Three of four big AI spenders now invest more than their operations earn in cash

Three of the four largest US cloud and AI spenders paid more for property and equipment in the third quarter than their operations produced in cash, according to the quarterly results of Alphabet, Amazon and Meta. Only Microsoft stayed well inside its operating cash flow.

What happened

Each company reported results for the quarter ended September 30, 2026: Meta on October 21, Microsoft and Alphabet on October 28 and Amazon on October 29. Taking the cash flow statement in each release, the combined purchases of property and equipment of Microsoft (Nasdaq: MSFT), Alphabet (Nasdaq: GOOGL), Amazon (Nasdaq: AMZN) and Meta Platforms (Nasdaq: META) were $201.9 billion (computed), against combined net cash from operating activities of $175.5 billion (computed). A year earlier the same four spent $97.3 billion (computed) against $159.0 billion of operating cash flow (computed).

That is a swing from spending equal to 61.2% of operating cash flow to 115.1% (both computed). Purchases of property and equipment rose 2.08 times (computed) while operating cash flow grew 10.4% (computed).

The companies differ widely. Amazon bought $77.3 billion of property and equipment in the quarter, against $42.4 billion of operating cash flow. Alphabet spent $51.4 billion against $42.3 billion. Meta spent $33.9 billion against $32.8 billion, and when principal payments on finance leases are added, as Meta does in its own measure, its capital expenditures were $34.91 billion and free cash flow was negative $2.12 billion. Microsoft spent $39.4 billion against $58.0 billion of cash from operations.

The numbers behind it

The table shows, in millions of dollars, the cash flow lines of the third quarter of 2026 and the third quarter of 2025 as each company reported them. "Gap" is operating cash flow minus purchases of property and equipment, computed here; it is not any company's own free cash flow figure, and Amazon's purchases are shown before $1,381 million of proceeds from equipment sales and incentives.

Company	Operating cash flow, Q3 2026	Purchases of property and equipment, Q3 2026	Gap, Q3 2026	Gap, Q3 2025
Microsoft	58,000	39,367	+18,633	+25,663
Alphabet	42,290	51,355	-9,065	+24,461
Amazon	42,422	77,259	-34,837	+430
Meta	32,786	33,942	-1,156	+11,170

Spending grew by a similar factor everywhere: 2.03 times at Microsoft, 2.14 times at Alphabet, 2.20 times at Amazon and 1.80 times at Meta (all computed). What differed was the cash coming in. Microsoft's operating cash flow rose 28.7% from $45.1 billion, Amazon's rose 19.4%, and Meta's rose 9.3%. Alphabet's fell 12.6% to $42.3 billion from $48.4 billion (all computed).

Why it matters

Amazon's release states the same pattern over a longer period. Operating cash flow rose 29% to $168.3 billion over the 12 months through September, but free cash flow fell to an outflow of $42.4 billion, which the company said was "driven primarily by a year-over-year increase of $94.8 billion in purchases of property and equipment, net of proceeds from sales and incentives." The company said that increase "primarily reflects investments in artificial intelligence."

The spenders also report the revenue the equipment is meant to serve. AWS sales rose 39% to $46.0 billion, and Amazon President and Chief Executive Andy Jassy said in the release that the company projects "revenue growth rates of over 40% both in 2027 and in 2028" for AWS. Google Cloud revenue rose 103% to $30.7 billion, as FinanceInTime reported. Microsoft said Microsoft Cloud revenue was $63.9 billion, with growth accelerating to 30%.

The releases do not say how much of the equipment bought in the quarter is already earning revenue, or how long it will take to do so. That question is outside what the figures can show.

How the gap was funded

The cash flow statements show where the money came from when operations did not cover the spending.

Amazon received $48.1 billion from long-term debt in the third quarter, against none in the third quarter of 2025. Its long-term debt on the balance sheet stood at $173.1 billion on September 30, up from $65.6 billion on December 31, 2025. Its cash and cash equivalents fell to $55.8 billion from $86.8 billion over the same nine months.

Alphabet took in $29.0 billion from debt, net of costs, and $12.4 billion from issuing common stock, compared with $6.6 billion of debt and no stock issuance in the third quarter of 2025. It bought back no stock in the quarter, compared with $11.5 billion a year earlier. Its long-term debt rose to $125.1 billion from $46.5 billion at the end of 2025.

Meta raised no debt in the quarter, but its cash flow statement shows $24.9 billion of net long-term debt proceeds in the first nine months of 2026, and it repurchased no Class A stock in either the quarter or the nine months, against $26.2 billion in the first nine months of 2025. Microsoft repurchased $4.4 billion of stock in its quarter, down from $5.7 billion, and repaid $4.9 billion of debt.

Meta also turned to equity after the quarter closed. In a pricing term sheet filed with the Securities and Exchange Commission, it increased its common stock offering to $25.0 billion, or 40,000,000 shares at $625.00, and expected net proceeds of approximately $24.9 billion when forward sale agreements settle, on or before November 19, 2027. A concurrent offering of mandatory convertible preferred stock was expected to bring in approximately $12.5 billion, as FinanceInTime reported. Those amounts are not in the third-quarter cash flow statement.

What to watch

Meta guided 2026 capital expenditures, including principal payments on finance leases, to $135-145 billion, narrowed from $130-145 billion. Amazon said it continues to expect 2026 cash capital expenditures of approximately $220 billion. Meta said that for 2027 it expects "to continue investing aggressively." Each company's fourth-quarter report will show whether full-year spending lands inside those ranges.

If operating cash flow keeps growing more slowly than purchases of equipment, the gap would have to be covered again by borrowing, share sales or cash on hand. If cloud revenue keeps growing at the rates reported, operating cash flow would be expected to close part of that gap. Both outcomes depend on revenue the releases do not forecast.

Our view

Our view is that the third quarter marks a change in who pays for the AI build-out. A year ago, all four companies financed it from operations. In the third quarter of 2026, three of them financed part of it with debt, stock or cash reserves, and Alphabet and Meta bought back no stock in the quarter, according to the cash flow statements. We read that as a sign that spending decisions are now being made against a funding constraint, not only against demand.

The threat is that spending runs ahead of revenue. Amazon's $42.4 billion trailing outflow and its $173.1 billion of long-term debt show how fast that can build, and a slowdown in cloud growth would arrive while the fixed costs of the equipment are rising. The opportunity is that the revenue is visible: AWS is growing 39% and Google Cloud 103%, and Microsoft shows that a company can double its equipment purchases and still produce $18.6 billion more cash than it spends (computed).

We expect at least one of the three companies with a gap to report spending above operating cash flow again in the fourth quarter if spending stays near the third-quarter pace, and we expect Microsoft to remain cash-positive on this measure. These are forecasts, and they would be wrong if cloud revenue growth accelerates enough to lift operating cash flow faster than spending, or if the companies cut their plans. We would also watch what the filings do not show: the share of new capacity already sold to customers and the useful life assumed for the equipment.
