Meta Platforms shares dropped as much as 9.6% in after-hours trading on July 29, 2026, after the company posted second-quarter results that missed profit expectations and raised its AI infrastructure spending guidance for the second time this year, according to CNBC’s earnings coverage. The market reaction highlighted a growing divide among investors over how much capital expenditure Wall Street is willing to tolerate before demanding proof of return.
The Numbers That Spooked Investors
Meta reported earnings per share of $6.18, badly missing the $7.14 consensus analysts had expected. Revenue came in slightly ahead of forecasts at $60.8 billion, with advertising revenue of $59.3 billion topping the $59.07 billion analysts projected. But the figure that dominated the reaction was free cash flow, which collapsed from $8.5 billion in the prior quarter to just $784 million — a decline investors read as direct evidence that AI infrastructure spending is now consuming nearly all the cash the core advertising business generates.
Capex Guidance Keeps Climbing
Compounding the concern, Meta raised its full-year 2026 capital expenditure guidance to a range of $135 billion to $145 billion, up from a previous range of $125 billion to $145 billion — meaning the low end of the range jumped by $10 billion in a single quarter. That increase came without a correspondingly clear signal to investors about near-term revenue payoff from the spending, which analysts say is the central reason the stock fell as sharply as it did, even though the underlying advertising business continued to grow. Analysts on the earnings call pressed executives for a clearer timeline showing when infrastructure investment would translate into measurable advertising or product revenue, a question management addressed only in general terms about long-term AI competitiveness rather than specific financial targets.
A Pattern Across Big Tech Earnings
Meta’s reaction wasn’t an isolated event. Bloomberg described the broader earnings season bluntly as “Big Tech Earnings Slam Into a Market in Revolt Over AI Spending.” Combined, Alphabet, Amazon, Microsoft, and Meta are expected to spend roughly $725 billion on capital expenditures in 2026, up 77% from the prior year’s $410 billion, according to figures reported by Tom’s Hardware. Microsoft and Amazon shares rose after their own reports because investors could point to Azure and AWS revenue growth as tangible proof of monetization; Alphabet, Meta, and Oracle fell because the connection between spending and near-term payoff was less clear.
The Bull Case for Meta’s Spending
Meta executives and some analysts argue the spending is a necessary bet to remain competitive in frontier AI model development and to support AI-driven improvements to its advertising targeting and recommendation systems, which remain the company’s primary revenue engine. From that view, temporary cash flow pressure is the price of staying in a race that Meta cannot afford to lose, given how central AI has become to the core business it already monetizes at scale.
The Bear Case: Show Me the Return
Skeptics counter that raising guidance without a matching increase in visible AI-linked revenue — the way Microsoft and Amazon could point to Azure and AWS growth — leaves Meta vulnerable to a valuation reset if investor patience runs out. Analysts have noted that free cash flow evaporating this quickly, even temporarily, limits Meta’s flexibility for buybacks and other capital returns that had helped support the stock over the past two years.
What’s Next for Meta
Meta’s next earnings report will be closely watched for whether free cash flow stabilizes or continues declining, and whether management provides clearer metrics tying AI infrastructure spending to specific revenue outcomes, such as improved ad conversion rates or new AI-driven products. Until then, Meta is likely to remain one of the more volatile bellwethers in the broader debate over whether Big Tech’s AI capital expenditure surge is a justified investment or an early warning sign of overextension. The next earnings date will carry outsized weight, given that a second consecutive quarter of cash flow deterioration without a clearer revenue link could accelerate the kind of valuation reset that Bank of America and other Wall Street strategists have already warned about across AI-heavy stocks more broadly.
