Alphabet Edges Toward $4 Trillion Valuation After Record Stock Surge
Alphabet, Google’s parent company, is rapidly closing in on a $4 trillion valuation after its stock surged to an all-time high of $315.90 on Monday. The company ended the day with a strong market capitalization of $3.82 trillion, positioning it to soon join an exclusive list of corporations that have crossed the $4 trillion threshold.
If Alphabet succeeds, it will become the fourth company in history to reach the milestone, alongside Apple, Microsoft, and Nvidia, though only Apple and Nvidia remain above that mark today.
AI Breakthroughs and Cloud Growth Drive Record Gains
Alphabet’s rise in 2025 has been fueled by two major growth engines:
1. Rapid expansion of Google Cloud
The company’s cloud division has seen robust enterprise adoption, contributing substantially to overall revenue growth.
2. Alphabet’s momentum in artificial intelligence
The rollout of Gemini 3, Google’s latest AI model, has strengthened the company’s competitive edge in the AI market, increasing investor enthusiasm for long-term gains.
Alphabet’s stock has gained nearly 70% in 2025, outperforming major rivals including Microsoft and Amazon.
Berkshire Hathaway Interest Sparks Investor Optimism
Analysts attribute part of Alphabet’s rally to the market reaction surrounding Berkshire Hathaway’s investment in the company.
Steve Sosnick, Chief Market Analyst at Interactive Brokers, noted that Berkshire’s involvement has encouraged more investors to follow suit.
“The mindset remains that anything Berkshire touches is worth copying — and historically, that has worked,” Sosnick said.
Analysts also highlight Alphabet’s growing strength in developing its own AI hardware, offering an internal alternative to Nvidia’s high-priced chips.
Antitrust Win Strengthens Alphabet’s Position
Alphabet’s upward momentum follows a significant victory in its U.S. antitrust case. On September 2, a federal judge denied the government’s request to force Google to sell its Chrome browser, although the company must implement measures to support greater competition in online search.
This ruling followed an August 2024 decision that found Google maintained a monopoly through exclusive, multi-billion-dollar distribution deals. Avoiding a forced Chrome divestment was a major relief for Alphabet, helping restore investor confidence.
Google’s Vice President of Regulatory Affairs, Lee-Anne Mulholland, said the ruling reinforces the company’s stance that the tech ecosystem remains competitive and that AI is reshaping how people choose digital services.
A Pivotal Moment for Alphabet
Experts say the case marks one of the most impactful antitrust rulings in over 20 years. A breakup of Google’s services could have drastically changed the company’s trajectory, but the favorable outcome leaves Alphabet stronger at a time of unprecedented AI and cloud growth.
With legal uncertainties easing, investor interest rising, and AI advancements accelerating, Alphabet stands on the cusp of joining the world’s most valuable companies in the $4 trillion club.
