Warren Buffett Just Revealed He -- Not Greg Abel -- Made Berkshire's Big Alphabet Bet. Should You Follow Him In?

Warren Buffett disclosed he personally drove Berkshire Hathaway's $31 billion stake in Alphabet, ending speculation that the bet originated with his lieutenant Greg Abel. The Oracle of Omaha called it a mistake not to have bought the search giant sooner, though he flagged concerns over the AI arms race now consuming tech balance sheets.

Alphabet posted 22% revenue growth in Q1 2026, with Google Cloud accelerating 63%. But the company plans to spend $180-190 billion annually on capital expenditures, a figure that has Buffett and other investors weighing growth potential against profitability headwinds. The massive outlay reflects Alphabet's push to compete in AI infrastructure and model development.

Buffett's endorsement carries weight—Berkshire rarely takes tech positions of this scale—but his unease over spending discipline matters just as much. The tension between Cloud momentum and capex burn will define whether GOOGL can justify its valuation as AI investments mature.
