Fusion startups give government shares for $260M in funding awards

The U.S. government recently awarded $260 million to fusion startups Helion and Commonwealth Fusion Systems (CFS) under the CHIPS and Science Act, according to TechCrunch. Helion received $175 million, while CFS was granted $85 million to develop advanced semiconductors for their fusion reactors.

Unlike traditional government funding that provides nondilutive capital, these awards require the startups to give the government nonvoting shares in exchange, marking a shift in how government support is structured.

This funding comes as the U.S. government renews its focus on fusion energy, a sector that has seen fluctuating support over the years. Both companies have raised billions in private capital, with CFS at about $4 billion and Helion close to $3.2 billion.

The awards signal a renewed government commitment to fusion energy development, even though the amounts are small relative to the companies' total fundraising. Fusion power, which mimics the sun's process of fusing atoms to generate energy, remains a costly and complex technology to develop.
