GOOGL

The company traces its origins to a research project at Stanford University. Larry Page and Sergey Brin, both doctoral students, developed a method for ranking web pages by the links pointing to them, an algorithm they called PageRank. They founded Google in 1998, operating at first out of a rented garage. The search engine grew quickly because it returned more relevant results than the alternatives of the era, and the company found a durable way to make money when it began selling small text advertisements tied to search queries. That model, later organized around the AdWords and AdSense systems, turned a free consumer product into one of the most profitable advertising businesses ever built. Google went public in 2004 through an unusual auction style offering and used the capital and the attention to expand far beyond search.

In 2015 the founders reorganized the company. Google became a wholly owned subsidiary of a new parent called Alphabet Inc., and several projects that were unrelated to the core internet business were moved out from under Google and grouped together. The stated logic was to give the leaders of each venture more independence, to make the financials clearer by separating the mature advertising business from money losing experiments, and to give the founders room to pursue ambitious projects without those efforts dragging on Google's reported results. The structure has often been compared to a conglomerate model in which a strong cash generating core funds a set of separate businesses at different stages of maturity.

Alphabet reports its results in three parts. The largest by far is Google Services, which includes Google Search, YouTube, Android, Chrome, the Google Play app store, hardware devices such as the Pixel phone line, and consumer subscriptions including YouTube TV, YouTube Premium, and Google One. Google Services generates the bulk of company revenue, and most of that revenue comes from advertising sold against search results, YouTube videos, and the broader Google ad network. The second segment is Google Cloud, which sells computing infrastructure, data and analytics tools, and enterprise software and collaboration products to businesses. Google Cloud spent years as a heavy investment that lost money, then reached sustained profitability in the mid 2020s as it scaled. The third part is Other Bets, a collection of earlier stage businesses that operate largely outside the Google brand. The most prominent of these is Waymo, the autonomous driving unit that runs commercial robotaxi services in several United States cities. Other Bets also includes life sciences and health ventures and a handful of smaller projects, and as a group it produces little revenue relative to its spending.

The economic foundation of the company is the search advertising business, and its durability rests on a set of reinforcing advantages. Google Search benefits from enormous scale, because every additional query and click provides data that helps refine results and ad targeting, which in turn attracts more users and more advertisers. The Android operating system and the Chrome browser, both of which are distributed at no cost, funnel a large share of the world's web activity toward Google's services. The company has also paid substantial sums over the years to be the default search engine on devices and browsers it does not control, including those made by other companies. The result is a business with high margins, low marginal cost per query, and a flywheel in which usage, data, and advertiser demand strengthen one another. YouTube adds a second large advertising and subscription franchise, and the Google Cloud business gives Alphabet a foothold in the enterprise market that complements its consumer reach.

Competition is intense across every part of the company. In digital advertising, Alphabet competes with Meta, Amazon, and a growing field of retail and streaming platforms that sell ads against their own audiences. In cloud computing, it sits behind Amazon Web Services and Microsoft Azure in market share, and it competes hard on price, performance, and the strength of its data and artificial intelligence tools. In artificial intelligence specifically, the rise of conversational systems from OpenAI, Microsoft, Anthropic, and others has created the first serious challenge in years to the way people find information, since some queries that once went to a search box now go to a chatbot. Alphabet has responded by building its own family of large models under the Gemini brand and by weaving generative answers directly into search results. By the mid 2020s the Gemini consumer application had grown to hundreds of millions of monthly users, and the company reported rapid growth in developers and enterprises using its models through its cloud platform. The competitive question is whether Alphabet can defend its search economics while the interface to information shifts toward conversational and assistant style products.

Leadership sits with Sundar Pichai, who has served as chief executive of both Google and Alphabet since the founders stepped back from day to day management in 2019. Pichai came up through the product side of the company, having led the development of Chrome and later overseen Android and the core Google products before taking the top job. The finance organization is led by Anat Ashkenazi, who became chief financial officer in 2024 after a long career at the pharmaceutical company Eli Lilly. A separate and influential part of the company is Google DeepMind, the artificial intelligence research division formed by combining the original DeepMind laboratory with Google's internal Brain team, led by Demis Hassabis. DeepMind is responsible for much of the fundamental research behind Alphabet's models and has produced widely recognized scientific work, including systems for predicting protein structures.

The forward strategy is organized around artificial intelligence and the infrastructure to support it. Alphabet has committed to very large capital spending on data centers and on custom chips, including its own Tensor Processing Units, designed to train and run large models efficiently and to reduce dependence on outside chip suppliers. The company is integrating its Gemini models across its product line, from search and the Workspace productivity suite to Android and the cloud platform, with the aim of keeping its core franchises relevant as user behavior changes. Waymo continues to expand its autonomous ride service into new cities and represents the most commercially advanced of the Other Bets. The underlying bet is that Alphabet's combination of research talent, proprietary data, global distribution, and owned infrastructure will let it lead the transition to artificial intelligence rather than be displaced by it.

The risks are specific and material. The clearest is regulatory and legal pressure. In 2025 a United States federal court found that Google had unlawfully maintained a monopoly in online search and search advertising, and the remedies that followed targeted the default search agreements and required certain data sharing, while stopping short of forcing a breakup or the sale of Chrome or Android. Separate cases have challenged the company's advertising technology business, and regulators in Europe and elsewhere continue to scrutinize its conduct. A second risk is the concentration of revenue in advertising, which makes the company sensitive to economic cycles and to any structural shift away from search. A third is the disruption risk from artificial intelligence itself, since the same technology Alphabet is racing to deploy could erode the search advertising model that funds everything else if users and advertisers migrate to competing assistants. The heavy capital spending on artificial intelligence infrastructure also carries the risk that returns arrive more slowly than the investment, pressuring margins in the meantime.

A reader on this page should understand one structural detail about the stock itself, because Alphabet has three classes of shares with different voting rights. Class A shares, which trade under the ticker GOOGL, carry one vote per share. Class C shares, which trade under the ticker GOOG, carry no voting rights at all and were created so the company could issue stock for acquisitions and employee compensation without diluting insider control. The two publicly traded classes have nearly identical economic claims on the company and usually trade within a fraction of a percent of each other in price, with GOOGL sometimes carrying a very small premium for its voting rights. The third class, Class B, carries ten votes per share, is held by the founders and a small group of insiders, and is not traded on any public market. Through these super voting Class B shares, Larry Page and Sergey Brin retain majority control of shareholder voting power even though they own a much smaller fraction of the total economic shares and have stepped away from running the company. The practical effect is that ordinary public investors in either GOOGL or GOOG have limited ability to influence corporate decisions through their votes.

Taken together, Alphabet Inc. is a company whose identity rests on one dominant business, internet search and the advertising sold around it, surrounded by a widening set of franchises in video, mobile software, cloud computing, and artificial intelligence, with a few longer horizon ventures held under the same parent. Its history is one of converting a research insight into a flywheel of scale, data, and distribution that has proven difficult for rivals to break. Its present is defined by the tension between defending that flywheel and reinventing it for an era in which artificial intelligence is reshaping how people find and use information, all while facing the most serious antitrust pressure of its existence. The dual class voting structure means the founders, not public shareholders, hold ultimate control. How the company manages the shift to artificial intelligence, the cost of the infrastructure that shift requires, and the outcome of its legal battles will shape its trajectory in the years ahead.
