Q3 Tech Earnings Preview: All Eyes on AI Spending

A few years ago, info tech firms often faced concerns on Wall Street about spending too much. Now, it's the opposite. As major names like Microsoft (MSFT), Apple (AAPL), and IBM (IBM) line up to report, investors appear to want heavy spending to roll on, keeping the AI euphoria bubbling. At the same time, the tech sector faces new tariff concerns ahead of third-quarter earnings, leaving investors wondering how a potential longer-term spat with China might hurt businesses.

As the heaviest hitters step up to the earnings plate, many investors will focus more closely than ever on capital expenditures, seeking possible cracks in the AI armor that might hint at a spending top. Debate swirls about whether AI is in its "second inning" or "seventh-inning stretch." Currently, AI is on the pitcher's mound hurling new products at the tech sector, which has swung at every pitch for years.

Earnings season could help investors learn if the tech batter is about to call time out or even getting ready to step out of the box, which seems unlikely given all the recent AI deal-making. And in this case, "tech" means the traditional non-chipmaker tech stocks caught up in the AI frenzy. This includes Amazon (AMZN), Tesla (TSLA), Alphabet (GOOGL), and Meta Platforms (META), which aren't in the S&P 500 tech sector but have a huge impact with their cloud and EV offerings.

"We're still in the mode where we want to see capital spending go up because it signals to the market that we're still in the early innings on the AI-investment binge," said Nathan Peterson, director of derivatives analysis at the Schwab Center for Financial Research. "So, if there's any stutter, that could give investors pause."

As earnings approach, keep in mind what the mega-caps' forecast from a spending perspective was last time they reported. Any material change, especially downward, might hurt the sector or even pull the entire market lower.

Tracking spending plans

Here's what the largest "hyperscaler" cloud companies said about capital spending last quarter:

  • Microsoft: Capital expenditures will grow in the new fiscal year but more slowly than in the 2025 fiscal year that ended in June.
  • Alphabet: Capital expenditures for 2025 will be $85 billion, up $10 billion from February, due to "strong and growing demand for our Cloud products and services."
  • Meta Platforms: 2025 capital expenditures will come in between $66 billion and $72 billion, above the low end of the company's previous estimate of between $64 billion and $72 billion.
  • Amazon: The company plans to spend as much as $100 billion this year on AI as it builds data centers and software.

Keep that as a cheat sheet when these companies report October 29 and 30. Apple, which has been slower on the AI spending path, reports October 30.

The markets are also sensitive to valuations in tech, which are near the high end of the 10-year range for most of the biggest mega-cap firms. This likely won't trouble investors if companies can continue to grow revenue double-digits and surpass guidance expectations. But mega-caps face tougher comparisons to year-ago results each quarter, making it more challenging to deliver results like Microsoft's 18% year-over-year revenue growth in its last quarter. AI-related demand has driven multiple expansion.
