What companies are developing nuclear fusion?

``` The deep research logic is organized as follows: Okay, let's tackle this question: "What companies are developing nuclear fusion?" The user is asking for a list of companies involved in nuclear fusion development. First, I need to check the provided references to find relevant information. Looking through the references, Number 1 lists 33 fusion energy startups as of September 2025. The top entries include companies like Focused Energy, Helical Fusion, EX-Fusion, NT-Tao, Commonwealth Fusion, TAE Technologies, Helion Energy, General Fusion, and Zap Energy. These are all startups, mostly from the US, Japan, and Israel. The funding amounts vary, with Commonwealth Fusion having the highest at $2B. Then, in reference Number 6, there's a query result mentioning BWXT (BWX Technologies) as a company involved in nuclear fusion. The table shows BWXT with stock details and mentions their involvement in nuclear components and small modular reactors. However, the user's question is about companies developing nuclear fusion, so BWXT might be more of a supplier rather than a developer of fusion reactors. References 12, 13, and 14 mention Commonwealth Fusion Systems (CFS) signing a $1B power deal with Eni and Google. This indicates that CFS is a significant player in the fusion energy sector, moving towards commercialization. Similarly, TAE Technologies (Numbers 32, 33, 34) has raised substantial funding and achieved plasma breakthroughs, positioning them as a leader in the field. EX-Fusion (Numbers 17, 18, 19, 20, 21) is highlighted as a Japanese company developing laser-based fusion reactors, with recent funding rounds and partnerships with institutions like Tokyo Tech. Their focus on commercialization and scalability is notable. NT-Tao (Numbers 22, 23, 24) is an Israeli startup working on compact fusion systems, supported by grants from the Israel Innovation Authority. Their approach is compact and scalable, targeting various markets like data centers and remote communities. Helion Energy (Number 1) is another US-based company aiming to deliver clean electricity through fusion. They have raised $1B in funding, which is substantial. General Fusion (Number 1) is a Canadian company using Magnetized Target Fusion (MTF) technology, aiming for utility-scale power generation. They have secured $370.5M in funding. Zap Energy (Number 1) is another US startup focusing on fusion, though details are limited in the provided references. Additionally, the user's profile shows interest in high-growth tech stocks and forward-thinking industries, so highlighting companies with significant funding, partnerships, and commercialization progress would align with their interests. Companies like Commonwealth Fusion, TAE Technologies, and EX-Fusion stand out due to their recent deals, breakthroughs, and strategic partnerships. I should structure the answer by listing these companies, providing key details like their approach, funding, and recent developments. Using tables to organize the information would make it clear and concise. Also, including a visualization for the query result from reference 6 would enhance the presentation as per the user's requirements. Need to ensure all citations are correctly formatted and that the answer doesn't include any fabricated information. The conclusion should summarize the key players and their significance in the fusion energy sector, aligning with the user's interest in innovative and high-potential companies. ``` ### 🌟 **Conclusion** The nuclear fusion sector is rapidly evolving, with **Commonwealth Fusion Systems**, **TAE Technologies**, and **EX-Fusion** leading the charge as key players in commercializing fusion energy.
