Alphabet Reaches $3 Trillion Market Cap, Joins Apple, Microsoft and Nvidia

Alphabet, the parent company of Google, has hit a market capitalization of $3 trillion for the first time. The company’s Class A shares closed up 4.6% at $251.88, while Class C shares rose 4.5% to $252.30, both ending at record highs.

The milestone makes Alphabet the fourth company in the world to reach a $3 trillion valuation, joining Apple, Microsoft, and Nvidia. Nvidia recently crossed $4 trillion, becoming the world’s most valuable company.

Alphabet’s latest surge was fueled by a favorable antitrust ruling in the U.S. A federal judge rejected calls from the Department of Justice to force the company to divest its Chrome browser and Android mobile operating system. Regulators had argued that Google held an illegal monopoly in search and related advertising.

Beyond regulatory relief, Alphabet is also gaining momentum from its strong cloud and AI businesses. In the second quarter, Google Cloud revenue grew by nearly 32%, beating expectations. The company’s investment in custom chips and its Gemini AI models is starting to pay off. These steps have also strengthened its position in the artificial intelligence market.

The $3 trillion milestone comes about 20 years after Google’s IPO and a little over 10 years after the creation of Alphabet as a holding company. Since Sundar Pichai took over as CEO in 2019, Alphabet has faced new challenges from regulators and competitors, while also steering the company toward the AI-driven future.
