Google’s parent company, Alphabet, became one of the world’s largest companies by market capitalization after Google reorganized its corporate structure in 2015.
In October 2015, Alphabet Inc. replaced Google Inc. as the publicly traded parent company. Google became the main subsidiary, while other ventures were separated into distinct Alphabet businesses, including so-called “Other Bets.”
The reorganization was intended to give investors clearer information about Google’s core internet businesses and its experimental projects. Google Search, advertising, YouTube, Android, and Google Cloud remained central to the group’s value.
A common mistake is treating Google and Alphabet as interchangeable stock-market names. Alphabet is the listed parent corporation, while Google is its principal subsidiary. Market-capitalization tables generally list Alphabet, even when people casually refer to the company as Google.
