In the final month of Warren Buffett’s tenure Berkshire Hathaway has shifted into large tech names tied to AI, opening a new roughly 18 million‑share Alphabet position (worth >$5.5bn) while holding 10 million Amazon shares (~$2.2bn) and 238.2 million Apple shares (~$66bn, ~21% of the portfolio). Alphabet’s dominant ad business ($74.1bn in Q3) is funding heavy investment in Google Cloud, which grew 33% to $15.1bn in Q3 and could expand further if rumored multi‑billion deals (e.g., supplying Meta with TPUs) materialize. Amazon’s 40% U.S. e‑commerce share and $147.1bn in Q3 sales sit alongside a low e‑commerce margin (~4%), but AWS is the profit engine at $33bn (+20% y/y) with ~34% margins. Berkshire’s trimming of Apple (over 680m shares sold since 2023) even as Apple reported fiscal Q4 revenue of $102.5bn (+8% y/y) and pushes its “Apple Intelligence” AI initiative suggests a deliberate move to diversify into cloud/AI exposure while reducing concentration risk.
Warren Buffett is retiring and Berkshire Hathaway materially rotated into large tech names tied to AI: the firm opened an ~18 million‑share Alphabet position worth more than $5.5 billion, holds 10 million Amazon shares (~$2.2 billion) and retains 238.2 million Apple shares valued at roughly $66 billion (about 21% of the portfolio). These moves, executed late in Buffett’s tenure and transitioning to Greg Abel, signal deliberate diversification toward cloud and AI exposure. Alphabet’s advertising business generated $74.1 billion in Q3, funding investments in Google Cloud, which grew 33% year‑over‑year to $15.1 billion in Q3; a rumored multi‑billion deal to supply Meta with TPUs would be a significant catalyst if it materializes. Amazon combines a dominant 40% U.S. e‑commerce share and $147.1 billion in Q3 sales with a thin e‑commerce margin of ~4%, while AWS produced $33 billion in Q3 (up 20% y/y) at ~34% margin, highlighting cloud as Amazon’s profit engine. Berkshire’s sale of more than 680 million Apple shares since 2023, including ~42 million in Q3, reduces concentration risk despite Apple reporting fiscal Q4 revenue of $102.5 billion (+8% y/y) and pursuing its Apple Intelligence AI initiative; key near‑term risks remain execution on AI deals, margin pressure in retail, and confirmation of rumored contracts.
