Even the most legendary investors have their moments of regret, and for Warren Buffett, one such moment was not investing in Alphabet (GOOG, GOOGL) earlier. This might come as a surprise, given Buffett's historical aversion to tech investments.
However, the Oracle of Omaha confessed in a CNBC interview that he had indeed "made a mistake" by delaying his investment in the search giant. Now, under the leadership of incoming CEO Greg Abel, Berkshire Hathaway (BRKA, BRKB) is taking a proactive stance to ensure it doesn't miss out on Alphabet's future growth, particularly in the burgeoning field of artificial intelligence.

Berkshire's Growing Conviction in Alphabet
Berkshire Hathaway initiated its position in Alphabet during the third quarter of 2025, acquiring approximately 18 million shares. Demonstrating a clear strategic shift, CEO Greg Abel significantly expanded these holdings in the first quarter of 2026 by adding roughly 40 million more shares. Not stopping there, Abel further solidified Berkshire's commitment in June through a private placement deal, investing an additional $10 billion – split equally between Class A and Class C shares.
While Berkshire typically maintains a quiet profile regarding its investment rationale, these recent aggressive moves under Abel's guidance offer profound insights. They not only signal strong confidence in Alphabet but also serve as a broader validation for investing in artificial intelligence (AI).
Validating the AI Investment Thesis
The initial fervor surrounding AI investments moderated somewhat in 2026, largely due to escalating concerns about the substantial capital expenditures required by companies. Alphabet, for instance, projects its capital expenditures to be between $195 billion and $205 billion this year.
A prevailing fear is that such massive investments in AI might take longer than anticipated to yield returns, or worse, fail to pay off entirely. However, Berkshire's significant and repeated investments in Alphabet under Abel's leadership provide a powerful endorsement, suggesting that AI is far more than just a fleeting trend. According to Statista, the global AI market is currently valued at just over $617 billion in 2026 and is forecasted to soar to $1.2 trillion by 2032.
Beyond the broader AI narrative, this investment is a direct vote of confidence in Alphabet itself. Warren Buffett's investing philosophy emphasizes a disciplined, long-term approach, rarely chasing missed past opportunities. If Berkshire Hathaway is investing in Alphabet today, it underscores a deep conviction that the company will continue to appreciate significantly over time.
While some investors might find Alphabet a less exciting prospect amidst "Magnificent Seven" fatigue, its performance speaks volumes. Should it continue to meet the high expectations set by Abel and Berkshire, Alphabet could maintain its trajectory of meaningfully outperforming the broader market. Over the last five years, Alphabet stock has surged approximately 164%, significantly outpacing the S&P 500, which climbed around 70% during the same period.
