Citadel's technology portfolio: billions at stake in the AI bet

The third wallet disclosed by Ken Griffin in 2025 reveals a bold strategy: Citadel allocated approximately US$ 4.2 billion to solidify its presence in tech giants and innovation leaders. The numbers do not lie about the fund’s priorities.

Microsoft and Meta in the spotlight

The most significant move involved Microsoft, where Citadel added 1.99 million shares worth US$ 1.03 billion. This is not just a conventional bet: it’s a firm stance in the artificial intelligence market that dominates industry conversations. Simultaneously, Meta received equal strategic attention, with 1.95 million shares totaling US$ 1.43 billion in expenditure.

Apple, NVIDIA, and Alphabet: the tech trio

Apple was not left out of this capital reorganization. Griffin increased exposure to Apple by US$ 652 million through an additional 2.56 million shares. Meanwhile, increased positions in NVIDIA and Alphabet indicate that Citadel remains attentive to movements shaping the future of computing, especially in emerging technologies that blend meme culture and innovation in modern investors’ minds.

Strategic reduction and niche diversification

Not everything was expansion. Amazon experienced a 39% reduction in holdings—a decision contrasting with aggressive increases in other assets. This selectivity reflects a mindset of reshaping: discarding the established in favor of the promising.

Diversification also included small positions in Rigetti and D-Wave, both focused on quantum computing, as well as the biotech company Summit Therapeutics. These smaller investments indicate exploration of disruptive technological niches.

What does all this mean

Griffin’s 13F report paints a picture of a manager in tune with current market realities: AI is no longer speculation, it’s infrastructure. The movement of US$ 4.2 billion is not noise—it’s capital allocation where Citadel sees the next decade of returns.
