All data is extracted from SEC EDGAR 10-Q (quarterly) and 10-K (annual) filings of Amazon, Microsoft, Alphabet, Meta, and Oracle from Q1 2022 through Q4 2025. We parse the structured XBRL tags rather than relying on company-reported aggregate figures, since companies define “capital expenditure” differently on their earnings calls. For example, Microsoft includes finance lease ROU and accrued-but-unpaid PP&E, Meta includes finance lease principal payments instead of ROU, while Alphabet and Oracle report cash PP&E only.
Fiscal year alignment: Microsoft (fiscal year ending June) and Oracle (fiscal year ending May) report on non-calendar fiscal years. Microsoft fiscal quarters map directly to calendar quarters, while we map Oracle quarters to the calendar quarter with the most overlap (e.g., Oracle FY26Q2, Sep-Nov 2025, maps to CY2025 Q4).
Quarterly derivation: SEC filings may tag standalone 3-month values, year-to-date values, or both. Our extraction logic tries the standalone period first; if unavailable, it derives the quarter by subtracting the prior cumulative from the YTD figure. Q4 values are derived as the 10-K annual total minus the sum of Q1–Q3.
Cash PP&E: Microsoft, Alphabet, Meta and Oracle directly tag us-gaap:PaymentsToAcquirePropertyPlantAndEquipment.
Amazon uses the tag us-gaap:PaymentsToAcquireProductiveAssets.
This component is available for all companies and all periods.
New finance leases: Microsoft, Amazon and Alphabet directly tag us-gaap:RightOfUseAssetObtainedInExchangeForFinanceLeaseLiability. However, prior to 2024, Alphabet did not use this tag; their 2023 10-K filing noted that “finance lease costs were not material for the years ended December 31, 2022 and 2023.” For Meta, we infer new leases from changes in us-gaap:FinanceLeaseRightOfUseAssetBeforeAccumulatedAmortization. For Oracle, we reconstruct new leases as us-gaap:FinanceLeaseRightOfUseAsset (instant) plus us-gaap:FinanceLeaseRightOfUseAssetAmortization (duration).
The claim that capital expenditure growth is driven by AI infrastructure is broadly supported by company earnings calls and reflects their phrasing choices (Microsoft, Meta, Alphabet, Amazon). The exact portion going into AI infrastructure is not provided.
