Top Tech Firms Plan $650B AI Capital Expenditure in 2026, Intensifying War and Testing Investor Patience

Alphabet (GOOGL-US), Microsoft (MSFT-US), Amazon (AMZN-US), and Meta (META-US) are planning combined capital expenditures of approximately $650 billion in 2026, primarily for new and upgraded data centers and AI-acceleration infrastructure including AI chips, cabling, and backup generators. Meta reported 2025 capital spending of $13.5 billion, up 87%. Microsoft’s second-quarter spending rose 66% year-over-year to about $10.5 billion, with full-year guidance near $10.5 billion. Alphabet plans up to $18.5 billion, and Amazon’s 2026 plan tops $20 billion. Analysts at DA Davidson note the “next winner-takes-most” dynamic in AI compute, with no clear frontrunner. Constraints include shortages of electrical workers, concrete, and TSMC’s (2330-TW; TSM-US) NVIDIA chips. While strong cash positions support the spending, the pace raises concerns about timing of returns and investor patience as the AI bubble reemerges. Jefferies analyst Brent Thill said investors are pausing at tech stocks amid heightened caution.
