Berkshire Hathaway (NYSE: BRKA) (NYSE: BRKB) has historically shied away from making splashy investments in the technology sector. Long-time followers of this company know that it tends to focus on businesses within the consumer staples, energy, and financial services sectors, which have revenue and earnings that can be easier to predict years into the future.
But the Omaha-based conglomerate of 2026 is setting itself up for a world in which technology continues to have a greater impact on the economic backdrop. And it's betting on some well-known companies.

As of Sept. 16, 30.7% of Berkshire Hathaway's $365 billion public equities portfolio is invested in these two artificial intelligence (AI) stocks. Greg Abel, who became CEO at the start of this year, has clearly indicated that he has a bullish view of these dominant businesses.

1. Apple: up 1,050% in the past decade
The first AI stock on the list is also the largest holding in Berkshire Hathaway's portfolio, even after the company trimmed the position considerably in recent years. The conglomerate first bought Apple (NASDAQ: AAPL) in the first quarter of 2016. It has probably been Warren Buffett's most lucrative capital allocation decision. In the past decade, the Magnificent Stock has surged more than 1,000%.
Investors who are closely following the AI boom might not immediately consider Apple a top way to bet on this trend, especially since it isn't shelling out hundreds of billions of dollars in annual capital expenditures to build data centers. However, this business is in one of the best positions to be a leader in consumer adoption of AI.
Apple's devices remain the primary method for people to access their digital lives. On the Q1 2026 earnings call, then-CEO Tim Cook said there were more than 2.5 billion active Apple devices around the world, an all-time high. This gives the company a powerful physical distribution advantage.
In particular, the iPhone is arguably what makes Apple an elite AI enterprise. Demand remains robust, as this single product line posted 21.7% year-over-year sales growth last quarter (ended June 27) to $54.3 billion. That represented 49.6% of Apple's overall revenue.
The business recently launched Siri AI, which offers new capabilities that can help people get more done. It's part of Apple Intelligence, the company's suite of AI features embedded in the most popular existing apps. It seems reasonable to assume that, as consumers interact with various AI tools more often going forward, this usage will occur on Apple hardware.
2. Alphabet: up 37% in the past year
In the third quarter of last year, Berkshire Hathaway turned heads in the investment community when it revealed that it had purchased shares in Alphabet (NASDAQ: GOOGL) (NASDAQ: GOOG), the internet juggernaut that owns Google Search and YouTube, among numerous other platforms. Since that first buy, the conglomerate has upped its stake. Between class A and class C shares, Alphabet accounts for 10% of Berkshire Hathaway's portfolio.
Shares have soared 37% over the past 12 months, even though they are 14% off their mid-May peak. At a forward price-to-earnings ratio of 22.4, Alphabet's valuation is significantly cheaper than Apple's 34.6 multiple.
There is no denying that Alphabet is at the forefront of the AI revolution. It's involved in almost every phase of this budding industry. It has a top research lab in Google DeepMind. It designs chips internally, called Tensor Processing Units. Google Cloud Platform is firing on all cylinders thanks to strong demand among enterprises for access to powerful compute resources. Segment revenue skyrocketed 82% in Q2 (ended June 30) compared to the same period in 2025.
The business has its Gemini family of AI models. And perhaps most importantly, Alphabet is integrating its AI capabilities into its various apps for billions of users, as well as for its advertising customers.
It's interesting that Greg Abel-led Berkshire Hathaway initiated its Alphabet position at a time of heightened capital expenditures. Omaha is betting on a bright future for this tech titan.
