Alphyn Capital Management stated the following regarding Alphabet Inc. (NASDAQ:GOOG) in its third quarter 2025 investor letter:
“Alphabet Inc.’s (NASDAQ:GOOG) shares rose this quarter, partly driven by the resolution of a major regulatory overhang. On September 2nd, Judge Mehta issued the remedies decision in the DOJ antitrust case concerning Search. The outcome was far less severe than feared, as the court rejected the most draconian measures, including the structural divestiture of Chrome or Android and a broad ban on distribution payments. While Google is now restricted from paying for exclusive default placement (e.g., with Apple), it can still compensate partners for non-exclusive default status. The enacted remedies, which include tailored data sharing and syndication on commercial terms, appear manageable.
With one major legal overhang out of the way (another case on the Ad tech monopoly remains outstanding), focus can now return to Alphabet’s fundamentals, particularly its strong positioning in Artificial Intelligence. Google’s advantage lies in its vertically integrated stack, spanning proprietary infrastructure (TPUs), leading models (Gemini), and scaled global distribution platforms (Search, Android). This full-stack approach allows for optimization and efficiency that competitors cannot easily match; for example, Google claims it has twice the power efficiency of competitors and a 33x efficiency in inference, demonstrating its progress in managing the cost of AI deployment. AI is enhancing Search utility through features like AI Overviews and Lens, driving increased user engagement. Additionally, Google Cloud is rapidly gaining traction, now exceeding a $50 billion annual run rate (growing 32% YoY) with a $106 billion backlog, as enterprises choose Google for its differentiated AI capabilities. This leadership is evident in Google’s support for 9 of the top 10 AI labs and its processing roughly 4x the token volume of other providers. The company continues to deliver strong financial performance, with 14% revenue growth and strong operating margins in the last quarter, allowing it to fund an aggressive $85 billion capex plan for AI infrastructure.”
