Fusion Energy

Global private investment in nuclear fusion hit a record $4.48 billion in 2025, up 69% from a year earlier, as major energy companies like Eni, Equinor, Chevron, Shell, and Cenovus ramp up their commitments. Eni plans to deploy a commercial fusion power plant in Europe by the early 2040s, building on its investment in Commonwealth Fusion Systems and a $1 billion agreement to buy electricity from the startup's first U.S. plant. Eni is also forming a joint venture with the UK Atomic Energy Authority to develop fuel systems for fusion reactors, targeting a large-scale tritium fuel-cycle facility by 2028. Commonwealth Fusion Systems raised another $1 billion in July, bringing its total funding to $4 billion, and its planned 400-MW ARC facility in Virginia is the first fusion project to apply for grid interconnection. Chevron has backed TAE Technologies and Zap Energy, while Shell invested in Zap's $130 million Series D round, and Cenovus's early bet on General Fusion is moving toward a Nasdaq listing.

Trump Media & Technology Group and Crypto.com have terminated their planned US$6.42 billion digital-asset treasury venture, citing ethics concerns and regulatory scrutiny around Donald Trump's crypto-related business interests. The cancellation shifts Trump Media's priorities back to its core media operations and a proposed merger with fusion-energy firm TAE. The retreat removes a speculative piece of the investment narrative and reduces regulatory noise, but fundamental issues around scale, profitability, and governance remain. Attention now turns to the upcoming Q2 2026 earnings update and progress on closing the TAE combination, with execution risk and cash burn still in focus.

General Fusion will ring the Nasdaq Opening Bell on July 17, 2026, to celebrate the start of trading as the first publicly listed fusion energy company. The bell-ringing ceremony will be livestreamed on Nasdaq's official channels at 9:30 a.m. EDT. General Fusion's CEO Greg Twinney said the move to public markets puts the company in a strong position to bring its practical fusion technology to the world. The company's MTF approach aims to achieve fusion without superconducting magnets or high-powered lasers, and its LM26 demonstration machine, built in under two years, is the first MTF machine at commercially relevant scale, mechanically compressing plasma with a lithium liner at 50% commercial-scale diameter.

General Fusion Group Ltd. will ring the Nasdaq Opening Bell on July 17, 2026, celebrating its debut earlier this week as the first publicly listed fusion energy company. The ceremony will be livestreamed at 9:30 a.m. EDT. CEO Greg Twinney said the public listing strengthens the company's position to commercialize its magnetized target fusion technology, which avoids superconducting magnets and high-powered lasers. General Fusion's LM26 demonstration machine, built in under two years, is the first MTF device at commercially relevant scale and aims to achieve key milestones including plasma temperatures of 100 million degrees Celsius and ultimately net fusion energy.

Global private investments in nuclear fusion hit a record $4.48 billion in 2025, a 69% surge driven by AI data center energy demands and rising energy security concerns. The Fusion Industry Association reports that about 71% of fusion companies now expect to deliver commercial power to the grid by the 2030s, with firms inking site selections and power purchase agreements with major tech companies. Helion Energy signed a binding power purchase agreement with Microsoft for at least 50 megawatts by 2028, backed by a $465 million Series G round that valued the company at $15.5 billion, and broke ground on its Orion facility in Washington. Commonwealth Fusion Systems raised $863 million in an oversubscribed Series B2 round, bringing its total funding to nearly $3 billion, to develop its SPARC demonstration device and design the ARC commercial plant in Virginia. Proxima Fusion raised €411 million, becoming Europe's best-funded fusion company at a €2.4 billion valuation, with Google and RWE each contributing €25 million to accelerate its stellarator-based Alpha demonstrator near Munich.

General Fusion has completed its business combination with Spring Valley Acquisition Corp. III, a special purpose acquisition company, and will begin trading on Nasdaq under the ticker GFUZ on July 13, 2026. The company enters the public markets with approximately US$150 million in cash, including net proceeds from a private placement and trust capital, to advance its Magnetized Target Fusion technology. The funding is expected to support the Lawson program through key technical milestones targeted for completion in 2028, aiming to demonstrate and de-risk the technology in a commercially relevant way. General Fusion currently operates Lawson Machine 26, the first MTF demonstration machine built at a commercially relevant scale, designed to achieve critical fusion milestones including plasma heating to 10 keV and ultimately the Lawson criterion.

Alphabet's Google and German utility RWE have invested in nuclear fusion startup Proxima Fusion as part of a €411 million funding round. Alphabet participated as a strategic investor, extending its reach into long-term, carbon-free energy solutions beyond its core technology operations. The investment aligns with rising AI-related power demand and long-term decarbonization goals, positioning Alphabet closer to future sources of baseload power that could support Google Cloud and Gemini. This move diversifies Alphabet's external partnerships into energy infrastructure, setting it on a slightly different path from peers like Microsoft and Amazon, which rely more heavily on traditional renewables and grid contracts today.

American Fusion Inc., through its subsidiary Kepler Fusion, is advancing the Texatron, a compact aneutronic fusion engine designed to produce from 0.5 megawatt to more than 100 megawatts of clean power without turbines or steam cycles. The company is currently testing a 5-megawatt preproduction unit, with engineering and production underway for 10-megawatt and 20-megawatt follow-on systems. The technology targets military energy resilience by eliminating vulnerable fuel supply chains, as the U.S. Department of Defense consumes roughly 4.6 billion gallons of fuel annually, with delivery costs reaching $400 per gallon in remote combat zones. American Fusion also sees commercial applications in data centers and industrial operations, offering a power-as-a-service model, and notes that the broader fusion energy market is projected to grow from $288 billion in 2025 to $419.84 billion by 2030. The Texatron uses a fast-pulsed Torsatron design and deuterium-helium-3 fuel, achieving direct energy conversion with theoretical efficiencies above 90%, and the company is expanding its intellectual property portfolio across plasma confinement, reactor architecture, and modular deployment.

Munich-based fusion energy company Proxima Fusion has completed a €411 million funding round, bringing its valuation to €2.4 billion and making it the best-financed fusion company in Europe. The round was led by XTX Ventures and East X Ventures, with participation from Google and a €25 million investment from German energy company RWE. Proxima, a spin-out from the Max Planck Institute for Plasma Physics, is developing quasi-isodynamic stellarator technology and plans to build a net-energy demonstrator called Alpha near Munich in partnership with the state of Bavaria, the Max Planck Institute, and RWE. The company has now secured over €650 million in total funding since its 2023 founding, including €95 million in public grants, and aims to complete Alpha in the early 2030s ahead of a first commercial plant later that decade.

British trading billionaire Alex Gerko's firm XTX Markets has led a €411 million investment round in Germany's Proxima Fusion, Europe's largest ever nuclear fusion investment. Google and East X Ventures also participated in the round. Munich-based Proxima aims to demonstrate fusion power in the early 2030s and build a commercial plant by the end of the decade, positioning itself as Europe's champion against US rivals. The company is also seeking hundreds of millions of euros from German government bodies and has partnered with RWE to build a stellarator plant in Bavaria.

Mitsubishi Electric Corporation, Kyoto University's Institute of Advanced Energy, and the National Institute for Fusion Science have developed an advanced microwave plasma measurement system for fusion energy. The system can simultaneously measure plasma conditions at multiple points over extended periods and was successfully demonstrated using the Heliotron J fusion experimental device at Kyoto University. The collaborators aim to promote plasma diagnostics technologies necessary for practical fusion energy implementation, which the Japanese government supports with a target of power generation demonstrations by the 2030s.
