Berkshire Hathaway has added another $10 billion to Alphabet, deepening a bet on the Google parent just two days after announcing a $6.8 billion homebuilder acquisition. The move pushes Berkshire’s total Alphabet position to more than $31 billion and makes it the fourth-largest holding in the conglomerate’s portfolio.
The purchase lands in a market that is still searching for clues about how Berkshire plans to deploy its nearly $400 billion in cash and equivalents. Investors following stock market today also have another reason to watch the name: Alphabet is selling $80 billion of shares to help fund artificial intelligence-related capital expenditures, and Berkshire is buying into that plan while the stock sits near all-time highs.
Berkshire bought $5 billion of Alphabet class A voting shares at an average cost of $351.81 apiece and another $5 billion of class C shares at an average cost of $348.20. At the time of the latest purchase, class A shares were trading around $363 and class C shares around $360, leaving the company paying up for a position it had already enlarged sharply in the first quarter of 2026.
That is what makes the timing notable. Berkshire has spent the past five years mostly avoiding the AI trade, preferring to keep its balance sheet loaded with cash rather than chase the hottest part of the market. Now it is buying Alphabet as the company raises money for the very computing buildout that has pulled so many other large investors toward the sector. The reversal is especially striking because Berkshire started buying Alphabet in 2025, when Warren Buffett was still chief executive, and the latest expansion comes under Greg Abel’s direction.
Alphabet’s appeal is not hard to see. Google controls about 90% of global search market share, and its advertising business remains one of the most powerful cash engines in technology. Even so, the company has been under pressure from regulators, after a federal judge ruled that Google operated as a monopoly in its digital advertising and search businesses, though the judge stopped short of forcing it to divest Chrome or strip away other practices that helped build that market power.
For Berkshire, the new purchase says as much about patience as it does about conviction. After years of sitting out the AI frenzy, the conglomerate is choosing one of the market’s biggest winners at a time when the price is high, the business is still dominant and the capital demands are growing. What remains unclear is how much of the Alphabet push is Abel’s own call and how much reflects a strategy that began under Buffett, but the size of the position now leaves little doubt that Berkshire sees more room in the stock even after the run-up.
