Facebook first surpassed a $1 trillion market capitalization in 2021.
Facebook’s parent company crossed the milestone in June 2021, after a U.S. court dismissed major antitrust claims brought against the company. At that time, the corporate name was Facebook, Inc.; it changed to Meta Platforms, Inc. in October 2021.
The company’s valuation was supported by its massive user base and advertising businesses across Facebook, Instagram, and WhatsApp. Its size also reflected investors’ expectations for continued digital advertising growth.
The name change can create confusion when identifying the correct answer. Meta is the company’s current corporate name, but Facebook is the name used when it first passed the trillion-dollar threshold. The milestone also refers to market capitalization, not annual sales or cash holdings.
