Now, in a move that marks the end of a long-standing regret, Warren Buffett’s Berkshire Hathaway has officially entered the Google era, acquiring a staggering $4.3 billion stake in its parent company, Alphabet, during the third quarter of 2025 . This isn’t just another portfolio addition; it’s a full-circle moment that finally closes the book on what Buffett himself has called one of his biggest tech blunders.
The decision, detailed in Berkshire’s latest 13F filing, reveals a new position of approximately 17.8 million shares . It’s a strategic pivot that speaks volumes about the evolving landscape of value investing and Berkshire’s growing confidence in the future of artificial intelligence and digital advertising.

The 21-Year Regret: Why Buffett Missed Google
Warren Buffett is famous for his disciplined value investing principles, but even the greatest can have their blind spots. Google, which went public in 2004, was one of them. For years, both Buffett and Munger have been candid about this oversight. “Our biggest tech failure was missing Google,” Buffett once admitted . Munger was even more direct, stating they regretted not investing in Google more than they did missing Amazon .
Their rationale was classic Buffett: a perceived lack of a durable “moat” and an inability to confidently predict the company’s long-term economics in its early, hyper-growth phase . They understood insurance and railroads, but the complex, rapidly evolving world of internet search was outside their circle of competence at the time—a line they famously refuse to cross.
Why Now? The Strategic Shift Behind the Warren Buffett Alphabet investment
So, what changed in 2025? The answer is simple: time and undeniable proof of dominance. After 21 years, Alphabet’s position as the world’s undisputed leader in search and digital advertising is no longer a speculative bet; it’s a fact. Its “moat” is now a fortress, guarded by immense network effects, user data, and a near-monopoly in its core market .
This Warren Buffett Alphabet investment represents a maturation of his view on tech. It’s no longer about betting on potential but investing in proven, cash-generating juggernauts—a strategy he perfected with his massive Apple stake. Alphabet, with its robust balance sheet and consistent profitability, finally fits the Berkshire mold .
The GEICO Connection: A Firsthand Lesson in Google’s Power
One of the most compelling reasons for this investment came from within Berkshire’s own ecosystem. Buffett has repeatedly cited his experience with GEICO, Berkshire’s auto insurer, as a key factor in his changing perspective on Google .
GEICO is one of the largest advertisers on Google, spending millions on those familiar “10-per-click” search ads. This firsthand, on-the-ground experience gave Buffett undeniable proof of Google’s platform’s immense power and effectiveness . He wasn’t just reading about Google’s success; he was paying for it and seeing the results in his own company’s customer acquisition. This practical, internal validation was likely the final piece of the puzzle.
AI and the Future of Search: Buffett’s New Bet
Beyond its established dominance, this investment is also a clear vote of confidence in Alphabet’s ambitious foray into artificial intelligence. With its Gemini platform and deep integration of AI into its core search product, Alphabet is positioning itself at the heart of the next technological revolution .
By investing now, Berkshire is not just buying into a mature advertising business but also gaining exposure to one of the world’s leading AI developers. This forward-looking perspective shows that the 95-year-old investor is still keenly attuned to the future, ensuring Berkshire’s portfolio remains relevant in a rapidly changing world.
Impact on Berkshire’s Portfolio and the Apple Trade-Off
The Alphabet stake doesn’t exist in a vacuum. Reports indicate that this purchase was partially funded by further trims to Berkshire’s long-standing position in Apple [[4], [10]]. This strategic reallocation is fascinating. It suggests a diversification within the tech sector, moving from a hardware and services play (Apple) to a pure-play on digital advertising and AI infrastructure (Alphabet).
This move adds a crucial new dimension to Berkshire’s portfolio, balancing its traditional holdings with a stake in the company that powers much of the internet’s economy. It’s a calculated risk that blends Buffett’s old-school value principles with a pragmatic embrace of the 21st-century digital landscape.
With a stake representing about 0.31% of the company , Berkshire is now a significant, if not controlling, shareholder, ready to benefit from Alphabet’s continued growth.
Conclusion: A Legacy Investment for a Post-Buffett Era
The Warren Buffett Alphabet investment is more than a financial transaction; it’s the closing of a historic chapter. It’s the Oracle of Omaha finally acknowledging a past mistake and using his immense capital to correct it. This move signals a strategic evolution for Berkshire Hathaway, showing a willingness to adapt its definition of “value” to encompass the undeniable economic power of the digital age. As Berkshire looks toward a future beyond Buffett, this investment in a stable, innovative, and cash-rich tech titan like Alphabet is a smart, legacy-defining play that ensures the conglomerate’s continued strength for years to come.
