Hyperscaler Capex as a Percent of Operating Cash Flow
Quarterly companywide cash purchases of property and equipment divided by operating cash flow at Microsoft, Alphabet, Amazon, and Meta. The ratio shows how intensively current cash generation is funding infrastructure capacity, including—but not limited to—AI, and can swing with working-capital timing.

In 2026-06-30, Amazon spent 119.4%% of quarterly operating cash flow on cash purchases of property and equipment.
Methodology
For every company and quarter, the plotted value is (quarter-only cash capital expenditures / quarter-only net cash provided by operating activities) * 100. Both inputs are in millions of U.S. dollars, so the units cancel. The CSV stores the percentage to six decimal places and identifies the exact numerator and denominator in every point note.
The capex definition is held constant across companies: gross cash paid to purchase or add property and equipment as presented in investing activities. For Microsoft this is 'Additions to property and equipment'; for Alphabet and Meta it is 'Purchases of property and equipment'; and for Amazon it is the same reported cash-flow line, tagged in XBRL as PaymentsToAcquireProductiveAssets. The measure excludes acquisitions, marketable securities, non-cash property acquired through finance leases, principal payments on finance leases, and proceeds from property sales. It is therefore cash capex, not each company's broader or non-GAAP capex/free-cash-flow definition.
Quarter-only inputs are derived exactly from reported cumulative values. For calendar-year companies, Q1 is the reported three-month amount; Q2 is six-month YTD minus Q1; Q3 is nine-month YTD minus six-month YTD; and Q4 is the full-year amount minus nine-month YTD. Microsoft has a June fiscal year-end, so the same sequence is applied within its July-June fiscal year: calendar Q3 is Microsoft fiscal Q1, calendar Q4 is fiscal six-month YTD minus fiscal Q1, calendar Q1 is fiscal nine-month YTD minus fiscal six-month YTD, and calendar Q2 is the fiscal-year total minus fiscal nine-month YTD.
The dataset uses reported GAAP cash-flow statement amounts from Forms 10-Q and 10-K, not management capex guidance, analyst estimates, accrual-based additions, or AI-only estimates. Timestamps are calendar quarter-end dates even though Microsoft labels the same periods using its fiscal-year convention.
Ratios can exceed 100% when quarterly cash capex is greater than quarterly operating cash flow. A negative operating-cash-flow denominator would produce a negative ratio and would be explicitly flagged; a denominator with an absolute value below $1 billion would be retained but marked denominator-sensitive rather than suppressed or capped. No included denominator is negative, zero, or below $1 billion. Amazon's Q1 2023 denominator was the lowest at $4.788 billion, so its 296.7% observation is genuine but unusually sensitive to quarter-to-quarter working-capital timing.
This is not a measure of AI capex. The numerator includes all cash purchases of property and equipment disclosed at company level, including data centers, servers, networking, offices, land, logistics assets and other equipment. It is most useful as a comparable financing-intensity measure: how much current operating cash generation is being consumed by cash capital investment.
Frequently asked questions
How is hyperscaler capex as a percent of operating cash flow calculated?
For each company and quarter, divide quarter-only cash purchases of property and equipment by quarter-only net cash provided by operating activities, then multiply by 100. For example, Alphabet's Q2 2026 cash capex was $44.924 billion and operating cash flow was $39.069 billion, producing 44.924 / 39.069 * 100 = 114.986306%.
Why can the ratio be above 100%?
A value above 100% means the company paid more cash for property and equipment during the quarter than it generated from operations during that same quarter. The difference can be funded with cash on hand, investments, debt, asset-sale proceeds or other financing. It is not an error and the chart does not cap the result at 100%.
Does capex mean AI infrastructure spending?
No. These are companywide cash purchases of property and equipment. AI data centers are an important driver in recent periods, but the filings do not provide a complete, consistently defined quarterly AI-only capex series across all four companies. Amazon also includes logistics infrastructure, while all companies can include offices, land and other non-AI assets.
Are finance leases included in capex?
No. To preserve one comparable cash definition, the numerator excludes non-cash property acquired under finance leases and excludes finance-lease principal payments. Some companies include those items in their own supplemental free-cash-flow or capex discussion, so this chart may differ from a company-presented capex figure.
How are quarterly values derived when filings report year-to-date cash flows?
Q2 equals six-month YTD minus Q1, Q3 equals nine-month YTD minus six-month YTD, and Q4 equals the annual total minus nine-month YTD. Q1 is already a three-month amount. The same arithmetic is applied inside Microsoft's July-June fiscal year, then observations are placed on calendar quarter-end dates.
How does the chart handle negative or very small operating cash flow?
It does not replace, cap or take the absolute value of the denominator. A negative denominator would produce a signed negative percentage and be flagged. A denominator below $1 billion in absolute value would be retained and labeled denominator-sensitive because the percentage can become extremely volatile. No observation in the current dataset meets either condition.
Why was Amazon's ratio nearly 297% in Q1 2023?
Amazon reported $14.207 billion of cash property-and-equipment purchases and only $4.788 billion of quarter-only operating cash flow. Working-capital timing can make quarterly operating cash flow volatile, so the resulting 296.7% is mathematically correct but should not be treated as Amazon's stable annual investment rate.
