Alphabet, Google’s parent company, is set to become the fourth company to surpass the $4 trillion valuation. The company ended Monday at a market capitalisation of $3.82 trillion while shares rose more than 5% to hit a record high of $315.90.
The Big Tech company has experienced a significant rise in its cloud business, which has been a key driver of growth in 2025. Alphabet is also experiencing a push in the artificial intelligence space, as Google is well-positioned in the race with the recent launch of Gemini 3.
While Alphabet’s stock rose by 5% on Monday, the company has now climbed nearly 70% in 2025, more than AI rivals Microsoft and Amazon. As Alphabet is set to enter the $4 trillion market capitalisation club, it will join Nvidia, Microsoft, and Apple, who have previously reached a $4 trillion valuation. However, only Nvidia and Apple remain on the list.
Experts attributed the company’s stock performance to Berkshire Hathaway’s CEO, Warren Buffett, as an investor, and the strong early reviews on its AI models. Chief market analyst at Interactive Brokers, Mr Steve Sosnick, explained that Berkshire’s stake has been drawing investors to Google’s parent company.
“Even though it’s doubtful Warren Buffett had any role in this purchase… the market is still in the mindset of anything Berkshire does is worth emulating, and to be fair, that’s working for a long time,” Steve said.
According to him, Google is on a path to lead the AI race, attributed to its in-house chips that serve as an alternative to Nvidia’s costly processors. Its internet search business is also expected to keep the momentum with the integration of AI.
Alphabet’s Rise Amid Google’s Antitrust Case Victory
Alphabet’s positioning to hit the $4 trillion mark follows Google’s antitrust judgment. In the September 2 verdict, the US judge rejected the government’s demand that Google sell its Chrome web browser but imposed requirements to restore competition in the online search market.
The case comes after Judge Amit Mehta found in August 2024 that Google illegally monopolized the online search market through exclusive distribution of agreements worth billions of dollars annually. For Google, preventing a divestment in its business was a major victory that further fueled investors’ confidence in the company.
Google’s Vice President of Regulatory Affairs, Lee-Anne Mulholland, mentioned that the US Court verdict underlines what the company has been reiterating: that competition is intense and people have the choice of the service they want. She added that the case illustrates how the industry has changed through the advent of AI.
The case was described as one of the most significant rulings against corporate monopoly practices in two decades. Experts noted that forcing Google to sell its Chrome business could have reshaped the tech giant’s future.
