All figures are extracted from SEC EDGAR 10-Q and 10-K filings of Amazon, Microsoft, Alphabet, Meta and Oracle. These are, respectively, quarterly and annual financial reporting documents required for all public companies in the US. We parse the structured XBRL tags directly rather than company-reported aggregates.

Tags used:

• Operating cash flow: us-gaap:NetCashProvidedByUsedInOperatingActivities
• Cash capex: us-gaap:PaymentsToAcquirePropertyPlantAndEquipment (except for Amazon, for which we use us-gaap:PaymentsToAcquireProductiveAssets)
• Operating income: us-gaap:OperatingIncomeLoss (for commentary on continued profitability)

We use cash capex (cash payments for property and equipment) rather than a previously used broader measure that adds new finance leases, because this analysis compares cash out against cash in rather than added capacity. A finance lease commits a company to future payments but involves little cash at signing.

Quarter alignment: Company fiscal quarters fully coincide with calendar quarters except for Oracle. We map Oracle fiscal quarters onto the calendar quarter with which they have the most overlap.

We fit an exponential growth model (ordinary least squares on log-transformed quarterly data) from Q2 2023 through Q1 2026, starting with the release of GPT-4. In aggregate, operating cash flow is growing about 23% per year and cash capex about 70% per year; these trends cross around the third quarter of 2026, when aggregate free cash flow reaches zero.

The crossover date differs by company. On current trends, Oracle has already crossed (capex exceeds operating cash flow), Amazon is crossing around now, Alphabet around 2027 Q1, Meta around 2027 Q3, and Microsoft around 2028 Q3.

If capex exceeds operating cash flow and these companies wish to continue increasing capex, they will need to finance this capex through other means. This could include spending down cash assets, borrowing, or raising funds by issuing new equity.

All five hyperscalers remain profitable and increasingly so. While cash capex is paid upfront, it counts against profits gradually in the form of depreciation over the life cycle of the asset.

• The crossover is sensitive to the fit window — starting the operating-cash-flow fit anywhere from Q1 2022 to Q2 2023 moves the aggregate crossover between roughly Q2 and Q4 2026.
• Operating cash flow is seasonal (e.g. Amazon collects heavily in Q4) and a seasonally adjusted variant delays the aggregate crossover by about a quarter.
• The trend extensions are simple extrapolations of the existing trends, not all-things-considered forecasts. In particular, we do not directly model how the surge in AI-related capex will affect hyperscalers’ future operating cash flow, and whether or not the ROI on AI capex is high enough to increase the growth rate in operating cash.
