Pershing Square Capital Management’s significant position in Alphabet has generated roughly $2.04 billion in combined gains since the end of Q3 2025. Founder Bill Ackman initially acquired over 10 million shares across both Class C and Class A stock in early 2023 when the shares were trading between $85 and $109. By September 30, 2025, his remaining holdings—6.3 million Class C and 4.8 million Class A shares—were valued at nearly $2.72 billion. Following a roughly 30% rally through December and January, the stake’s value climbed to about $3.7 billion, marking a 75% uplift over four months and underscoring Ackman’s call on Alphabet as undervalued at entry.

Alphabet is pioneering "agentic shopping" through its Universal Commerce Protocol, which allows advanced AI models to query product catalogs from major retailers without the risk of misinformation. According to Morgan Stanley, AI-driven e-commerce could reach $385 billion in the U.S. by 2030. By integrating its Gemini model into the core Shopping tab and leveraging Chrome and Search usage, Alphabet aims to convert impulse purchase behavior into a new revenue stream, potentially siphoning share from incumbent online marketplaces.

Wall Street consensus forecasts call for 15% year-over-year revenue growth in Q4 2025, with EPS climbing roughly 24%. Advertisers remain committed to search and video channels, while Google Cloud—already delivering 34% growth in Q3—expanded its operating margin from 17% to 24%. Investors will watch for commentary on the commercial rollout of Gemini services and any updates to capital expenditure plans for additional data-center capacity, both of which could drive further margin expansion in 2026.

Alphabet’s quantum research team has demonstrated that its custom "Willow" qubit processor can reduce error rates exponentially as system size increases. In late 2025, the company ran a benchmark algorithm whose output was verified against classical supercomputers, achieving a performance milestone that surpassed conventional machines on a specialized task. Continued progress toward fault-tolerant quantum hardware could position Alphabet to monetize quantum-as-a-service offerings alongside its existing cloud infrastructure.
