General Fusion Begins Trading on Nasdaq as Public Fusion Company

General Fusion began trading on the Nasdaq stock exchange on Monday under the ticker GFUZ. The company is now the first publicly listed fusion power entity, surpassing competitor TAE Technologies, which reportedly has Trump's backing, by several months.

The stock saw a rally as trading commenced, increasing by 40% from its opening price of $12.85 as of 12:50 p.m. ET. General Fusion had announced in January 2026 its intention to merge with Spring Valley Acquisition Corp. III, a transaction that was finalized last week.

While the fusion power company could have added up to $230 million to its balance sheet without redemptions, most de-SPAC deals experience significant redemptions before closing. This merger was no exception, and although the company has not disclosed specific figures, it is likely that redemptions substantially reduced its available capital.

General Fusion employs a Magnetized Target Fusion (MTF) approach in its reactor design. The company projects that within 20 years, its initial commercial power plant could generate 1000 MW of electricity. Previously, General Fusion secured substantial private funding, including a $100 million round that concluded in 2022. As a publicly traded entity, the company is now positioned to access further capital from the market to finance the construction of its first commercial fusion facility.
