Berkshire Hathaway Adds $17 Billion to Alphabet Stake

Berkshire Hathaway increased its stake in Alphabet by roughly $17 billion in the second quarter of 2026, buying 48.1 million shares of Google's parent company. It was the fund's largest single investment move of the period, a clear signal that Buffett's money managers are betting on Alphabet as one of the main beneficiaries of the AI boom.

Where the money came from

Nearly 60 percent of the newly purchased shares, about $10 billion, came from a private placement Alphabet announced in June 2026. Berkshire bought the remaining $7 billion on the open market. Earlier this year Alphabet carried out an $85 billion share offering, with the proceeds earmarked for further build-out of AI computing infrastructure, including new data centers.

A bet on infrastructure, not products

The move is notable because Buffett spent years steering clear of technology companies, citing a lack of understanding of their business models. Apple was the exception, treated more as a consumer brand than a tech company. Analysts note that Alphabet appealed to Berkshire for a different reason than typical AI bets: the company generates predictable revenue from search, advertising and YouTube, with AI acting as a multiplier for existing businesses rather than a speculative new product.

Google Cloud, the Gemini models and the company's data center network represent, in this reading, a modern version of the strategy Buffett has applied for decades in other sectors: investing in firms that supply the infrastructure the whole economy needs, rather than betting on single, risky products.

Results that back up the bet

The decision is backed by Alphabet's latest financial results. In the second quarter of 2026, Google Search revenue grew 17 percent year over year, while Google Cloud revenue jumped 82 percent, up from 32 percent growth a year earlier. The company also announced capital expenditures of around $200 billion, aimed mainly at building data centers to handle AI workloads.

Who calls the shots at Berkshire now

The move carries extra weight given the change atop Berkshire Hathaway. Warren Buffett stepped down as CEO in the third quarter of 2025, handing the reins to Greg Abel, though he remains involved in investment decisions. According to Bloomberg, Buffett personally took responsibility for initiating the Alphabet position, unusual for an investor known for emphasizing his team's role in such calls. Some commentators read this as a sign of where the fund's investment philosophy may be heading under Abel.

Alphabet's valuation, at roughly 25 times projected earnings, is moderate by Big Tech standards, fitting Berkshire's traditional criteria for reasonable valuations. The fund has long avoided paying steep multiples for growth, preferring companies that generate stable free cash flow.

Risks on the other side of the bet

The investment isn't without risks. Alphabet faces regulatory pressure in the United States and the European Union, growing competition from Microsoft and OpenAI, and the risk of overinvesting in data centers if demand for AI computing power turns out weaker than forecast. Some market analysts are simultaneously warning of a speculative bubble around AI stocks, which hasn't stopped Berkshire from increasing its exposure right now.

For Polish investors and funds that track Berkshire Hathaway's moves, this can be read as a signal that even funds with a conservative, value-oriented approach to investing are starting to treat AI infrastructure as a durable part of the economy rather than a passing trend. Alphabet is also available through Polish brokerage accounts with access to the US market, making this move directly observable for domestic retail investors.
