- • Citadel Advisors reduced its stake in Nvidia by 79% last quarter (dumping 9.28 million shares), despite the chipmaker remaining a significant AI infrastructure play amid the ongoing artificial intelligence rally.
- • Ken Griffin's hedge fund simultaneously cut stakes in Microsoft and Amazon, signaling a potential tactical shift away from mega-cap AI beneficiaries despite these stocks' dominant market positioning.
- • Citadel maintained or increased exposure to Tesla and Meta, indicating Griffin's conviction in alternative narratives within the AI ecosystem beyond traditional chip and cloud infrastructure plays.
- • These portfolio adjustments reflect a sophisticated rebalancing strategy among top-tier institutional investors, with peers including Tiger Global and Adage Capital also trimming AI-heavy positions during a period of elevated valuations.
- • The moves underscore investor skepticism about whether near-term valuations for mega-cap AI stocks fully reflect the billions in capital deployment, even as foundational AI demand remains intact.
Summary
Ken Griffin's Citadel Advisors significantly reduced its exposure to three of the market's most prominent artificial intelligence beneficiaries in recent quarters, executing a portfolio rebalancing that contradicts the broader institutional rush into AI infrastructure stocks. Most notably, the $67 billion hedge fund cut its Nvidia position by 79%, offloading 9.28 million shares, despite Nvidia remaining central to AI chip demand. Simultaneously, Citadel trimmed stakes in both Microsoft and Amazon, two companies that have accumulated substantial valuations based on enterprise AI adoption and cloud computing exposure.
The reductions arrive amid a powerful market rally in technology and AI-related equities, with analyst firms including Citi and Susquehanna raising price targets on Nvidia ahead of earnings announcements. However, the moves signal that even sophisticated mega-fund managers question whether current valuations reflect reasonable risk-reward dynamics. Griffin maintained or increased allocations to Tesla and Meta Platforms, suggesting he sees differentiated value or alternative AI narratives in companies beyond the traditional mega-cap infrastructure play.
Citadel's portfolio adjustments align with broader institutional behavior, as other major fund managers including Tiger Global and Adage Capital have similarly trimmed holdings in Nvidia and Amazon during the same period. This pattern indicates a potential inflection point in how the world's largest investors view the sustainability of current AI stock valuations relative to underlying earnings trajectories. While these funds remain exposed to the AI theme through diversified holdings—these five mega-cap stocks collectively represent 42.6% of Citadel's disclosed portfolio—the tactical reduction suggests conviction in valuation discipline over momentum continuation. As major technology companies report earnings, the market will test whether the billions deployed in AI infrastructure justify near-term stock price levels, a question that Griffin's rebalancing implicitly raises.
