AI boom: Big Tech capital expenditures now seen topping $1 trillion in 2027

Wall Street analysts now project Big Tech hyperscalers' AI capex to exceed $1 trillion in 2027, up from $800-900B in 2026, driven by surging cloud demand and backlogs at Alphabet, Amazon, Meta, and Microsoft. While capex hikes signal robust AI infrastructure buildout, they are pressuring free cash flow for some firms. Chipmakers and data center providers stand to benefit immensely from this escalation.

Why it matters

This unprecedented spending frenzy confirms the AI arms race is accelerating, but raises questions on ROI and infrastructure bottlenecks.
