Things You Gotta Know
Commonwealth Fusion Systems Raises $863 Million in Series B2 to Propel Commercial Fusion
Commonwealth Fusion Systems has secured $863 million in a Series B2 round; the largest raise among deep-tech and energy firms since its $1.8 billion Series B in 2021. The capital will complete the SPARC demonstration machine and advance development of the ARC power plant in Virginia. To date, CFS has amassed nearly $3 billion, roughly one-third of the total private capital invested in fusion worldwide.
Nvidia Joins Google in Funding Commonwealth’s Fusion Power Ambitions
Nvidia’s venture-capital arm has signed on as a new investor in Commonwealth Fusion Systems, joining Google and Khosla Ventures. The infusion of capital and tech-sector backing supports CFS’s effort to complete its fusion demonstration system and move toward its first commercial fusion plant delivering electricity.
General Atomics Commits $20 Million Over 10 Years to Fusion Fuel Cycle R&D
General Atomics has pledged $20 million across a decade to Canada’s Fusion Fuel Cycles Inc., a collaboration between Canadian Nuclear Laboratories and Kyoto Fusioneering. The funding anchors development of UNITY‑2, a fully integrated tritium fuel cycle testing facility slated to be operational by mid‑2026 and critical for commercial fusion viability.
General Atomics Builds World’s Largest Pulsed Superconducting Magnet for Fusion
General Atomics has completed construction of the Central Solenoid, the tallest and most powerful pulsed superconducting magnet ever built. Standing nearly 60 feet tall, the six-module structure will power ITER’s fusion plasma. It symbolizes a huge technological leap for the U.S. and a critical U.S. contribution to this global science endeavor.
Lithium-Based Tritium Breeding and Beyond: Fusion Materials Emerging
Researchers report progress in material innovation, especially lithium-based “breeders” that convert neutrons into tritium, a rare and key fusion fuel. Also in development: ceramic shields and copper alloys designed for extreme heat. These advances, still nascent, are foundational to sustaining fusion reactors at a commercial scale.
The Trump Administration Green-Lights SMRs, and CFS Raises Nearly $1 Billion in New Cash
Commonwealth Fusion Systems secures $863 million in new funding, bringing its total to nearly $3 billion. Meanwhile, the U.S. Department of Energy selects 10 advanced nuclear startups to fast-track small modular reactor (SMR) deployment. Fusion and fission now share the spotlight as the world races to meet exponential electricity demand through next-gen energy sources.
General Fusion: Are They Back In The Game?
General Fusion just closed an oversubscribed $22M funding round. Their Magnetized Target Fusion approach is advancing steadily, with plans to reach scientific break-even by 2026. It’s a meaningful step forward, but commercial fusion is still a long road ahead.
