Billionaire Stanley Druckenmiller Sells Micron and Is Piling Into This Other Unstoppable Artificial Intelligence (AI) Chip Stock Instead

Billionaire investor Stanley Druckenmiller's Duquesne Family Office completely exited its Micron Technology position in Q2 2026 after the stock rallied 231% year-to-date, while simultaneously initiating a new stake in Advanced Micro Devices (AMD). Druckenmiller appears to view memory chips as a cyclical, mature trade with limited upside, while seeing AMD as better positioned for long-term AI infrastructure growth as it gains market share against Nvidia.
