Our story

Commonwealth Fusion Systems has grown from a foundation of rigorous fusion science into a company that’ll unlock humanity’s boundless potential.

The company was born from the realization that new magnet technology brings an energy revolution into humanity’s grasp. The key innovation: high-temperature superconductors that can drive the powerful magnets that run our fusion machines.

In 2018, CFS was spun out of MIT, combining decades of fusion research with the private sector's speed and agility.

We’ve raised over $2 billion in capital — more than any other fusion energy company — and attracted top talent to design and build commercial fusion power plants. And we’re working with policymakers and suppliers to make fusion energy available globally.

As we push toward, we’ll keep meeting milestones, sharing our progress, and encouraging others to do the same.
