Among the investors participating in the round were Chevron, Google and New Enterprise Associates (NEA), along with other new and existing stakeholders.
The option remains open for TAE to secure additional funds as part of this round.
AE’s total equity capital raised since inception now exceeds $1.3bn, further endorsing the company’s unique approach to achieving commercial fusion.
In early 2025, TAE announced a significant breakthrough with its “Norm” technology, which achieved stable plasma at temperatures exceeding 70 million degrees Celsius in a simplified fusion device.

By GlobalDataThis advancement is a step forward in enhancing the performance and reactor-readiness of TAE’s fusion tech.
TAE’s collaboration with Google, which began in 2014, has been instrumental in reaching this milestone.
Together, they have utilised advanced machine learning to expedite fusion science, resulting in improved plasma lifetime and performance.
TAE Technologies CEO Michl Binderbauer stated: “Fusion has the potential to transform the energy landscape, providing near-limitless clean power at a time when the world’s energy needs are growing exponentially due to the growth of AI and data centres.
“TAE’s technology uses the soundest physics to deliver superior performance in a compact machine, with attractive economics and best-in-class maintainability. We are leading the charge to develop revolutionary fusion technology for full-scale commercial deployment.”
Google engineers have been integrated into TAE’s teams, co-developing sophisticated plasma reconstruction algorithms.
Google’s ongoing support reflects a comprehensive technical and commercial evaluation of TAE’s fusion approach, as detailed by Ross Koningstein, founder of Google’s nuclear energy research and development group, on the Google blog.
The fusion systems developed by TAE promise on-demand, carbon-free, utility-scale power without the risks associated with traditional nuclear power, such as meltdowns or long-lived radioactive waste.
This safety profile allows TAE fusion power plants to be located in diverse settings, from densely populated areas to remote regions or near large data centres.
“We’re delighted to continue our relationship with Google, which has not only provided funding to TAE but collaborated closely in research and development over many years. With this latest fundraise, we look forward to accelerating our efforts to deliver commercial fusion power,” Binderbauer added.
TAE’s technological prowess is evidenced by its portfolio of more than 1,500 patents worldwide and the successful construction of five prototype generations.
The last four prototypes are comparable in size to traditional natural gas combustion turbines, with two additional prototypes currently in development.
