Which nuclear fusion company did Trump invest in?

The company is **TAE Technologies**, a U.S. nuclear-fusion startup. The important nuance is that **Donald Trump personally did not directly invest in TAE**. Rather, **Trump Media & Technology Group (TMTG)** - the company behind Truth Social, in which Trump is a major shareholder - agreed to merge with TAE in a deal valued at **more than $6 billion**. TMTG committed up to **$300 million in cash** to TAE. [Trump Media bets on fusion energy with $6 billion TAE deal](https://www.reuters.com/business/trump-media-tae-technologies-combine-6-billion-deal-2025-12-18/?utm_source=chatgpt.com) TAE has been developing fusion technology since 1998 and has raised money from investors including **Google, Chevron, Goldman Sachs, and Sumitomo**.

Donald Trump, through his company **Trump Media & Technology Group (TMTG)**, invested in **TAE Technologies**, a California-based nuclear fusion firm backed by Alphabet (Google’s parent company), Chevron, and other major investors. In December 2025, Trump Media announced a **$6 billion all-stock merger** with TAE Technologies, creating one of the world’s first publicly traded fusion companies. The deal gives Trump Media and TAE shareholders roughly equal ownership (about 50% each) in the combined entity. Trump himself, who owns a large stake in Trump Media, will indirectly hold a significant position in the merged company. The new venture plans to begin construction of the **world’s first utility-scale fusion power plant** in 2026, aiming to generate clean energy to meet the growing electricity demands of artificial intelligence data centers.[Trump Media bets on fusion energy with $6 billion TAE deal | Reuters](https://www.reuters.com/business/trump-media-tae-technologies-combine-6-billion-deal-2025-12-18/)[Trump Media announces merger with fusion firm TAE Technologies - World Nuclear News](https://www.world-nuclear-news.org/articles/trump-media-announces-merger-with-fusion-firm-tae-technologies)[Trump Media to merge with California nuclear fusion company TAE Technologies that wants to power AI in $6 billion deal - ABC7 Chicago](https://abc7chicago.com/post/trump-media-merge-california-nuclear-fusion-company-tae-technologies-wants-power-ai-6-billion-deal/18298408/)[Trump-TAE fusion merger - Nuclear Engineering International](https://www.neimagazine.com/news/trump-tae-fusion-merger/)[Trump Media & Technology to merge with fusion energy company TAE in $6 billion deal.
