Just spotted something interesting in the market that might be flying under most people's radar right now. While everyone's been obsessing over Nvidia's insane 1,330% run over the past five years, there's another tech giant that could actually be sitting on way more upside than people realize.

Amazon's been the quiet underperformer in the Magnificent Seven club. Up 44% over five years sounds solid until you realize the S&P 500 basically matched that with an 80% gain. Even Microsoft kept pace better. But here's the thing - I think the market's completely sleeping on what's about to happen with Amazon's core business.

Most people focus on AWS when they talk about artificial intelligence stocks to buy, and yeah, the cloud business is already benefiting from AI demand. But the real opportunity? It's in e-commerce, and it's massive. Amazon's online retail operation is still printing money, but it's burdened by razor-thin margins because, well, shipping physical goods is expensive. That's where AI and robotics come in.

The company's already investing heavily in warehouse automation and autonomous delivery tech. When those efficiencies actually start flowing through the P&L, margins could expand meaningfully. We're talking about the world's largest company by revenue - $716.9 billion last year - suddenly becoming way more profitable. AWS alone threw off $45.6 billion in operating income on just 18% of total revenue. Imagine what happens when e-commerce margins improve even modestly.

This is exactly the kind of artificial intelligence opportunity that creates real wealth. The infrastructure's being built now, but the margin expansion hasn't shown up yet in the stock price. When it does, analysts are talking about a potential 74% surge that could push Amazon into that exclusive $4 trillion club alongside Nvidia.

Looking at artificial intelligence stocks to buy right now, most people are still chasing yesterday's winners. But sometimes the best opportunities are hiding in plain sight in companies that look boring on the surface. Amazon's margin story could be the sleeper play that catches everyone off guard over the next few years. Worth keeping on your radar if you're thinking about where AI is actually going to drive real earnings growth.
