Sep 15 – Alphabet (NASDAQ:GOOGL) crossed a historic milestone on Monday as its market capitalization moved above $3 trillion for the first time. The company became only the fourth U.S. firm to achieve this level, alongside Nvidia (NASDAQ:NVDA), Microsoft (NASDAQ:MSFT), and Apple (NASDAQ:AAPL).
Shares of Alphabet gained as much as 4.7% intraday, reaching $252.7, which pushed the stock into the $3 trillion tier. The company’s stock has advanced more than 30% in 2025, driven by optimism around artificial intelligence and relief following a favorable antitrust ruling. Earlier this month, a judge determined that Alphabet does not need to spin off its Chrome browser, easing concerns of a structural breakup.
The new valuation highlights the growing influence of AI-focused technology leaders. Nvidia has surged on demand for its GPUs, Microsoft continues to benefit from its cloud services, and Apple maintains its premium positioning in consumer devices. Alphabet now stands firmly among them, signaling investor confidence in its growth path despite regulatory challenges.
With this move, Alphabet’s inclusion in the $3 trillion club underscores the strength of mega-cap tech in shaping overall market momentum.
