Quarterly 13F filings for the September quarter show billionaire managers concentrating new positions in three AI-exposed mega-cap names—Alphabet, Nvidia and Meta—signaling where top institutional capital is positioning ahead of 2026. Berkshire Hathaway and Coatue led heavy buying in Alphabet (Berkshire added ~17.85M Class A shares), underpinned by Google’s dominant search/ad franchises, fast-growing Google Cloud (~30% YoY) and roughly $98.5B of cash; Nvidia drew purchases from David Tepper and Dan Loeb as its GPUs and CUDA ecosystem maintain a powerful moat for AI compute (though the piece flags bubble risk); and Meta attracted new stakes from Coatue, Third Point, Druckenmiller and Viking, leveraging ~3.54B daily users, ad-driven economics and ~ $44.5B in cash as it integrates generative AI into advertising. The activity underscores billionaire conviction in top AI platform and infrastructure plays while also highlighting concentration risk and the dependence of future returns on successful AI monetization and broader market sentiment.
Quarterly 13F filings for the September quarter show concentrated buying by billionaire managers into three large-cap AI plays: Berkshire Hathaway added 17,846,142 Class A shares of Alphabet, Appaloosa’s David Tepper bought 150,000 NVDA shares in Q3 on top of earlier purchases, and multiple managers (Coatue, Third Point, Druckenmiller, Viking) opened or added sizeable stakes in Meta (examples: Coatue 355,090 shares; Viking 663,504 shares). These moves reflect where top institutional capital is positioning ahead of 2026 rather than broad market rotation. Fundamental drivers cited in the article support the allocations: Alphabet benefits from search/ad dominance and a Google Cloud segment growing about 30% year-over-year with ~$98.5 billion in cash; Nvidia retains a dominant AI-GPU position and a sticky CUDA software ecosystem that underpins customer lock-in; Meta monetizes ~3.54 billion daily users with ~98% ad revenue and held ~$44.5 billion in cash while integrating generative AI into ad tooling. Risks noted include concentration risk and a flagged possibility of an AI bubble impacting valuation-sensitive names in 2026; the piece rates sentiment as moderately positive with a modest market-impact score, implying conviction but limited broad-market spillover unless monetization or demand metrics deteriorate.
