Commonwealth Fusion Systems Secures $863M to Commercialize Fusion Power

Commonwealth Fusion Systems (CFS), a fusion energy startup, has raised $863 million in a Series B2 funding round, bringing its total funding to nearly $3 billion—the most for any fusion startup. The round included participation from prominent investors like Nvidia, Google, and Breakthrough Energy Ventures. This investment will fuel the development of Sparc, CFS's prototype reactor, aiming for scientific breakeven by 2027. Following this milestone, construction of Arc, a commercial-scale power plant, is slated to begin in 2027 or 2028. Despite the multi-billion dollar cost of Arc, CFS has already secured a deal with Google to purchase 200 megawatts of its power, demonstrating significant market confidence in the technology.
