This capital raise is the single largest funding round among fusion energy companies worldwide since CFS announced its $1.8 billion Series B round in 2021. With this capital, and the $863 million the company raised last year, CFS has now raised a total of $4 billion. This $4 billion represents about 30 percent of the total capital raised by the fusion industry to-date, reinforcing CFS' position as the world's largest and leading fusion company.

Commonwealth Fusion Systems is the world's largest and leading private fusion company. The company's marquee fusion project, SPARC, will generate net energy, paving the way for limitless carbon-free energy. The company has raised $4 billion in capital since it was founded in 2018.
