NVIDIA's numbers look great on paper - strong profits, fat margins, and a grip on the AI chip market that nobody else can match.

And yet the stock just slid 21% from its November peak to $166.21 - putting it squarely in bear market territory.

That's the kind of gap between business performance and stock price that should make investors pay attention. Not because something is broken at NVIDIA, but because the market is starting to ask a harder question: how long can this last?

The $650 Billion Question

Here's the backdrop. Alphabet, Amazon, Meta, and Microsoft plan to pour roughly $650 billion into AI infrastructure this year. That's mostly data centers, chips, and servers - the exact stuff NVIDIA sells.

Sounds like a goldmine for NVIDIA, right?

Investors aren't so sure. That figure is roughly 60% higher than what those same companies spent last year. And it dwarfs the combined budgets of 21 other major US companies across autos, defense, and energy.

Each of those four tech firms is expected to blow past its combined spending from the previous three years in a single calendar year. The scale is hard to wrap your head around.

The worry isn't that the money is being spent. It's that nobody knows when - or if - that spending turns into profit. Building data centers is one thing. Generating enough revenue from AI tools to justify the bill is something else entirely.

The Whole Group Is Hurting

NVIDIA isn't falling alone. The so-called Magnificent Seven - the group of giant tech stocks that powered the market higher for the past few years - are all getting hit.

Microsoft has shed roughly 34% from its highs. Meta is off around 29%. Amazon, Apple, and Tesla have all lost double-digit percentages as well.

The pattern is the same everywhere: strong businesses, big revenue, growing earnings - and a market that's lost confidence in the growth story holding it all together. Profit growth for this group is expected to slow to about 18% in 2026 - the weakest pace since 2022 and barely ahead of the rest of the S&P 500.

That gap used to be massive. Now it's almost gone. And when the premium shrinks, so does the reason to pay up for these stocks.

What to Watch

NVIDIA's next earnings report lands in late May. Investors will be watching two things closely: whether data center revenue keeps growing, and whether the company signals any change in the pace of orders from its biggest customers.

If those four tech giants start pulling back on spending - or even hinting at it - NVIDIA's stock has room to fall further. But if demand holds, today's price could look like a bargain down the road.

Right now, the market is betting on doubt. NVIDIA's job is to prove it wrong.
