Stanley Druckenmiller's Duquesne Family Office reshaped its portfolio in the second quarter of 2026, raising reported assets under management to about $5.21 billion across 95 holdings, with the top 10 positions accounting for 45.83% of the total. The filing showed a rotation away from legacy chipmakers and toward digital infrastructure tied to Bitcoin mining and AI compute: Duquesne exited 411,400 Intel shares and 23,400 Micron Technology shares, opened a 4.07 million-share position in Bitdeer Technologies, bought 754,800 shares of Riot Platforms, 314,150 shares of Hut 8 and 87,100 shares of IREN, and re-established a 336,300-share stake in Alphabet after exiting it in the first quarter. It also disclosed AMD exposure and Lam Research exposure, reinforcing a view that Druckenmiller remains invested in the AI buildout while shifting toward businesses with potential upside from power, data center and hybrid compute demand rather than using a spot Bitcoin ETF for simple price exposure.
