Alphabet Hits $4 Trillion Valuation

Alphabet, the company that owns Google, has become one of the most valuable companies in the world, worth $4 trillion.

This happened because Apple chose to use Alphabet's AI technology, called Gemini, for its Siri assistant.

Investors are excited about Alphabet's progress in artificial intelligence, which has made the company's stock price go up.

Alphabet is now one of only a few companies to ever reach this huge valuation.

Other companies like Nvidia, Microsoft, and Apple have also reached this milestone, but they have since dropped below it.

Alphabet's success is seen as a big win in the AI industry, and it's making investors feel good about the company's future.

The company's AI advancements, including the Gemini model and tensor processing units, have eased concerns about competition.

Alphabet's stock has surged about 65% in 2025, outperforming its peers on Wall Street's elite group of stocks, the so-called Magnificent Seven.

The company's cloud unit has also seen significant growth, with revenue jumping 34% in the third quarter and a backlog of sales contracts rising to $155 billion.

Additionally, Meta is in talks to spend billions on Alphabet's AI chips for its data centers starting in 2027.

Alphabet's advertising business has remained steady despite economic uncertainty and intense competition.

The company has also benefited from a U.S. judge's ruling against breaking it up, allowing it to retain control of its Chrome browser and Android mobile operating system.
