OMAHA, Neb. — Berkshire Hathaway more than tripled its stake in Google parent Alphabet — vaulting the search giant to Berkshire's third-largest equity holding — and bought $2.6 billion worth of Delta Air Lines shares in the second quarter, according to a securities filing released Friday, offering the clearest look yet at how Chief Executive Greg Abel is reshaping a $280 billion portfolio in his first year running the company Warren Buffett built.

The 13F disclosure to the Securities and Exchange Commission also shows Berkshire pruned or exited positions in Visa, Mastercard, Domino's Pizza, Amazon and UnitedHealth Group, and opened a small $55 million stake in Macy's. Combined with a $6.8 billion all-cash acquisition of homebuilder Taylor Morrison announced Sunday and a follow-on $10 billion Alphabet purchase disclosed Monday, the moves mark the sharpest tonal shift since Abel took over from Buffett at the start of the year.

The tech turn

Buffett long resisted technology investments — Apple the notable exception — because he said he could not predict the long-term winners. Abel appears more comfortable. By the end of March, Berkshire owned nearly 58 million Alphabet shares worth almost $17 billion, up from 17.8 million shares worth $5.6 billion three months earlier. Alphabet on Monday became the fourth Big Tech company to cross a $4 trillion market cap, a run driven by its Gemini model and its cloud-AI unit.

At the wheel

Berkshire also picked up roughly 40 million Delta shares in the first three months of the year, a bet that runs against Buffett's own history of dumping airline stocks. The trims to Visa, Mastercard, Amazon and UnitedHealth followed the late-2025 departure of investment manager Todd Combs, one of two lieutenants Buffett had hired to help run the book.

Abel's Taylor Morrison deal, at $72.50 per share, carries a 24 percent premium over the homebuilder's previous $58.50 close, and Abel signaled a departure from Buffett's hands-off model by telling shareholders he expects to "unify our site-built homebuilding operations into a combined platform" with Berkshire's existing Clayton Homes unit. Buffett, still chairman and Berkshire's largest shareholder, praised the CEO on CNBC on Monday.

"Greg did that faster than I could have done it, smoother than I could have done it, and I never talked to the CEO," Buffett said. "He has launched."

The missing voice

Analyst commentary in the wires has skewed positive. CFRA Research's Cathy Seifert called the Taylor Morrison price "rich given the current interest rate/macro environment" but framed the M&A push as something investors would "cheer." Absent from the reporting is a bearish take on Abel adding a further $10 billion to Alphabet at a $4 trillion valuation — a level even Chief Executive Sundar Pichai has conceded reflects some market "irrationality."

Berkshire does not comment on portfolio moves. Its next 13F filing is due in mid-November.
