General Fusion Group Ltd. had a strong opening day on Nasdaq after completing its merger with Spring Valley Acquisition Corp. III, becoming the first publicly traded company focused exclusively on nuclear fusion energy. The stock, trading under the ticker GFUZ, surged as investors rushed to get exposure to what might be the energy industry’s longest-running “we’re almost there” story.
The merger was first announced back on January 22, 2026, with a pro-forma equity value pegged at approximately $1 billion for the combined entity. The business combination closed in early July, with trading kicking off on July 13.
The financial structure backing this debut is notable. General Fusion secured a committed private investment in public equity, or PIPE, in the range of $105 to $108 million. That PIPE was oversubscribed. On top of the PIPE, the company had access to roughly $230 million sitting in Spring Valley’s trust capital. The net result: General Fusion entered public markets with approximately $150 million in cash to advance its technology.
The Vancouver-based company has spent more than two decades developing what it calls Magnetized Target Fusion, or MTF. Think of it as a middle path between the two dominant approaches to fusion: magnetic confinement (the giant donut-shaped tokamaks) and inertial confinement (blasting fuel pellets with lasers).
