Realta Fusion has formed a strategic partnership with Commonwealth Fusion Systems (CFS) for the design and manufacturing of high-temperature superconducting magnets to accelerate commercialisation of Realta's magnetic mirror fusion energy systems. The agreement, potentially worth multiple billions of dollars, covers magnets for demonstration prototypes and commercial fusion power plants. CFS will leverage its expertise to support design, manufacturing, deployment and operation of magnets for Realta's compact, scalable, modular fusion systems. The partnership formalises a relationship dating to 2020, when CFS provided magnets for the University of Wisconsin-Madison's WHAM experiment, which achieved a world-record 17 tesla magnetic field strength in 2024. Realta, backed by Khosla Ventures and Future Ventures, is one of eight companies in the US Department of Energy's Fusion Milestone Programme.

OpenAI in talks with Helion Energy to secure fusion power supply. OpenAI CEO Sam Altman is understood to be holding conversations with Helion Energy as the artificial intelligence company seeks to buy fusion energy. Fusion energy, which mimics the Sun's process of energy creation, offers AI companies like OpenAI a potential source of abundant clean energy. Altman is reportedly in discussions to lock in a fixed share of Helion's output, starting at about 12.5%, sources told Axios. The proposed agreement would give OpenAI access to roughly 5 gigawatts of power by 2030, with plans to scale that up to 50 gigawatts by 2035. Helion aims to achieve "scientific breakeven," where the energy produced surpasses the energy consumed, a milestone no private firm has yet reached, according to Axios. The agreement with OpenAI is still in its early stages, with numerous conditions pending, such as determining a production site for Helion's energy generation. Meanwhile, Helion has already secured a power purchase agreement with Microsoft for 50 megawatts and competes with Commonwealth Fusion Systems, which has deals with Google. Don't Miss Altman, who has invested in Helion, has stepped down from his role as the company's board chair and is not participating in these negotiations, sources told the publication. Altman, who led Helion's $500 million Series E funding round in 2021, owns a significant, though undisclosed, stake in the company. In January 2025, Helion announced a $425 million Series F funding round. Investors included Lightseed Venture Partners, Softbank, Sam Altman, Mithril Capital and Capricorn Investment Group. OpenAI has also presented a 17.5% return for private equity investors as it seeks to establish joint ventures aimed at expanding enterprise AI adoption. Last week it was reported that OpenAI is set to significantly expand its workforce this year. OpenAI has been making significant strides. In February, the company secured $110 billion in a private round, with a pre-money valuation of $730 billion, setting the stage for a potential blockbuster IPO. 3 'Safe' Stocks You Probably Own That Are About to Get Crushed by Tariffs They look stable.

Commonwealth Fusion Systems accelerates commercial fusion with Siemens and nvidia, leveraging ai-powered digital twins. News provided by. As part of this initiative, CFS will use the data generated and compiled through the use of the Siemens Xcelerator portfolio of industrial software to build its SPARC fusion machine. A visual illustration of the digital twin will be unveiled at CES 2026 in Las Vegas. DEVENS, Mass., Jan. 6, 2026 /PRNewswire/ - Commonwealth Fusion Systems (CFS), the largest and leading private fusion company, today announced collaborations with NVIDIA and Siemens to develop a digital twin of its SPARC fusion machine that will apply artificial intelligence (AI) and data and project management tools to accelerate commercial fusion. The digital twin will leverage troves of data from the Siemens Xcelerator portfolio of industrial software, including its Designcenter NX for advanced product engineering and Teamcenter product lifecycle management (PLM) tools, which CFS uses to create, catalog, and process machine designs and assemblies. These designs and assemblies can then be used in CFS' modeling and simulation workflows, including the layering of AI-enabled tools. CFS will use NVIDIA Omniverse libraries and OpenUSD to integrate data with classical and AI-powered physics models to create the digital twin of SPARC. This virtual replica of SPARC will provide CFS with a user-friendly way to run simulations, test hypotheses, and quickly compare the experimental results from the machine to the simulations. This ability to rapidly analyze data and iterate will speed CFS' efforts to make fusion energy a commercial reality. "CFS will be able to compress years of manual experimentation into weeks of virtual optimization using the digital infrastructure developed by NVIDIA and Siemens," said Bob Mumgaard, Co-Founder and CEO of CFS. "Through this collaboration, we're demonstrating how AI and integrated digital engineering can accelerate progress from design to grid power. This will allow us to transform how we build and operate fusion machines in the race to commercial fusion." "Delivering commercial fusion demands that we simulate and solve incredibly complex physics problems," said Rev Lebaredian, Vice President, Omniverse and Simulation Technology, NVIDIA. "By using Siemens NX software and NVIDIA Omniverse libraries to create a high-fidelity digital twin of SPARC, CFS will be able to accelerate its engineering and shorten the timeline to clean power." CFS is also using Siemens' digital tools to improve the efficiency of its manufacturing processes and operations at the company's magnet factory in Devens, Massachusetts. "By connecting Siemens Xcelerator with NVIDIA AI visualization libraries, we're demonstrating that end-to-end digital workflows aren't just efficient, they're transformative," said Del Costy, president and managing director, Americas, Siemens Digital Industries Software. "Fusion is complex, but data doesn't lie. When you aggregate real manufacturing intelligence, apply AI, and run thousands of scenarios, you remove guesswork and accelerate innovation. This is the future of industrial engineering." About Commonwealth Fusion Systems Commonwealth Fusion Systems is the world's largest and leading private fusion company.
