Berkshire Hathaway’s AI Stock Portfolio in 2026

For six decades, Warren Buffett ran Berkshire Hathaway with one unbreakable rule: invest only in businesses you understand, with durable competitive advantages, and hold them for decades. He called it his “circle of competence.” Semiconductors, cloud servers, and AI chips were firmly outside that circle.

And yet, as of May 2026, more than 37% of Berkshire Hathaway’s $330 billion portfolio is sitting in just three stocks with deep AI exposure. The man who avoided Google for 20 years built the foundation for what is now one of the most AI-exposed large institutional portfolios in America — and his successor, Greg Abel, is pushing even further in that direction.

This article breaks down exactly what’s in Berkshire’s AI portfolio right now, how it got there, what Greg Abel changed in Q1 2026, and what it all means for investors watching one of the world’s most closely followed holding companies navigate the most important technological shift of the century.

A New Era: Warren Buffett Steps Down, Greg Abel Takes Over

At the end of 2025, Warren Buffett officially stepped down as CEO of Berkshire Hathaway after a 60-year run that turned a $500 investment in 1965 into over $24.2 million by the time he left. His successor, Greg Abel, had been groomed for the role for years. Abel is a longtime Buffett disciple — same investment philosophy, same long-term orientation, same preference for cash-generating businesses over speculative growth plays.

But Abel has wasted no time putting his own stamp on the portfolio. The Q1 2026 13F filing, released in May, was described by analysts as one of the most dramatic single-quarter portfolio overhauls in Berkshire’s history. Abel exited roughly 16 positions entirely, cutting the portfolio from 42 holdings down to just 29. He sold out of Visa, Mastercard, UnitedHealth, Amazon, Domino’s, and over a dozen other names — companies that were well-established Buffett positions. He then took the proceeds and concentrated them in a smaller number of higher-conviction bets, with one name standing above all others: Alphabet.

The 3 AI Stocks Now Dominating Berkshire’s Portfolio

1. Apple (AAPL) — 20.7% of the Portfolio

Apple remains Berkshire’s single largest holding by a wide margin, representing 20.7% of the entire $330 billion portfolio. That’s a position worth roughly $68 billion, making Berkshire one of Apple’s most significant institutional shareholders even after the heavy selling Buffett did through 2024 and 2025.

At its peak, Apple accounted for nearly half of Berkshire’s entire equity portfolio — a concentration that even Buffett acknowledged was too heavy. He sold around three-quarters of the position between 2023 and 2025, cashing in gains while corporate tax rates remained favorable and reducing portfolio risk. The sales drew attention but Buffett was clear: he hadn’t lost faith in Apple. He told CNBC the company could potentially buy more at the right price.

Apple’s AI story is centered on its Apple Intelligence platform, which debuted with the iPhone 16 lineup and has since expanded across iPads and Macs. The hardware is equipped with custom-designed neural chips that run Apple’s AI features locally on the device — a privacy-focused approach that differentiates it from cloud-dependent AI. Apple Intelligence includes advanced writing tools, an upgraded Siri assistant integrated with OpenAI’s ChatGPT, and AI-powered photo and video editing capabilities.

With over 2.5 billion active Apple devices worldwide, the company’s distribution advantage in AI is unmatched. While competitors like Google and Microsoft fight over enterprise AI contracts, Apple is quietly becoming the largest AI delivery platform to everyday consumers — and that’s without a single data center carrying the load. For Berkshire, which values businesses with durable consumer relationships and pricing power, Apple’s AI trajectory only strengthens the investment thesis.

2. Alphabet (GOOGL) — 6.8% of the Portfolio

Alphabet is the most significant and most discussed new addition to Berkshire’s portfolio. Berkshire first bought Alphabet shares in Q3 2025 under Buffett, acquiring 17.8 million shares worth roughly $5.6 billion at the time. That was already a bold move for a man who had watched Google go public in 2004 and famously passed on it.

But Greg Abel went much further. In Q1 2026, Berkshire nearly tripled its Alphabet position — increasing the stake by 224% to approximately 58 million shares. That position is now worth roughly $23 billion, and Alphabet has jumped to become Berkshire’s fifth-largest holding with a portfolio weighting of 6.8%.

The financial case for Alphabet is compelling. In Q1 2026, Alphabet reported total revenue of $109.9 billion, up 22% year over year. Google Search — the core business that Wall Street had worried AI chatbots might erode — generated a record $60.4 billion in Q1 revenue, a 19% increase and the fourth consecutive quarter of accelerating growth. Far from being disrupted by AI, Google is using it to its advantage through features like AI Overviews and the newer AI Mode, which have actually increased overall search engagement.

Google Cloud is the real growth engine. Cloud revenue hit $20.1 billion in Q1, up an extraordinary 63% year over year, with a backlog of $460 billion indicating the pipeline is full for years to come. Alphabet also owns Waymo, the autonomous vehicle unit that now operates commercial robotaxi services and is widely considered the most advanced self-driving platform in the world.

Crucially, Alphabet is cheap by Magnificent Seven standards. It trades at roughly 17 times trailing earnings with a 36% return on equity — the kind of valuation that makes Buffett-style value investors pay attention. Abel’s massive position increase isn’t just a statement about AI. It’s a statement that Berkshire sees Alphabet as a deeply undervalued business hiding in plain sight.

3. Coca-Cola (KO) — 9.9% of the Portfolio

Coca-Cola is Berkshire’s oldest and most sentimental holding. Buffett acquired 400 million shares between 1988 and 1994 for a total of $1.3 billion. He has never sold a single share. That position is now worth $32.7 billion, and it generated $816 million in dividend income for Berkshire last year alone — an annual return of over 63% on his original cost basis.

Coca-Cola’s AI story is less obvious than Apple’s or Alphabet’s, but it’s real. The company has committed to spending $1.1 billion on Microsoft’s Azure cloud platform over five years, deploying AI tools across its manufacturing, supply chain, and marketing operations. Coca-Cola has used Azure OpenAI to craft marketing campaigns, and it used AI models to design the Y3000 product line — a forward-looking beverage series developed by running consumer preference data through AI systems to predict future flavor trends.

These applications are less flashy than autonomous vehicles or AI search, but they directly protect Coca-Cola’s margins and competitive position — which is exactly why Berkshire holds it. The dividend alone justifies the position.

What Greg Abel Changed in Q1 2026 — and Why It Matters

The Q1 2026 13F filing was a clear signal that Greg Abel is not simply maintaining Buffett’s portfolio. He is actively reshaping it. The key changes tell a story:

What he sold: Visa, Mastercard, Amazon, UnitedHealth, Domino’s, and 11 other positions. These were solid businesses, but Abel appears to have concluded that their valuation ceilings had been reached or that they no longer fit the concentrated, conviction-driven portfolio he wants to run. Notably, Visa and Mastercard — long considered nearly perfect businesses by value investors — were both exited entirely.

What he bought: Alphabet (tripled), Delta Air Lines (returning to airlines for the first time since Buffett’s famous 2020 exit), and a handful of smaller additions. The message is clear: Abel wants fewer positions held with greater conviction.

The cash position: Despite all the buying and selling, Berkshire’s cash pile remains extraordinary. As of March 31, 2026, Berkshire held $397.4 billion in cash, cash equivalents, and short-term Treasuries. This is an almost incomprehensible level of dry powder — suggesting Abel is patient and waiting for a larger opportunity that hasn’t yet materialized.

What This Means for Individual Investors

Berkshire’s Q1 2026 moves are worth studying carefully, but they shouldn’t be copied blindly. A few observations worth keeping in mind:

The concentration in Apple, Alphabet, and Coca-Cola reflects Berkshire’s specific investment criteria — durable businesses, strong cash flows, proven management teams, and reasonable valuations. These aren’t momentum trades or speculative AI bets. They are businesses using AI to strengthen existing competitive moats.

Abel’s exit from Amazon is particularly interesting given Amazon’s dominant position in AI infrastructure through AWS. His apparent preference for Alphabet over Amazon reflects a specific view — that Alphabet’s advertising profitability is structurally superior to Amazon’s e-commerce margins, and that Google Cloud’s growth trajectory is compelling at the current valuation.

The $397 billion cash position is perhaps the most important data point of all. Berkshire is telling the market it is not seeing enough value to deploy aggressively at current prices — except in Alphabet, where it sees exceptional value. That selectivity is a lesson in itself.

Bottom Line: The Oracle of Omaha’s Legacy Meets the AI Era

Warren Buffett spent 60 years building one of the greatest investment track records in history by ignoring trends and focusing on businesses with enduring competitive advantages. The irony is that this discipline led Berkshire directly into the AI era — because the companies with the most durable AI advantages (Apple’s device ecosystem, Google’s search monopoly, Coca-Cola’s brand) are exactly the kind of businesses Buffett has always valued.

Greg Abel is now extending that philosophy with more speed and more willingness to lean into technology. The Q1 2026 portfolio — leaner, more concentrated, and significantly more AI-exposed — looks like Berkshire for the next 30 years.

For investors, the takeaway is simple: the smartest long-term money in the world isn’t chasing AI startups or GPU manufacturers. It’s buying the companies that will use AI to compound their existing advantages for decades. That’s a playbook any investor can learn from.
