Alphabet hits $3 trillion market cap for the first time, joins the exclusive club with Apple, Microsoft and Nvidia as Google stock jumps 3.45%
Alphabet (Google’s parent company) has hit a market capitalization of $3 trillion for the first time on Monday, September 15, 2025. This milestone puts Alphabet in an elite club alongside Nvidia, Microsoft, and Apple, which are the only other U.S. companies to have reached such a valuation.
The surge in Alphabet’s stock price (up about 3.45% to 4.7% on the day) is driven by renewed optimism around the company’s artificial intelligence (AI) products, strong earnings, and a favorable antitrust ruling allowing it to retain control of Chrome and Android. The ruling removed a significant regulatory risk that had weighed on the stock, boosting investor confidence.
