Meta, Microsoft, Apple, and Amazon face investor AI spending test in July 29-30 earnings after Alphabet took a 7% hit

The short version

Alphabet's post-earnings selloff last week reset investor tolerance for AI capital spending without visible returns. Three of the four companies behind $724 billion in projected 2026 capex now report alongside Apple.

Alphabet reported last Tuesday that it would raise its 2026 capital expenditures to as much as $205 billion, then watched its shares fall more than 7% in a single session. That happened despite an 82% increase in cloud-computing revenue that beat analyst estimates, per Fortune's July 26 analysis. Microsoft and Meta report on July 29. Apple and Amazon follow on July 30.

What

Alphabet, Microsoft, Amazon, and Meta are collectively projected to spend about $724 billion on capital expenditures in 2026 and nearly $950 billion in 2027, based on Bloomberg analyst estimates cited by Fortune. Microsoft's share of that total is estimated at more than $190 billion for the calendar year. Alphabet's free cash flow turned negative in Q2 for the first time since its 2004 IPO, a fact that weighed on investor sentiment even as cloud revenue surged.

Entering this week, Microsoft shares are down 21% for 2026 and Meta is down 9.8%, per Fortune's market analysis. The Magnificent Seven index fell 4.8% on Thursday after Alphabet's report and now sits down 3.7% for the year. Apple charts a different course. The company partnered with external model providers rather than building large in-house AI infrastructure, and its shares are up 23% in 2026 and 15% in July alone, making it the biggest single points contributor to the S&P 500's 8.3% gain this year.

Why it matters

Alphabet's result made the new investor calculus explicit: revenue growth no longer neutralizes capex growth in the market's eyes. Jason Lemire, chief investment officer at Bold Wealth Partners, told Fortune: "It used to be the more the better, but now it is the less the better."

For AI tool operators, that shift carries a practical edge. Microsoft, Amazon, and Google supply most of the compute and API capacity that AI-native tools depend on. If earnings pressure leads any of the three to slow infrastructure deployment, model availability timelines and cloud capacity commitments are likely to move. Brad Warden, senior portfolio manager at Nomura Asset Management, noted in the Fortune piece that historical valuations had become less relevant: "They look cheap right now, but when you look forward at potential disruption, they are guilty until proven innocent." Microsoft currently trades at 19 times estimated earnings, below its 10-year average of 27 times; Meta is at roughly 14 times against a 10-year average of 20 times.

Meta's exposure differs from Microsoft's. Its AI spending sits primarily in internal model development and recommendation systems rather than cloud services sold externally. The investor question on July 29 is whether that spending is compressing or expanding margins.

What to watch next

On Microsoft's July 29 call, the key signal is Azure AI services revenue growth and any commentary on infrastructure spend pacing. Meta's call the same day will test whether Llama model development and agent infrastructure investments show up in margins. On July 30, Amazon's AWS AI revenue attribution and Apple's explanation of how long a low-capital AI strategy remains viable will close out the week. If any company breaks out AI revenue as a separate reporting line for the first time, that would signal a structural shift in how the sector accounts for this spending cycle.
