Alphabet reported a 25% increase in third-quarter revenue to $127.58 billion on Wednesday, October 28, as Google Cloud sales more than doubled to $30.71 billion, highlighting growing demand for artificial intelligence infrastructure even as the company’s expanding investments weighed on cash flow.
According to Alphabet’s quarterly earnings release, consolidated revenue increased from $102.35 billion a year earlier. Google Cloud revenue surged 103% from $15.16 billion, while operating income rose 30% to $40.58 billion.
The results revealed a significant contrast between accelerating cloud revenue and Alphabet’s financial costs. Net income available to common shareholders declined to $26.17 billion from $34.98 billion, and diluted earnings per share fell to $2.12 from $2.87.
The earnings release attributed much of the pressure on net income to losses on equity investments, rather than deterioration in the company’s underlying operating profit.
Google Cloud accounted for approximately $15.55 billion of Alphabet’s $25.23 billion increase in consolidated revenue, according to my calculation using the company’s reported segment figures. That means Cloud contributed roughly 62% of the total year-over-year revenue increase, despite representing approximately 24% of current-quarter sales.
This distinction matters for investors evaluating whether Alphabet’s AI infrastructure spending is generating measurable commercial returns. Cloud is becoming a much larger contributor to growth, even while Google’s established advertising business continues to provide most of the company’s revenue.
Google Cloud operating income increased from $3.59 billion to $11.12 billion, more than tripling from the same quarter last year. Its operating margin expanded from approximately 23.7% to 36.2%, based on reported segment revenue and operating income.
Alphabet attributed Cloud’s performance to enterprise AI infrastructure, AI solutions, core Google Cloud Platform services and demand for its Tensor Processing Unit systems. These specialized processors support large-scale AI computing workloads. Chief Executive Officer Sundar Pichai said in his October 28 earnings remarks that AI infrastructure and enterprise demand were major drivers of Cloud growth.
The acceleration also brings new attention to the cost of expanding computing capacity, a central issue in Investozora’s earlier coverage of AI spending across Microsoft, Alphabet and Amazon.
Alphabet’s Google Services division generated $96.30 billion in revenue, up 11% from $87.05 billion a year earlier. Google Search and other advertising revenue increased 12% to $63.35 billion, while YouTube advertising revenue rose to $11.21 billion from $10.26 billion.
Google’s total advertising revenue reached $82.01 billion, compared with $74.18 billion a year earlier. Although Cloud grew substantially faster, advertising still represented approximately 64% of consolidated revenue.
Pichai said AI investments were contributing to growth in Search queries, including commercial searches, with year-over-year query growth reaching its highest rate in five years. That is management’s account of user activity, rather than an independently disclosed measure of AI-driven advertising profitability.
Alphabet also reported that its Gemini application had reached one billion users and that its first-party AI model APIs were processing nearly 32 billion tokens per minute. However, the company’s cash-flow figures present a more complicated picture.
Alphabet generated $42.29 billion in operating cash flow during the third quarter but spent $51.36 billion on purchases of property and equipment. Its reported non-GAAP free cash flow consequently stood at negative $9.07 billion.
Free cash flow had already been negative $5.86 billion in the second quarter, following positive free cash flow of $10.12 billion in the first quarter. These figures show that capital investment exceeded cash generated from operations in each of the latest two quarters, even as revenue and operating profit continued to grow. They do not establish that Alphabet’s core business was operating at a loss.
In previous market coverage, Investozora examined the broader investor debate surrounding AI-related investment and the economic returns expected from that spending.
The latest earnings provide another measurable part of that debate: Cloud operating profitability improved sharply, but consolidated free cash flow remained negative.
Alphabet’s investment portfolio also contributed to the divergence between operating profit and reported earnings. The company disclosed an $8.7 billion net loss on equity securities, reducing net income by approximately $6.7 billion after tax and diluted earnings per share by $0.55.
The loss helps explain why net income declined even though operating income increased. It also means the headline earnings decline should not be interpreted as an equivalent deterioration in Google’s advertising or cloud operating performance. The distinction is relevant to technology investors following Nasdaq movements and the broader reassessment of AI-related valuations.
In early after-hours trading following the announcement, Alphabet shares declined sharply as investors weighed the company’s results against expectations for revenue, advertising performance and cash generation, according to Reuters reporting. Those initial moves should not be treated as the following day’s closing price.
Alphabet’s financial disclosures show that its AI investments are already associated with substantial Cloud revenue and operating profit growth. The unresolved question is how quickly that expanding business can generate sufficient cash to cover the company’s escalating infrastructure expenditures.
Management’s expectations for additional capital investment in 2027 make future spending guidance, Cloud operating margins and quarterly free cash flow important measurements for investors assessing the sustainability of that growth.
