Warren Buffett Said 'I Initiated It.' The 13F Can't Say Whose Idea Berkshire's Trades Are

In July, six months after he handed Berkshire Hathaway's CEO title to Greg Abel, Warren Buffett did something a retired chairman rarely needs to do: he got on CNBC to claim credit for a stock purchase. "I initiated it," he said of Berkshire's big stake in Alphabet, stepping past the natural assumption that the new man bought it. He was 96. He works in the office five days a week anyway.

That is odd, and the oddness is the story. A chairman does not typically need to run damage control on attribution — unless the market is reading the move as a signal about the next era of Berkshire, and the only public window into the trade can't tell anyone whose trade it was.

The 13F can't say whose idea it was.

That window is the quarterly 13F filing, a list of every U.S. stock Berkshire owns, published roughly six weeks after the quarter ends. It is strictly anonymized: it names the company, never the person. So when the filing showed Berkshire growing its Alphabet stake 83% in the second quarter to about 106 million shares worth roughly $37 billion, the reader had no way to know if that was Abel's first big swing or Buffett's. The classification question — whose judgment are you actually following? — is invisible in the disclosure that everyone is following.

Attribution has to come from somewhere else, and Buffett volunteered it himself. He initiated the Alphabet position in the third quarter of 2025, kept adding, and much of the June jump came from a $10 billion purchase of Alphabet shares bought — an off-market private placement inside Alphabet's larger $85 billion raise, shepherded along, per Bloomberg, by a weekend call from Goldman Sachs. This is a structured deal, not Buffett dribbling into the open market. Alphabet is not even his favorite holding: "I don't like it as well as at least four or five other businesses that we own," he said, adding that he regretted not buying years earlier and that he worries about the "hundreds of billions" competitors are spending on AI.

There are two different "calling the shots" questions.

Ignore the headlines that flatten this into "Buffett still runs it" or "Abel runs it now." Berkshire's equity book — some $350 billion of stocks on top of a cash pile that topped $365 billion — is governed by at least two layers of authority, and they are transferring at different speeds.

The first layer is initiative: who names the big strategic bet. That has not transferred. Buffett identified Alphabet, and he frames Abel as the gatekeeper rather than the originator. "I am not doing anything that he doesn't approve of. He's not doing anything I don't approve of. We talk all the time, but he is the decider." So Abel holds the veto and the title; Buffett still supplies the ideas that move the market. Even the Delta Air Lines add in the quarter is credited by Barron's to the portfolio manager Ted Weschler, not to either of them.

The second layer is the machinery — the structure of who runs the money — and there the transfer is real, and it is rewriting Buffett's own design. Buffett's stated succession plan had been to hand the portfolio to his two lieutenants, Todd Combs and Ted Weschler. Instead, Combs left Berkshire in December for a job at JPMorgan and will not be replaced; Abel has been selling off the positions Combs ran (Barron's estimates those sales could total about $15 billion); and by Abel's first shareholder letter, he personally manages roughly 94% of the portfolio, with Weschler cut to about 6%. Two managers became one.

What that means for reading the next 13F.

There is a genuine regime change underneath all this — it is just located in a different place than the Alphabet headline suggests. Berkshire swung from net seller to net buyer of stocks for the first time in 14 quarters, buying about $20 billion more than it sold, stepped up buybacks to $4.5 billion from $235 million the prior quarter, and agreed to buy homebuilder Taylor Morrison for $6.8 billion. Cash fell from a record $397 billion to $365 billion. That is Abel's do — the operator, long criticized for under-deploying Buffett's mountain, finally moving it. It is a decision about deployment (buyback, acquisition, buying the dip), not a statement of new stock taste; the taste in the biggest bet still has Buffett's fingerprint.

And that is the reading error worth guarding against. When you follow Berkshire's 13F as "the smart money's picks," you are actually pricing several different judgments at once — Buffett's residual taste on the big bets, Weschler's on a sliver, and Abel's on structure and deployment — all disclosed without attribution. The useful question is less "did Abel buy Alphabet" and more "whose judgment survives when the last giant is gone." On that score the portfolio is becoming more concentrated in fewer brains, not less: the second of Buffett's two intended managers is gone and not replaced, the remaining specialist is down to six percent, and the new CEO has no formal portfolio-management background. The Buffett signature is a real asset being spent for as long as he works five days a week — and it does not transfer to Abel by title.
