Warren Buffett: the AI positioning

The thesis, in their own moves

• Q1 2026 brought the pivot: Berkshire exited Amazon entirely and boosted Alphabet by 225%, while leaving Apple untouched — shifting its AI exposure from e-commerce and cloud toward search and full-stack AI.
• Buffett — and Abel's team taking the reins — still buys compounding businesses inside the circle of competence. But Q1 cut the book from 40 names to 26 with 15 full exits, sharply concentrating the portfolio.
• The 225% Alphabet increase is Berkshire's clearest AI statement: search cash flow, Gemini, and in-house TPUs — full-stack AI still valued below the pure-play AI names.

Frequently asked questions

Yes, but through businesses rather than pure-play AI names. As of the Q1 2026 13F, Berkshire's AI-adjacent exposure runs through Apple (~22%, the largest holding, unchanged that quarter) and Alphabet, which was increased 225%. Amazon was fully exited.

The 225% increase is Berkshire's clearest AI statement to date: Alphabet pairs search cash flow with Gemini and in-house TPUs — a full-stack AI position still valued below pure-play AI names, which fits the circle-of-competence and valuation discipline Berkshire has always applied.

Neither, on the evidence. The Q1 2026 book concentrated from 40 names to 26 with 15 full exits — the discipline is valuation and certainty, not narrative. Berkshire bought the AI business it could value and exited the one it could not justify.
