investment and 140 expected jobs targeted to begin operations by 2030) and a 190,000 sq ft lease at the Hanford Site's Fuels and Materials Examination Facility (FMEF) in Washington State for advanced fuel production evaluation.

The company serves three primary customer segments: the U.S. Department of Energy under a 10-year, $900M milestone-based IDIQ contract for HALEU enrichment to support advanced reactors and national security; Japanese nuclear utilities via up to $2.4B in EXIM Bank-backed financing; and South Korean nuclear utilities via up to $1.8B in EXIM-backed financing. Revenue mechanics are therefore government-managed services and EXIM-financed allied export sales, with no consumer-facing or self-serve channel and no publicly disclosed per-unit pricing. Marketing is content- and PR-driven via the company's news page, Substack essays, X/Twitter presence, and earned coverage in Reuters, Bloomberg, Forbes, and Fortune.

General Matter is venture-backed, having raised $50M in April 2025 led by Founders Fund (with Peter Thiel joining the board) and is listed alongside IQT (In-Q-Tel) as an investor. The team is drawn from SpaceX, Tesla, Anduril, national labs, the DOD, and special forces, and the company explicitly markets itself on its ability to "break into stagnant sectors and unlock their potential." Its mission framing positions enrichment capacity restoration as essential to U.S. energy security, AI-driven compute scaling, and reduction of foreign (Russian and Chinese) dependence on nuclear fuel.

Revenue model

1. U.S. Department of Energy IDIQ contract: 10-year, milestone-based Indefinite Delivery, Indefinite Quantity (IDIQ) contract worth up to $900 million to build and operate HALEU enrichment capacity at the former Paducah Gaseous Diffusion Plant in Kentucky. Part of a $2.7B DOE enrichment program.
2. Export of enriched uranium to Japan: Sale of American-enriched uranium to Japanese utilities, supported by up to $2.4 billion in EXIM Bank financing under the Indo-Pacific Energy Security Ministerial.
3. Export of enriched uranium to South Korea: Sale of American-enriched uranium to South Korean nuclear utilities, supported by up to $1.8 billion in EXIM Bank financing.
4. Kentucky Nuclear Energy Development grants: State grants (capped at $2 million each) from the Kentucky Nuclear Energy Development Authority (KNEDA) to support nuclear fuel production in Paducah.

Core offering

General Matter produces enriched uranium fuel (LEU at 3-5% U-235 and HALEU at 5-20% U-235) using novel, scalable, cost-competitive enrichment technology applied to uranium hexafluoride gas. The company performs the middle "enrichment" step of the five-step nuclear fuel production cycle through its flagship Paducah facility in Kentucky and a secondary Hanford FMEF site in Washington, supplying domestic and allied nuclear utilities and the U.S. government.

Product overview

General Matter is a single-line American uranium enrichment company — a vertically integrated, facility-anchored operation rather than a modular software platform. Its core offering is the production of enriched nuclear fuel (HALEU and LEU) using novel, scalable, cost-competitive enrichment technology, organized around two physical sites that together form its production footprint: the flagship Paducah Uranium Enrichment Facility in Kentucky (the nation's first privately developed, U.S.-owned enrichment plant) and the Hanford FMEF site in Washington State, which General Matter is reactivating to support advanced fuel production. Commercial outputs are HALEU (5–20% U-235) and LEU (3–5% U-235), supplied under a $900M DOE IDIQ contract to U.S. advanced reactors and via EXIM-backed letters of interest to allied utilities in Japan and South Korea.

Products and services

• HALEU (High-Assay Low-Enriched Uranium) Enrichment Capacity High-Assay Low-Enriched Uranium (5-20% U-235) production capacity that General Matter is building under a $900M, 10-year IDIQ contract with the U.S. Department of Energy, intended to supply U.S. advanced reactors, restore domestic fuel production, and reduce reliance on Russian/Chinese HALEU. Sold to government and advanced reactor operators.
• LEU (Low-Enriched Uranium) Supply Low-Enriched Uranium (3-5% U-235) supply from General Matter's expanding enrichment capacity, sold to allied nuclear utilities (Japan, South Korea) backed by EXIM letters of interest, and positioned to serve existing commercial reactors and the next generation of reactors.
