Over a Third of Berkshire Hathaway's $328B Portfolio is in These 3 AI-Focused Stocks

Berkshire Hathaway (NYSE:BRK.A) is a roughly $1.1 trillion company now led by Greg Abel, who succeeded Warren Buffett as chief executive officer on January 1.

Its equity portfolio, valued at an estimated $343 billion as of early July, 2026, has a notable concentration in three holdings whose growth is increasingly shaped by artificial intelligence.

None are traditional AI companies, yet together they could account for more than a third of the portfolio based on recent filings. Here's why, if you follow Berkshire's moves as one way to check up on your financial health, the AI angle matters.

Apple, Berkshire's largest holding

Apple (NASDAQ:AAPL) represented approximately 22% of Berkshire's first-quarter 2026 equity portfolio, making it the single largest stock position by a wide margin, according to the firm's 13F filing with the Securities and Exchange Commission.

The stake is notably smaller than it once was. Buffett sold roughly 75% of Berkshire's Apple shares over nine quarters leading up to his retirement, partly to lock in gains ahead of potential capital gains tax increases, The Motley Fool Reported.

Abel, however, appears committed to keeping the remaining position. In his first annual letter to shareholders, he described Apple as a multidecade compounder.

From Apple Intelligence to Siri AI

Apple launched Apple Intelligence, its on-device generative AI suite in late 2024. At its Worldwide Developers Conference in June 2026, the company unveiled Siri AI, a significantly upgraded voice assistant built on new foundation models developed in partnership with Google's Gemini, Apple confirmed.

Apple faced criticism for delays in rolling out several AI features throughout 2024 and 2025, and whether Apple Intelligence drives a meaningful device upgrade cycle remains an open question.

Coca-Cola, one of Berkshire's oldest positions

Coca-Cola (NYSE:KO) has been a Berkshire holding since 1988, making it one of the longest-tenured positions in the portfolio. It accounted for roughly 11.6% of the first-quarter 2026 equity portfolio, according to the 13F filing with the SEC.

While the stock is primarily known as a dividend-paying consumer staple, Coca-Cola is making a meaningful AI investment behind the scenes.

A $1.1 billion bet on cloud and AI

In 2024, the company committed $1.1 billion over five years to Microsoft's Azure cloud platform, including access to generative AI tools like Azure OpenAI Service, the companies confirmed in a joint press release.

Coca-Cola's chief financial officer, John Murphy, noted that the partnership had grown from a $250 million agreement first announced in 2020, the company reported.

The company has used AI-powered digital assistants to streamline supply chain operations, optimize manufacturing, and enhance marketing, including being among the first major brands to test ChatGPT Enterprise in its workflows, CIO Dive reported.

Coca-Cola's core revenue growth remains tied to pricing power and volume in global beverage markets. AI is unlikely to be the primary driver of top-line growth for a 138-year-old beverage company, even if it helps improve margins and operational efficiency.

Alphabet, Abel's boldest portfolio move

Alphabet (NASDAQ:GOOGL) may be the most revealing window into how Abel plans to manage Berkshire's equity portfolio. Berkshire first disclosed an Alphabet position in the third quarter of 2025, while Buffett was still CEO, and Abel has aggressively expanded it since taking over.

In the first quarter of 2026, Berkshire more than tripled its Alphabet position to nearly 58 million shares worth approximately $17 billion, from 17.8 million shares at year-end 2025, Fortune reported, citing the 13F filing.

Then in June, Berkshire committed another $10 billion through a private placement of Alphabet shares, split evenly between Class A and Class C stock, an SEC filing confirmed.

AI-fueled growth by the numbers

Alphabet's first-quarter 2026 results showed AI-driven momentum across the business, according to the company's earnings report filed with the SEC:

• Google Cloud revenue grew 63% year over year to $20 billion, driven largely by enterprise AI adoption.
• Google Search revenue increased 19%, with management citing AI-powered search experiences as a key contributor to record query volume.
• Total revenue reached $109.9 billion, up 22%, the company's fastest growth rate in over two years.

Alphabet CEO Sundar Pichai told investors the company's AI investments were "lighting up every part of the business," according to the earnings report.

The risk is that Alphabet's planned capital expenditure of $180 billion to $190 billion in 2026 could weigh on margins if AI-driven revenue growth slows.

Several major institutional investors sold their Alphabet positions in the same quarter Berkshire was buying.

Bottom line

Buffett famously avoided technology stocks for most of his career, saying they fell outside his circle of competence. He changed course with Apple in 2016 and with Alphabet in 2025, and under Abel, that technology exposure has expanded significantly.

With Berkshire's cash reserves at approximately $373.5 billion as of March 2026, Abel has flexibility to adjust. But for readers looking to start investing, roughly a third of the portfolio now rides on how well Apple, Coca-Cola, and Alphabet convert their AI investments into sustained growth, a concentration worth watching if you follow Berkshire's moves.
