Alphabet Nears Historic $4 Trillion Market Cap Milestone
Google’s parent company Alphabet is on the verge of joining the exclusive $4 trillion market capitalisation club, becoming only the fourth company in history to achieve this milestone. The tech giant’s stock surge is driven by AI momentum and a favorable antitrust ruling.
Key Takeaways
- Alphabet’s market cap reached $3.82 trillion after 5% stock surge
- Stock has climbed nearly 70% year-to-date, outpacing Microsoft and Amazon
- Company positioned to join Nvidia and Apple in $4 trillion club
According to Reuters, Alphabet shares surged more than 5% on Monday, pushing its market valuation to $3.82 trillion. The company’s stock has climbed nearly 70% this year, significantly outperforming AI rivals Microsoft and Amazon.
At current levels, Alphabet’s $3.62 trillion valuation even exceeds Microsoft’s $3.51 trillion market cap. The exclusive $4 trillion club has previously included Nvidia, Microsoft and Apple, though only Nvidia and Apple currently maintain that valuation.
AI Comeback and Legal Victories
The surge represents a dramatic reversal in investor sentiment. After ChatGPT’s launch in 2023, many feared Alphabet had lost its AI leadership despite pioneering much generative AI technology.
Alphabet 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 rallied as Big Tech emerged largely unscathed from bipartisan antitrust efforts. The company notably avoided a court-ordered breakup despite its search business being ruled an illegal monopoly.
Alphabet crossed the $3 trillion mark in September. Analysts believe Google is well-positioned in the AI race due to its “full stack” advantage spanning hardware, software, and data infrastructure.
