Warren Buffett's AI Stock Pick: Alphabet (GOOGL) Up 25% - Should You Buy Now? (2026)

Picture this: Warren Buffett, the legendary investor known as the Oracle of Omaha, has just made a bold move into the world of artificial intelligence by investing in Alphabet stock. And get this—it's already soared over 25% since Berkshire Hathaway scooped it up. Could this signal a seismic shift in Buffett's famously cautious approach to tech? Stick around, because this story is just heating up, and you won't want to miss why it might still be a smart time for everyday investors to jump on board.

Let's break it down step by step, keeping things clear and straightforward even if you're new to investing. First off, recall how Buffett's close buddy, Bill Gates, introduced him to ChatGPT back in 2023. After tinkering with the AI chatbot, Buffett was genuinely wowed by its ability to streamline tasks and save precious time for people everywhere. It showcased real technological leaps forward.

That said, Buffett has always steered clear of tech-heavy companies in the past. His conglomerate, Berkshire Hathaway (traded as NYSE: BRK.A and NYSE: BRK.B), hadn't dipped its toes into the generative AI wave since ChatGPT's debut. But here's where it gets interesting—until their latest quarterly report, that is. In their third-quarter Form 13F filing with the SEC, Berkshire revealed a fresh purchase: nothing less than 17.8 million shares of Alphabet (NASDAQ: GOOGL and NASDAQ: GOOG). And despite the stock's impressive climb since then, analysts suggest it could still be a timely opportunity for individual investors to follow suit.

Why is this such a big deal for AI? Alphabet isn't just any company—it's a powerhouse in the tech space that Buffett himself admitted he regretted not buying way back in 2018. Now, it's become Berkshire's 10th-largest U.S. stock holding. Sure, Alphabet's operations are more complex than the straightforward businesses Buffett typically favors, but at its heart, it runs two giants that feel stable: Google Search and YouTube, where millions flock daily for information and entertainment. On top of that, they sell ads on these platforms, and they're expanding in cloud computing by building data centers and renting out computing power to other businesses.

But here's the part most people miss—and it's what likely caught Buffett's eye. Alphabet is a cash-flow dynamo. Over the past 12 months, it's generated a whopping $73.6 billion in free cash flow, fueled mostly by its lucrative advertising and growing cloud services. Even with massive investments in AI, including new data centers, this financial strength shields it from rivals and lets it keep innovating. For beginners, free cash flow is basically the money left after paying for operations and investments—think of it as the company's savings account for future growth.

As Alphabet's cloud business ramps up, it's showing the kind of efficiency gains experts predicted. Its operating margin— a simple way to measure profitability, like how much profit it makes from each dollar of sales—hit 24% in the latest quarter, up from 17% the year before. This boost has helped drive earnings even as AI chatbots challenge the Search business. All told, the stock's forward price-to-earnings (P/E) ratio, which compares the share price to expected future earnings (a key metric for valuing stocks), was under 20 for much of the quarter. It ticked up to over 24 after a favorable court decision in an antitrust case, but that's still a steal for a company whose earnings per share have jumped 35% year over year so far, with more growth on the horizon.

And this is the part that might spark some debate: Is Buffett abandoning his principles by betting on tech? Critics might say yes, arguing he's straying from his value-investing roots. But here's a counterpoint—maybe he's adapting, seeing Alphabet's AI potential as too lucrative to ignore. What do you think? Does this shift change how we view the Oracle's timeless strategies?

Fast-forward to recent developments, and Alphabet's stock has been on a rocket ride since September. First, that court ruling allowed them to keep key default search deals with fewer restrictions, solidifying Google's dominance. Then, their third-quarter earnings blew expectations out of the water with strong revenue and profits. A massive 82% jump in cloud backlog—a measure of future sales commitments—gave confidence in their hefty spending plans. Management even raised their capital expenditure budget to $91-93 billion this year, up from $75 billion, pouring money into AI infrastructure.

The stock got another lift from Berkshire's investment reveal, and it kept soaring after the positive buzz around their Gemini 3 AI model. This version outperformed rivals from Anthropic and OpenAI on most tests, crucial for powering AI features in search and licensing tools to developers. Plus, reports suggest Meta Platforms might partner with Alphabet, using their Tensor Processing Units (specialized chips for AI) in data centers and renting capacity via Google Cloud. Add in a similar deal with Anthropic to handle workloads starting next year, and with Meta and Anthropic's huge AI budgets, these could skyrocket Google Cloud's backlog.

All this hype has pushed Alphabet's forward P/E from under 20 a few months ago to nearly 29 now. For a company with such explosive earnings growth, that still feels like a bargain. But let's not sugarcoat the challenges—depreciation (the accounting way of spreading out the cost of big assets like data centers over time) will start hitting their profits in the coming years. Yet, the scaling benefits of cloud growth and advertising's high margins should balance it out. At around 30 times expected earnings, it's arguably still fair value, given the momentum.
