Alphabet (GOOGL) shares reached a fresh 52-week high of $256 on Sept. 19, pushing the company's market capitalization higher. Google had hit the $3 trillion mark for the first time last week, fueled by easing regulatory headwinds, particularly a recent antitrust ruling that spared Google from divesting flagship assets such as Chrome and Android. Meanwhile, growth in its cloud business and the increasing traction of its artificial intelligence (AI) products, including the Gemini suite, are providing fresh tailwinds.
Google has now become only the fourth publicly listed firm to achieve that market value, joining Apple (AAPL), Microsoft (MSFT), and Nvidia (NVDA). The milestone reflects growing investor conviction that the company is undergoing a long-term shift from being primarily a search leader to establishing itself as a comprehensive AI powerhouse.
