Berkshire Hathaway Boosts Alphabet Stake 83% to $37.8B
Berkshire Hathaway Makes Alphabet Its Third-Largest Stock Holding After 83% Increase
Berkshire Hathaway has dramatically increased its investment in Alphabet, the parent company of Google and YouTube, turning the technology giant into the conglomerate’s third-largest stock holding.
According to Berkshire Hathaway’s latest regulatory filing, the company held nearly 106 million Alphabet shares worth approximately $37.8 billion as of June 30, 2026. The position represents an 83% increase from the previous quarter and marks one of the most significant shifts in Berkshire’s stock portfolio in recent years.
The move has attracted significant attention across Wall Street because Berkshire has historically been associated with long-term investments in established businesses, while technology stocks have generally represented a smaller portion of its traditional portfolio.
Information about the major portfolio change has also been highlighted by Cointelegraph, adding to growing market attention surrounding Berkshire Hathaway’s expanding Alphabet position.

Berkshire Hathaway’s Alphabet Stake Surges
Berkshire Hathaway previously held approximately 57.8 million Alphabet shares. By the end of the second quarter, that figure had climbed to roughly 106 million shares.
The Alphabet position was valued at about $37.8 billion at the end of June, according to the regulatory filing. That valuation places Alphabet behind only Apple and American Express among Berkshire’s largest stock investments.
The scale of the increase is particularly notable because Berkshire had only recently begun building its Alphabet position. At the end of 2025, Berkshire held around 17.8 million Alphabet shares valued at approximately $5.6 billion.
That means Berkshire’s exposure to Alphabet has expanded dramatically within a relatively short period.
The development also represents a notable change in the investment strategy associated with Berkshire Hathaway, a company long identified with Warren Buffett’s preference for businesses with strong competitive advantages, durable earnings and substantial cash-generating capacity.
$10 Billion Alphabet Investment Linked to AI Expansion
One of the biggest factors behind Berkshire’s larger Alphabet position was a $10 billion investment agreement announced in June.
Alphabet is seeking to significantly increase spending on artificial intelligence infrastructure, with an approximately $80 billion expansion plan. Berkshire’s investment gives the conglomerate greater exposure to Alphabet at a time when artificial intelligence has become one of the most important investment themes in global markets.
Alphabet has invested heavily in AI infrastructure, cloud computing and advanced AI models through Google and its broader technology ecosystem.
For Berkshire, the investment provides exposure to those trends without requiring the company to directly pick individual AI startups or emerging technology companies.
The strategy also reflects Alphabet’s position as one of the world's largest technology businesses, with major operations spanning internet search, digital advertising, cloud computing, artificial intelligence, video and autonomous driving.
Warren Buffett’s Influence Remains Visible
Although Warren Buffett stepped down as Berkshire Hathaway’s chief executive at the beginning of 2026, the Alphabet investment still carries his influence.
Buffett has previously indicated that Alphabet was an investment idea he supported, while Greg Abel now serves as Berkshire Hathaway’s CEO and oversees the company’s operations and capital allocation alongside Berkshire’s investment leadership. Reuters reported that Buffett had claimed credit for initiating the Alphabet investment.
The development is therefore being closely watched as an early indication of how Berkshire’s investment strategy may evolve under Abel.
For decades, Buffett has often emphasized the importance of investing in businesses with strong economic moats. Alphabet potentially fits that framework through its dominant position in online search, its massive advertising ecosystem, YouTube and its growing Google Cloud business.
The company is also increasingly positioned at the center of the artificial intelligence economy, making its long-term growth prospects particularly important to investors.
Berkshire Becomes More Active in the Stock Market
Alphabet was not the only major change in Berkshire Hathaway’s portfolio during the second quarter.
Berkshire became a net buyer of equities after 14 consecutive quarters in which it had generally been reducing its stock exposure. During the quarter, the company purchased approximately $23.5 billion of stocks while selling about $3.7 billion, according to the latest reports.
The company also increased its investment in Delta Air Lines and expanded its exposure to U.S. homebuilders, including Lennar and D.R. Horton.
At the same time, Berkshire reduced several financial-sector positions and exited its investment in Constellation Brands. These changes suggest that Berkshire is actively reshaping its portfolio rather than simply maintaining the same collection of long-term holdings.
The company’s equity portfolio was valued at approximately $323.8 billion at the end of the second quarter, while its cash and cash-equivalent holdings declined to roughly $364.7 billion.
What Berkshire’s Alphabet Investment Means for Investors
Berkshire Hathaway’s decision to make Alphabet its third-largest stock holding could send an important signal to investors.
The investment does not necessarily mean Berkshire expects Alphabet’s stock to rise rapidly in the short term. Berkshire’s investment philosophy has historically focused on businesses that can generate value over many years rather than short-term market movements.
However, the size of the position indicates that Berkshire sees substantial long-term value in Alphabet.
Artificial intelligence is one of the biggest reasons the investment has captured attention. Alphabet already possesses massive computing infrastructure, a global data network, Google Search, YouTube and Google Cloud. Its investments in AI could potentially strengthen those businesses while creating additional sources of revenue.
The challenge for Alphabet is that the company is operating in an increasingly competitive AI market. Microsoft, OpenAI, Amazon and other technology companies are spending heavily to develop competing AI systems and infrastructure.
Berkshire’s decision to substantially increase its Alphabet stake therefore represents a major vote of confidence in the company’s ability to remain competitive during this technological transition.
A New Era for Berkshire Hathaway
The Alphabet investment also arrives at an important moment for Berkshire Hathaway.
With Greg Abel now leading the company, investors are closely monitoring how Berkshire deploys its enormous capital base. The increased Alphabet position, combined with investments in technology, airlines and homebuilders, suggests that Berkshire is willing to become more active when attractive opportunities emerge.
For Alphabet, meanwhile, Berkshire’s investment provides another major institutional endorsement at a time when investors are debating the long-term value of AI spending.
The $37.8 billion position makes Alphabet one of the most important investments in Berkshire Hathaway’s portfolio and places the technology company alongside long-standing Berkshire holdings such as Apple and American Express.
The move could ultimately become one of the defining investments of Berkshire Hathaway’s transition into the post-Buffett era.
For investors watching Alphabet stock, Berkshire Hathaway’s latest filing offers a clear message: one of the world’s most closely followed investment companies has significantly increased its confidence in Google’s parent company and its future in artificial intelligence.
