Alphabet Inc. (GOOGL) perpetual market

Alphabet is the parent company of Google, one of the world's dominant technology firms, and its Class A shares trade under GOOGL. Google was founded in 1998 by Larry Page and Sergey Brin around a breakthrough web search engine, and it built an advertising business of enormous scale on top of Search, YouTube and its ad networks, which still generate most of Alphabet's revenue. The company reorganized under the Alphabet holding structure in 2015 to separate Google from longer-term bets. Its portfolio spans the Android mobile operating system, the Chrome browser, Google Cloud, the Workspace productivity suite and the Waymo self-driving unit. Alphabet is a leader in artificial intelligence through its DeepMind and Gemini efforts, a strength that is also reshaping how it approaches search. As a mega-cap anchor of major indices, it faces significant antitrust scrutiny over the market power of its search and advertising businesses.
