Warren Buffett has never been one to chase the hot thing. Yet a striking share of Berkshire Hathaway's massive stock portfolio now sits in artificial intelligence names, according to a report from The Motley Fool published July 1, 2026.
The firm's analysis found that 38.6% of Berkshire Hathaway's $328 billion portfolio is concentrated in just three AI stocks. That is a notable degree of concentration for a company famous for its patient, value-oriented approach rather than momentum-driven bets.
As The Motley Fool put it, "chasing momentum was never part of Buffett's philosophy, so you typically won't find Berkshire piling into artificial intelligence stocks." Even so, the outlet reports that at least three of the conglomerate's current holdings qualify as AI plays.
The reporting also notes that Berkshire has, in the words of one summary of the article, "quadrupled down" on one of its AI holdings so far this year — meaning the firm has substantially increased that position rather than trimming it.
The source items available here do not name the three specific stocks or break down how the 38.6% figure is split among them, so those details are not confirmed by the material at hand. The same Motley Fool piece was carried by outlets including The Globe and Mail and appeared via MSN.
Why it matters: Berkshire Hathaway is one of the most closely watched investors in the world, and Buffett's moves are treated as a signal by many ordinary investors — so seeing this much of his portfolio tied to AI suggests even the most cautious money is now heavily exposed to the sector.
