Berkshire’s Alphabet stake is a bet on the power underneath AI

Berkshire Hathaway has made Alphabet its third-largest common stock holding, and chief executive Greg Abel is framing the position as an AI-infrastructure bet in a CNBC interview from Tokyo, as Carrier Management reports. Abel said he and chairman Warren Buffett authorized an additional $10 billion for Alphabet three months ago, taking shares at a 6.5% discount to market because the Google and YouTube parent is a “significant player” in AI. Buffett opened the position last year, and Berkshire ended June with nearly 106 million shares worth about $37.8 billion, behind only Apple and American Express among its common stock holdings. The cash pool Abel manages with Buffett’s help totaled $364.7 billion as of June 30. The same Tokyo conversation touched the insurance side of the book, with more than 10% stakes in five Japanese trading houses and a 2.49% stake in Tokio Marine taken in March as a strategic partnership.

The investment thesis reaches past the equity into the wires that power it: Abel said Berkshire Hathaway Energy should ride the electricity demand data centers create — he estimated data centers supplied about 8% of the utility’s Iowa load last year — and that he has long held the view that “energy would be the constraint.” That constraint is becoming a familiar one in insurance asset allocation. As this publication’s coverage of Nuveen’s vertical-integration paper laid out, AI-driven power demand is redrawing utility, generation, and grid credit; Berkshire is pricing the same chain from both ends: the utility on its balance sheet, the Alphabet stake in its equity book.

Abel paired the AI enthusiasm with a cautious read on the American consumer, who he said is “still clearly feeling the pain” of elevated inflation and mortgage rates, with housing in for a “bumpy road” near term. Berkshire’s actions mark the bumpiness as short-term: the Alphabet investment was announced on June 1, one day after Berkshire agreed to pay $6.8 billion for homebuilder Taylor Morrison, a company it now owns alongside stakes in Lennar and D.R. Horton. Abel expects Taylor Morrison to be a “very strong asset” in five to ten years, and the Commerce Department’s Census Bureau reported single-family housing starts fell in July to their lowest since November 2022.

For a general account, the sequencing reads as a duration choice, not a momentum trade: the add-on money came in at a discount, the load is sitting inside a regulated utility, and the homebuilder was agreed a day before the equity stake went public. General accounts cannot hold the stack Berkshire holds, and most should not try; the cleaner expression of the same AI cycle sits in the power-and-credit layer beneath the data centers. Watch the two numbers Abel cited: Berkshire Hathaway Energy’s Iowa load share and the monthly single-family starts print. If data-center load keeps climbing while starts keep sliding, the bumpy road runs straight through Berkshire’s third-largest position.
