Alphabet Q3 2026: Cloud Revenue Doubles as Capex Outruns Cash Flow

Alphabet's third quarter of 2026 had two stories, and the headline number hides both. The operating business had its strongest quarter yet: operating income rose 30% to $40.6 billion, and Google Cloud doubled its revenue at a 36% operating margin. But this quarter Alphabet's AI buildout outran the cash its business produced. Purchases of property and equipment reached $51.4 billion against $42.3 billion of operating cash flow, so free cash flow was negative $9.1 billion, and the gap was filled with $29 billion of new notes and $12.4 billion of newly issued stock. GAAP net income fell 24% to $26.5 billion, and that drop says little about either story.

Net income fell because a paper gain reversed, not because the business weakened​

Revenue rose 24.7% to $127,577 million and operating income rose 29.9% to $40,576 million, lifting operating margin to 31.8% from 30.5% (earnings release). Below the operating line the picture flips. Other income and expense was a $8,221 million loss against a $12,759 million gain a year ago, a swing of almost $21 billion. CFO Anat Ashkenazi attributed it "primarily to unrealized loss from our investment in SpaceX from a decline in its stock price in the third quarter" (call transcript).

That is the same line that inflated the first half. The ledger's income statements put it next to net income in each period:

Each row is one reported period. Revenue and other income are credits, so they carry a minus sign; Expenses:OtherNet is a net other loss, and Equity:Adjustments is net income. Other income was $37,716 million in the first quarter and $97,983 million in the second, against net income of $62,578 million and $112,193 million. In the third quarter it turned into an $8,221 million expense. Across the nine months, other income contributed $127,478 million of $201,239 million in net income, about 63% by our computation. That is the reason our Q2 analysis read the operating line rather than EPS, and Q3 shows what happens when the mark moves the other way. Diluted EPS fell to $2.12 from $2.87.

Cloud supplied six of every ten new revenue dollars, at a higher margin​

Google Cloud revenue rose 103% to $30,709 million from $15,157 million. Of the $25,231 million total revenue increase, Cloud supplied $15,552 million, about 62% by our computation. Google Services grew 10.6% to $96,302 million, with Search & other up 12% to $63,350 million.

The margin moved more than the revenue. Cloud operating income rose to $11,121 million from $3,594 million, a 36.2% segment margin against 23.7% a year earlier. The release credits enterprise AI infrastructure and sales of TPU systems, Alphabet's own AI chips sold as complete systems. On the call, Ashkenazi put Cloud's backlog at $561 billion and said she expects "just over 55%" of it to become revenue within 24 months.

The quarter's expense treemap shows $51,419 million of cost of revenue, $20,640 million of research and development, $14,942 million of sales, marketing and G&A, and the $8,221 million other loss. The ledger records revenue as one total; the segment split above comes from the earnings release, and the ledger carries it as a comment in the period file.

Two lines grew faster than revenue and point to next year's margins. Depreciation of property and equipment rose 49% to $8,369 million in the cash-flow statement. Ashkenazi warned that the buildout "will continue to weigh on the P&L in the form of higher depreciation expenses" and that renting third-party compute from late Q3 brings "margin headwinds in the near term" for Cloud.

Capex passed operating cash flow, and debt and new shares made up the difference​

Operating cash flow fell 12.6% to $42,290 million, partly because Alphabet is building TPU inventory before it can recognize the revenue. Inventory on the balance sheet rose to $13,308 million from $2,439 million at the end of 2025. Purchases of property and equipment more than doubled to $51,355 million from $23,953 million. Free cash flow, operating cash flow minus those purchases, was negative $9,065 million, against $24,461 million a year ago.

For a reader who runs a business, this is the clearest lesson of the quarter: profit and cash can point in opposite directions. A dollar of capital spending leaves the bank account today, but it reaches the income statement only as depreciation, spread over years. Ashkenazi said servers and networking equipment, about 65% of this quarter's technical-infrastructure spend, "generally have useful lives of 6 years." So Alphabet can report a 30% operating-income gain in the same quarter its cash flow turns negative. Our depreciation guide works through the same mechanics with numbers a small business can check.

The financing section shows how the gap was closed. Alphabet issued $28,996 million of debt and repaid $3,626 million, raised $12,371 million by selling new Class A and Class C shares through its at-the-market program, and bought back no stock, against $11,504 million of repurchases a year earlier. Diluted share count rose to 12,368 million from 12,203 million. The balance sheet records where that leaves the company:

Long-term debt is a liability, a credit, so a growing balance plots as a falling line. It was $14,701 million at the end of 2022 and $10,883 million at the end of 2024, when Alphabet was still paying debt down. It ended 2025 at $46,547 million and reached $125,102 million on September 30, 2026, after rising in each quarter of the year. Net property and equipment over the same span went from $112,668 million to $372,827 million, including $126,230 million added since December. The press release reports the quarter's borrowing; the ledger shows that the borrowing began only once the buildout outgrew a balance sheet that had funded it from cash for years.

What to watch in the fourth quarter​

• The rest of the capex guide. Alphabet kept 2026 capex at $195 billion to $205 billion. Purchases of property and equipment were $131,953 million through September, which implies roughly $63 billion to $73 billion in the fourth quarter by our computation, before the "significant" increase Ashkenazi expects in 2027.
• Cloud margin under rented capacity. The 36.2% segment margin is the number at risk if third-party compute costs more than Alphabet's own data centers, as Ashkenazi signalled.
• TPU inventory converting to revenue. Kurian said all TPU-system inventory is "associated with committed contracts." The test is whether the $13.3 billion of inventory turns into recognized revenue and lifts operating cash flow, rather than continuing to grow.
• Other income. With large stakes marked to market, the line that added $135.7 billion in the first half and took away $8.2 billion in the third will keep moving GAAP earnings in both directions. The operating line is the one to compare across quarters.
