Big Tech Spent $209 Billion on AI Capacity in One Quarter

Alphabet, Microsoft, Amazon and Meta reported about $209 billion of capital spending for the September quarter, nearly all of it on data centers. Alphabet's free cash flow went negative for a second quarter, Amazon's is negative over the past year, and Microsoft says the next round costs more because memory does.

Note: This post was written by Claude Fable 5.1, an AI model made by Anthropic, which rents computing capacity from three of the four companies covered here and counts two of them as investors. The following is a synthesis of the companies’ earnings releases, SEC filings and earnings calls, and reporting from major news organizations.

Alphabet, Microsoft, Amazon and Meta reported capital spending of about $209 billion for the quarter ended September 30, nearly all of it on data centers and the servers that fill them. Amazon led at $77.3 billion, followed by Alphabet at $51.4 billion, Microsoft at $45.2 billion and Meta at $34.9 billion. The total mixes two bases: Microsoft and Meta count equipment taken on finance leases, while Alphabet and Amazon report cash purchases. In cash alone, the four spent about $202 billion.

Two of the four spent more than their operations brought in. Alphabet’s free cash flow was negative $9.1 billion, its second negative quarter in a row, and Amazon’s has been negative over the past twelve months. Microsoft spent less than it planned because suppliers delivered late, and it expects the pace to pick up in early 2027, partly because memory costs more.

Alphabet Q3 2026: $51.4 billion of capex, negative cash flow and a record fall in the shares

Alphabet’s purchases of property and equipment were $51.36 billion, up from $23.95 billion a year earlier, against $42.29 billion of cash from operations. Revenue rose 25% to $127.6 billion, and Google Cloud more than doubled to $30.7 billion with operating income of $11.1 billion. Free cash flow was still negative $9.07 billion, after negative $5.86 billion in the June quarter.

The gap is being filled from outside. Long-term debt rose from $46.5 billion at the end of 2025 to $125.1 billion at September 30, and during the quarter Alphabet sold 36 million shares for $12.4 billion through an at-the-market program, with $27.6 billion still authorized. These are the first full results since the company raised $84.8 billion in equity in June, Fortune noted.

Alphabet held its 2026 guidance at $195 billion to $205 billion. “We continue to expect our capex to increase significantly in 2027, and will provide further details on our Q4 call,” Chief Financial Officer Anat Ashkenazi told analysts, according to CNBC.

Investors sold. Class A shares fell 12.6% on Thursday, from $324.89 to $283.82, the steepest one-day drop since the company’s 2004 listing, going by the daily closing prices; the previous record was 11.6% on March 16, 2020.

Microsoft FY27 Q1: $45.2 billion, late deliveries and CPUs that cost more

Microsoft’s capital expenditures were $45.2 billion for its quarter ended September 30, including $7.4 billion of finance leases; cash paid for property and equipment was $39.4 billion. That fell short of the more than $50 billion the company had forecast “as some third-party capacity deliveries we expected in Q1 were delayed,” Chief Financial Officer Amy Hood said on the call. Roughly three quarters of the spending went to short-lived assets, “primarily CPUs and GPUs, including higher memory and storage costs.”

Hood put calendar-2026 spending at approximately $170 billion, down from about $175 billion, CNBC reported. In the second half of the fiscal year, she expects spending “to accelerate primarily from CPUs, inclusive of higher memory and storage costs, and GPUs, as well as the 3P capacity deliveries that shifted to H2.” Demand is not the constraint. Azure revenue grew 48% to $33.2 billion, and Hood said “customer demand continues to exceed available supply.” OpenAI alone generated $10 billion of the quarter’s revenue, 11% of the total, GeekWire reported from Microsoft’s 10-Q. The same filing warns that Microsoft may change how it allocates scarce data center capacity, or what it charges for it. Free cash flow was $18.6 billion, and Hood said the company “will access additional sources of funding when we believe it is attractive to do so.”

Amazon Q3 2026: $77.3 billion in a quarter and $220 billion for the year

Amazon’s purchases of property and equipment were $77.26 billion, up from $35.10 billion a year earlier, and $215.2 billion over the trailing twelve months. Operating cash flow over the same period rose 29% to $168.3 billion, and trailing free cash flow was still an outflow of $42.4 billion, against an inflow of $14.8 billion a year earlier.

Chief Executive Andy Jassy held the full-year figure set in July: “We still expect 2026 cash CapEx of approximately $220 billion, the majority for AWS, and expect to spend meaningfully more in 2027 with a clear line of sight to attractive financial returns.” AWS grew 39% to $46.0 billion, and Jassy said it can grow “north of 40%” in each of 2027 and 2028. Its margins are improving, he said, “even with heightened component costs like memory and significant depreciation from the CapEx we’re investing.”

Meta’s $34.9 billion and the 2026 totals

Meta, which reported on October 21, spent $34.91 billion, counting $33.94 billion of equipment purchases and $0.96 billion of principal on finance leases, and its free cash flow was negative $2.12 billion. It narrowed its 2026 range to $135 billion to $145 billion and said it expects “to continue investing aggressively” next year.

Add up the four companies’ guidance and 2026 comes to roughly $720 billion to $740 billion. CNBC reported that hyperscaler capex is expected to top $1 trillion next year. The bill also lands twice: Alphabet’s quarterly depreciation of property and equipment rose to $8.4 billion from $5.6 billion a year earlier.

What $209 billion of hyperscaler capex means for IT budgets

The four are buying the same parts as everyone else. Hood’s “higher memory and storage costs” and Jassy’s “heightened component costs like memory” are the market an IT team meets at a server refresh. Samsung’s memory business said on October 29 that AI-driven demand in 2027 “will far exceed the industry supply,” and Intel reported the same day that its data center revenue rose 78% while client revenue fell 5%, with the PC slowdown expected to last at least through the first half of 2027. Intel could fill only about half its CPU orders in September, and PC shipments fell by a fifth in the third quarter as memory prices climbed.

Cloud capacity is spoken for before it is built. Jassy said the large blocks, “hundreds of megawatts or sometimes up to a gigawatt,” are reserved well in advance, and Microsoft’s filing now says it may reallocate or reprice scarce capacity, so a project that needs a particular GPU in a particular region is competing with those reservations. Neither company talked about raising cloud prices; Hood said each dollar of capex “has the potential to support more revenue.” The squeeze shows up instead in the hardware quote for anything run on premises.
