Stanley Druckenmiller’s Duquesne Family Office executed a dramatic portfolio rotation in the second quarter, increasing its Amazon stake by more than 1,000% to 541,600 shares while completely exiting semiconductor positions in Micron, Intel, and Broadcom, according to a regulatory 13F filing released August 17.
The moves marked a sharp reversal from Q1, when Druckenmiller had slashed his Amazon position by 94% and exited Alphabet entirely. In Q2, he not only rebuilt Amazon to roughly $129 million in value but also opened a new $120 million position in Alphabet and added stakes in Advanced Micro Devices and other AI infrastructure plays, according to Quartz and CNBC reporting.
The semiconductor exits were substantial. Druckenmiller disposed of 23,400 Micron shares and 411,400 Intel shares, even as those stocks surged during the quarter—Intel climbed from the mid-$40 range to a peak of $141, while Micron’s price more than tripled over Q2, according to the Quartz article. Broadcom was also liquidated entirely.
Beyond the mega-cap tech bets, Druckenmiller’s Q2 rotation extended to aviation and data-center infrastructure. He initiated a 603,000-share position in Delta Air Lines and nearly tripled his United Airlines stake to around 795,000 shares. For data-center exposure, Duquesne acquired over 4 million shares of Bitdeer Technologies Group and took a new 754,800-share stake in Riot Platforms, according to Benzinga and Investing.com coverage.
A Shift in AI Infrastructure Strategy
The portfolio reshuffling reflected a recalibration within AI semiconductor exposure. Druckenmiller boosted his stake in Taiwan Semiconductor Manufacturing Co. by 19% to $282 million and increased STMicroelectronics by nearly 19% to $232 million, making those two chipmakers his second- and third-largest common stock holdings by the end of June, according to CNBC. The pattern suggested a pivot away from broad-based semiconductor bets toward what analysts described as AI infrastructure bottlenecks and cloud-computing plays.
The timing was notable: the purchases occurred during a blistering Q2 rally in technology and semiconductor shares fueled by enthusiasm around AI spending. However, many of those winners reversed sharply in July as investors questioned lofty valuations and the sustainability of the AI infrastructure boom. The 13F filing reflects holdings only as of June 30, leaving unclear whether Druckenmiller held positions through the July sell-off or adjusted his exposure afterward.
Druckenmiller’s Duquesne portfolio stood at $5.21 billion with 90 positions at the end of Q2. Clinical genetic testing company Natera remained his top holding, valued at more than $800 million. His macro-focused strategy—built over decades of bold bets on currency movements and economic cycles—has made him one of Wall Street’s most closely followed investors. He rose to fame after helping execute George Soros’ roughly $10 billion bet against the British pound in 1992 and later oversaw about $12 billion as president of Duquesne Capital Management before closing the hedge fund in 2010 and converting to a family office structure.
