The hyperscalers report this week — and the AI spending bill comes due
Microsoft, Alphabet and Amazon report this week, and one question matters more than the profit numbers: is the AI spending actually paying off?

The News
The biggest week of the earnings season for artificial intelligence arrives in the next few days — and so far, it is all preview, not results. Microsoft and Alphabet, the parent company of Google, both report after the market closes on Wednesday, October 28, with Amazon following after the close on Thursday, October 29, according to a Reuters preview published October 24. None has reported yet, so every number here is an expectation, not an outcome. The market's focus is narrower than usual: investors are less interested in last quarter's sales than in what executives say about future spending on AI infrastructure, and what return that spending is producing.
The spending figures are enormous. Hyperscaler capital expenditure — capex, the money spent building things like data centers and buying the chips and servers inside them — is expected to reach roughly $800 billion this year, per the Reuters preview. At some point, hundreds of billions in data centers must show up as revenue growth, or investors will ask whether the buildout is running ahead of demand. Capex guidance — the company's own forecast of future spending — is therefore the number to watch, alongside the usual profit figures.
The consensus estimates cited in the preview give the market its yardsticks. For Microsoft, analysts expect earnings per share (EPS) of $4.71 — profit per share — with Azure cloud growth near 45%. Alphabet is expected to report EPS of $2.94, and Amazon EPS of $1.96. EPS is simply total profit divided by the number of shares, and the consensus is the average analyst forecast; the gap between the actual result and the consensus is what moves share prices. Azure's growth rate matters because Microsoft's cloud business is the clearest window into whether corporate customers are actually paying more for AI services, rather than just talking about them.

Why It Matters
Start with why three earnings reports matter to anyone who does not own the stocks. Microsoft, Alphabet and Amazon are building the physical backbone of AI: the data centers, the chips inside them, and the cloud services renting that computing power to everyone else. When they spend, chipmakers, power companies, construction firms and regional economies feel it. When they slow down, the whole AI supply chain feels that too. Their earnings are less like three company reports and more like a health check on the AI boom itself.
The second reason this week matters is the size of the bet. Roughly $800 billion in capex this year is not normal corporate spending; it is a wager, made simultaneously by a handful of companies, that demand for AI computing will keep growing fast enough to justify it. If that wager pays off, the spending looks visionary. If demand grows more slowly than the data centers being built to serve it, the spending looks like overbuilding — the kind of thing that ends with empty buildings and write-downs. That is why guidance matters as much as results: guidance tells investors whether the companies themselves still believe the bet.
The third reason is the yardstick effect. Consensus estimates exist so the market has a shared expectation to judge against, and the three numbers here — Microsoft $4.71, Alphabet $2.94, Amazon $1.96 — will be the scoreboard on Wednesday and Thursday. But EPS alone does not capture the AI story. Azure's growth near 45% is arguably the more important Microsoft figure, because it measures whether customers are paying for AI-powered cloud services at a pace that justifies the data-center buildout. Watch the cloud numbers and the capex guidance first; the EPS headlines second.
Analyst's Take
The verdict is Mixed, because this week can genuinely go either way: the preview contains both a bull case and a bear case. The bull case: Azure growing near 45% would show AI spending by corporate customers is real, durable demand — and if all three guide capex higher while reporting that kind of growth, the AI infrastructure trade has room to run. The bear case: guidance is where disappointments live. If any of the three signals returns on AI investment are arriving more slowly than expected, or trims spending plans, the market will read it as the first crack in the biggest capital-spending boom in tech history.
For readers, the practical move is to watch guidance, not just the headline profit number. A company can beat its EPS estimate and still fall if its capex outlook spooks investors, and can miss slightly and rise if cloud growth accelerates. Keep the three consensus figures — $4.71, $2.94, $1.96 — in mind for Wednesday and Thursday. Until results land, this is a week of expectations, and expectations are exactly what markets punish when they are wrong. Readers' poll: will the hyperscalers' capex guidance beat or disappoint this week?
By The Numbers
FAQ
What is EPS, in plain words?
EPS stands for earnings per share. Take a company's total profit for the quarter, divide it by the number of shares outstanding, and you get the profit earned per share. Analysts publish a consensus estimate — basically the average of their forecasts — and the market compares the actual result against it. Beat the estimate and the stock usually rises; miss it and it usually falls.
What is capex, and why does everyone keep talking about it?
Capex is short for capital expenditure: money a company spends on long-lasting things it builds or buys, like data centers, servers and networking gear. For the hyperscalers, capex is the price tag of the AI race. Investors want to know not just how much they spent, but whether that spending is turning into revenue — the return on the investment.
Why do Microsoft, Alphabet and Amazon report on different days?
Each company sets its own earnings calendar. Microsoft and Alphabet both report after the market closes on Wednesday, October 28, and Amazon follows after the close on Thursday, October 29. Reporting after the close gives investors the evening to digest the numbers before trading resumes the next morning.
