TAE Technologies Acquisition
TAE Technologies was acquired by Trump Media & Technology Group for $6B on 18 December 2025.
Before the acquisition TAE Technologies had raised $1.1B across 8 funding rounds.
TAE Technologies, a California-based fusion energy company with over 25 years of research and development, develops next-generation fusion technology that reduces reactor size, cost, and complexity, alongside subsidiaries TAE Power Solutions and TAE Life Sciences. The company has raised more than $1.3 billion from investors including Google, Chevron Technology Ventures, Goldman Sachs, and Sumitomo Corporation of Americas, and received Department of Energy INFUSE funding. Trump Media & Technology Group (TMTG), the Nasdaq and NYSE Texas-listed parent of Truth Social, Truth+, and bitcoin platform Truth.Fi, majority-owned via the Donald J. Trump Revocable Trust (52% stake managed by Donald Trump Jr.), announced a definitive merger agreement with TAE on December 18, 2025. The all-stock transaction, valued at over $6 billion based on TMTG’s trailing 30-day VWAP as of December 17, 2025 (implying $53.89 per fully diluted TAE share), grants each company’s shareholders approximately 50% ownership of the combined entity on a fully diluted basis. TMTG will provide up to $200 million cash at signing and $100 million upon Form S-4 filing. The deal, approved by both boards, expects mid-2026 closing pending shareholder and regulatory approvals, positioning TMTG as holding company for all entities and creating one of the world’s first publicly traded fusion companies. TMTG CEO Devin Nunes and TAE CEO Michl Binderbauer will co-lead as CEOs. Strategic rationale centers on leveraging TMTG’s public market access and capital for TAE’s technology commercialization to achieve U.S. energy dominance, AI supremacy, and manufacturing revival amid data center power demands. The combined firm plans 2026 siting and construction of a 50 MWe utility-scale fusion plant, subject to approvals, followed by 350-500 MWe plants. The transaction faces potential conflict-of-interest scrutiny given Trump family ties and competition from other private fusion developers.
