Commonwealth Fusion Systems focuses on developing fusion energy as a clean and sustainable power source. The company utilizes advanced magnet technology, created in partnership with MIT, to build smaller and more affordable fusion systems called tokamaks. These devices use magnetic fields to confine plasma, making them an efficient method for achieving fusion. Currently, CFS is manufacturing high-temperature superconducting magnets and constructing SPARC, which aims to be the first commercially viable net energy fusion machine. The success of SPARC will lead to the development of ARC, the first fusion power plant. CFS differentiates itself from competitors by its commitment to scientific integrity and a mission-driven approach, ensuring that the best ideas are prioritized. The company's goal is to provide cost-competitive fusion energy to help combat climate change.

Startups in the fusion energy sector have raised a total of $7.1 billion, with companies like Commonwealth Fusion Systems securing over $100 million each. These investments are driving advancements in high-temperature superconductors and AI-driven plasma control, bringing commercial fusion energy closer to reality. Despite technical challenges, experts believe fusion could transform global energy markets within a decade, reducing reliance on fossil fuels.
Commonwealth Fusion Systems has raised over $1 billion in its Series B2 round to advance its ARC fusion reactor, bringing total funding to nearly $3.8 billion. The company aims to deliver fusion power by the early 2030s. Additionally, Germany has shifted its stance on nuclear power, aligning with France to support nuclear energy in EU legislation under Chancellor Friedrich Merz. The Nuclear Company also raised $51 million to develop large-scale reactor campuses.
Commonwealth Fusion Systems has reportedly raised $1 billion in an extension of its Series B round to support the buildout of its demonstration fusion power reactor... University of Wisconsin spinout Realta raised $36 million for its modular magnetic mirror fusion technology.
Commonwealth Fusion Systems (CFS) has raised over $1 billion, led by an unnamed hyperscale data center developer, to build 400MW fusion reactors within a decade. CFS plans to construct the 'ARC' fusion power plant in Virginia by the early 2030s and aims to have a test system, 'SPARC,' by 2027. Despite challenges in fusion investments, CFS secured funding, while other companies like First Light Fusion and General Fusion face financial difficulties.
CFS has been developing SPARC step by step for years.
