Meta and Microsoft enter earnings with $300 billion in AI capex and skeptical investors

· by Pondero Newsdesk

The short version

Alphabet lost more than 7% the day after raising its 2026 capex target. Meta reports July 29 with up to $145 billion in planned AI spending; Microsoft carries roughly $190 billion. Investors want to know when the returns arrive.

Meta and Microsoft enter earnings with $300 billion in AI capex and skeptical investors

Alphabet lost more than 7% on July 24 after the company raised its 2026 capital expenditure target to as much as $205 billion and reported that free cash flow turned negative in Q2 for the first time since its 2004 IPO. Meta Platforms and Microsoft report their own Q2 results on July 29 carrying combined AI infrastructure commitments of more than $300 billion for this year alone, into the same skeptical market.

What

Microsoft and Meta Platforms both report after market close on July 29. Apple and Amazon follow on July 30. Together, all four companies are projected to spend approximately $724 billion on capital infrastructure in 2026, per analyst estimates compiled by Bloomberg and cited in Fortune.

The market backdrop is punishing. Microsoft stock had already fallen 21% in 2026 before Alphabet's report, making it the second-weakest performer in the Magnificent Seven. Meta shares were down 9.8% for the year. The Mag Seven index tumbled another 4.8% on July 24 alone, per Fortune, its worst single day since the April 2025 tariff selloff.

Part of Meta's pressure predates earnings. At an internal town hall on July 2, CEO Mark Zuckerberg told employees that AI agent development had not accelerated in the way the company expected, per a recording obtained by Reuters and reported by TechCrunch. Meta has guided full-year capital spending to as much as $145 billion. That admission, paired with that spending commitment, is the central contradiction investors want resolved on the earnings call.

For Microsoft, the central question is Azure growth. Analysts expected 39 to 40 percent constant-currency growth for the quarter. Azure is the primary gauge of whether Microsoft's AI compute spending is generating revenue at scale rather than accumulating as sunk infrastructure cost.

Why it matters

AI tool operators who build on Azure or deploy products using Meta's Llama models have a direct stake in both calls. A miss on Azure growth signals that enterprise AI adoption is not converting at the rate Microsoft projected, which could slow the pace of capacity expansion and affect future pricing. A credible Zuckerberg update on agent timelines would, by contrast, give more confidence to teams building on the Llama ecosystem.

Alphabet's Q2 broke a three-year consensus: cloud revenue grew 82% and the stock still fell, the first time capex expansion failed to read as a growth signal. Meta and Microsoft now face the same test. Fortune's reporting on analyst consensus heading into the calls identifies three signals: margins, free cash flow, and explicit AI revenue line items.

What to watch

Three things could move the tape on July 29: whether Azure reports at or above 40% constant-currency growth, whether Zuckerberg offers a concrete revised timeline for agent capability, and whether either company breaks out AI-attributed revenue as a distinct line item for the first time. Apple reports on July 30 in what is expected to be CEO Tim Cook's final earnings call before John Ternus takes over on September 1.
