Berkshire's $38 billion Alphabet stake is a governance disclosure, not a tech bet

Berkshire Hathaway's quarterly portfolio update, released Friday, showed about 106 million Alphabet shares worth nearly $38 billion at the end of June, its third-largest equity holding behind Apple and American Express ^[1][2]. The number is interesting as a tech position and more interesting as a governance document: Greg Abel took the chief executive job at the turn of the year, when Warren Buffett ended his six-decade run ^[3], and the person publicly claiming the trade is the one who left.

Buffett said in a July interview that he initiated the position in the third quarter of 2025 ^[4], while he was still CEO. Business Insider reports he is likely responsible for building the stake from scratch in under 12 months, and that part of the ramp came through a $10 billion private placement at a discount to the market price in June ^[5][6]. That June purchase landed roughly six months into Abel's tenure ^[7]. Nobody has said who authorized it. Berkshire did not immediately respond to a request for comment ^[8].

David Kass, a University of Maryland finance professor who blogs about the company, told Business Insider he believes Buffett is "still largely managing Berkshire's stock portfolio" alongside investment manager Ted Weschler, and that "he comes into the office every day, and investments are his primary interest" ^[9]. That is one outside observer's read, not a company statement. But the quarter's activity is consistent with it. Berkshire bought a net $23.5 billion of stocks in three months, largely because of Alphabet, after being a net seller in each of the previous 14 quarters going back to 2022 ^[10]. It repurchased $4.5 billion of its own stock, its biggest buyback quarter since 2021, having bought back nothing for the preceding 18 months ^[11]. It agreed in May to buy homebuilder Taylor Morrison for $8.5 billion in cash, closing in late July ^[12].

The cash pile fell from a record $380 billion to $365 billion ^[13], a decline of $15 billion ^[14] against roughly $28 billion of stock purchases and buybacks ^[15]. Buffett had nearly tripled that hoard in his final three years in charge ^[16]. Business Insider notes valuations did not crash to levels that would obviously have triggered him ^[17]. So a firm that spent three years refusing to deploy reversed itself in a single quarter, without an external price shock to point at, in the first two quarters after the title changed hands.

For any board running a handover, this is the part worth copying down. The reserved matter here is not a veto over strategy; it is capital allocation itself, the only function Berkshire's structure really asks of the center. If the Alphabet position works, the credit is ambiguous. If it does not, so is the accountability. And the market still has no evidence of how Abel allocates when he is the one deciding, which is a test that has been deferred rather than passed. Buffett turns 96 later this month ^[18], and he has hedged the thesis himself, telling CNBC in July that Alphabet was "more likely to be a winner based on their record than probably 95% of what gets merchandised through Wall Street" while flagging the hundreds of billions its peers are spending on AI infrastructure: "That's real money. That's the game they're playing now" ^[19][20].

Watch the next filing for whether the Alphabet stake grows, and watch whether Berkshire ever attributes a large purchase to Abel by name. Until it does, the succession has moved the title and not the decision rights.
