Alphabet first exceeded a $1 trillion market capitalization in January 2020.
Alphabet, Google’s parent company, passed the $1 trillion valuation threshold on January 16, 2020. It became the fourth U.S. technology company to reach that level, following Apple, Amazon, and Microsoft.
Alphabet was created in 2015 as part of a corporate restructuring. Google became its largest subsidiary, while other projects were grouped under the new parent company. This structure separated the core internet business from longer-term ventures such as self-driving technology and life sciences research.
Alphabet’s valuation has traditionally been driven by Google Search advertising, YouTube, and the Google Cloud business. The company also owns Android, the world’s widely used mobile operating system. The market-cap milestone is sometimes incorrectly attributed to Google itself, but the publicly traded parent company since the restructuring has been Alphabet, with Google operating as its principal subsidiary.
