Alphabet is the parent corporation of Google and has the stock ticker GOOG.
Google became a subsidiary of Alphabet in 2015, when the founders reorganized the business into a holding-company structure. Alphabet owns Google’s internet businesses, including Search, YouTube, and Google Cloud, while also overseeing other ventures and investments.
Alphabet has two widely traded share classes associated with the tickers GOOG and GOOGL. GOOG generally represents Class C shares without voting rights, while GOOGL generally represents Class A shares with one vote per share. This is why both tickers can appear in market-cap discussions about the same corporate group.
The reorganization allowed Google’s core internet operations to remain distinct from experimental or longer-term projects. Alphabet is a major market-cap company, but it should not be confused with Google as a separate publicly traded parent: Google itself is the subsidiary.
