Commonwealth Fusion Systems
An MIT-spinout fusion energy company building the SPARC demonstration reactor, aiming to prove commercial-scale fusion power ahead of a planned Virginia power plant that has already agreed to sell electricity to Google. CFS installed the first of 18 superconducting magnets into SPARC by CES 2026, and in January 2026 partnered with NVIDIA and Siemens to build an AI-powered digital twin of the SPARC machine using NVIDIA Omniverse and OpenUSD to accelerate simulation-driven commercial fusion development.

Commonwealth Fusion Systems's Timeline
A sourced, dated history of Commonwealth Fusion Systems's key moments — founding to present.
Jan 2018 · Founded
Commonwealth Fusion Systems was founded as an MIT spinout to commercialize high-field superconducting magnet fusion technology.
Jan 2026 · NVIDIA/Siemens digital twin partnership
CFS announced a collaboration with NVIDIA and Siemens to build an AI-powered digital twin of its SPARC fusion reactor using NVIDIA Omniverse and OpenUSD, aimed at accelerating commercial fusion development through simulation.
Jul 2026 · SPARC reaches 75% completion after vacuum vessel installation
Commonwealth Fusion Systems installed a roughly 106,000-pound (53-ton) steel vacuum vessel half-ring into SPARC, the chamber that will hold plasma hotter than the sun's core, bringing the reactor to nearly 75% completion; the company continues to target first plasma in 2026 and net fusion energy (more energy released than used to heat the fuel) in 2027.
