Every fusion startup that has raised over $100M

The article highlights the recent surge in investment and technological progress in private fusion energy startups, which are moving fusion power closer to commercial viability. Fusion, long considered perpetually decades away, is now gaining momentum due to advances in computing power, AI, and high-temperature superconducting magnets, enabling more sophisticated reactor designs and control systems. A key milestone was achieved in late 2022 when a U.S. Department of Energy lab produced a controlled fusion reaction reaching scientific breakeven, confirming the underlying science. This progress has energized startups to pursue commercially relevant fusion power plants that could disrupt massive energy markets. Several fusion startups have raised over $100 million, with three notable companies leading the charge. Commonwealth Fusion Systems (CFS), backed by investors like Bill Gates and Breakthrough Energy Ventures, has raised $2 billion and is developing the Sparc tokamak reactor in Massachusetts, aiming for a commercial-scale plant called Arc in the early 2030s.
