Big Tech Earnings Week: Microsoft, Alphabet and Amazon Report as the Fed Decides on Rates

This is the week that tests the AI trade. Microsoft and Alphabet report earnings after the closing bell on Wednesday, October 28, followed by Amazon on Thursday. On the same Wednesday, the Federal Reserve announces its rate decision, with traders pricing about a 90 percent chance rates stay at 3.75 to 4.00 percent. Markets, monetary policy, and the biggest AI spending spree in history all land in the same 48 hours.

The big tech earnings week matters because it is the first real report card on a question that has hung over markets all year: is record AI spending paying off, or is it a very expensive bet that has not yet come due?

Big tech earnings week: the spending numbers are staggering

Microsoft expects capital spending above $50 billion. Alphabet's 2026 capex guidance sits at $195 to $205 billion. Amazon's forecast is about $220 billion. Those are not typos, and they are not annual budgets for small countries by accident. Building AI infrastructure at this scale means data centers, chips, power contracts, and networking, all paid for years before the revenue fully arrives.

That timing gap is the whole debate. Spending is certain and immediate. Returns are projected and gradual. Every quarter, earnings reports narrow that gap a little, or widen it. This week narrows or widens it for three of the biggest spenders at once.

The cloud numbers to watch

Ahead of the reports, the cloud growth figures being cited are striking: Azure up 42 percent, Google Cloud up 82 percent, AWS up 37 percent. If those growth rates hold in the actual reports, the AI spending story looks like an investment with returns. If they slow meaningfully, expect the market to ask harder questions about how long this pace of spending can continue.

Cloud is the right place to look, because it is where AI spending turns into revenue most directly. Companies rent AI capacity, and that rent shows up in cloud growth. A cloud slowdown would not prove AI is a bubble, but it would prove the payback is slower than the spending, which is a different and more uncomfortable conversation.

The options market is pricing a move of roughly plus or minus 7.7 percent across the week for these names. That is a big expected swing, and it tells you how uncertain even professional traders are about what these reports will show.

The Fed in the same week

The Federal Reserve's decision lands Wednesday, the same day as the Microsoft and Alphabet reports. A steady rate decision at 3.75 to 4.00 percent is the expected outcome, but the statement and press conference matter as much as the number. Markets will read every word for hints about the path ahead, because rates set the price of the borrowing that funds data center construction.

High spending plus high rates is a harder combination than high spending plus low rates. If the Fed signals patience, the spending story gets easier to fund. If it signals concern, the same spending looks more expensive. The earnings and the rate decision do not just share a week. They interact.

What this week is really about

Strip away the tickers, and this week asks one question three times: can the companies spending the most on AI show that the spending is already producing growth? Microsoft, Alphabet, and Amazon will each answer differently, because their businesses differ. But the market will hear one combined answer, and it will price that answer into every AI-related stock.

That is why this week feels bigger than a normal earnings week. It is not just three companies reporting. It is a referendum on the largest capital expenditure cycle in tech history, held in the same week as a central bank decision. Whatever the outcome, the AI trade will look different on Friday than it did on Monday. The only question is which direction, and by how much.

Related context: the SoftBank Allied Universal talks and the Schneider Electric PTC acquisition show the same capital cycle playing out in deals, not just earnings, while the AWS capacity sellout explains why the spending cannot easily pause even if markets wobble.
