Investors favor Microsoft's AI spend as Azure grows 43%, Meta slides 8%

On July 30, Microsoft and Meta delivered sharply different AI investment signals. Microsoft shares surged 15.5% after the company reported $41 billion in quarterly capital expenditures alongside Azure revenue growth of 43%, with full-year Azure revenue exceeding $100 billion for the first time. The company also disclosed more than 30 million paid Microsoft 365 Copilot seats, with net additions more than doubling quarter over quarter, and a commercial remaining performance obligation of $678 billion — up 84% year over year — signaling contracted multiyear demand. Investors see a direct line from infrastructure spending to cloud consumption and software subscriptions, even as Microsoft's free cash flow dipped to $19.6 billion and gross margins fell due to AI infrastructure costs and an Azure-heavy sales mix.

Meta's results painted a murkier picture. The company raised its 2026 capital-expenditure forecast to between $130 billion and $145 billion, but quarterly free cash flow plummeted to $784 million from $8.55 billion a year earlier. While Meta's core advertising business performed well — revenue up 28% to $60.8 billion, ad impressions up 14%, and prices up 12% — total costs and expenses jumped 55%, and operating income fell 8%. Meta does not break out AI-attributable revenue, making it difficult for investors to distinguish AI-driven gains from broader advertising trends. The company argues its infrastructure will power larger models and future enterprise products, but with no clear monetization timeline and rising expenses, the market is rewarding Microsoft's more visible AI return on investment. For IT leaders, the takeaway is that workload-level controls and measurable operational results are essential before scaling AI commitments.
