Just realized something interesting about Warren Buffett's recent moves that most investors seem to be missing. The Oracle of Omaha is actually betting big on AI, even though everyone thinks he avoids chasing market trends. His track record speaks for itself — if you'd put $1,000 into Berkshire Hathaway when he took over in 1965, you'd be looking at over $50 million today. That's the kind of long-term thinking that separates real investors from the noise.

What caught my attention is that roughly 23% of Berkshire's $317 billion stock portfolio is now tied to three companies that are seriously leveraging artificial intelligence. And these aren't flashy startups — they're established giants quietly transforming their core businesses with AI. This is the kind of move that actually matters.

Let's start with Amazon. It's only 0.7% of the portfolio, but the AI angle is fascinating. Beyond e-commerce, AWS is the real story here. They've got a $200 billion order backlog from customers desperate for data center capacity, and Amazon's spending $125 billion this year to build more infrastructure. They even designed their own AI chips — Trainium2 — that cost 40% less than alternatives when training models. Anthropic's using 500,000 of these chips for Claude. Buffett admits he should've identified this opportunity earlier, but the stock's more than doubled since Berkshire got in, and there's likely more runway ahead.

Then there's Alphabet, which represents 1.7% of the holdings. A lot of people worried that ChatGPT would cannibalize Google Search, but Alphabet moved fast. They integrated AI directly into search with features like AI Overviews and AI Mode, and it's actually working — search revenue is accelerating. Google Cloud is also competing hard with AWS, sitting on a $155 billion backlog and building out their own TPUs as alternatives to Nvidia's chips. The stock's up 62% this year, and Berkshire only recently added to their position in Q3 2025.

But here's where it gets really interesting — Apple is the heavyweight at 20.6% of the portfolio. Buffett and his team poured roughly $38 billion into Apple between 2016 and 2023. They've trimmed the position significantly, selling over 70% of it, but it's still their dominant holding. With 2.35 billion active devices worldwide, Apple is uniquely positioned in consumer AI. They launched Apple Intelligence last year with writing tools, an image generator, and an upgraded Siri. Every device runs on Apple-designed chips optimized for AI, which means better performance and battery efficiency. The new iPhone 17 lineup is apparently driving a stronger upgrade cycle than expected, suggesting there's still real potential here.

What's compelling about these three is that they're not chasing AI hype — they're embedding it into existing, profitable businesses. If you're looking for some of the best AI shares to consider right now, this portfolio tells you something important about how serious money actually approaches the space. These companies have the scale, the capital, and the customer base to dominate as AI evolves. Worth keeping an eye on if you're thinking about your own AI exposure, especially on platforms where you can track these holdings and spot emerging opportunities.
