Stanley Druckenmiller Trims Sandisk, Reallocates into TSMC, Amazon, and Alphabet

Prominent hedge fund manager Stanley Druckenmiller adjusted his equity strategy during the second quarter, reallocating capital away from memory manufacturing toward major corporations powering the artificial intelligence infrastructure expansion. According to quarterly portfolio disclosures analyzed in reporting from Yahoo Finance, Druckenmiller's firm, Duquesne Family Office, scaled back its stake in Sandisk while establishing and expanding positions in Taiwan Semiconductor Manufacturing Co., Amazon, and Alphabet.

The institutional portfolio changes were detailed in mandatory Form 13-F filings submitted to the U.S. Securities and Exchange Commission. Investment entities controlling more than $100 million in qualifying assets must submit these reports within 45 days following the end of each calendar quarter. While 13-F data provides a backward-looking glance at institutional activity, it offers clear visibility into the long-term thematic positioning of top-tier fund managers like Druckenmiller.

Duquesne chose to trim its exposure to Sandisk following a strong price rally for the memory chip producer during the first half of the year. The decision allowed the firm to take profits after the stock's significant run-up and redirect those resources toward tech enterprises positioned at the core of AI computational hardware and enterprise cloud capacity.

The largest boost among Duquesne's existing holdings went to Taiwan Semiconductor Manufacturing Co. Druckenmiller raised the fund's equity stake in TSMC by 19% during the second quarter. The additional purchase elevated the Taiwanese chip fabricator to Duquesne's second-largest overall equity position, reflecting strong conviction in the world's primary manufacturer of advanced logic chips necessary for modern AI workloads.

Alongside its increased semiconductor allocation, Duquesne expanded its exposure to cloud hyperscalers. The family office significantly built up its position in e-commerce and cloud provider Amazon, expanding the holding to represent nearly 3% of the firm's total investment portfolio.

Alphabet was introduced as a brand-new addition to Duquesne's equity portfolio during the second quarter. Druckenmiller initiated a fresh position in the Google parent company that now accounts for roughly 2.75% of the fund's overall holdings. The entry marks a dual commitment to the dominant cloud platforms competing for enterprise AI infrastructure dominance.

Both Amazon and Alphabet are benefiting from accelerating demand across their respective cloud divisions, Amazon Web Services and Google Cloud, which provide the server processing capability required to train and run generative AI systems. To sustain that momentum, both technology companies have scheduled at least $200 billion in capital expenditures this year, focused primarily on constructing and equipping advanced data center facilities.

Because the financial returns from these massive capital outlays are expected to accumulate across upcoming reporting periods, institutional investors are locking in exposure before full operational monetization reaches balance sheets. Druckenmiller's recent portfolio moves emphasize a clear pivot toward companies supplying the hardware backbone and computational power driving the broader artificial intelligence market.
