Alphabet, Google’s Parent Company, Achieves Historic Milestone

Alphabet, the parent company of Google, reached a market capitalization of $3 trillion for the first time on Monday morning, driven by renewed optimism around artificial intelligence (AI) and a favorable antitrust ruling.

Stock Performance

Alphabet’s Class A shares rose 4.6% to $251.88, while Class C shares gained 4.5% to $252.30, both trading at all-time highs.

Joining the $3 Trillion Club

Alphabet joined other tech giants like Apple, the iPhone manufacturer, and Microsoft in reaching a $3 trillion valuation. Nvidia, an AI leader, has surpassed the $4 trillion mark.

Key Factors Behind Alphabet’s Success

A significant boost for Google’s parent company came from a U.S. federal court ruling that allowed Alphabet to maintain control over its Chrome browser and Android operating system. This decision is crucial for the tech giant, as its dominance in search and mobile ecosystems has long been under scrutiny.

Investor confidence was further bolstered by Alphabet’s cloud computing unit reporting nearly a 32% increase in second-quarter revenue, surpassing expectations as investments in self-designed chips and the Gemini AI model began to pay off.
