TLDR
- Billionaire Stanley Druckenmiller bought shares of Alphabet and Amazon for the second quarter in a row
- He increased his Alphabet stake by 277% and Amazon stake by 69% in Q4
- Druckenmiller sold out of Nvidia and Palantir earlier and shifted to these two names
- Google Cloud grew revenue 48% and AWS reaccelerated to 24% growth year-over-year
- Both stocks are trading at steep discounts to their five-year average cash flow multiples
Stanley Druckenmiller, the billionaire behind Duquesne Family Office, added more shares of Alphabet and Amazon in the fourth quarter of 2025. It was the second straight quarter he bought both stocks.
His 13F filing with the SEC showed he added 282,800 shares of Alphabet’s Class A stock and 300,870 shares of Amazon. That pushed his Alphabet position up 277% and his Amazon position up 69%.
Druckenmiller built his reputation with roughly 30% annualized returns from 1981 to 2010. His moves are closely watched by institutional investors.
He had previously held Nvidia and Palantir but sold both positions. He has since moved that attention to Alphabet and Amazon.
The appeal of both companies centers on their cloud platforms. Alphabet runs Google Cloud, the world’s third-largest cloud infrastructure service. Amazon runs AWS, the global leader.
AI Is Driving Cloud Growth
Google Cloud posted 48% revenue growth in Q4. AWS saw its growth rate reaccelerate to 24% compared to the same period a year earlier.
Both platforms are adding generative AI tools and large language model features. That is pulling in new enterprise customers and expanding existing contracts.
Alphabet also holds around 90% of global internet search market share through Google. Amazon runs the dominant online retail marketplace in the United States.
These are not pure AI plays. Both companies have large, stable revenue bases outside of their cloud divisions.
Valuations Look Cheap Relative to History
Alphabet is currently trading at 14.3 times its projected 2027 cash flow. Amazon is even lower at 9.7 times estimated cash flow for that year.
Compared to their five-year averages, Alphabet is at a 20% discount and Amazon is at a 48% discount. That makes both stocks historically cheap on a cash flow basis.
PwC has estimated AI will add more than $15 trillion in global economic value by 2030. Druckenmiller’s buys suggest he sees Alphabet and Amazon as core beneficiaries of that shift.
His Q4 filing also showed a 29% reduction in Taiwan Semiconductor Manufacturing. That move reflects a rotation away from chip-focused names and toward AI application companies.
The 13F data covers positions as of the end of Q4 2025 and was filed by the February 17, 2026 deadline.
