Alphabet briefly touched a $4 trillion market valuation on Monday, as investors rewarded the Google parent for its strong focus on artificial intelligence and long-term growth.
Its Class-A shares climbed as much as 1.7% to $334.04, hitting a record high before easing slightly.
The company’s growth is underlined by a multi-year deal with Apple, which will use Google’s Gemini platform for its next-generation AI models.
Samsung also plans to double the number of devices powered by Gemini in 2026, showing the platform’s influence in consumer technology.
Meanwhile, Google Cloud posted a 34% revenue jump in the third quarter, with a $155 billion backlog in contracts.
Alphabet has also started renting out its custom AI chips to external customers, and Meta is reportedly considering a multi-billion-dollar deal to buy them starting in 2027.
Alphabet recently surpassed Apple in market valuation for the first time since 2019, becoming the second most valuable company in the world behind Microsoft. It joins Nvidia, Microsoft, and Apple in the exclusive $4 trillion club.
Investor confidence has been further boosted by Berkshire Hathaway’s rare investment in the company and a September court ruling that allowed Alphabet to retain control of Chrome and Android.
“The one name that has surprised us all over the last 12 months is Alphabet,” said Phil Blancato, CEO of Ladenburg Thalmann Asset Management.
“What I would give the company credit for is innovation. That’s what they’ve done to separate them from a lot of other firms in recent days, and you’re seeing it in earnings data.”
Alphabet’s advertising business remains steady despite economic challenges, while new AI offerings, including the well-reviewed Gemini 3 model, are strengthening competition with other AI companies.
