Google-parent Alphabet may soon join Apple, Microsoft and Nvidia in $4 Trillion exclusive club

Google-parent company Alphabet may soon become a $4 trillion company – only the fourth corporation in history to reach this market capitalisation. The tech giant is riding a rally fueled by artificial intelligence (AI), boosted by an antitrust ruling delivered by a judge, saying the company doesn't need to divest its Chrome browser business. According to a report by news agency Reuters, shares of Alphabet surged more than 5% on Monday (November 24), giving the company a market capitalisation of $3.82 trillion.

Notably, the company’s stock has climbed nearly 70% so far this year, significantly outpacing AI rivals like Microsoft and Amazon.com. The exclusive “$4 Trillion Club” has previously included Nvidia, Microsoft and Apple, though only Nvidia and Apple currently maintain that valuation. At the time of writing, Alphabet ($3.62 trillion) even has more market capitalisation than Microsoft ($3.51 trillion).

AI reversal and antitrust ruling

The surge reflects a massive reversal in investor sentiment. After the launch of ChatGPT in 2023, many investors feared Alphabet had lost its AI edge, despite inventing much of the underlying generative AI technology. Alphabet has regained momentum by transforming its cloud business into a key growth driver and receiving strong early reviews for its powerful new Gemini 3 model. The company's recent success also attracted investment from Warren Buffett’s Berkshire Hathaway.

Furthermore, Google shares have rallied as Big Tech largely emerged unscathed from the bipartisan antitrust push initiated during US President Donald Trump’s first term. The company notably sidestepped a court-ordered breakup after its search business was found to be an illegal monopoly. Notably, Alphabet crossed the $3 trillion mark in September. Analysts further believe that Google is well-positioned in the AI race due to its “full stack” advantage.
