What the Data Shows
Microsoft, Alphabet, Amazon and Meta are compared on annual capex from FY2021 through FY2025. The series uses company filing metrics in US$ billions and does not use a revenue denominator. Meta and Alphabet had the largest 2021-to-2025 capex multiples, at about four times their FY2021 levels. The four-company total rose from about US$120B in FY2021 to about US$357B in FY2025, while capex definitions differ by issuer.
