Analysis: Meta, Alphabet, Microsoft, and Amazon's combined capex hit a record $130B in Q1 and is projected to reach $725B in 2026, up 77% from $410B in 2025 (Financial Times)

The Big Four tech companies are dramatically accelerating infrastructure spending, with combined capex projected to reach $725B in 2026—a 77% increase from 2025—driven primarily by AI investments that are generating substantial returns (Microsoft's AI business alone hit a $37B annual run rate, up 123% YoY). This unprecedented capital deployment signals that technology leaders must prepare for a fundamental shift in IT architecture and vendor economics as AI workloads become central to enterprise operations. CIOs should expect margin compression in the near term, changing pricing models from consumption-based to usage-aligned structures, and pressure to justify IT spending increases despite macro constraints, as cloud infrastructure remains a strategic priority for enterprises pursuing AI capabilities.
