Watch These Five AI Signals Closely This Week

Nvidia CEO Jensen Huang’s insistence this week that he did not “believe we’re in an AI bubble” is all well and good when you’re the man selling the finest shovels for the artificial-intelligence boom. But what of the companies that are expected to turn all that AI building into gold?

Five of the so-called Magnificent Seven — Amazon.com Inc., Alphabet Inc., Meta Platforms Inc., Apple Inc. and Microsoft Corp. — will report earnings this week. Optimism going in could not be higher, with shares of the world’s largest technology companies driving up stocks to records this week in what is largely a story about AI and its promise.

But when it comes to searching for signals on AI’s potential to provide a healthy return, Wall Street has often proved to be fickle, reacting harshly to even the slightest blip. Here are the signals I’m looking for Wednesday and Thursday as the tech giants discuss their performances.

Is AWS improving against Microsoft Azure and Google Cloud?

This month’s 15-hour-long failure affecting vast swaths of Amazon’s cloud client base was deeply embarrassing. Memories, however, are short — and with the problem patched up and operations running smoothly again, investors will now be far more concerned by the broader trajectory of Amazon Web Services, particularly how it’s faring in the AI race. While it is still comfortably the largest cloud provider in the world, its ability to attract AI-specific use cases — training and inference — are in question. Microsoft just sealed a revised pact with OpenAI that will allow it to keep its close relationship and associated cloud income, at least for the next few years. Google Cloud has been picking up big money deals, and its homegrown chips are starting to gain a reputation as an alternative to those made by Nvidia. Amazon is competing on all of these fronts — investors will want indications of how well.

How much is the demand crunch pushing up capital spending?

There’s a reason every new day brings news of a huge deal for data center construction. Demand for computing power is currently outstripping supply. That’s why we’ve seen an explosion in capital expenditures this year that is expected to continue through 2026. The question for this week of earnings, then, is whether those projections are adjusted and by how much.
