Lead: Founders Fund
Overview
El Segundo nuclear-fuel startup founded in 2024 by Scott Nolan. General Matter is developing uranium enrichment capacity, including high-assay low-enriched uranium for advanced reactors, at a planned site in Paducah, Kentucky. It disclosed a $50 million investment led by Founders Fund in 2025 and a ten-year $900 million DOE agreement in January 2026.
Why General Matter is interesting
Advanced reactor deployment depends on reliable domestic HALEU fuel. General Matter won a $900 million milestone-based Department of Energy agreement, but this is public procurement support, not equity financing.
Product & use cases
General Matter aims to enrich uranium to fuel advanced nuclear reactors, particularly HALEU fuel with uranium-235 enrichment above standard commercial light-water reactor fuel. Its planned U.S. capacity is intended to reduce foreign supply dependency.
- Fuel supply for advanced nuclear energy systems
- Domestic HALEU availability for nontraditional reactor designs
- Energy-security supply chain development
Key facts
- September 28, 2026: General Matter filed its initial NRC Part 70 enrichment-license application for Paducah, Kentucky, describing a two-step plan: initial lower-assay scope, then a future amendment for HALEU.
- January 5, 2026: Department of Energy announced a $900M milestone-based HALEU task order for General Matter; task order is not venture equity.
- April 2025: disclosed $50 million private financing led by Founders Fund.
- January 2026: awarded a $900 million milestone-based Department of Energy agreement over 10 years to support HALEU enrichment capacity; not a venture round.
- September 2026: submitted an initial U.S. Nuclear Regulatory Commission license application; submission is not regulatory approval.
- Plans to build enrichment capacity at Kentucky's former Paducah Gaseous Diffusion Plant.
