Sergey Brin, co-founder of Google, has recently overtaken Jeff Bezos to become the world’s fourth-richest individual, with an estimated net worth of $240 billion. This significant shift in global wealth rankings follows a notable rise in Alphabet’s stock price, driven largely by the success of Google’s latest AI model, Gemini 3.
On December 9, 2025, Alphabet’s shares closed at $317, experiencing an increase of over 1% for the day. This rise forms part of a 10% increase over the past 30 days, spurred by Gemini 3’s strong performance in comparison to industry standards, especially those set by OpenAI’s ChatGPT.
Since launching in November, Gemini 3 has outperformed rivals in tasks such as trivia, mathematics, and coding, all without relying on Nvidia’s graphics processing units for training. This achievement has alleviated investor concerns about a potential AI bubble.
The U.S. Department of Defense has also selected Gemini 3 for its generative AI platform, highlighting the model’s promising capabilities and its potential applications across various sectors.
Brin’s new ranking places him ahead of Bezos, whose net worth is approximately $239.9 billion, while Elon Musk remains the world’s richest person at about $491 billion, followed by Oracle’s Larry Ellison and Google’s Larry Page.
This shift underlines the growing influence of AI advancements in the technology sector, emphasizing the increasing investment and interest in these technologies. Brin’s ascent in wealth not only reflects his personal success but also signifies a broader trend in which AI is reshaping both the technology landscape and the global economy.
