Been watching the AI chip market pretty closely, and there's something interesting happening that most people are still sleeping on. Everyone's focused on Nvidia being the obvious play, but I think Alphabet might actually be the better stock to own going into the next phase of this AI cycle.

Here's what caught my attention. Google Cloud just posted 34% revenue growth last quarter with operating margins hitting 24%. That's solid execution. But the real story is their custom TPU chips starting to gain real traction. Anthropic is already planning to use them in 2026, and there's talk of Meta potentially adopting them too. When you've got companies actually switching from Nvidia's standard approach, that signals something's shifting in the competitive landscape.

Then there's the LLM side. Gemini 3.0 came out in November and honestly performed better than what OpenAI and Anthropic were putting out at that time. Enough that Sam Altman apparently called it a code red moment. That's not nothing. And now Apple is licensing it for Siri features starting next spring, paying a billion a year for it. Free money basically, since Apple runs it on their own infrastructure.

But here's what makes Alphabet potentially the best AI stock to watch right now compared to the obvious choices: they're actually using their own innovations across their entire business. Google Search revenue accelerated to 15% growth in Q3, YouTube did 15% as well. Their AI Overviews feature is driving more search queries at similar monetization rates. That's a compounding advantage you don't get with pure chip plays.

Waymo is another wild card. They did 14 million robotaxi trips in 2025, more than triple the prior year. Management says they're targeting 1 million rides per week by end of 2026 across 20 cities. If that scales the way they're projecting, that's a completely different revenue stream.

Valuation-wise, Alphabet trades under 30x forward earnings. Nvidia's over 40x. When you consider Google's got growth across cloud hardware, software, search, YouTube, and Waymo all happening simultaneously, the risk-reward feels better positioned. Nvidia would need to keep crushing expectations to justify where it's priced, and that's a tough bar when competition is finally showing up.

Nvidia's still a beast, but Alphabet looks like the better positioned best AI stock for 2026 if you're thinking about which company actually has the most arrows in the quiver. Worth digging into if you're building an AI-focused portfolio.
