Last year, fusion power startup General Fusion was struggling to raise funds, laying off at least 25% of its staff before receiving a $22 million lifeline investment while it figured out how to keep the company afloat.
Today, General Fusion revealed its survival plan: it will go public through a reverse merger with an special purpose acquisition company, Spring Valley III, combined with additional investment from institutional investors. It’s a significant change in fortunes for a company whose CEO wrote a public letter just last year pleading for funding.
If the deal closes as planned, General Fusion could receive up to $335 million from the transaction, more than double what it was reportedly seeking to raise last year before it landed the $22 million lifeline.
The transaction will value the combined company at about $1 billion, General Fusion said. Before the merger was announced. The fusion startup, which was founded in 2002, had previously raised over $440 million, according to PitchBook.
General Fusion plans to use the money to complete its demonstration reactor, Lawson Machine 26 (LM26). The device uses an approach called “inertial confinement,” which works by compressing a fuel pellet until its atoms fuse together, releasing energy in the process. The National Ignition Facility used inertial confinement in its successful fusion experiments, using lasers to bombard the fuel pellets to unleash the compressive force.
LM26 eschews the lasers, though. Instead, it uses steam-driven pistons that drive a wall of liquid lithium metal inward to compress the fuel pellet. That liquid lithium then circulates through a heat exchanger, which generates steam to spin a generator. By avoiding expensive lasers or superconducting magnets, which are required in other fusion reactor designs, General Fusion hopes to build a fusion power plant for less money. But first the company has to prove its approach is viable.
Last year, before it revealed its financial problems, General Fusion said that in 2026, LM26 would hit scientific breakeven, in which a fusion reaction generates more power than was required to start it. Scientific breakeven is a key milestone, though distinct from and easier to attain than commercial breakeven, in which fusion reactions release enough energy to export electricity to the grid. General Fusion did not reply to a request asking if its timeline had change.

The acquisition company, Spring Valley, is something of a specialist in reverser mergers with energy companies. It previously took NuScale Power, a small modular nuclear reactor company, public in a deal whose stock price has since fallen more than 50% from its peak last year. The firm is also in the midst of completing a merger with Eagle Energy Metals, a uranium mining company that’s also supposedly developing its own SMR.
General Fusion isn’t the first fusion company to go public. In December, TAE Technologies announced it would merge with Trump Media & Technology Group in a deal valuing the combined company at more than $6 billion.
The common thread connecting these deals is data centers, of course. They’re expected to consume nearly 300% more power by 2035, according to BloombergNEF, and General Fusion explicitly points to rising data center energy demand in its merger announcement.
But the company also pointed to broader electrification trends, including EVs and electric heating, that could increase overall electricity demand by up to 50% by 2035. It’s a reminder that, while the Trump administration has cast doubts on an electrified future, other countries are charging ahead. While General Fusion may face technological challenges, trends in the energy world suggest that if it can deliver fusion power at a reasonable cost, it will find plenty of willing buyers.

![A24 Wants You to Be Nice About Its Google AI Deal
Earlier this week, we learned A24 entered a research partnership with Google’s DeepMind unit. The reactions were… not happy, to say the least. And like many who’ve let generative AI into their hearts, the film studio’s now left playing defense for its widely panned decision. In a statement to Wired, A24’s communications rep Sophia Shin stressed the “research” part of its Google partnership. “We’re working side-by-side with DeepMind’s researchers to learn, iterate, and build, having an active hand in shaping new tools and workflows,” she explained. “This is about learning and helping pain points in workflows behind the scenes. […] It exists because we want to dictate what tools get built for artists, so they have a voice in shaping them rather than having tools handed to them. While acknowledging A24 doesn’t love “any of the current AI outputs onscreen in Hollywood,” Shin considers this partnership a bit of a necessary evil. “We’d rather have a seat at the table than on the sidelines,” she stated. The promise of further artist agency and “a seat at the table” are common shields from genAI users, but it doesn’t seem to be working here. Fans consider this move ironic and a betrayal, given Backrooms director Kane Parsons recently called the tech “cultural and economic rot” and wished he could just snap it out of existence.
Before that, the studio didn’t seem to have much interest in generative AI. In 2024, it came under fire for using the tech to create posters for Civil War, while months later, its horror film Heretic had a disclaimer promising it wasn’t made with the technology. But Hollywood’s become gradually more accepting of generative AI and its supposed potential for the filmmaking process. In that sense, maybe it was inevitable for A24 to fall in line.
