How to Track AI Metrics in Alphabet Earnings: Cloud Revenue, TPU Systems, and CapEx

When to use this guide ​

• Sell-side and buy-side analysts and retail investors tracking hyperscaler AI infrastructure spending.
• Readers who need to quickly locate AI-related disclosures in Alphabet's official earnings release and call notes.
• Researchers following TPU external sales, cloud backlog, and capex guidance.

Context: Alphabet released its Q3 2026 earnings on October 28, 2026: total revenue $127.577B, up 25% YoY; Google Cloud revenue $30.709B, up 103% YoY (vs. $15.157B a year earlier).

Steps ​

1. Locate segment revenue: open the segment table in the official earnings release; start with Google Cloud revenue and its YoY growth ($30.709B, +103% YoY this quarter), and separate it from Google Services so the group growth rate is not mistaken for cloud growth.
2. Identify TPU system sales contribution: Alphabet says Cloud product revenue comes mainly from TPU system sales, and TPU system sales were a meaningful contributor to growth this quarter; per Converge Digest's notes from the October 28 call, TPU 8t/8i delivers about 2.7x the training performance of the previous generation and about 80% better inference price-performance, with external TPU sales extending to customers such as Oracle and Crux AI and third-party facilities, ramping from 2027.
3. Check capex: find additions to property and equipment in the cash flow statement — officially $51.355B in Q3 and $131.953B year-to-date; per Converge Digest's call notes, the 2026 capex guidance is maintained at $195–205B and will increase significantly in 2027; verify actual spending against that guided range.
4. Read free cash flow alongside capex: Alphabet reported Q3 free cash flow of -$9.065B; read FCF together with the $51.355B quarterly capex to interpret the short-term cash pressure of the AI infrastructure cycle — do not equate negative FCF directly with operating deterioration.
5. Track demand-side metrics: per Converge Digest's call notes, cloud backlog stands at $561B, with slightly more than 55% expected to convert to revenue within 24 months, and future purchase commitments total $924B; Alphabet also says first-party model APIs process nearly 32 billion tokens per minute, more than 4x a year ago, and Gemini has reached 1 billion users — verify each management metric against the call transcript.

Notes ​

• The $195–205B capex guidance, the $561B cloud backlog, and the $924B future purchase commitments come from Converge Digest's summary of the October 28 call, not from the written release; cite them as call-basis figures.
• The negative free cash flow (-$9.065B) is tied to peak capex; when judging earnings quality, read it separately from operating cash flow.
• External TPU sales are expected to ramp from 2027; current quarterly contributions are ramp-stage figures and should not be linearly extrapolated.
• The more-than-4x token growth and 1 billion Gemini users are management-stated metrics; periods and definitions follow the call transcript.
