Legendary investor Stanley Druckenmiller's Duquesne Family Office significantly increased its stake in Amazon (AMZN) during the second quarter of 2026. According to regulatory filings, the firm's position grew by over 1,000%, from 45,800 shares to 541,600 shares. This substantial purchase made Amazon a top-10 holding for the influential investor. It's important to note that this information comes from a delayed 13F filing, which discloses positions held as of June 30, 2026, and does not reflect trading activity since that date.
This move was part of a broader portfolio reshuffle that saw Duquesne increase its exposure to mega-cap technology companies. While boosting its Amazon holdings, the firm also established a new position in Alphabet and exited stakes in several semiconductor companies, including Intel and Micron Technology. The increased bet on Amazon suggests a bullish outlook on the e-commerce and cloud computing giant, particularly its role in artificial intelligence infrastructure through Amazon Web Services (AWS).
