Alphabet hits $3 trillion valuation in AI boom and antitrust court victory
Google’s parent Alphabet has become the fourth company in history to reach a $3 trillion market valuation, as investors’ enthusiasm for artificial intelligence and from a favorable American antitrust ruling drives stocks to record highs.
Shares of California-based Group rose more than 4% on Monday, pushing their market cap to $3.04 trillion. The stock has risen 31% so far this year, receiving strong revenue, fast AI adoption and landmark legal probation.
This milestone brings letters together with Nvidia, Microsoft and Apple into rare companies. NVIDIA crossed $4 trillion in July to become the world’s most valuable company and provided the stock market with the ground for the stock market after Trump announced the announcement of new tariffs.
Alphabet’s latest rally eases concerns about a forced breakup after a ruling in Washington in September. A judge rejected the U.S. Justice Department call on Google to divest its Chrome browser and Android mobile operating system after the decision the company created an illegal monopoly in searches. Stocks soared to record highs that day, and President Trump personally congratulated letter CEO Sundar Pichai at the White House dinner: “Well, you had a really good yesterday. Google had a very good yesterday.”
The company has not completely avoided regulatory scrutiny. Earlier this month, EU regulators fined nearly €3 billion for misusing their dominance in advertising technology.
Even so, Alphabet outperformed expectations throughout 2025. Revenue reached $96 billion in the second quarter, including 12% growth in Google’s search service to $54.2 billion, while YouTube ad sales beat forecasts. Cloud revenues grew by nearly one-third to $13.6 billion, further cementing the group’s dominance in multiple digital markets.
AI remains at the heart of the company’s growth story. Pichai said in July that Google’s AI “Overview” software is now used by 1.5 billion people, while its multi-mode AI assistant Gemini continues to expand. “We are leading at the boundaries of AI and transporting at an incredible speed. AI is actively affecting every part of the business, driving a strong momentum,” he told investors.
The stock’s rise is closely linked to a U.S. market rally ahead of the Fed’s policy meeting this week, when a quarter-point reduction rate will be confirmed.
Alphabet shares closed at 10.81 points, or 4.49%, on Monday, at $251.61.
