Fusion is Ready. Is Trump’s Washington?
By Joseph J. Schatz
July 24, 2026

Introduction:

(Politico) DEVENS, Massachusetts — On a rainy July day at Commonwealth Fusion Systems, a former U.S. Army base-turned-research park forty miles northwest of Boston, dozens of material science experts and engineers are intently focused on the task at hand: assembling huge, 10-foot long magnets out of stacks of superconducting copper-colored tape on a massive factory floor.

Specialized welders will soon attach the magnets to a partially-built nuclear reactor, which looks vaguely like something out of the Marvel Cinematic Universe. (Iron Man comes to mind.) To be clear: This isn’t the atom-splitting “fission” reactor most people are familiar with, the likes of which once sparked public fear in the United States and is now experiencing a renaissance. It’s a fusion reactor, nicknamed SPARC, designed to trigger the same atom-fusing reaction that powers the sun.

Creating the pancake-like layers of each magnet “used to take months. Now it takes a shift,” points out Benjamin Byboth, a former Navy nuclear submarine engineer who now runs business development for the company, as he walks me through a tour of the factory.

Commonwealth — an 8-year-old firm that was born at the Massachusetts Institute of Technology and is now the most well-funded of a wave of fusion startups, backed by $3 billion from Bill Gates, Google and other investors — aims to switch on the reactor next year and generate more energy than it took to drive the reaction. It would be the first time a company, as opposed to a government-funded laboratory, has done that. What’s more, executives say, it would prove that fusion is capable of fueling actual power plants and homes — and, yes, data centers — with carbon emissions-free energy by the early 2030s.

That’s a hugely complex goal for a technology that has seen 75 years of fits, starts and elusive progress, a goal that’s “difficult enough to be humbling for everybody,” Byboth says as we walk through the bustling cafeteria, full of PhDs, engineers, tech entrepreneurs and even auto and biotech experts. It’s an orderly, energetic scene of progress that Commonwealth likes to show off to visitors.

Jeff Bezos-backed Fusion Startup General Fusion is Going Public at a $1 Billion Valuation


Introduction:

(Crypto Briefing) General Fusion, the nuclear fusion startup backed by Jeff Bezos, is merging with Spring Valley Acquisition Corp. III in a deal that values the company at approximately $1 billion. If everything goes according to plan, it will become the first pure-play fusion company to trade on public markets.

The deal structure

The SPAC merger was announced on May 22, 2026, with a target close as early as June 2026. General Fusion is aiming for a dual listing on the Nasdaq and Toronto Stock Exchange, a nod to both its Canadian roots and its ambitions to tap into US capital markets.

The financial mechanics break down into two pieces. The company expects $105 million from a public equity investment, commonly known as a PIPE. On top of that, there’s a potential $230 million sitting in the SPAC’s trust account, though that figure is subject to redemptions.

What General Fusion actually does

The company, headquartered in Vancouver, has developed what it calls magnetized target fusion technology. Unlike some of its competitors that rely on lasers or massive magnetic confinement systems, General Fusion’s approach uses mechanical compression to achieve fusion conditions.
General Fusion’s backers include Bezos, Shopify co-founder Tobias Lütke, and the Business Development Bank of Canada.

Pacific Fusion’s next fusion machine could clear a key hurdle to commercial power

8:30 AM PDT · August 25, 2026

Pacific Fusion is one step closer to commercializing fusion power after breaking ground Tuesday on a facility in New Mexico designed to generate as much energy as it consumes.

“It’s a huge step forward for commercial fusion power,” Carrie von Muench, co-founder and chief operating officer at Pacific Fusion, told TechCrunch. “To our knowledge, there’s no such facility being constructed in the country.”

While fusion power startups have been making rapid progress, no experiment or device has been able to generate enough power to offset the energy used by the facility, a milestone the industry calls net facility gain. One device, at the National Ignition Facility, has shown that controlled fusion reactions can generate more energy than they consume, but it is still far short of what would be needed to power the facility.

Pacific Fusion aims to hit net facility gain by 2030, with an eye toward operating a commercial power plant in the mid-2030s. Its commercial-scale reactor will need to generate about five times more energy than the demonstration system, in part to power the additional equipment a power plant requires.
