A Big Bet on AI and Tech Infrastructure
The most prominent theme in the second-quarter filing is a deep conviction in the technology powering the AI revolution. Duquesne established a new $132.7 million position in Entegris, a critical supplier of materials for the semiconductor industry.
This was complemented by a new $99.9 million stake in Microsoft, a leader in cloud computing and AI software. Druckenmiller also initiated a position in chipmaker Broadcom Inc. AVGO and significantly increased his holding in Taiwan Semiconductor, adding over 166,000 shares to make it a $173 million position.
This collection of moves indicates a broad bet on the entire AI value chain, from chip designers and manufacturers to software giants that deploy the technology.
Rotating Into Big Banks
Druckenmiller also repositioned his financial holdings, moving out of consumer-focused credit and into systemically important global banks. The firm completely sold its $35.4 million stake in Capital One.
In its place, Duquesne initiated several new positions, including $56.7 million in Citigroup, $29.7 million in Goldman Sachs Group Inc. GS, and a $51.6 million position in the Financial Select Sector SPDR Fund XLF, a broad bet on the entire sector. These moves suggest a belief that large, diversified banks are better positioned for the current economic environment.
Bullish On The U.S. Market
Beyond individual stocks, Druckenmiller made a significant macro statement by purchasing call options on two major U.S. stock indices. The filing shows a new $72.3 million call position on the iShares Russell 2000 ETF, a bet on a rally in small-cap stocks, which are often seen as a barometer for the health of the domestic economy.
He coupled this with a $55.6 million call position on the SPDR S&P 500 ETF Trust SPY, signaling broad market optimism. For a macro investor of Druckenmiller’s stature, taking such direct positions is a clear and confident signal of his economic outlook.
Other Notable Moves
Among other changes, Duquesne significantly trimmed its stake in South Korean e-commerce leader Coupang, selling nearly 5.2 million shares. Conversely, the firm more than doubled its investment in biotech company Insmed, making it one of the portfolio’s largest holdings at $226.8 million.
Price Action
The SPDR S&P 500 ETF Trust SPY and Invesco QQQ Trust ETF QQQ, which track the S&P 500 index and Nasdaq 100 index, respectively, fell on Friday. The SPY was down 0.23% at $643.44, while the QQQ declined 0.44% to $577.34, according to Benzinga Pro data.
On Monday, the futures of the S&P 500, Nasdaq 100, and Dow Jones indices were trading mixed.
