General Fusion, a 23-year-old Canadian startup in the fusion energy industry, laid off at least 25% of its workforce in early May 2025 due to a critical cash shortage. This significant reduction occurred shortly after the company achieved a key technical milestone with its LM26 device, which successfully compressed plasma. CEO Greg Twinney cited an increasingly challenging funding landscape, where investors and governments are navigating political and market uncertainties. Despite raising $440 million from notable backers like Jeff Bezos, the company's unique approach to fusion has struggled to prove viability amid intense competition. With competitors like Commonwealth Fusion Systems securing over $2 billion, General Fusion's financial constraints highlight the extraordinary costs and high stakes in the race for commercial fusion power.
