Alphabet Inc. (GOOGL)
Thesis verdict: holds, with conditions — cloud revenue and profit are growing explosively, and more than $500B of performance obligations lock in long-term demand; but a single quarter's $44.9B of capex already exceeds operating cash flow, forcing large-scale debt and equity financing, so the loop depends heavily on absorbing compute depreciation and holding margins through the AI price-cut wave.
The company makes its money mainly from digital advertising and cloud computing. Google Services (Google Search, YouTube advertising and subscription services) is the core cash generator, charging advertisers; Google Cloud provides enterprise customers with compute infrastructure (GCP) and the office suite (Workspace), billed by compute consumption or software subscription; Other Bets covers frontier ventures such as the self-driving unit Waymo. Money first flows into the ad-serving system and the cloud billing platform, which form the company's cash inlets.
Looking at the Q2 2026 mix of revenue and profit, the hierarchy is very clear. Google Services is 78.9% of total revenue and 81.7% of operating income, and contributed 51.3% of the year-over-year increase; its specific core contractual obligation is $16.18B of traffic acquisition costs (TAC, the fees paid to distribution channels to keep default search-engine placement). Google Cloud is 20.7% of revenue and 18.2% of operating income, but contributed 47.7% of the year-over-year increase — very strong momentum; its core contract is $51.39B of remaining performance obligations (RPO, orders customers have signed but that have not yet been recognized as revenue). By contrast, Other Bets is only 0.3% of revenue with an operating loss of $1.8B (−3.7% of operating income); unallocated AI R&D and similar spending is −11.9% of operating income. The company's heavy-asset infrastructure also carries $707B of long-term purchase and energy contracts and $85.2B of leases not yet commenced.
Operationally, both main segments are highly active. Google Cloud is on fire: news disclosed a nuclear-power agreement with Georgia Power (2026-09-23) to secure energy supply for compute; management's discussion and analysis (MD&A) confirmed that TPU systems have begun external sales; and cloud revenue surged 82% year over year. Google Services keeps expanding steadily: news shows Experian (2026-09-24) connecting to Gemini to extend commercial use cases, and search query volume keeps rising, though it also faces diversion pressure from competing tools.
By the layered structure of the value chain (the value stack — a layered system from physical infrastructure at the bottom to software entry points at the top): Google Cloud spans capital-intensive manufacturing and physical conversion (L2, the underlying compute facilities) and workflow and execution orchestration (L4, the enterprise application-development platform). At the bottom are heavy-asset data centers and TPU compute clusters facing enormous depreciation pressure; on top, the Vertex AI development platform and Gemini Enterprise lock in customers' model fine-tuning and data-governance processes directly. Although raw compute is going through a fierce price-cut wave — OpenAI and Anthropic cutting prices 40%–50% (2026-09-23) shows pricing power over pure compute is weakening — Alphabet has effectively resisted commoditization of the underlying hardware through the stickiness of its upper toolchain. Google Services sits firmly in the top-layer entry control and governance layer (L5, the digital gateway). As the world's largest gateway for traffic and search-intent distribution, it firmly controls the monetization rules of commercial advertising. By integrating financial services such as Experian deep into Gemini, the company is gradually penetrating from a simple search box into deep personal financial management and daily enterprise workflows, where users' switching costs are extremely high.
