Alphabet becomes fourth company to reach $3 trillion market cap

Alphabet has joined the $3 trillion club.

Shares of the search giant jumped more than 4% on Monday, pushing the company into territory occupied only by Nvidia, Microsoft and Apple.

The stock got a big lift in early September from an antitrust ruling by a judge, whose penalties came in lighter than shareholders feared. The U.S. Department of Justice wanted Google to be forced to divest its Chrome browser, and last year a district court ruled that the company held an illegal monopoly in search and related advertising.

But Judge Amit Mehta decided against the most severe consequences proposed by the DOJ, which sent shares soaring to a record. After the big rally, President Donald Trump congratulated the company and called it "a very good day."

Alphabet shares are now up more than 30% this year, compared to the 15% gain for the Nasdaq.

The $3 trillion milestone comes roughly 20 years after Google's IPO and a little more than 10 years after the creation of Alphabet as a holding company, with Google its prime subsidiary.

CEO Sundar Pichai was named CEO of Alphabet in 2019, replacing co-founder Larry Page. Pichai's latest challenge has been the surge of new competition due to the rise of artificial intelligence, which the company has had to manage through while also fending off an aggressive set of regulators in the U.S. and Europe.

The rise of Perplexity and OpenAI ended up helping Google land the recent favorable antitrust ruling. The company's hopes of becoming a major AI player largely ride with Gemini, Google's flagship suite of AI models.
