Alphabet reported strong Q2 results with Google Search revenue reaching a record $63.3 billion（約10兆円） and Google Cloud revenue surging 82% to $24.8 billion（約4兆円）, driven by AI features and cloud platform demand. However, the company raised its 2026 capital expenditure forecast to $195–$205 billion（約33兆円） (from $180–$190 billion（約30兆円）) to build data center capacity and meet a $514 billion（約82兆円） AI customer backlog, which will depress earnings over several years. The stock fell around 7% on the news and is down 20% from its recent high, leaving investors to weigh whether lower valuations offer a buying opportunity or whether the earnings headwind warrants caution.

Alphabet reported strong Q2 results—Google Search revenue hit a record $63.3 billion（約10兆円） (up 17% year-over-year) and Google Cloud revenue surged 82% to $24.8 billion（約4兆円）—but announced it would spend $195–$205 billion（約33兆円） on AI data centers in 2026, up from its prior $180–$190 billion（約30兆円） forecast. The stock fell around 7% immediately after the announcement and is now down 20% from its recent all-time high.
Why it matters
The higher capex spending will be depreciated over several years, eroding Alphabet's profits for the foreseeable future and potentially suppressing stock returns. Excluding a $98 billion（約16兆円） gain from investment holdings (unrelated to operations), Alphabet actually generated negative free cash flow of $5.8 billion（約9300億円） in Q2. While the company's AI products—including AI Overviews and AI Mode, which has 1 billion monthly active users—are driving search growth and customer demand for cloud capacity (evidenced by a $514 billion（約82兆円） order backlog), the massive infrastructure spend creates earnings risk if AI demand does not sustain.
What to watch
Management's capex guidance in the coming quarters. Alphabet's P/E ratio (24.3) is lower than the Nasdaq-100 index (33.4), making the stock appear cheap on the surface, but investors may find greater value if the company adopts a more cautious approach to infrastructure spending.
Alphabet released its Q2 2026 operating results (for the quarter ended June 30) after the market close on Wednesday, reporting strong revenue growth across its AI-focused businesses but revealing plans for sharply increased capital spending. Google Search, Alphabet's largest revenue source, generated a record $63.3 billion（約10兆円） in revenue during Q2, up 17% from the year-ago period. The company credited AI-powered features for driving this growth: AI Overviews, which appear above traditional search results and use text, images, and links to provide AI-generated answers, and AI Mode, a chatbot-style interface launched globally last October that has already reached 1 billion monthly active users and allows users to ask follow-up questions on their original queries.
Google Cloud also posted exceptional results, with revenue surging 82% during Q2 to $24.8 billion（約4兆円）. The platform operates data centers worldwide housing specialized AI chips and rents computing capacity to other businesses. Alphabet also offers Gemini Enterprise, a platform where businesses can use that capacity to build finished AI chatbots, agents, and other applications; 90% of the Fortune 100 companies are already using it. The strong performance reflects consistent demand for AI-related services, making Google Cloud Alphabet's fastest-growing segment over the last couple of years.
But the infrastructure demands underpinning this growth are immense. As of June 30, Google Cloud had a $514 billion（約82兆円） order backlog, a $50 billion（約8兆円） increase from Q1 2026 just three months earlier, with most of that backlog from AI customers waiting for data center capacity. To meet these needs, Alphabet announced that capital expenditures during 2026 would fall between $195 billion（約31兆円） and $205 billion（約33兆円）—a significant revision upward from the company's previous guidance of $180 billion（約29兆円） to $190 billion（約30兆円）, and a massive leap from $91 billion（約15兆円） spent in 2025. Because data centers and chips are typically depreciated over several years rather than expensed immediately, these enormous capex sums will erode Alphabet's reported profits and free cash flow for years to come.
The market responded sharply. Alphabet stock fell around 7% immediately following the earnings release and is now down 20% from its recent all-time high. The sell-off reflects investor concern that the capex ramp could suppress earnings growth for an extended period, even though the company's AI products are driving customer acquisition and usage. While Alphabet's Q2 earnings jumped 294% year-over-year to $9.11 per share, that figure is misleading: $98 billion（約16兆円） of the gain came from unrealized gains on investment holdings in companies like Anthropic and Space Exploration Technologies, unrelated to core operations. When those investment gains and capex are factored out, Alphabet actually generated negative free cash flow of $5.8 billion（約9300億円） during Q2. Alphabet trades at a lower price-to-earnings ratio (24.3) than the Nasdaq-100 index (33.4), suggesting cheaper valuations than big-tech peers, but the stock may be more expensive than it appears when accounting for the earnings headwind from infrastructure depreciation and the one-time investment gains masking operational reality.
Alphabet finds itself at a critical juncture common to hyperscalers (large cloud providers) investing heavily in AI infrastructure. The company's core AI businesses are performing exceptionally: Google Search's record $63.3 billion（約10兆円） in revenue reflects the success of AI-powered features like AI Overviews and AI Mode in increasing user engagement and advertising exposure, while Google Cloud's 82% revenue surge to $24.8 billion（約4兆円） demonstrates robust demand for AI computing services. The $514 billion（約82兆円） order backlog—and its $50 billion（約8兆円） quarterly increase—underscores that enterprise customers are competing fiercely for data center capacity to build and deploy AI applications.
However, the accounting reality complicates the picture. Alphabet's Q2 earnings surged 294% year-over-year to $9.11 per share, but $98 billion（約16兆円） of that came from gains on investments in companies like Anthropic and Space Exploration Technologies, not from core operations. Excluding those gains and accounting for the massive capex, Alphabet generated negative free cash flow of $5.8 billion（約9300億円） in Q2. The company's raised capex guidance—now $195–$205 billion（約33兆円） for 2026, compared with $91 billion（約15兆円） last year—will be depreciated gradually, meaning profit margins will be compressed for years even if demand holds steady. The risk is real: if AI computing capacity becomes oversupplied or enterprise demand falters, those investments will have little to show for the earnings damage they inflict.
