In the third quarter of 2025, Bill Ackman reduced his stake in Alphabet Class A shares by 9.7%, making a cautious move despite Wall Street’s bullish outlook on the stock. The billionaire investor holds 11 stocks in his hedge fund, with a focus on AI-related companies like Amazon and Uber. Ackman’s decision to sell over 519,000 shares of Alphabet Class A raised eyebrows, but he hasn’t publicly commented on the move.

Alphabet’s strong financial performance in Q3, with revenue reaching $102.3 billion and earnings soaring 33%, has solidified its position as a top AI player. Wall Street analysts unanimously recommend buying Alphabet shares, praising the company’s business growth and AI innovations. Google Search, Google Cloud, and AI features like generative AI and large language models are driving Alphabet’s success.

Despite Ackman’s reduction in Pershing Square’s position in Alphabet Class A, the stock’s long-term potential remains promising. Google Cloud’s recent launch of Gemini 3.0 and advancements in agentic AI and quantum computing could further drive Alphabet’s growth. With Pershing Square still holding over 11 million shares of Alphabet, investors may find value in the stock for the future.
