Alphabet said on 28 October 2026 that its revenues rose 25% to $127.6 billion in the third quarter. Its operating activities brought in $42.3 billion of cash in the same quarter, and it spent $51.4 billion on property and equipment.
This explainer walks through how Google’s parent makes money now and where that cash went, using only the figures in Alphabet’s release. Every ratio below is our arithmetic.
A vertical news Short narrated from the published headlines and opening lines of this piece and three related FourWeekMBA pieces.
Business Pill · Vertical Integration
An evergreen Business Engineer explainer on vertical integration, why every layer takes a cut. It explains the general idea only and does not discuss Alphabet’s results.
The key insight: By our arithmetic from Alphabet’s release, Google Cloud supplied 61.6% of the quarter’s $25.2 billion revenue increase, while Google Services still earned 96.5% of group operating income.
Alphabet reports three segments. Google Services “includes products and services such as ads, Android, Chrome, consumer devices, Google Maps, Google Play, Search, and YouTube”. It had $96.3 billion of revenues in the quarter.
Google Cloud “includes infrastructure and platform services, applications, and other products and services for enterprise customers”. It had $30.7 billion. Other Bets, which earns revenues “primarily from the sale of autonomous transportation services and internet services”, had $372 million.
A fourth line, Alphabet-level activities, is not a segment. It collects costs Alphabet does not allocate, and the release says these “primarily reflect expenses related to our shared AI research and development”.
Alphabet segment revenues by line as a share of the total, excluding hedging, Q3 2025 against Q3 2026: Search & other fell from 55% to 50% and Google Cloud rose from 15% to 24%. Shares are our arithmetic. Source: Alphabet Q3 2026 results release, 28 October 2026.
Advertising Is Still the Biggest Earner
Inside Google Services, Google advertising brought in $82.0 billion: $63.4 billion from Search & other, $11.2 billion from YouTube ads and $7.5 billion from Google Network. Subscriptions, platforms and devices added $14.3 billion.
By our arithmetic, Search & other was 49.7% of segment revenues in the quarter, excluding hedging, against 55.2% a year earlier. Google Cloud was 24.1%, against 14.8%.
Where the Growth Came From
Total revenues rose by $25.2 billion from a year earlier. Google Cloud revenues rose by $15.6 billion, to $30.7 billion from $15.2 billion, and Google Services by $9.3 billion. By our arithmetic, Cloud supplied 61.6% of the increase.
The release says Cloud growth was “led by strong growth in Google Cloud Platform (GCP) across enterprise AI infrastructure and enterprise AI solutions, as well as core GCP services”, and that “TPU systems sales were also a meaningful contributor to revenuegrowth”.
What TPU Systems Sales Are
TPUs are the AI chips Google designs. Alphabet’s segment description says Google Cloud “generates product revenues primarily from the sale of TPU systems”, alongside services revenues from consumption-based fees and subscriptions.
Operating income was $40.6 billion. Google Services earned $39.2 billion and Google Cloud $11.1 billion, against $3.6 billion a year earlier. Other Bets lost $2.0 billion, and Alphabet-level activities lost $7.7 billion.
By our arithmetic, Google Services’ operating income was 96.5% of the group total, and Cloud’s 27.4%, against 11.5% a year earlier. The two losing lines took away $9.7 billion.
Where the $42.3 Billion of Cash Went
Alphabet’s cash flow statement shows $42.3 billion of net cash from operating activities in the quarter and $51.4 billion of purchases of property and equipment. The release’s free cash flow, which it defines as the first minus the second, was negative $9.1 billion.
It paid $2.9 billion of dividends on its preferred and common stock and repurchased no stock, against $11.5 billion of repurchases a year earlier. It took in $29.0 billion from issuing debt, net of costs, including $28.7 billion of senior unsecured notes, and $12.4 billion from issuing common stock.
At 30 September Alphabet held $265.1 billion of cash, cash equivalents and marketable securities, against $126.8 billion at the end of 2025. Long-term debt was $125.1 billion, against $46.5 billion.
As we read the release, Google Cloud now reports two kinds of revenue: services revenues from consumption-based fees and subscriptions, and product revenues that Alphabet says come primarily from the sale of TPU systems.
Sundar Pichai, Alphabet’s chief executive, said in the release: “Our deep full stack approach is driving momentum across the business”.
By our arithmetic, the quarter’s purchases of property and equipment were 1.21 times its net cash from operating activities: $51.4 billion against $42.3 billion.

“We’re also seeing strong demand for our TPU systems across a wide range of customers”
Three Implications
FOR ADVERTISING Search & other revenues grew 12%, according to the release, yet fell to 49.7% of segment revenues excluding hedging from 55.2% a year earlier, by our arithmetic.
FOR GOOGLE CLOUD Its operating income rose to $11.1 billion from $3.6 billion, and the release says TPU systems sales were a meaningful contributor to its revenuegrowth.
FOR THE BALANCE SHEET Alphabet’s long-term debt was $125.1 billion at 30 September against $46.5 billion at the end of 2025, and its cash flow statement shows no stock repurchases in the quarter.
The framework argues: “That is why the AI economy is not a list of companies racing each other.” It describes a layered industrial stack in which the binding constraint sits at a different layer than it did six months earlier.
Alphabet’s release of 28 October reports revenue from several of those layers at once: TPU systems, cloud infrastructure and platform services, model APIs and consumer products. The framework does not discuss these figures.
What Is Not Established
The release gives no separate figure for TPU systems revenue, no Google Cloud backlog and no capital expenditure outlook. It does not say how much of the Alphabet-level line is AI research in dollars. Anything said on the earnings call is not included here.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
Alphabet’s release shows Google Services, led by advertising, still producing most of the group’s revenues and operating income, while Google Cloud, which now sells TPU systems as well as services, supplied 61.6% of the quarter’s revenuegrowth by our arithmetic. Its $51.4 billion of purchases of property and equipment was larger than its $42.3 billion of operating cash, and in the same quarter it issued $29.0 billion of debt and $12.4 billion of common stock.
